# Sql driver mock for Golang
**sqlmock** is a mock library implementing [sql/driver](https://godoc.org/database/sql/driver). Which has one and only
purpose - to simulate any **sql** driver behavior in tests, without needing a real database connection. It helps to
maintain correct **TDD** workflow.
- this library is now complete and stable. (you may not find new changes for this reason)
- supports concurrency and multiple connections.
- supports **go1.8** Context related feature mocking and Named sql parameters.
- does not require any modifications to your source code.
- the driver allows to mock any sql driver method behavior.
- has strict by default expectation order matching.
- has no third party dependencies.
**NOTE:** in **v1.2.0** **sqlmock.Rows** has changed to struct from interface, if you were using any type references to that
interface, you will need to switch it to a pointer struct type. Also, **sqlmock.Rows** were used to implement **driver.Rows**
interface, which was not required or useful for mocking and was removed. Hope it will not cause issues.
## Install
go get github.com/DATA-DOG/go-sqlmock
## Documentation and Examples
Visit [godoc](http://godoc.org/github.com/DATA-DOG/go-sqlmock) for general examples and public api reference.
See **.travis.yml** for supported **go** versions.
Different use case, is to functionally test with a real database - [go-txdb](https://github.com/DATA-DOG/go-txdb)
all database related actions are isolated within a single transaction so the database can remain in the same state.
See implementation examples:
- [blog API server](https://github.com/DATA-DOG/go-sqlmock/tree/master/examples/blog)
- [the same orders example](https://github.com/DATA-DOG/go-sqlmock/tree/master/examples/orders)
### Something you may want to test, assuming you use the [go-mysql-driver](https://github.com/go-sql-driver/mysql)
``` go
package main
import (
"database/sql"
_ "github.com/go-sql-driver/mysql"
)
func recordStats(db *sql.DB, userID, productID int64) (err error) {
tx, err := db.Begin()
if err != nil {
return
}
defer func() {
switch err {
case nil:
err = tx.Commit()
default:
tx.Rollback()
}
}()
if _, err = tx.Exec("UPDATE products SET views = views + 1"); err != nil {
return
}
if _, err = tx.Exec("INSERT INTO product_viewers (user_id, product_id) VALUES (?, ?)", userID, productID); err != nil {
return
}
return
}
func main() {
// @NOTE: the real connection is not required for tests
db, err := sql.Open("mysql", "root@/blog")
if err != nil {
panic(err)
}
defer db.Close()
if err = recordStats(db, 1 /*some user id*/, 5 /*some product id*/); err != nil {
panic(err)
}
}
```
### Tests with sqlmock
``` go
package main
import (
"fmt"
"testing"
"github.com/DATA-DOG/go-sqlmock"
)
// a successful case
func TestShouldUpdateStats(t *testing.T) {
db, mock, err := sqlmock.New()
if err != nil {

## Customize SQL query matching
There were plenty of requests from users regarding SQL query string validation or different matching option.
We have now implemented the `QueryMatcher` interface, which can be passed through an option when calling
`sqlmock.New` or `sqlmock.NewWithDSN`.
This now allows to include some library, which would allow for example to parse and validate `mysql` SQL AST.
And create a custom QueryMatcher in order to validate SQL in sophisticated ways.
By default, **sqlmock** is preserving backward compatibility and default query matcher is `sqlmock.QueryMatcherRegexp`
which uses expected SQL string as a regular expression to match incoming query string. There is an equality matcher:
`QueryMatcherEqual` which will do a full case sensitive match.
In order to customize the QueryMatcher, use the following:
``` go
db, mock, err := sqlmock.New(sqlmock.QueryMatcherOption(sqlmock.QueryMatcherEqual))
```
The query matcher can be fully customized based on user needs. **sqlmock** will not
provide a standard sql parsing matchers, since various drivers may not follow the same SQL standard.
## Matching arguments like time.Time
There may be arguments which are of `struct` type and cannot be compared easily by value like `time.Time`. In this case
**sqlmock** provides an [Argument](https://godoc.org/github.com/DATA-DOG/go-sqlmock#Argument) interface which
can be used in more sophisticated matching. Here is a simple example of time argument matching:
``` go
type AnyTime struct{}
// Match satisfies sqlmock.Argument interface
func (a AnyTime) Match(v driver.Value) bool {
_, ok := v.(time.Time)
return ok
}
func TestAnyTimeArgument(t *testing.T) {
t.Parallel()
db, mock, err := New()
if err != nil {
t.Errorf("an error '%s' was not expected when opening a stub database connection", err)
}
defer db.Close()
mock.ExpectExec("INSERT INTO users").
WithArgs("john", AnyTime{}).
WillReturnResult(NewResult(1, 1))
_, err = db.Exec("INSERT INTO users(name, created_at) VALUES (?, ?)", "john", time.Now())
if err != nil {
t.Errorf("error '%s' was not expected, while inserting a row", err)
}
if err := mock.ExpectationsWereMet(); err != nil {
t.Errorf("there were unfulfilled expectations: %s", err)
}
}
```
It only asserts that argument is of `time.Time` type.
## Run tests
go test -race
## Change Log
- **2019-02-13** - added `go.mod` removed the references and suggestions using `gopkg.in`.
- **2018-12-11** - added expectation of Rows to be closed, while mocking expected query.
- **2018-12-11** - introduced an option to provide **QueryMatcher** in order to customize SQL query matching.
- **2017-09-01** - it is now possible to expect that prepared statement will be closed,
using **ExpectedPrepare.WillBeClosed**.
- **2017-02-09** - implemented support for **go1.8** features. **Rows** interface was changed to struct
but contains all methods as before and should maintain backwards compatibility. **ExpectedQuery.WillReturnRows** may now
accept multiple row sets.
- **2016-11-02** - `db.Prepare()` was not validating expected prepare SQL
query. It should still be validated even if Exec or Query is not
executed on that prepared statement.
- **2016-02-23** - added **sqlmock.AnyArg()** function to provide any kind
of argument matcher.
- **2016-02-23** - convert expected arguments to driver.Value as natural
driver does, the change may affect time.Time comparison and will be
stricter. See [issue](https://github.com/DATA-DOG/go-sqlmock/issues/31).
- **2015-08-27** - **v1** api change, concurrency support, all known issues fixed.
- **2014-08-16** instead of **panic** during reflect type mismatch when comparing query arguments - now return error
- **2014-08-14** added **sqlmock.NewErrorResult** which gives an option to return driver.Result with errors for
interface methods, see [issue](https://github.com/DATA-DOG/go-sqlmock/issues/5)
- **2014-05-29** allow to match arguments in more sophisticated ways, by providing an **sqlmock.Argument** interface
- **2014-04-21** introduce **sqlmock.New()** to open a mock database connection for tests. This method
calls sql.DB.Ping to ensure that connection is open, see [issue](https://github.com/DATA-DOG/go-sqlmock/issues/4).
This way on Close it will surely assert if all expectations are met, even if database was not triggered at all.
The old way is still available, but it is advisable to call db.Ping manually before asserting with db.Close.
- **2014-02-14** RowsFromCSVString is now a part of Rows interface named as FromCSVString.
It has changed to allow more ways to construct rows and to easily extend this API in future.
See [issue 1](https://github.com/DATA-DOG/go-sqlmock/issues/1)
**RowsFromCSVString** is deprecated and will be removed in future

/*
Package sqlmock is a mock library implementing sql driver. Which has one and only
purpose - to simulate any sql driver behavior in tests, without needing a real
database connection. It helps to maintain correct **TDD** workflow.
It does not require any modifications to your source code in order to test
and mock database operations. Supports concurrency and multiple database mocking.
The driver allows to mock any sql driver method behavior.

CANTO I
IN the midway of this our mortal life,
I found me in a gloomy wood, astray
Gone from the path direct: and e'en to tell
It were no easy task, how savage wild
That forest, how robust and rough its growth,
Which to remember only, my dismay
Renews, in bitterness not far from death.
Yet to discourse of what there good befell,
All else will I relate discover'd there.
How first I enter'd it I scarce can say,
Such sleepy dullness in that instant weigh'd
My senses down, when the true path I left,
But when a mountain's foot I reach'd, where clos'd
The valley, that had pierc'd my heart with dread,
I look'd aloft, and saw his shoulders broad
Already vested with that planet's beam,
Who leads all wanderers safe through every way.
Then was a little respite to the fear,
That in my heart's recesses deep had lain,
All of that night, so pitifully pass'd:
And as a man, with difficult short breath,
Forespent with toiling, 'scap'd from sea to shore,
Turns to the perilous wide waste, and stands
At gaze; e'en so my spirit, that yet fail'd
Struggling with terror, turn'd to view the straits,
That none hath pass'd and liv'd. My weary frame
After short pause recomforted, again
I journey'd on over that lonely steep,
The hinder foot still firmer. Scarce the ascent
Began, when, lo! a panther, nimble, light,
And cover'd with a speckled skin, appear'd,
Nor, when it saw me, vanish'd, rather strove
To check my onward going; that ofttimes
With purpose to retrace my steps I turn'd.
The hour was morning's prime, and on his way
Aloft the sun ascended with those stars,
That with him rose, when Love divine first mov'd
Those its fair works: so that with joyous hope
All things conspir'd to fill me, the gay skin
Of that swift animal, the matin dawn
And the sweet season. Soon that joy was chas'd,
And by new dread succeeded, when in view
A lion came, 'gainst me, as it appear'd,
With his head held aloft and hunger-mad,
That e'en the air was fear-struck. A she-wolf
Was at his heels, who in her leanness seem'd
Full of all wants, and many a land hath made
Disconsolate ere now. She with such fear
O'erwhelmed me, at the sight of her appall'd,
That of the height all hope I lost. As one,
Who with his gain elated, sees the time
When all unwares is gone, he inwardly
Mourns with heart-griping anguish; such was I,
Haunted by that fell beast, never at peace,
Who coming o'er against me, by degrees
Impell'd me where the sun in silence rests.
While to the lower space with backward step
I fell, my ken discern'd the form one of one,
Whose voice seem'd faint through long disuse of speech.
When him in that great desert I espied,
"Have mercy on me!" cried I out aloud,
"Spirit! or living man! what e'er thou be!"
He answer'd: "Now not man, man once I was,
And born of Lombard parents, Mantuana both
By country, when the power of Julius yet
Was scarcely firm. At Rome my life was past
Beneath the mild Augustus, in the time
Of fabled deities and false. A bard
Was I, and made Anchises' upright son
The subject of my song, who came from Troy,
When the flames prey'd on Ilium's haughty towers.
But thou, say wherefore to such perils past
Return'st thou? wherefore not this pleasant mount
Ascendest, cause and source of all delight?"
"And art thou then that Virgil, that well-spring,
From which such copious floods of eloquence
Have issued?" I with front abash'd replied.
"Glory and light of all the tuneful train!
May it avail me that I long with zeal
Have sought thy volume, and with love immense
Have conn'd it o'er. My master thou and guide!
Thou he from whom alone I have deriv'd
That style, which for its beauty into fame
Exalts me. See the beast, from whom I fled.
O save me from her, thou illustrious sage!"
"For every vein and pulse throughout my frame
She hath made tremble." He, soon as he saw
That I was weeping, answer'd, "Thou must needs
Another way pursue, if thou wouldst 'scape
From out that savage wilderness. This beast,
At whom thou criest, her way will suffer none
To pass, and no less hindrance makes than death:
So bad and so accursed in her kind,
That never sated is her ravenous will,
Still after food more craving than before.
To many an animal in wedlock vile
She fastens, and shall yet to many more,
Until that greyhound come, who shall destroy
Her with sharp pain. He will not life support
By earth nor its base metals, but by love,
Wisdom, and virtue, and his land shall be
The land 'twixt either Feltro. In his might
Shall safety to Italia's plains arise,
For whose fair realm, Camilla, virgin pure,
Nisus, Euryalus, and Turnus fell.
He with incessant chase through every town
Shall worry, until he to hell at length
Restore her, thence by envy first let loose.
I for thy profit pond'ring now devise,
That thou mayst follow me, and I thy guide
Will lead thee hence through an eternal space,
Where thou shalt hear despairing shrieks, and see
Spirits of old tormented, who invoke
A second death; and those next view, who dwell
Content in fire, for that they hope to come,
Whene'er the time may be, among the blest,
Into whose regions if thou then desire
T' ascend, a spirit worthier then I
Must lead thee, in whose charge, when I depart,
Thou shalt be left: for that Almighty King,
Who reigns above, a rebel to his law,
Adjudges me, and therefore hath decreed,
That to his city none through me should come.
He in all parts hath sway; there rules, there holds
His citadel and throne. O happy those,
Whom there he chooses!" I to him in few:
"Bard! by that God, whom thou didst not adore,
I do beseech thee (that this ill and worse
I may escape) to lead me, where thou saidst,
That I Saint Peter's gate may view, and those
Who as thou tell'st, are in such dismal plight."
Onward he mov'd, I close his steps pursu'd.

# A pure Go MSSQL driver for Go's database/sql package
[![GoDoc](https://godoc.org/github.com/denisenkom/go-mssqldb?status.svg)](http://godoc.org/github.com/denisenkom/go-mssqldb)
[![Build status](https://ci.appveyor.com/api/projects/status/jrln8cs62wj9i0a2?svg=true)](https://ci.appveyor.com/project/denisenkom/go-mssqldb)
[![codecov](https://codecov.io/gh/denisenkom/go-mssqldb/branch/master/graph/badge.svg)](https://codecov.io/gh/denisenkom/go-mssqldb)
## Install
Requires Go 1.8 or above.
Install with `go get github.com/denisenkom/go-mssqldb` .
## Connection Parameters and DSN
The recommended connection string uses a URL format:
`sqlserver://username:password@host/instance?param1=value&param2=value`
Other supported formats are listed below.
### Common parameters:
* `user id` - enter the SQL Server Authentication user id or the Windows Authentication user id in the DOMAIN\User format. On Windows, if user id is empty or missing Single-Sign-On is used.
* `password`
* `database`
* `connection timeout` - in seconds (default is 0 for no timeout), set to 0 for no timeout. Recommended to set to 0 and use context to manage query and connection timeouts.
* `dial timeout` - in seconds (default is 15), set to 0 for no timeout
* `encrypt`
* `disable` - Data send between client and server is not encrypted.
* `false` - Data sent between client and server is not encrypted beyond the login packet. (Default)
* `true` - Data sent between client and server is encrypted.
* `app name` - The application name (default is go-mssqldb)
### Connection parameters for ODBC and ADO style connection strings:
* `server` - host or host\instance (default localhost)
* `port` - used only when there is no instance in server (default 1433)
### Less common parameters:
* `keepAlive` - in seconds; 0 to disable (default is 30)
* `failoverpartner` - host or host\instance (default is no partner).
* `failoverport` - used only when there is no instance in failoverpartner (default 1433)
* `packet size` - in bytes; 512 to 32767 (default is 4096)
* Encrypted connections have a maximum packet size of 16383 bytes
* Further information on usage: https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/configure-the-network-packet-size-server-configuration-option
* `log` - logging flags (default 0/no logging, 63 for full logging)
* 1 log errors
* 2 log messages
* 4 log rows affected
* 8 trace sql statements
* 16 log statement parameters
* 32 log transaction begin/end
* `TrustServerCertificate`
* false - Server certificate is checked. Default is false if encypt is specified.
* true - Server certificate is not checked. Default is true if encrypt is not specified. If trust server certificate is true, driver accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.
* `certificate` - The file that contains the public key certificate of the CA that signed the SQL Server certificate. The specified certificate overrides the go platform specific CA certificates.
* `hostNameInCertificate` - Specifies the Common Name (CN) in the server certificate. Default value is the server host.
* `ServerSPN` - The kerberos SPN (Service Principal Name) for the server. Default is MSSQLSvc/host:port.
* `Workstation ID` - The workstation name (default is the host name)
* `ApplicationIntent` - Can be given the value `ReadOnly` to initiate a read-only connection to an Availability Group listener. The `database` must be specified when connecting with `Application Intent` set to `ReadOnly`.
### The connection string can be specified in one of three formats:
1. URL: with `sqlserver` scheme. username and password appears before the host. Any instance appears as
the first segment in the path. All other options are query parameters. Examples:
* `sqlserver://username:password@host/instance?param1=value&param2=value`
* `sqlserver://username:password@host:port?param1=value&param2=value`
* `sqlserver://sa@localhost/SQLExpress?database=master&connection+timeout=30` // `SQLExpress instance.
* `sqlserver://sa:mypass@localhost?database=master&connection+timeout=30` // username=sa, password=mypass.
* `sqlserver://sa:mypass@localhost:1234?database=master&connection+timeout=30` // port 1234 on localhost.
* `sqlserver://sa:my%7Bpass@somehost?connection+timeout=30` // password is "my{pass"
A string of this format can be constructed using the `URL` type in the `net/url` package.
```go
query := url.Values{}
query.Add("app name", "MyAppName")
u := &url.URL{
Scheme: "sqlserver",
User: url.UserPassword(username, password),
Host: fmt.Sprintf("%s:%d", hostname, port),
// Path: instance, // if connecting to an instance instead of a port
RawQuery: query.Encode(),
}
db, err := sql.Open("sqlserver", u.String())
```
2. ADO: `key=value` pairs separated by `;`. Values may not contain `;`, leading and trailing whitespace is ignored.
Examples:
* `server=localhost\\SQLExpress;user id=sa;database=master;app name=MyAppName`
* `server=localhost;user id=sa;database=master;app name=MyAppName`
3. ODBC: Prefix with `odbc`, `key=value` pairs separated by `;`. Allow `;` by wrapping
values in `{}`. Examples:
* `odbc:server=localhost\\SQLExpress;user id=sa;database=master;app name=MyAppName`
* `odbc:server=localhost;user id=sa;database=master;app name=MyAppName`
* `odbc:server=localhost;user id=sa;password={foo;bar}` // Value marked with `{}`, password is "foo;bar"
* `odbc:server=localhost;user id=sa;password={foo{bar}` // Value marked with `{}`, password is "foo{bar"
* `odbc:server=localhost;user id=sa;password={foobar }` // Value marked with `{}`, password is "foobar "
* `odbc:server=localhost;user id=sa;password=foo{bar` // Literal `{`, password is "foo{bar"
* `odbc:server=localhost;user id=sa;password=foo}bar` // Literal `}`, password is "foo}bar"
* `odbc:server=localhost;user id=sa;password={foo{bar}` // Literal `{`, password is "foo{bar"
* `odbc:server=localhost;user id=sa;password={foo}}bar}` // Escaped `} with `}}`, password is "foo}bar"
## Executing Stored Procedures
To run a stored procedure, set the query text to the procedure name:
```go
var account = "abc"
_, err := db.ExecContext(ctx, "sp_RunMe",
sql.Named("ID", 123),
sql.Named("Account", sql.Out{Dest: &account}),
)
```
## Reading Output Parameters from a Stored Procedure with Resultset
To read output parameters from a stored procedure with resultset, make sure you read all the rows before reading the output parameters:
```go
sqltextcreate := `
CREATE PROCEDURE spwithoutputandrows
@bitparam BIT OUTPUT
AS BEGIN
SET @bitparam = 1
SELECT 'Row 1'
END
`
var bitout int64
rows, err := db.QueryContext(ctx, "spwithoutputandrows", sql.Named("bitparam", sql.Out{Dest: &bitout}))
var strrow string
for rows.Next() {
err = rows.Scan(&strrow)
}
fmt.Printf("bitparam is %d", bitout)
```
## Caveat for local temporary tables
Due to protocol limitations, temporary tables will only be allocated on the connection
as a result of executing a query with zero parameters. The following query
will, due to the use of a parameter, execute in its own session,
and `#mytemp` will be de-allocated right away:
```go
conn, err := pool.Conn(ctx)
defer conn.Close()
_, err := conn.ExecContext(ctx, "select @p1 as x into #mytemp", 1)
// at this point #mytemp is already dropped again as the session of the ExecContext is over
```
To work around this, always explicitly create the local temporary
table in a query without any parameters. As a special case, the driver
will then be able to execute the query directly on the
connection-scoped session. The following example works:
```go
conn, err := pool.Conn(ctx)
// Set us up so that temp table is always cleaned up, since conn.Close()
// merely returns conn to pool, rather than actually closing the connection.
defer func() {
_, _ = conn.ExecContext(ctx, "drop table #mytemp") // always clean up
conn.Close() // merely returns conn to pool
}()
// Since we not pass any parameters below, the query will execute on the scope of
// the connection and succeed in creating the table.
_, err := conn.ExecContext(ctx, "create table #mytemp ( x int )")
// #mytemp is now available even if you pass parameters
_, err := conn.ExecContext(ctx, "insert into #mytemp (x) values (@p1)", 1)
```
## Return Status
To get the procedure return status, pass into the parameters a
`*mssql.ReturnStatus`. For example:
```
var rs mssql.ReturnStatus
_, err := db.ExecContext(ctx, "theproc", &rs)
log.Printf("status=%d", rs)
```
or
```
var rs mssql.ReturnStatus
_, err := db.QueryContext(ctx, "theproc", &rs)
for rows.Next() {
err = rows.Scan(&val)
}
log.Printf("status=%d", rs)
```
Limitation: ReturnStatus cannot be retrieved using `QueryRow`.
## Parameters
The `sqlserver` driver uses normal MS SQL Server syntax and expects parameters in
the sql query to be in the form of either `@Name` or `@p1` to `@pN` (ordinal position).
```go
db.QueryContext(ctx, `select * from t where ID = @ID and Name = @p2;`, sql.Named("ID", 6), "Bob")
```
### Parameter Types
To pass specific types to the query parameters, say `varchar` or `date` types,
you must convert the types to the type before passing in. The following types
are supported:
* string -> nvarchar
* mssql.VarChar -> varchar
* time.Time -> datetimeoffset or datetime (TDS version dependent)
* mssql.DateTime1 -> datetime
* mssql.DateTimeOffset -> datetimeoffset
* "github.com/golang-sql/civil".Date -> date
* "github.com/golang-sql/civil".DateTime -> datetime2
* "github.com/golang-sql/civil".Time -> time
* mssql.TVP -> Table Value Parameter (TDS version dependent)
## Important Notes
* [LastInsertId](https://golang.org/pkg/database/sql/#Result.LastInsertId) should
not be used with this driver (or SQL Server) due to how the TDS protocol
works. Please use the [OUTPUT Clause](https://docs.microsoft.com/en-us/sql/t-sql/queries/output-clause-transact-sql)
or add a `select ID = convert(bigint, SCOPE_IDENTITY());` to the end of your
query (ref [SCOPE_IDENTITY](https://docs.microsoft.com/en-us/sql/t-sql/functions/scope-identity-transact-sql)).
This will ensure you are getting the correct ID and will prevent a network round trip.
* [NewConnector](https://godoc.org/github.com/denisenkom/go-mssqldb#NewConnector)
may be used with [OpenDB](https://golang.org/pkg/database/sql/#OpenDB).
* [Connector.SessionInitSQL](https://godoc.org/github.com/denisenkom/go-mssqldb#Connector.SessionInitSQL)
may be set to set any driver specific session settings after the session
has been reset. If empty the session will still be reset but use the database
defaults in Go1.10+.
## Features
* Can be used with SQL Server 2005 or newer
* Can be used with Microsoft Azure SQL Database
* Can be used on all go supported platforms (e.g. Linux, Mac OS X and Windows)
* Supports new date/time types: date, time, datetime2, datetimeoffset
* Supports string parameters longer than 8000 characters
* Supports encryption using SSL/TLS
* Supports SQL Server and Windows Authentication
* Supports Single-Sign-On on Windows
* Supports connections to AlwaysOn Availability Group listeners, including re-direction to read-only replicas.
* Supports query notifications
## Tests
`go test` is used for testing. A running instance of MSSQL server is required.
Environment variables are used to pass login information.
Example:
env SQLSERVER_DSN=sqlserver://user:pass@hostname/instance?database=test1 go test
## Deprecated
These features still exist in the driver, but they are are deprecated.
### Query Parameter Token Replace (driver "mssql")
If you use the driver name "mssql" (rather then "sqlserver") the SQL text
will be loosly parsed and an attempt to extract identifiers using one of
* ?
* ?nnn
* :nnn
* $nnn
will be used. This is not recommended with SQL Server.
There is at least one existing `won't fix` issue with the query parsing.
Use the native "@Name" parameters instead with the "sqlserver" driver name.
## Known Issues
* SQL Server 2008 and 2008 R2 engine cannot handle login records when SSL encryption is not disabled.
To fix SQL Server 2008 R2 issue, install SQL Server 2008 R2 Service Pack 2.
To fix SQL Server 2008 issue, install Microsoft SQL Server 2008 Service Pack 3 and Cumulative update package 3 for SQL Server 2008 SP3.

## Version 1.1 (2013-11-02)
Changes:
- Go-MySQL-Driver now requires Go 1.1
- Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
- Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
- `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
- DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
- Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
- Optimized the buffer for reading
- stmt.Query now caches column metadata
- New Logo
- Changed the copyright header to include all contributors
- Improved the LOAD INFILE documentation
- The driver struct is now exported to make the driver directly accessible
- Refactored the driver tests
- Added more benchmarks and moved all to a separate file
- Other small refactoring
New Features:
- Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
- Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
- Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
Bugfixes:
- Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
- Convert to DB timezone when inserting `time.Time`
- Splitted packets (more than 16MB) are now merged correctly
- Fixed false positive `io.EOF` errors when the data was fully read
- Avoid panics on reuse of closed connections
- Fixed empty string producing false nil values
- Fixed sign byte for positive TIME fields

Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.

---------------------------------------
## Installation
Simple install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
```bash
$ go get -u github.com/go-sql-driver/mysql
```
Make sure [Git is installed](https://git-scm.com/downloads) on your machine and in your system's `PATH`.
## Usage
_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.
Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`:
```go
import "database/sql"
import _ "github.com/go-sql-driver/mysql"
db, err := sql.Open("mysql", "user:password@/dbname")
```
[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
### DSN (Data Source Name)
The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
```
[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
```
A DSN in its fullest form:
```
username:password@protocol(address)/dbname?param=value
```
Except for the databasename, all values are optional. So the minimal DSN is:
```
/dbname
```
If you do not want to preselect a database, leave `dbname` empty:
```
/
```
This has the same effect as an empty DSN string:
```
```
Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.
#### Password
Passwords can consist of any character. Escaping is **not** necessary.
#### Protocol
See [net.Dial](https://golang.org/pkg/net/#Dial) for more information which networks are available.
In general you should use an Unix domain socket if available and TCP otherwise for best performance.
#### Address
For TCP and UDP networks, addresses have the form `host[:port]`.
If `port` is omitted, the default port will be used.
If `host` is a literal IPv6 address, it must be enclosed in square brackets.
The functions [net.JoinHostPort](https://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](https://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
#### Parameters
*Parameters are case-sensitive!*
Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
##### `allowAllFiles`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files.
[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
##### `allowCleartextPasswords`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
##### `allowNativePasswords`
```
Type: bool
Valid Values: true, false
Default: true
```
`allowNativePasswords=false` disallows the usage of MySQL native password method.
##### `allowOldPasswords`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
##### `charset`
```
Type: string
Valid Values: <name>
Default: none
```
Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
Unless you need the fallback behavior, please use `collation` instead.
##### `checkConnLiveness`
```
Type: bool
Valid Values: true, false
Default: true
```
On supported platforms connections retrieved from the connection pool are checked for liveness before using them. If the check fails, the respective connection is marked as bad and the query retried with another connection.
`checkConnLiveness=false` disables this liveness check of connections.
##### `collation`
```
Type: string
Valid Values: <name>
Default: utf8mb4_general_ci
```
Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5. You should use an older collation (e.g. `utf8_general_ci`) for older MySQL.
Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)).
##### `clientFoundRows`
```
Type: bool
Valid Values: true, false
Default: false
```
`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
##### `columnsWithAlias`
```
Type: bool
Valid Values: true, false
Default: false
```
When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
```
SELECT u.id FROM users as u
```
will return `u.id` instead of just `id` if `columnsWithAlias=true`.
##### `interpolateParams`
```
Type: bool
Valid Values: true, false
Default: false
```
If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
##### `loc`
```
Type: string
Valid Values: <escaped name>
Default: UTC
```
Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details.
Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
##### `maxAllowedPacket`
```
Type: decimal number
Default: 4194304
```
Max packet size allowed in bytes. The default value is 4 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*.
##### `multiStatements`
```
Type: bool
Valid Values: true, false
Default: false
```
Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
When `multiStatements` is used, `?` parameters must only be used in the first statement.
##### `parseTime`
```
Type: bool
Valid Values: true, false
Default: false
```
`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`.
##### `readTimeout`
```
Type: duration
Default: 0
```
I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
##### `rejectReadOnly`
```
Type: bool
Valid Values: true, false
Default: false
```
`rejectReadOnly=true` causes the driver to reject read-only connections. This
is for a possible race condition during an automatic failover, where the mysql
client gets connected to a read-only replica after the failover.
Note that this should be a fairly rare case, as an automatic failover normally
happens when the primary is down, and the race condition shouldn't happen
unless it comes back up online as soon as the failover is kicked off. On the
other hand, when this happens, a MySQL application can get stuck on a
read-only connection until restarted. It is however fairly easy to reproduce,
for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
If you are not relying on read-only transactions to reject writes that aren't
supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
is safer for failovers.
Note that ERROR 1290 can be returned for a `read-only` server and this option will
cause a retry for that error. However the same error number is used for some
other cases. You should ensure your application will never cause an ERROR 1290
except for `read-only` mode when enabling this option.
##### `serverPubKey`
```
Type: string
Valid Values: <name>
Default: none
```
Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN.
Public keys are used to transmit encrypted data, e.g. for authentication.
If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.
##### `timeout`
```
Type: duration
Default: OS default
```
Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
##### `tls`
```
Type: bool / string
Valid Values: true, false, skip-verify, preferred, <name>
Default: false
```
`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side) or use `preferred` to use TLS only when advertised by the server. This is similar to `skip-verify`, but additionally allows a fallback to a connection which is not encrypted. Neither `skip-verify` nor `preferred` add any reliable security. You can use a custom TLS config after registering it with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
##### `writeTimeout`
```
Type: duration
Default: 0
```
I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
##### System Variables
Any other parameters are interpreted as system variables:
* `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
* `<enum_var>=<value>`: `SET <enum_var>=<value>`
* `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
Rules:
* The values for string variables must be quoted with `'`.
* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
(which implies values of string variables must be wrapped with `%27`).
Examples:
* `autocommit=1`: `SET autocommit=1`
* [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
* [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'`
#### Examples
```
user@unix(/path/to/socket)/dbname
```
```
root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
```
```
user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
```
Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html):
```
user:password@/dbname?sql_mode=TRADITIONAL
```
TCP via IPv6:
```
user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
```
TCP on a remote host, e.g. Amazon RDS:
```
id:password@tcp(your-amazonaws-uri.com:3306)/dbname
```
Google Cloud SQL on App Engine:
```
user:password@unix(/cloudsql/project-id:region-name:instance-name)/dbname
```
TCP using default port (3306) on localhost:
```
user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
```
Use the default protocol (tcp) and host (localhost:3306):
```
user:password@/dbname
```
No Database preselected:
```
user:password@/
```
### Connection pool and timeouts
The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
## `ColumnType` Support
This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
## `context.Context` Support
Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
### `LOAD DATA LOCAL INFILE` support
For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
```go
import "github.com/go-sql-driver/mysql"
```
Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
### `time.Time` support
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical equivalent in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
Alternatively you can use the [`NullTime`](https://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
### Unicode support
Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
See http://dev.mysql.com/doc/refman/8.0/en/charset-unicode.html for more details on MySQL's Unicode support.
## Testing / Development
To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
