# 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 {
t.Fatalf("an error '%s' was not expected when opening a stub database connection", err)
}
defer db.Close()
mock.ExpectBegin()
mock.ExpectExec("UPDATE products").WillReturnResult(sqlmock.NewResult(1, 1))
mock.ExpectExec("INSERT INTO product_viewers").WithArgs(2, 3).WillReturnResult(sqlmock.NewResult(1, 1))
mock.ExpectCommit()
// now we execute our method
if err = recordStats(db, 2, 3); err != nil {
t.Errorf("error was not expected while updating stats: %s", err)
}
// we make sure that all expectations were met
if err := mock.ExpectationsWereMet(); err != nil {
t.Errorf("there were unfulfilled expectations: %s", err)
}
}
// a failing test case
func TestShouldRollbackStatUpdatesOnFailure(t *testing.T) {
db, mock, err := sqlmock.New()
if err != nil {
t.Fatalf("an error '%s' was not expected when opening a stub database connection", err)
}
defer db.Close()
mock.ExpectBegin()
mock.ExpectExec("UPDATE products").WillReturnResult(sqlmock.NewResult(1, 1))
mock.ExpectExec("INSERT INTO product_viewers").
WithArgs(2, 3).
WillReturnError(fmt.Errorf("some error"))
mock.ExpectRollback()
// now we execute our method
if err = recordStats(db, 2, 3); err == nil {
t.Errorf("was expecting an error, but there was none")
}
// we make sure that all expectations were met
if err := mock.ExpectationsWereMet(); err != nil {
t.Errorf("there were unfulfilled expectations: %s", err)
}
}
```
## 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

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.

# How to Contribute
CoreOS projects are [Apache 2.0 licensed](LICENSE) and accept contributions via
GitHub pull requests. This document outlines some of the conventions on
development workflow, commit message formatting, contact points and other
resources to make it easier to get your contribution accepted.
# Certificate of Origin
By contributing to this project you agree to the Developer Certificate of
Origin (DCO). This document was created by the Linux Kernel community and is a
simple statement that you, as a contributor, have the legal right to make the
contribution. See the [DCO](DCO) file for details.
# Email and Chat
The project currently uses the general CoreOS email list and IRC channel:
- Email: [coreos-dev](https://groups.google.com/forum/#!forum/coreos-dev)
- IRC: #[coreos](irc://irc.freenode.org:6667/#coreos) IRC channel on freenode.org
Please avoid emailing maintainers found in the MAINTAINERS file directly. They
are very busy and read the mailing lists.
## Getting Started
- Fork the repository on GitHub
- Read the [README](README.md) for build and test instructions
- Play with the project, submit bugs, submit patches!
## Contribution Flow
This is a rough outline of what a contributor's workflow looks like:
- Create a topic branch from where you want to base your work (usually master).
- Make commits of logical units.
- Make sure your commit messages are in the proper format (see below).
- Push your changes to a topic branch in your fork of the repository.
- Make sure the tests pass, and add any new tests as appropriate.
- Submit a pull request to the original repository.
Thanks for your contributions!
### Format of the Commit Message
We follow a rough convention for commit messages that is designed to answer two
questions: what changed and why. The subject line should feature the what and
the body of the commit should describe the why.
```
scripts: add the test-cluster command
this uses tmux to setup a test cluster that you can easily kill and
start for debugging.
Fixes #38
```
The format can be described more formally as follows:
```
<subsystem>: <what changed>
<BLANK LINE>
<why this change was made>
<BLANK LINE>
<footer>
```
The first line is the subject and should be no longer than 70 characters, the
second line is always blank, and other lines should be wrapped at 80 characters.
This allows the message to be easier to read on GitHub as well as in various
git tools.

[![Build Status](https://travis-ci.org/coreos/go-oidc.png?branch=master)](https://travis-ci.org/coreos/go-oidc)
## OpenID Connect support for Go
This package enables OpenID Connect support for the [golang.org/x/oauth2](https://godoc.org/golang.org/x/oauth2) package.
```go
provider, err := oidc.NewProvider(ctx, "https://accounts.google.com")
if err != nil {
// handle error
}
// Configure an OpenID Connect aware OAuth2 client.
oauth2Config := oauth2.Config{
ClientID: clientID,
ClientSecret: clientSecret,
RedirectURL: redirectURL,
// Discovery returns the OAuth2 endpoints.
Endpoint: provider.Endpoint(),
// "openid" is a required scope for OpenID Connect flows.
Scopes: []string{oidc.ScopeOpenID, "profile", "email"},
}
```
OAuth2 redirects are unchanged.
```go
func handleRedirect(w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, oauth2Config.AuthCodeURL(state), http.StatusFound)
}
```
The on responses, the provider can be used to verify ID Tokens.
```go
var verifier = provider.Verifier(&oidc.Config{ClientID: clientID})
func handleOAuth2Callback(w http.ResponseWriter, r *http.Request) {
// Verify state and errors.
oauth2Token, err := oauth2Config.Exchange(ctx, r.URL.Query().Get("code"))
if err != nil {
// handle error
}
// Extract the ID Token from OAuth2 token.
rawIDToken, ok := oauth2Token.Extra("id_token").(string)
if !ok {
// handle missing token
}
// Parse and verify ID Token payload.
idToken, err := verifier.Verify(ctx, rawIDToken)
if err != nil {
// handle error
}
// Extract custom claims
var claims struct {
Email string `json:"email"`
Verified bool `json:"email_verified"`
}
if err := idToken.Claims(&claims); err != nil {
// handle error
}
}
```

# 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 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)
```
## 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
* "cloud.google.com/go/civil".Date -> date
* "cloud.google.com/go/civil".DateTime -> datetime2
* "cloud.google.com/go/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.
