# A pure Go MSSQL driver for Go's database/sql package
|
||||
|
||||
[](https://pkg.go.dev/github.com/denisenkom/go-mssqldb)
|
||||
[](https://ci.appveyor.com/project/denisenkom/go-mssqldb)
|
||||
[](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¶m2=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. The user domain sensitive to the case which is defined in the connection string.
|
||||
* `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¶m2=value`
|
||||
* `sqlserver://username:password@host:port?param1=value¶m2=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`
|
||||
|
||||
ADO strings support synonyms for database, app name, user id, and server
|
||||
* server <= addr, address, network address, data source
|
||||
* user id <= user, uid
|
||||
* database <= initial catalog
|
||||
* app name <= application name
|
||||
|
||||
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"
|
||||
|
||||
### Azure Active Directory authentication
|
||||
|
||||
Azure Active Directory authentication uses temporary authentication tokens to authenticate.
|
||||
The `mssql` package does not provide an implementation to obtain tokens: instead, import the `azuread` package and use driver name `azuresql`. This driver uses [azidentity](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity#section-readme) to acquire tokens using a variety of credential types.
|
||||
|
||||
The credential type is determined by the new `fedauth` connection string parameter.
|
||||
|
||||
* `fedauth=ActiveDirectoryServicePrincipal` or `fedauth=ActiveDirectoryApplication` - authenticates using an Azure Active Directory application client ID and client secret or certificate. Implemented using [ClientSecretCredential or CertificateCredential](https://github.com/Azure/azure-sdk-for-go/tree/main/sdk/azidentity#authenticating-service-principals)
|
||||
* `clientcertpath=<path to certificate file>;password=<certificate password>` or
|
||||
* `password=<client secret>`
|
||||
* `user id=<application id>[@tenantid]` Note the `@tenantid` component can be omitted if the server's tenant is the same as the application's tenant.
|
||||
* `fedauth=ActiveDirectoryPassword` - authenticates using a user name and password.
|
||||
* `user id=username@domain`
|
||||
* `password=<password>`
|
||||
* `applicationclientid=<application id>` - This guid identifies an Azure Active Directory enterprise application that the AAD admin has approved for accessing Azure SQL database resources in the tenant. This driver does not have an associated application id of its own.
|
||||
* `fedauth=ActiveDirectoryDefault` - authenticates using a chained set of credentials. The chain is built from EnvironmentCredential -> ManagedIdentityCredential->AzureCLICredential. See [DefaultAzureCredential docs](https://github.com/Azure/azure-sdk-for-go/wiki/Set-up-Your-Environment-for-Authentication#configure-defaultazurecredential) for instructions on setting up your host environment to use it. Using this option allows you to have the same connection string in a service deployment as on your interactive development machine.
|
||||
* `fedauth=ActiveDirectoryManagedIdentity` or `fedauth=ActiveDirectoryMSI` - authenticates using a system-assigned or user-assigned Azure Managed Identity.
|
||||
* `user id=<identity id>` - optional id of user-assigned managed identity. If empty, system-assigned managed identity is used.
|
||||
* `fedauth=ActiveDirectoryInteractive` - authenticates using credentials acquired from an external web browser. Only suitable for use with human interaction.
|
||||
* `applicationclientid=<application id>` - This guid identifies an Azure Active Directory enterprise application that the AAD admin has approved for accessing Azure SQL database resources in the tenant. This driver does not have an associated application id of its own.
|
||||
|
||||
```go
|
||||
|
||||
import (
|
||||
"database/sql"
|
||||
"net/url"
|
||||
|
||||
// Import the Azure AD driver module (also imports the regular driver package)
|
||||
"github.com/denisenkom/go-mssqldb/azuread"
|
||||
)
|
||||
|
||||
func ConnectWithMSI() (*sql.DB, error) {
|
||||
return sql.Open(azuread.DriverName, "sqlserver://azuresql.database.windows.net?database=yourdb&fedauth=ActiveDirectoryMSI")
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
## 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:
|
||||
|
||||
```go
|
||||
|
||||
var rs mssql.ReturnStatus
|
||||
_, err := db.ExecContext(ctx, "theproc", &rs)
|
||||
log.Printf("status=%d", rs)
|
||||
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```go
|
||||
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:
|
||||
|
||||
```bash
|
||||
env SQLSERVER_DSN=sqlserver://user:pass@hostname/instance?database=test1 go test
|
||||
```
|
||||
|
||||
`AZURESERVER_DSN` environment variable provides the connection string for Azure Active Directory-based authentication. If it's not set the AAD test will be skipped.
|
||||
|
||||
## 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.

# go-sqlite
|
||||
This is a pure-Go SQLite driver for Golang's native [database/sql](https://pkg.go.dev/database/sql) package.
|
||||
The driver has [Go-based implementation of SQLite](https://gitlab.com/cznic/sqlite) embedded in itself (so, you don't need to install SQLite separately)
|
||||
|
||||
# Usage
|
||||
|
||||
## Example
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"database/sql"
|
||||
"log"
|
||||
|
||||
_ "github.com/glebarez/go-sqlite"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// connect
|
||||
db, err := sql.Open("sqlite", ":memory:")
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
// get SQLite version
|
||||
_ := db.QueryRow("select sqlite_version()")
|
||||
}
|
||||
```
|
||||
|
||||
## Connection string examples
|
||||
- in-memory SQLite: ```":memory:"```
|
||||
- on-disk SQLite: ```"path/to/some.db"```
|
||||
- Foreign-key constraint activation: ```":memory:?_pragma=foreign_keys(1)"```
|
||||
|
||||
## Settings PRAGMAs in connection string
|
||||
Any SQLIte pragma can be preset for a Database connection using ```_pragma``` query parameter. Examples:
|
||||
- [journal mode](https://www.sqlite.org/pragma.html#pragma_journal_mode): ```path/to/some.db?_pragma=journal_mode(WAL)```
|
||||
- [busy timeout](https://www.sqlite.org/pragma.html#pragma_busy_timeout): ```:memory:?_pragma=busy_timeout(5000)```
|
||||
|
||||
Multiple PRAGMAs can be specified, e.g.:<br>
|
||||
```path/to/some.db?_pragma=busy_timeout(5000)&_pragma=journal_mode(WAL)```

SQLite Is Public Domain
|
||||
|
||||
All of the code and documentation in SQLite has been dedicated to the public
|
||||
domain by the authors. All code authors, and representatives of the companies
|
||||
they work for, have signed affidavits dedicating their contributions to the
|
||||
public domain and originals of those signed affidavits are stored in a firesafe
|
||||
at the main offices of Hwaci. Anyone is free to copy, modify, publish, use,
|
||||
compile, sell, or distribute the original SQLite code, either in source code
|
||||
form or as a compiled binary, for any purpose, commercial or non-commercial,
|
||||
and by any means.
|
||||
|
||||
The previous paragraph applies to the deliverable code and documentation in
|
||||
SQLite - those parts of the SQLite library that you actually bundle and ship
|
||||
with a larger application. Some scripts used as part of the build process (for
|
||||
example the "configure" scripts generated by autoconf) might fall under other
|
||||
open-source licenses. Nothing from these build scripts ever reaches the final
|
||||
deliverable SQLite library, however, and so the licenses associated with those
|
||||
scripts should not be a factor in assessing your rights to copy and use the
|
||||
SQLite library.
|
||||
|
||||
All of the deliverable code in SQLite has been written from scratch. No code
|
||||
has been taken from other projects or from the open internet. Every line of
|
||||
code can be traced back to its original author, and all of those authors have
|
||||
public domain dedications on file. So the SQLite code base is clean and is
|
||||
uncontaminated with licensed code from other projects.

# Pure-Go SQLite driver for GORM
|
||||
Pure-go (without cgo) implementation of SQLite driver for [GORM](https://gorm.io/)<br><br>
|
||||
This driver has SQLite embedded, you don't need to install one separately.
|
||||
|
||||
# Usage
|
||||
|
||||
```go
|
||||
import (
|
||||
"github.com/glebarez/sqlite"
|
||||
"gorm.io/gorm"
|
||||
)
|
||||
|
||||
db, err := gorm.Open(sqlite.Open("sqlite.db"), &gorm.Config{})
|
||||
```
|
||||
|
||||
### In-memory DB example
|
||||
```go
|
||||
db, err := gorm.Open(sqlite.Open(":memory:"), &gorm.Config{})
|
||||
```
|
||||
|
||||
### Foreign-key constraint activation
|
||||
Foreign-key constraint is disabled by default in SQLite. To activate it, use connection URL parameter:
|
||||
```go
|
||||
db, err := gorm.Open(sqlite.Open(":memory:?_pragma=foreign_keys(1)"), &gorm.Config{})
|
||||
```
|
||||
More info: [https://www.sqlite.org/foreignkeys.html](https://www.sqlite.org/foreignkeys.html)
|
||||
|
||||
# FAQ
|
||||
## How is this better than standard GORM SQLite driver?
|
||||
The [standard GORM driver for SQLite](https://github.com/go-gorm/sqlite) has one major drawback: it is based on a [Go-bindings of SQLite C-source](https://github.com/mattn/go-sqlite3) (this is called [cgo](https://go.dev/blog/cgo)). This fact imposes following restrictions on Go developers:
|
||||
- to build and run your code, you will need a C compiler installed on a machine
|
||||
- SQLite has many features that need to be enabled at compile time (e.g. [json support](https://www.sqlite.org/json1.html)). If you plan to use those, you will have to include proper build tags for every ```go``` command to work properly (```go run```, ```go test```, etc.).
|
||||
- Because of C-compiler requirement, you can't build your Go code inside tiny stripped containers like (golang-alpine)
|
||||
- Building on GCP is not possible because Google Cloud Platform does not allow gcc to be executed.
|
||||
|
||||
**Instead**, this driver is based on pure-Go implementation of SQLite (https://gitlab.com/cznic/sqlite), which is basically an original SQLite C-source AST, translated into Go! So, you may be sure you're using the original SQLite implementation under the hood.
|
||||
|
||||
## Is this tested good ?
|
||||
Yes, The CI pipeline of this driver employs [whole test base](https://github.com/go-gorm/gorm/tree/master/tests) of GORM, which includes more than **12k** tests (see badge on the page-top). Testing is run against latest major releases of Go:
|
||||
- 1.16
|
||||
- 1.17
|
||||
- 1.18
|
||||
|
||||
In following environments:
|
||||
- Linux
|
||||
- Windows
|
||||
- MacOS
|
||||
|
||||
## Is it fast?
|
||||
Well, it's slower than CGo implementation, but not terribly. See the [bechmark of underlying pure-Go driver vs CGo implementation](https://github.com/glebarez/go-sqlite/tree/master/benchmark).
|
||||
|
||||
## Included features
|
||||
- JSON1 (https://www.sqlite.org/json1.html)
|
||||
- Math functions (https://www.sqlite.org/lang_mathfunc.html)

|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including

|
||||
this License, each Contributor hereby grants to You a perpetual,

|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following

||||
boilerplate notice, with the fields enclosed by brackets "[]"
|

Civil provides Date, Time of Day, and DateTime data types.
|

While there are many uses, using specific types when working

with databases make is conceptually eaiser to understand what value

is set in the remote system.
