# Database drivers

Powerful database drivers for package gdb.

## Installation

Let's take `mysql` for example.

```shell
go get -u github.com/gogf/gf/contrib/drivers/mysql/v2
# Easy to copy
go get -u github.com/gogf/gf/contrib/drivers/clickhouse/v2
go get -u github.com/gogf/gf/contrib/drivers/dm/v2
go get -u github.com/gogf/gf/contrib/drivers/mssql/v2
go get -u github.com/gogf/gf/contrib/drivers/oracle/v2
go get -u github.com/gogf/gf/contrib/drivers/pgsql/v2
go get -u github.com/gogf/gf/contrib/drivers/sqlite/v2
go get -u github.com/gogf/gf/contrib/drivers/sqlitecgo/v2
```

Choose and import the driver to your project:

```go
import _ "github.com/gogf/gf/contrib/drivers/mysql/v2"
```

Commonly imported at top of `main.go`:

```go
package main

import (
	_ "github.com/gogf/gf/contrib/drivers/mysql/v2"

	// Other imported packages.
)

func main() {
	// Main logics.
}
```
