now, beta, unstable, may be changing some api make your app build failed. now, beta, unstable, may be changing some api make your app build failed.
**Driver Support:**
* MySQL: [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql)
**Features:**
...
**Install:**
go get github.com/astaxie/beego/orm
## Quick Start
#### Simple Usage
```go
package main
import (
"fmt"
"github.com/astaxie/beego/orm"
_ "github.com/go-sql-driver/mysql" // import your used driver
)
// Model Struct
type User struct {
Id int `orm:"auto"`
Name string `orm:"size(100)"`
orm.Manager
}
func init() {
// register model
orm.RegisterModel(new(User))
// set default database
orm.RegisterDataBase("default", "mysql", "root:root@/my_db?charset=utf8", 30)
}
func main() {
o := orm.NewOrm()
user := User{Name: "slene"}
// insert
id, err := o.Insert(&user)
// update
user.Name = "astaxie"
num, err := o.Update(&user)
// read one
u := User{Id: user.Id}
err = o.Read(&u)
// delete
num, err = o.Delete(&u)
}
```
#### Next with relation
```go
type Post struct {
Id int `orm:"auto"`
Title string `orm:"size(100)"`
User *User `orm:"rel(fk)"`
orm.Manager
}
var posts []*Post
qs := o.QueryTable("post")
num, err := qs.Filter("User__Name", "slene").All(&posts)
```
#### Use Raw sql
```go
var maps []Params
num, err := o.Raw("SELECT id FROM user WHERE name = ?", "slene").Values(&maps)
if num > 0 {
fmt.Println(maps[0]["id"])
}
```
#### Transaction
```go
o.Begin()
...
user := User{Name: "slene"}
id, err := o.Insert(&user)
if err != nil {
o.Commit()
} else {
o.Rollback()
}
```

## beego orm 介绍 ## 文档目录
## 快速入门
```go
package main
import (
"fmt"
"github.com/astaxie/beego/orm"
_ "github.com/go-sql-driver/mysql"
)
// 最简单的两个表的定义
type User struct {
Id int `orm:"auto"`
Name string `orm:"size(100)"`
orm.Manager
}
func init() {
// 将表定义注册到 orm 里
orm.RegisterModel(new(User))
// 链接参数设置
orm.RegisterDataBase("default", "mysql", "root:root@/my_db?charset=utf8", 30)
}
func main() {
o := orm.NewOrm()
user := User{Name: "slene"}
// 创建
id, err := o.Insert(&user)
fmt.Println(id, err)
// 更新
user.Name = "astaxie"
num, err := o.Update(&user)
fmt.Println(num, err)
// 查询单个
u := User{Id: user.Id}
err = o.Read(&u)
fmt.Println(u.Name, err)
// 删除
num, err = o.Delete(&u)
fmt.Println(num, err)
}
