## orm
orm包含各種api的操作
## 預覽
```go
package main
import (
"fmt"
"github.com/gohouse/gorose/v2"
_ "github.com/mattn/go-sqlite3"
)
type Users struct {
Uid int64 `gorose:"uid"`
Name string `gorose:"name"`
Age int64 `gorose:"age"`
}
func (u *Users) TableName() string {
return "users"
}
var err error
var engin *gorose.Engin
func init() {
engin, err = gorose.Open(&gorose.Config{Driver: "sqlite3", Dsn: "./db.sqlite"})
}
func DB() gorose.IOrm {
return engin.NewOrm()
}
func main() {
db := DB()
var u []Users
var count int64
count,err = db.Table(&u).Fields("uid").AddFields("name,age").
Where("age",">",0).OrderBy("uid desc").GroupBy("age").
Having("age>15").Limit(10).Offset(1).Count()
db.Select()
fmt.Println(count,err,u)
}
```

溫馨提示, 不要忘了導入對應的驅動, 如 MySQL驅動:
```go
import _ "github.com/go-sql-driver/mysql"
```
