sqlx-builder

用于实现sqlx的链式操作

安装

go get github.com/laoqiu/sqlx-builder

初始化

import (
	sqlxb "github.com/laoqiu/sqlx-builder"
)
db, err := sqlxb.Connect()
if err != nil {
	return err
}
// 加载mapper
builder.LoadMapper(db, sqlxb.DefaultMapper)

支持的链式操作

dest := &Person{}
p := map[string]interface{}{
    "phone": "13012345678",
}
debug := true
query = sqlxb.Table("tablename").Join("table2", "table2.id = table1.t_id").
    Where("name like ?", "%name%").
    Where("address = ?", "test").
    Where("phone = :phone", p)
err := sqlxb.New(db, query, debug).First(dest)
if err != nil {
    log.Println(err) 
}

支持的函数及结构体
