dbquery
腾讯云mariadb一主多从数据库操作
链式查询使用
查询单条记录
map,err := new(Query).Db(dbname).Table(tablename).Where("id=?").Where("name=?").Value(1).Value("test").Find()
查询列表
list,err := new(Query).Db(dbname).Table(tablename).Where("id=?").Where("name=?").Value(1).Value("test").Select()
条件"或"
list,err := new(Query).Db(dbname).Table(tablename).Where("id=?").Where("name=?").WhereOr("mobile=?").Value(1).Value("test").Value("22").Select()
联表查
使用Join
list,err := new(Query).Db(dbname).Table(tablename).Join([]string{jointable,tablename.id=jointable.cid,"LEFT"}).Where("id=?").Where("name=?").Value(1).Value("test").Select()
更新
ret,err := new(Query).Db(dbname).Table(tablename).Data("name=?").Data("depart=?").Value("xxx").Value("test").Update()
插入
ret,err := new(Query).Db(dbname).Table(tablename).Data("name=?").Data("depart=?").Value("xxx").Value("test").Create()
删除
ret,err := new(Query).Db(dbname).Table(tablename).Where("name=?").Where("depart=?").Value("xxx").Value("test").Delete()
