GoFrame框架ORM原生方法对象操作开箱体验

// 获取默认配置的数据库对象(配置名称为"default")
db := g.DB()
// 获取配置分组名称为"user"的数据库对象
db := g.DB("user")
// 使用原生单例管理方法获取数据库对象单例
db, err := gdb.Instance()
db, err := gdb.Instance("user")

r, err := db.Insert(ctx, "user", gdb.Map {
    "name": "王中阳",
})

one, err := db.GetOne(ctx, "select * from user limit 10")
one, err := db.GetOne(ctx, "select * from user where id=100")
one, err := db.GetOne(ctx, "select * from user where id=?", 100)
one, err := db.GetOne(ctx, "select * from user where id=?", g.Slice{100})

list, err := db.GetAll(ctx, "select * from user limit 10")
list, err := db.GetAll(ctx, "select * from user where age > ? and name like ?", g.Slice{20, "%金%"})

// db.Update/db.Delete 同理
// UPDATE `user` SET `name`='王中阳' WHERE `id`=10000
