> `orderby`用于排序查询的结果顺序,需要为一个字符串 > 例子: ```php //使用id降序排列 Db('user')->select([ 'orderby' => 'id desc', ])->get(); //sql:SELECT * FROM `user` ORDER BY id desc; //按照姓名升序排列,兼容utf8 Db('user')->select([ 'orderby' => 'convert(username using gbk) asc', ])->get(); //sql:SELECT * FROM `user` ORDER BY convert(username using gbk) asc; //按照年龄字段升序,并使用id降序 Db('user')->select([ 'orderby' => 'age asc,id desc', ])->get(); //sql:SELECT * FROM `user` ORDER BY age asc,id desc; ``` >SQL小常识:在SQL语句中,`ASC`为升序,`DESC`为降序哟~
