3表查询，1：多：多，根据1查多再查多

1个代理人对应多个用户，用户对应多个订单

原生sql语句

1 $result = $users->query("select orderid,money,tid,username,game,type,ordertime
2             from (
3                 (cmf_agent a inner join cmf_q_users b on a.id=b.agent_id)
4                 inner join cmf_orders c on c.userid=b.id
5             )where(
6                 agent_id = $agentid
7             )"
8         );
