thinkphp3 联表查询

Question

取出一个表中满足状态值=2的几条数据，再用几条数据的id查其他表

用thinkphp该怎么做啊

不是很会联表查询

select * from re_deposit where deposit_status = 2

select * from re_client INNER JOIN re_deposit on re_deposit.client_code = re_client.client_code

代言 · Answer

select * from re_client INNER JOIN re_deposit on re_deposit.client_code = re_client.client_code
 where re_deposit.deposit_status = 2

*注意，假如两个表有字段相同，会出现字段只取其中一个表，所以建议对字添加前缀

//tp3大概是这样写

M("re_client")->join("re_deposit on re_deposit.client_code = re_client.client_code","INNER JOIN")->where("re_deposit.deposit_status = 2")->select();
