这条sql语句有什么兼容问题吗?
$query = " select * from $member_table me1 left join (select *,max(lead_date) as maxdate from $leada_table group by user_id order by lead_date) temp on (me1.user_id = temp.user_id) where me1.islead = 1 and temp.maxdate <= '$timestamp ' ";


这条sql语句有什么兼容问题吗?
本地测试通过,服务器上出错You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'select *,max(lead_date) as maxdate from haoshutong_leada_cn

本地mysql 4.1.21
服务器 MySQL 4.0.23

------解决方案--------------------
子查询4.0不支持,就是中间那个select
