如果sql语句中的子查询包含limit
例如: select * from a where id in (select id from b limit 3)
会报错:This version of MySQL doesn’t yet support ‘LIMIT & IN/ALL/ANY/SOME subquery' #
解决办法:
1、加一层子查询
例如:select * from a where id in (select t.id from (select id from b limit 3 )as t)
2、把限制条件放到from而非where子句中,就不必出现嵌套再嵌套。
例如:select * from (select id from a limit 3) as foo
