mysql子查询不支持limit问题解决

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

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
