select * from (select * from city where names like '%xxx%' limit 10) where names like '$xxx%' order by names
错误提示：Every derived table must have its own alias
应该怎么改呀？
------解决方案--------------------
select * from (select * from city where names like '%xxx%' limit 10) where names like '$xxx%' order by names
分析下：
select * from (table)这个table要是一个表
select * from city where names like '%xxx%' limit 10这个很明显不符合，差了很远
所以你那句很明显是错误的
------解决方案--------------------
我没去验证()里面放limit可不可以哈 但根据错误提示应该是这个意思
select * from (select * from city where names like '%xxx%' limit 10) t where names like '$xxx%' order by names
