limit不支援內層巢狀
[select * from c_talk where talk_id in ( select talk_id from c_post group by talk_id order by count(post_id) limit 0,14)]提示limit不支援內層。。。
mysql什麼版本？ 應該支援， 錯誤提示的實際內容是什麼？
到底是不支援limit還是缺少別名？ 加上t再試。
select * from c_talk where talk_id in ( select talk_id from c_post group by talk_id order by count(post_id) limit 0,14) t
select * from c_talk a,(select talk_id,count(*) as pid from c_post group by talk_id)b
where a. talk_id=b.talk_id
order by b.pid
limit 0,14;
select * from c_talk a
inner join
select talk_id from c_post group by talk_id order by count(post_id) limit 0,14) b
on a.talk_id=b.talk_id
