Re: [SQL ] 請問從五個資料表內抓最新的五筆SQL怎麼下
select * from (
(select * from board1 order by posttime limit 5) union
(select * from board2 order by posttime limit 5) union
(select * from board3 order by posttime limit 5) union
(select * from board4 order by posttime limit 5) union
(select * from board5 order by posttime limit 5) union
) AS U order by posttime limit 5;
