SQL code
也就是说,userid 会有很多,请问可以精简吗?
select * from article,user where article.userid = '1' and article.userid = user.userid or article.userid = '2' and article.userid = user.userid or article.userid = '3' and article.userid = user.userid or article.userid = '4' and article.userid = user.userid or article.userid = '5' and article.userid = user.userid ORDER BY articleid DESC

lz的or and 在一起是什么逻辑
select * from article,user
where article.userid = user.userid or article.userid in ('1','2','3','4','5')
ORDER BY articleid DESC
这样?
select * from article,user
where article.userid = user.userid or article.userid in ('1','2','3','4','5')
ORDER BY articleid DESC
