exists附近有错？
select top 16 * from picUploadT where picType= 'baobaoXiu ' and userid in (1,2,3) order by picId desc 这样是不要运行的
select top 16 * from picUploadT where picType= 'baobaoXiu ' and userid exists (1,2,3) order by picId desc 就提示错误。
请问：错在哪里？谢谢
[解决办法]
declare @t table(id int)
insert into @t select 1 union select 2 union select 3 union select 4
select *
from @t
where id =any (select 1 union select 2)
/*
id
-----------
1
2
*/
嘿嘿

select top 16 * from picUploadT where picType= 'baobaoXiu ' and userid exists (1,2,3) order by picId desc
userid exists (1,2,3) 这里不对
exists 和 in不是一个概念
