select id,name from user where id=1這個查出來的是id=1的所有項目，現在我把他改成select id,name,fs=(select top 1 nFinalScore from appname where id=u.id order by Date_Time desc),ap=(select top 1 iApproveSign from appname where id=u.id order by Date_Time desc) from user as u where id=1這樣運行，是可以查出FS和AP的值，我想問問把fs的改成這樣(select top 1 nFinalScore，iApproveSign from appname where id=u.id order by Date_Time desc)我應該怎么改，這樣改是錯的
