sql做连续减法怎么办？

SQL code

(isnull((select sum(cq_dinner) from cjf_card_dzcq where cq_cardno=a.c_incode and cq_type='04' and cq_ctime<=:etime),0) -
isnull((select sum(cq_dinner) from cjf_card_dzcq where cq_cardno=a.c_incode and cq_type='03' and cq_ctime<=:etime),0) ) as totaldinner

//通过
(isnull((select sum(cq_dinner) from cjf_card_dzcq where cq_cardno=a.c_incode and cq_type='04' and cq_ctime<=:etime),0) -
isnull((select sum(cq_dinner) from cjf_card_dzcq where cq_cardno=a.c_incode and cq_type='05' and cq_ctime<=:etime),0) -
isnull((select sum(cq_dinner) from cjf_card_dzcq where cq_cardno=a.c_incode and cq_type='03' and cq_ctime<=:etime),0) ) as totaldinner-
//通不过

------解决方案--------------------
你的第二段Code， as totaldinner 后多了一个减号，去掉再试试。
