在我尝试获取针对每个帐户(ACCT)的付款数量(trans_key)之前,此查询正常运行。
无法对包含聚合或子查询的表达式执行聚合函数。
SELECT CONVERT(VARCHAR,D.ACCT) ClientReference,
ISNULL((SELECT S.SD_DATA
FROM SDDATA AS S
WHERE S.DEBT_KEY=D.DEBT_KEY AND S.SD_KEY=36),' ') Division,
REPLACE(RTRIM(DB.FNAME)+' '+RTRIM(DB.LNAME),',',' ') AccountHolder,
CONVERT(VARCHAR,D.DOR,101) ListedDate,
ISNULL((SELECT SA.SD_DATA
FROM SDDATA AS SA
WHERE SA.DEBT_KEY=D.DEBT_KEY
AND SA.SD_KEY=2),' ') AssignmentType,
CONVERT(VARCHAR,D.BAL) CurrentBalance,
CONVERT(VARCHAR,D.ASSIGNED) PlacementBalance,
CONVERT(VARCHAR,isnull((SELECT -1*SUM(TD.DIST_AMT)
FROM TRANSDIST AS TD,TRANS AS T,TRANS_CODE AS TC
WHERE T.DEBT_KEY=D.DEBT_KEY
AND TD.TRANS_KEY=T.TRANS_KEY
AND TC.TRANS_CODE=T.TRANS_CODE
AND TC.TRANS_BILL=1),0)) AmountRecovered,
CONVERT(VARCHAR,isnull((SELECT (-1*SUM(TD.DIST_AMT)+SUM(DIST_NET))
FROM TRANSDIST AS TD,TRANS AS T,TRANS_CODE AS TC
WHERE T.DEBT_KEY=D.DEBT_KEY
AND TD.TRANS_KEY=T.TRANS_KEY
AND TC.TRANS_CODE=T.TRANS_CODE
AND TC.TRANS_BILL=1),0)) AmountApplied,
CONVERT(VARCHAR,isnull((SELECT (-1*SUM(DIST_NET))
FROM TRANSDIST AS TD,TRANS AS T,TRANS_CODE AS TC
WHERE T.DEBT_KEY=D.DEBT_KEY
AND TD.TRANS_KEY=T.TRANS_KEY
AND TC.TRANS_CODE=T.TRANS_CODE
AND TC.TRANS_BILL=1),0)) SMAFees,
COUNT((select trans_key from trans)) as Payments
FROM DEBT AS D,DEBTOR AS DB,STATUS AS ST
WHERE ST.STAT_KEY=D.STAT_KEY
AND DB.DEBTOR_KEY=D.DEBTOR_KEY
AND D.CLIENT_KEY =43
AND ST.CATEGORY='A'
当搞乱计数聚合函数时,我能够获取soem数据,但不能获取正确的计数。它只是给了我表中所有“付款”的数量而不是每个ACCT的金额。

我觉得您的查询是以一种非常奇怪的方式编写的,这将使调试变得困难。一些想法:
如果可能,请在select语句中使用子查询停止。例如:
ISNULL((选择SA.SD_DATA 来自SDDATA AS SA 在哪里SA.DEBT_KEY = D.DEBT_KEY AND SA.SD_KEY = 2),'')AssignmentType,
可以转换为
ISNULL(SA.SD_DATA,' ')
...
...
FROM DEBT AS D
LEFT JOIN SDDATA AS SA
ON sa.DEBT_KEY = d.DEBT_KEY
停止使用隐含联接
阅读GROUP BY如何使用聚合函数。
这不是解决您确切问题的方法,但如果您想解决此问题,则需要将此查询置于可行状态并进行一些基础研究。
