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:

  • 停止转换您选择的所有内容(至少在您获得之前) 你想要的结果)。这将使您的代码更简洁 更容易调试
  • 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。
