在我尝试计算每个帐户 (ACCT) 有多少付款 (trans_key) 之前,此查询工作正常。
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'
当弄乱计数聚合函数时,我能够获取一些数据,但不是正确的计数。它只是给了我表格内所有“付款”的计数,而不是每个 ACCT 的金额。
