Microsoft报表生成器TSQL查询问题

我已经编写了以下TSQL查询，并正在Microsoft Report Builder中运行它。我的问题是一部分工作不正常。任何信息都会非常有用。谢谢

注意-从ufnARCUGetLatestProcessDate中选择ProcessDate返回运行查询的日期。这是我们的标准功能之一。 这是我遇到问题的部分。出于某种原因，它无法找到确实有空结束日期的贷款。例如，我正在测试的帐户有一笔未结贷款，但当我应该收到1时，它返回的值为0。有人看到我可能错过什么了吗

    (SELECT COUNT(*) -- Check if there are no open loans
     FROM arcu.vwARCULoan AS L
     WHERE A.ACCOUNTNUMBER=L.AccountNumber AND
     L.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     L.LoanCloseDate IS NOT NULL)=0 AND -- END Check if there are no open loans

下面是整个查询

SELECT
   A.ACCOUNTNUMBER AS 'Account Number'
  ,A.AccountBranch AS 'Branch Number'
  ,A.AccountOpenDate AS 'Account Open Date'
  ,A.AccountActivityDate AS 'Last Activity Date'
  ,N.NameFirst+' '+N.NameLast AS 'Member Name'
FROM
  arcu.vwARCUAccount AS A
LEFT OUTER JOIN arcu.vwARCUName AS N
ON A.ACCOUNTNUMBER = N.AccountNumber
WHERE
  A.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
  A.AccountCloseDate IS NULL AND
  A.AccountOpenDate>DATEADD(DAY,-30,A.AccountOpenDate) AND
  N.NameType=0 AND
  N.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
    (SELECT SUM(S.ShareBalance) -- Check if all shares are zero
     FROM arcu.vwARCUShare AS S
     WHERE A.ACCOUNTNUMBER=S.AccountNumber AND
     S.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     A.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()))=0 AND -- END Check if all shares are zero
    (SELECT COUNT(*) -- Check if there are no open loans
     FROM arcu.vwARCULoan AS L
     WHERE A.ACCOUNTNUMBER=L.AccountNumber AND
     L.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     A.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     L.LoanCloseDate IS NOT NULL)=0 AND -- END Check if there are no open loans
    (SELECT COUNT(*) --Check if tracking records exist 
     FROM arcu.vwARCULoanTracking AS T
     WHERE A.ACCOUNTNUMBER=T.AccountNumber AND 
     T.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND 
     A.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     T.LoanTrackingType IN(@TRACKINGTYPES) )=0 AND --END Check if tracking records exist 
    (SELECT COUNT(*)
     FROM arcu.vwARCUInventory AS I
     WHERE A.ACCOUNTNUMBER=I.InventoryAccountNumber AND
     I.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     A.ProcessDate = (SELECT ProcessDate FROM ufnARCUGetLatestProcessDate()) AND
     I.InventoryStatus=2 AND 
     I.InventoryType IN (@INVENTORYTYPE))=0 
ORDER BY A.ACCOUNTNUMBER

我假设如果贷款仍然有效，那么L.LoanClose将为空

在这种情况下，查询的问题是

 L.LoanCloseDate IS NOT NULL

此标准意味着您只计算已结贷款，即LoanClosedDate中有值的贷款。你似乎需要的是相反的，即开放贷款。因此，您可能只需要将此标准更改为

 L.LoanCloseDate IS NULL

---

因此，您正在计算未结贷款。

您真的应该帮助我们，为您提供更多帮助。你的第一个代码片段是不可理解的，也不能运行，而第二个代码片段是巨大的。请先缩小问题范围，尝试创建一个新的解决方案。此外，如果您告诉我们您试图解决的问题以及遇到的问题，这会有所帮助。顺便说一句，我还将通过声明局部变量@ProcessDate并将其设置为对该函数的一次调用来替换您对ufnARCUGetLatestProcessDate函数的多次调用。然后将对该函数的其他调用替换为@ProcessDate。这将减少查询开销，并使代码更具可读性。
