Question

我写了一个SQL查询但是我收到了这个错误：

Msg 145, Level 15, State 1, Procedure GetClientSpecificCollection, Line 18
ORDER BY items must appear in the select list if SELECT DISTINCT is specified.

我的查询就在这里：

    SELECT DISTINCT CONVERT(VARCHAR(11), CBPD.AddedDate, 106) AS [Date],
                CBD.BillNo                                AS [BillNo],
                CBPD.IsOpening                            AS [Opening],
                CASE
                  WHEN CBPD.PaymentMode = 1 THEN 'Cash Payment'
                  WHEN CBPD.PaymentMode = 2 THEN 'By Cheque, '
                                                 + Cast(CBPD.CheckNo AS VARCHAR(10)) + ', '
                                                 + CBPD.BankName
                  WHEN CBPD.PaymentMode = 3 THEN 'NEFT Payment'
                  WHEN CBPD.PaymentMode = 4 THEN 'Bank Draft'
                  WHEN CBPD.PaymentMode = 5 THEN 'Online Payment'
                  ELSE 'NA'
                END                                       AS [PaymentMode],
                CBPD.PayableAmount                        AS [BillingAmount],
                CBPD.PaymentAmount                        AS [PaymentAmount],
                CBPD.RemainAmount                         AS [BillAmount],
                CBD.RemainAmount                          AS [RemainForNext]
FROM   ClientBillingDetail CBD
       INNER JOIN ClientBillPaymentDetail CBPD
               ON CBD.ClientId = CBPD.ClientId
WHERE  CBD.ClientId = @ClientId
       AND CBD.CompanyNameId = 1
       AND ( IsOpening = 1
              OR IsRemaining = 1 )
ORDER  BY IsOpening DESC,
          CBPD.BillNo,
          CBPD.AddedDate

这是我的整个查询，任何人都可以告诉此查询中的问题以及如何更正此查询。

Answer 1

您可以使用别名而不是使用CBPD.IsOpening;

喜欢这个

ORDER BY        Opening DESC, CBPD.BillNo, CBPD.AddedDate

我认为这解决了问题

Answer 2

该错误是因为您要在CBPD.AddedDate声明中转换SELECT。试试这个查询

SELECT DISTINCT
    CONVERT(varchar(11), CBPD.AddedDate, 106) AS [Date],
    CBPD.BillNo AS [BillNo],
    CBPD.IsOpening AS [Opening],
    CASE
        WHEN CBPD.PaymentMode = 1 THEN 'Cash Payment'
        WHEN CBPD.PaymentMode = 2 THEN 'By Cheque, ' + CAST(CBPD.CheckNo AS varchar(10)) + ', ' + CBPD.BankName
        WHEN CBPD.PaymentMode = 3 THEN 'NEFT Payment'
        WHEN CBPD.PaymentMode = 4 THEN 'Bank Draft'
        WHEN CBPD.PaymentMode = 5 THEN 'Online Payment'
        ELSE 'NA'
    END AS [PaymentMode],
    CBPD.PayableAmount AS [BillingAmount],
    CBPD.PaymentAmount AS [PaymentAmount],
    CBPD.RemainAmount AS [BillAmount],
    CBD.RemainAmount AS [RemainForNext]
FROM ClientBillingDetail CBD
INNER JOIN ClientBillPaymentDetail CBPD
    ON CBD.ClientId = CBPD.ClientId
WHERE CBPD.ClientId = @ClientId
AND CBD.CompanyNameId = 1
AND (CBPD.IsOpening = 1
OR CBPD.IsRemaining = 1)
ORDER BY CBPD.IsOpening DESC,
CBPD.BillNo, 
CONVERT(varchar(11),CBPD.AddedDate, 106)

Answer 3

现在无法测试，但如果您确实需要转换日期，则可能需要执行此操作：

SELECT 
  CONVERT(VARCHAR(11), CBPD.AddedDate, 106) AS [Date],
  [BillNo],
  [Opening],
  [PaymentMode],
  [BillingAmount],
  [PaymentAmount],
  [BillAmount],
  [RemainForNext]
from (
    SELECT DISTINCT CBPD.AddedDate AS [Date],
                CBD.BillNo                                AS [BillNo],
                CBPD.IsOpening                            AS [Opening],
                CASE
                  WHEN CBPD.PaymentMode = 1 THEN 'Cash Payment'
                  WHEN CBPD.PaymentMode = 2 THEN 'By Cheque, '
                                                 + Cast(CBPD.CheckNo AS VARCHAR(10)) + ', '
                                                 + CBPD.BankName
                  WHEN CBPD.PaymentMode = 3 THEN 'NEFT Payment'
                  WHEN CBPD.PaymentMode = 4 THEN 'Bank Draft'
                  WHEN CBPD.PaymentMode = 5 THEN 'Online Payment'
                  ELSE 'NA'
                END                                       AS [PaymentMode],
                CBPD.PayableAmount                        AS [BillingAmount],
                CBPD.PaymentAmount                        AS [PaymentAmount],
                CBPD.RemainAmount                         AS [BillAmount],
                CBD.RemainAmount                          AS [RemainForNext]
FROM   ClientBillingDetail CBD
       INNER JOIN ClientBillPaymentDetail CBPD
               ON CBD.ClientId = CBPD.ClientId
WHERE  CBD.ClientId = @ClientId
       AND CBD.CompanyNameId = 1
       AND ( IsOpening = 1
              OR IsRemaining = 1 )
) X
ORDER  BY X.Opening,
          X.BillNo,
          X.[Date]

这样，您在同一个选择中没有明确的顺序。

如果AddedDate是datetime，则应首先将其转换为日期，以便该distinct能够正常工作。

Answer 4

您必须在select子句中使用别名，如下所示

SELECT DISTINCT CONVERT(VARCHAR(11), CBPD.AddedDate, 106) AS [Date],
            CBD.BillNo                                AS [BillNo],
            CBPD.IsOpening                            AS [Opening],
            CASE
              WHEN CBPD.PaymentMode = 1 THEN 'Cash Payment'
              WHEN CBPD.PaymentMode = 2 THEN 'By Cheque, '
                                             + Cast(CBPD.CheckNo AS VARCHAR(10)) + ', '
                                             + CBPD.BankName
              WHEN CBPD.PaymentMode = 3 THEN 'NEFT Payment'
              WHEN CBPD.PaymentMode = 4 THEN 'Bank Draft'
              WHEN CBPD.PaymentMode = 5 THEN 'Online Payment'
              ELSE 'NA'
            END                                       AS [PaymentMode],
            CBPD.PayableAmount                        AS [BillingAmount],
            CBPD.PaymentAmount                        AS [PaymentAmount],
            CBPD.RemainAmount                         AS [BillAmount],
            CBD.RemainAmount                          AS [RemainForNext]
FROM   ClientBillingDetail CBD
   INNER JOIN ClientBillPaymentDetail CBPD
           ON CBD.ClientId = CBPD.ClientId
WHERE  CBD.ClientId = @ClientId
   AND CBD.CompanyNameId = 1
   AND ( IsOpening = 1
          OR IsRemaining = 1 )
ORDER  BY [Opening] DESC,
      [BillNo],
      [Date]

如果在SQL中指定了SELECT DISTINCT，则ORDER BY项必须出现在选择列表中
