此查询有一个问题，除了FOR列
它显示了这个库存中的多个值，在相应条件下它应该只显示一个值'7'，这将取决于该值将设置coulmn值，但现在因为它显示所有值，它会导致过多的重复和其他问题这里是查询：

SELECT        T0.ItemCode, T0.ItemName, T0.CardCode, T0.CodeBars, T0.U_VEN_CODE, T2.UgpCode, T3.AltQty, T3.BaseQty, CASE WHEN T4.Uomentry = - 1 THEN T0.[BuyUnitMsr] ELSE t4.UomName END AS 'UoMName', 
                         T4.UomEntry, T0.U_CAT_CODE, T0.U_CAT_NAME, T1.CardName,
                             (SELECT        TOP (1) PDN1.U_AC_QTY_ORDER
                               FROM            PDN1 INNER JOIN
                                                         OPDN ON PDN1.DocEntry = OPDN.DocEntry
                               WHERE        (PDN1.ItemCode = T0.ItemCode) AND (OPDN.CardCode = T0.CardCode)

FROM            OITM AS T0 INNER JOIN
                         OCRD AS T1 ON T0.CardCode = T1.CardCode INNER JOIN
                         OUGP AS T2 ON T0.UgpEntry = T2.UgpEntry INNER JOIN
                         UGP1 AS T3 ON T2.UgpEntry = T3.UgpEntry INNER JOIN
                         OITW AS SMMU01 ON T0.ItemCode = SMMU01.ItemCode INNER JOIN
                         OITW AS SMAB01 ON SMMU01.ItemCode = SMAB01.ItemCode INNER JOIN
                         OITW AS SMKH01 ON SMAB01.ItemCode = SMKH01.ItemCode INNER JOIN
                         ITM9 ON T0.ItemCode = ITM9.ItemCode AND ITM9.PriceList = '7' INNER JOIN
                         ITM1 ON T0.ItemCode = ITM1.ItemCode LEFT OUTER JOIN
                         ITM1 AS ITM1_1 ON T0.ItemCode = ITM1_1.ItemCode AND ITM1_1.PriceList = '10' LEFT OUTER JOIN
                         OUOM AS T4 ON T3.UomEntry = T4.UomEntry
WHERE        (T0.Series = '65') AND (T4.UomEntry = 3 OR
                         T4.UomEntry = '-1') AND (SMMU01.WhsCode = 'W-SMMU01') AND (SMAB01.WhsCode = 'W-SMAB01') AND (SMKH01.WhsCode = 'W-SMKH01')

这是coulmn的结果

如何才能让条件中只显示“7”？ THX

Answer 1

SELECT  [...]
    , ITM1.PriceList AS Expr6
    , ITM1.Price AS Expr7
FROM   
    OITM AS T0 
    INNER JOIN OCRD AS T1 
        ON T0.CardCode = T1.CardCode 
    INNER JOIN OUGP AS T2 
        ON T0.UgpEntry = T2.UgpEntry 
    INNER JOIN UGP1 AS T3 
        ON T2.UgpEntry = T3.UgpEntry 
    INNER JOIN OITW AS SMMU01 
        ON T0.ItemCode = SMMU01.ItemCode 
    INNER JOIN OITW AS SMAB01 
        ON SMMU01.ItemCode = SMAB01.ItemCode 
    INNER JOIN OITW AS SMKH01 
        ON SMAB01.ItemCode = SMKH01.ItemCode 
    INNER JOIN ITM9 
        ON T0.ItemCode = ITM9.ItemCode 
        AND ITM9.PriceList = '7' 
    INNER JOIN ITM1 
        ON T0.ItemCode = ITM1.ItemCode 
    LEFT OUTER JOIN ITM1 AS ITM1_1 
        ON T0.ItemCode = ITM1_1.ItemCode 
        AND ITM1_1.PriceList = '10' 
    LEFT OUTER JOIN OUOM AS T4 
        ON T3.UomEntry = T4.UomEntry

您的INNER JOIN ITM1没有PriceList = '7'过滤器

您应该可以通过以下方式修复它：

INNER JOIN ITM1 
    ON T0.ItemCode = ITM1.ItemCode 
    AND ITM1.PriceList = '7'

现在的问题是：ITM1和ITM9为何重复？
