我正在创建一个报告，我需要根据过滤器和这些缩进行的相应采购行显示所有采购缩进。如果根据我的情况没有找到购买行，那么它应该返回 NULL 值。但报告未显示采购行中没有记录的缩进。我要加入 4 张桌子 - INH、INL、PL、PH。查询如下所示。

SELECT
    INH.No_
    ,INH.[Approved Date]
    ,INH.Indentor
    ,INL.No_ AS ItemCode
    ,INL.description
    ,INL.Description2
    ,INL.Req_Quantity
    ,INL.[Unit of Measure]
    ,PL.[Document No_]
    ,PH.[Order Date]
    ,PL.Quantity AS OrderedQuantity
    ,PL.[Quantity Received]
FROM [ICTL | HYDERABAD$Indent Header] AS INH
INNER JOIN [ICTL | HYDERABAD$Indent Line] AS INL ON INH.No_ = INL.[Document No_]
LEFT OUTER JOIN [ICTL | HYDERABAD$Purchase Line] AS PL ON INL.[Document No_] = PL.[Indent No_] AND INL.[Line No_] = PL.[Indent Line No_]
LEFT OUTER JOIN [ICTL | HYDERABAD$Purchase Header] AS PH ON PL.[Document No_] = PH.No_
WHERE (UPPER(INH.Indentor) = UPPER(@Name)
    OR @Name IS NULL)
    AND (INL.No_ <> '')
    AND (INH.[Approved Date] >= @StartDate
    OR @StartDate IS NULL)
    AND (INH.[Approved Date] <= @EndDate
    OR @EndDate IS NULL)
    AND (PL.[Document Type] = 1)
ORDER BY ItemCode

问题是您PL.[Document Type] = 1在查询中。这将自动排除所有没有 PL 记录的行（OUTER JOIN那时你没关系）。

要么你必须PL.[Document Type] IS NULL OR PL.[Document Type] = 1在WHERE子句中做，要么你必须添加 PL.[Document Type] = 1到表的JOIN条件中PL。

可能这对您有帮助-

SELECT
      INH.No_
    , INH.[Approved Date]
    , INH.Indentor
    , INL.No_ AS ItemCode
    , INL.description
    , INL.Description2
    , INL.Req_Quantity
    , INL.[Unit of Measure]
    , PL.[Document No_]
    , PH.[Order Date]
    , PL.Quantity AS OrderedQuantity
    , PL.[Quantity Received]
FROM [ICTL | HYDERABAD$Indent Header] INH
JOIN [ICTL | HYDERABAD$Indent Line] INL ON INH.No_ = INL.[Document No_]
LEFT JOIN [ICTL | HYDERABAD$Purchase Line] PL ON INL.[Document No_] = PL.[Indent No_] AND INL.[Line No_] = PL.[Indent Line No_]
LEFT JOIN [ICTL | HYDERABAD$Purchase Header] PH ON PL.[Document No_] = PH.No_
WHERE UPPER(INH.Indentor) = UPPER(ISNULL(@Name, INH.Indentor))
    AND INL.No_ <> ''
    AND INH.[Approved Date] BETWEEN ISNULL(@StartDate, '19000101') AND ISNULL(@EndDate, '30000101')
    AND ISNULL(PL.[Document Type], 1) = 1
ORDER BY ItemCode
