如何旋转 mySQL Query 中的两列

Question

这个查询差不多了。我现在唯一的问题是结果没有旋转。相反，它们保留在名为 Value 的列中。

SELECT * FROM (
    SELECT
        jD.AccountID, 
        SUM(jD.Amount) AS [Total Dollars], 
        COA.Name as COAName, 
        SUM(jD.Qty) AS QTY, 
        CONVERT(date, GETDATE()) AS Date, 
        AttributeDefinitions.Name, 
        AttributeValues.Value
    FROM
        AttributeDefinitions INNER JOIN
        AttributeCategories ON AttributeDefinitions.AttributeCategoryID = AttributeCategories.AttributeCategoryID INNER JOIN
        AttributeValues ON AttributeDefinitions.AttributeDefinitionID = AttributeValues.AttributeDefinitionID RIGHT OUTER JOIN
        JnlDetails AS jD WITH (NOLOCK) INNER JOIN
        COA ON jD.AccountID = COA.AccountID ON AttributeValues.AttributeValueGroupID = COA.AttributeValueGroupID
    WHERE
        (jD.CreateDate >= GETDATE() - 2) AND 
        (jD.CreateDate < GETDATE() + 1)
    GROUP BY 
        jD.AccountID, 
        COA.Name, 
        jD.Qty, 
        jD.CreateDate, 
        AttributeDefinitions.Name, 
        AttributeValues.Value
   
) as T1
PIVOT
(
   MAX([Name]) FOR Name IN ([ACCT_NO], [DEPT_ID], [GLENTRY_CLASSID],[GLENTRY_PROJECTID]
   ,[GLDIMBENEFITING_DEPARTMENT],[GLDIMFUND],[LOCATION_ID])
) PT

Answer 1

这就是你要找的吗？

SELECT * FROM (
    SELECT
        jD.AccountID, 
        SUM(jD.Amount) AS [Total Dollars], 
        COA.Name, 
        SUM(jD.Qty) AS QTY, 
        CONVERT(date, GETDATE()) AS Date, 
        AttributeDefinitions.Name, 
        AttributeValues.Value
    FROM
        AttributeDefinitions INNER JOIN
        AttributeCategories ON AttributeDefinitions.AttributeCategoryID = AttributeCategories.AttributeCategoryID INNER JOIN
        AttributeValues ON AttributeDefinitions.AttributeDefinitionID = AttributeValues.AttributeDefinitionID RIGHT OUTER JOIN
        JnlDetails AS jD WITH (NOLOCK) INNER JOIN
        COA ON jD.AccountID = COA.AccountID ON AttributeValues.AttributeValueGroupID = COA.AttributeValueGroupID
    WHERE
        (jD.CreateDate >= GETDATE() - 2) AND 
        (jD.CreateDate < GETDATE() + 1)
    GROUP BY 
        jD.AccountID, 
        COA.Name, 
        jD.Qty, 
        jD.CreateDate, 
        AttributeDefinitions.Name, 
        AttributeDefinitions.Description, 
        AttributeValues.Value
    ORDER BY 
        jD.AccountID
) as T1
PIVOT
(
   MAX([Name]) FOR Name IN ([Account Code], [Project Code], [Fund])
) PT

Answer 2

请注意，结果会有所不同，所以我可以有 3 列，或者 4 , 5 等...最多 10 列

那你需要动态SQL

DECLARE @Attributes VARCHAR(MAX), @SQL VARCHAR(MAX)

SELECT @Attributes = STUFF((SELECT ',' + QUOTENAME(Name) 
                    FROM AttributeDefinitions
            FOR XML PATH(''), TYPE
            ).value('.', 'VARCHAR(MAX)') 
        ,1,1,'')

SET @SQL = '
SELECT * FROM (
    SELECT
        jD.AccountID, 
        SUM(jD.Amount) AS [Total Dollars], 
        COA.Name, 
        SUM(jD.Qty) AS QTY, 
        CONVERT(date, GETDATE()) AS Date, 
        AttributeDefinitions.Name, 
        AttributeValues.Value
    FROM
        AttributeDefinitions INNER JOIN
        AttributeCategories ON AttributeDefinitions.AttributeCategoryID = AttributeCategories.AttributeCategoryID INNER JOIN
        AttributeValues ON AttributeDefinitions.AttributeDefinitionID = AttributeValues.AttributeDefinitionID RIGHT OUTER JOIN
        JnlDetails AS jD WITH (NOLOCK) INNER JOIN
        COA ON jD.AccountID = COA.AccountID ON AttributeValues.AttributeValueGroupID = COA.AttributeValueGroupID
    WHERE
        (jD.CreateDate >= GETDATE() - 2) AND 
        (jD.CreateDate < GETDATE() + 1)
    GROUP BY 
        jD.AccountID, 
        COA.Name, 
        jD.Qty, 
        jD.CreateDate, 
        AttributeDefinitions.Name, 
        AttributeDefinitions.Description, 
        AttributeValues.Value
    ORDER BY 
        jD.AccountID
) T
PIVOT
(
   MAX([Name]) FOR Name IN (' + @Attributes + ')
) PT
'

EXEC(@SQL);
