Answer 1

試試這個。

SELECT * FROM (SELECT 
      SUM(Cost) AS Cost, 
      CONVERT(VARCHAR(3), DATENAME(MONTH, DATEADD(MONTH, MONTH(MonthCol), - 1))) MonthCol 
      FROM myTable WHERE YEAR(MonthCol) = 2016 
      GROUP BY MonthCol) AS TP 
    PIVOT (SUM(Cost) FOR MonthCol IN ([Jan], [Feb], [Mar], [Apr], [May], [Jun], [Jul], [Aug], [Sep], [Oct], [Nov], [Dec])) AS PVTTable 

對於動態查詢月份和

年

DECLARE @CurrMonth DATE = GETDATE(); 
    DECLARE @CurrYear NVARCHAR(4) = CAST(YEAR(@CurrMonth) AS NVARCHAR(4)) 
    DECLARE @END_MM INT = MONTH(@CurrMonth) --Current Month 
    DECLARE @START_MM INT = 1 --Start Month of Current Year 

    DECLARE @TB_DATE AS TABLE 
    (
     ID INT IDENTITY(1,1), 
     DATE_LIST VARCHAR(12) 
    ) 
    WHILE @START_MM <= @END_MM 
    BEGIN 
     INSERT INTO @TB_DATE (DATE_LIST) VALUES ('['+CONVERT(VARCHAR(3),DATENAME(MONTH, DATEADD(month, @START_MM-1, CAST(@END_MM AS datetime))))+']') 
     SET @START_MM=@START_MM+1 
    END 

    DECLARE @MM_LIST NVARCHAR(MAX) = (SELECT STUFF((SELECT ',' + DATE_LIST 
         FROM @TB_DATE ORDER BY ID DESC 
         FOR XML PATH('')) ,1,1,'') AS Txt) 

    DECLARE @DynamicPivot AS NVARCHAR(MAX) 
    SET @DynamicPivot = N'SELECT * FROM (SELECT 
     ItemId, 
     ItemName, 
     SUM(TotalCost) AS TotalCost, 
     CONVERT(VARCHAR(3), 
     DATENAME(MONTH, DATEADD(MONTH, MONTH(TransDate), - 1))) TransDate 
     FROM myTable WHERE YEAR(TransDate) = '+@CurrYear+' 
     GROUP BY TransDate,ItemId,ItemName) AS TP 
PIVOT (SUM(TotalCost) FOR TransDate IN ('+@MM_LIST+')) AS PVTTable'; 

EXEC sp_executesql @DynamicPivot
