CTE問題，執行錯誤。無法創建總結報告

Question

我想創建一個總結報告。我對CTE完全陌生。

錯誤的詳細信息：

消息102，級別15，狀態1，行1個
附近有語法錯誤。「。
Msg 102，Level 15，State 1，Line 11
'，'附近的語法不正確。

代碼：

WITH T1(PlannedFY, Media_Activity_Type.[Type], ReportingQuarter, Summary, ID) AS 
(
    SELECT 
     COUNT(MediaActivities.MediaActivityId) AS [PlannedFY], 
     Media_Activity_Type.[Type] AS [ID], 
     MediaActivities.ReportingQuarter, 
     MediaActivities.Summary, 
     MediaActivities.TypeId 
    FROM 
     Media_Activity_Type 
    INNER JOIN 
     MediaActivities ON Media_Activity_Type.TypeId = MediaActivities.TypeId 
    GROUP BY 
     MediaActivities.MediaActivityId, Media_Activity_Type.[Type], 
     MediaActivities.ReportingQuarter, MediaActivities.Achivied, 
     MediaActivities.Summary, MediaActivities.TypeId 
), 
T2(Achieved, ID) AS 
(    
    SELECT  
     COUNT(MediaActivities.Achivied) AS [Achieved], 
     Media_Activity_Type.TypeId AS [ID] 
    FROM   
     MediaActivities 
    INNER JOIN 
     Media_Activity_Type ON MediaActivities.TypeId = Media_Activity_Type.TypeId 
    GROUP BY 
     Media_Activity_Type.TypeId, MediaActivities.Achivied 
    HAVING 
     MediaActivities.Achivied = 1 
)  
SELECT 
    T1.*, T2.Achieved 
FROM 
    T1  
INNER JOIN 
    T2 ON T1.ID = T2.ID 

Answer 1

的 「參數」 爲with部分定義列別名，它們不引用 「真實」 的列。所以，你應該改變：

​​3210

到

WITH T1(PlannedFY,[Type],ReportingQuarter,Summary,ID) 

它說「創造一個CTE與列PlannedFY，[Type]，ReportingQuarter，Summary和ID

Answer 2

您也正在做計數（MediaActivities .MediaActivityId）並在你的羣組中使用，因此你可能總會得到1的計數。 你可以簡化查詢：

WITH T1 AS 
(
    SELECT 
     COUNT(MediaActivities.MediaActivityId) AS [PlannedFY], 
     Media_Activity_Type.[Type] AS [ID], 
     MediaActivities.ReportingQuarter, 
     MediaActivities.Summary, 
     MediaActivities.TypeId 
    FROM 
     Media_Activity_Type 
    INNER JOIN 
     MediaActivities ON Media_Activity_Type.TypeId = MediaActivities.TypeId 
    GROUP BY 
    -- MediaActivities.MediaActivityId, 
     Media_Activity_Type.[Type], 
     MediaActivities.ReportingQuarter, 
     MediaActivities.Achivied, 
     MediaActivities.Summary, 
     MediaActivities.TypeId 
), 
T2 AS 
(    
    SELECT  
     COUNT(MediaActivities.Achivied) AS [Achieved], 
     Media_Activity_Type.TypeId AS [ID] 
    FROM   
     MediaActivities 
    INNER JOIN 
     Media_Activity_Type ON MediaActivities.TypeId = Media_Activity_Type.TypeId 
    GROUP BY 
     Media_Activity_Type.TypeId, MediaActivities.Achivied 
    HAVING 
     MediaActivities.Achivied = 1 
)  
SELECT 
    T1.*, T2.Achieved 
FROM 
    T1  
INNER JOIN 
    T2 ON T1.ID = T2.ID
