我可以從臨時表創建功能視圖

Question

我可以使用下面的查詢創建視圖或功能嗎？它使用臨時表。我無法創建視圖或功能。

Answer 1

不能創建一個視圖，如果僅僅是因爲你正在做一些插件和其他行動。視圖是從單個查詢創建的。

關於用戶定義函數：你不能使用動態SQL，你正在做的：

EXEC ('UPDATE #T1 SET Bookings = ' + @Bookings11 + ',Revenue=' + @Revenue11 + 
    ',Area = ' + @Area11 + ' WHERE EnquiryDate = ' + '''' + @BookingDate + 
    ''' AND PID =' + @ProjectId1)  

你也不能使用臨時表。這兩個限制都記錄在這裏：http://msdn.microsoft.com/en-us/library/ms191320.aspx。

但是，您可以在存儲過程中執行所有這些操作。也可以存儲過程的輸出定向到一個臨時表或表變量，允許您使用的輸出在另一個查詢：

INSERT INTO dbo.MyTable 
(MyTableId, Column1, Column2) -- arbitrary-chosen column names 
EXEC dbo.MyStoredProcedure 

SELECT * 
FROM dbo.MyTable 
WHERE Column1 = 'Some Value' 

最後，你也許可以返工您的SQL一起工作表變量而不是臨時表，這是允許的。它也讓我覺得你的動態SQL不需要是動態的，所以你也可以消除它。

希望這會有所幫助。
