錯誤在「return」語句

我已經在sql server中寫了一個表值函數，並且在「return語句」中面臨錯誤代碼中的所有語句都是正確的，但我不知道爲什麼會出現此錯誤錯誤在「return」語句

我的錯誤是

Incorrect syntax near the keyword 'RETURN'.

我的SQL函數是

不知道爲什麼它會告訴你錯誤在'RETURN'上，但是這對一個函數是無效的：'EXEC SP_EXECUTESQL @ QUERY' – Lamak 2013-03-14 13:51:50

在「RETURN」之前立即改變「DROP TEMP」到DROP TABLE TEMP「 – 2013-03-14 14:16:19

Lamak是正確的，你不能使用EXEC或SP_EXECUTESQL或類似的功能。

也許你可以重寫你的函數到存儲過程？

關於語法錯誤，你不應該寫DROP TABLE TEMP而不是DROP TEMP？

同意這應該是一個存儲過程，而不是一個函數。另外，'RETURN'應該指定一個值，例如'RETURN 0'。 – 2013-03-14 16:16:21
