Question

我在sql server中编写了一个表值函数，并在“return语句”中遇到错误代码中的所有语句都是正确的，但我不知道为什么会出现此错误

我的错误是

Incorrect syntax near the keyword 'RETURN'.

我的sql函数是

ALTER FUNCTION [dbo].[WEEKLY_REPORT](@START_DATE DATETIME, @END_DATE DATETIME,@PRACTISE NVARCHAR(MAX))
RETURNS @WEEKLY_REPORT_DETAILS_INFORMATION TABLE

Lamak是对的，你不能在函数中使用EXEC或SP_EXECUTESQL或类似的东西。

也许你可以将你的函数重写到存储过程中？

关于语法错误，您不应该写DROP TABLE TEMP而不是DROP TEMP吗？

“return”语句中的错误
