Question

这是我的代码：

USE [MRC]
GO

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE FUNCTION [dbo].[Lookup_APN_GUID] 
(
      -- Add the parameters for the function here
      @PN_Key int
)
RETURNS UNIQUEIDENTIFIER
AS
BEGIN
      -- Declare the return variable here
      DECLARE @PN_GUID UNIQUEIDENTIFIER

      SELECT @PN_GUID = PNID
      FROM PNEB
      WHERE PNID = (@PN_Key)

      RETURN @PN_GUID
END

我收到以下错误消息：

Msg 206，Level 16，State 2 过程Lookup_PN_GUID，操作数类型冲突：int与uniqueidentifier不兼容

我尝试在标量变量声明上将int切换为nvarchar。仍然收到错误消息。 uniqueidentifier是int。我很茫然。

任何想法？

      RETURN @PN_GUID
END

整数与UniqueIdentifier不兼容
