sql-server-2008 - 执行时出现 CURSOR 表错误：函数中包含的 Select 语句无法将数据返回给客户端

Question

我正在尝试使用 CURSOR 表在我的函数中传递两个值。这个对吗？我从之前修改了这篇文章。当我执行这个函数时，它执行成功。只是不确定如何在 SQL 中进行测试。

 USE [PMCLW1]
 GO
 /****** Object:  UserDefinedFunction [dbo].[func_PNMS_CA]    Script Date: 08/13/2013 14:41:16 ******/
 SET ANSI_NULLS ON
 GO
 SET QUOTED_IDENTIFIER ON
 GO
 ALTER function [dbo].[func_PNMS_CA](@SCRDET_Seqid int, @JobSeqid int) 
 returns varchar(5000)
 as
 begin
declare @retVal varchar(5000),
        @temp varchar(1000)

declare CACur CURSOR FOR

SELECT top 1 isnull (SPCOPS_Answer, '') FROM SPCOPS WHERE SCRDET_Seqid = @SCRDET_Seqid

declare CACur CURSOR FOR

SELECT b.JBSTAT_Description
          FROM JBWORK a
            inner join JBSTAT b on a.JBSTAT_SEQID = b.JBSTAT_SEQID
          WHERE  a.PRJOBS_SEQID = @JobSeqid
          and a.dptmnt_seqid=7

OPEN CACur

FETCH NEXT FROM CACur 
INTO @temp

set @retVal = ''

WHILE @@FETCH_STATUS = 0
BEGIN

    IF len(@retVal) = 0 set @retVal = @temp
    ELSE set @retVal = @retVal + ', ' + @temp

    FETCH NEXT FROM CACur 
    INTO @temp
END

close CACur
deallocate CACur

return @retVal
 end
