從功能在存儲過程返回多個值 - SQL服務器

Question

SP1

ALTER procedure [dbo].[sp1]    
as    
begin       
DECLARE @od varchar(255) 
EXEC @od =dbo.getFn 

SELECT CMSA.A,CMSB.B, @OD 
FROM CMSA INNER JOIN CMSB 
GROUP BY CMSA.A, CMSB.B 
end 

FN1

ALTER FUNCTION [dbo].[getFn]() 
returns varchar(255) 
as 
BEGIN 
DECLARE @Desc1 varchar(200) 
DECLARE @Desc2 varchar(200) 
DECLARE c1 CURSOR FOR 
SELECT CMSC.C 
FROM CMSC INNER JOIN CMSB INNER JOIN CMSC 
WHERE CMSC.C = "HELLO" OR CMSC.C = "GOODBYE" 
GROUP BY CMSC.C 
Open c1 
FETCH NEXT FROM c1 INTO @Desc1 
set @Desc2=@Desc1 
CLOSE c1 
deallocate c1 
Return @Desc2 
end 

只說了CMSC現有值是HELLO和GOODBYE了，我想同時顯示值從函數存儲過程。例如，

CMSA.A, CMSB.B, HELLO 
CMSA.A, CMSB.B, GOODBYE 

但現在，我只能夠顯示一個輸出，而不是如上所述的兩個輸出。我該如何解決這個問題？

功能

的功能似乎錯誤的內連接沒有ON語句。

ALTER FUNCTION [dbo].[getFn]() 
returns @table TABLE (value varchar(255)) 
as 
BEGIN 
    DECLARE @Desc1 varchar(200) 
    DECLARE @Desc2 varchar(200) 

    DECLARE c1 CURSOR FOR 

    SELECT CMSC.C 
    FROM CMSC 
    INNER JOIN CMSB 
    INNER JOIN CMSC 
    WHERE CMSC.C = "HELLO" OR CMSC.C = "GOODBYE" 
    GROUP BY CMSC.C 

    Open c1 
    FETCH NEXT FROM c1 INTO @Desc1 
    set @Desc2=@Desc1 
    INSERT INTO @table VALUES (@Desc2) 
    CLOSE c1 
    deallocate c1 

    Return 
end 

SP

同樣，SP的語法也是錯誤的，因爲在ON語句中缺少INNER JOIN。

ALTER procedure [dbo].[sp1]    
as    
begin       
DECLARE @od varchar(255) 
EXEC @od =dbo.getFn 

SELECT CMSA.A,CMSB.B, a.Value 
FROM CMSA INNER JOIN CMSB 
INNER JOIN (SELECT * FROM dbo.getFn()) a 
GROUP BY CMSA.A, CMSB.B 
end 

這可能是一個INNER JOIN或取決於是否有一個字段上
