我覺得你真的需要支點，但在一個確切的數據集問題，你可以按照下面的方法，它有點奇怪，在T-SQl：

declare @a as int 
declare @b as int 
declare @c as int 
declare @query Varchar(Max) 

set @query = 'Select 4,103' 
DECLARE curs CURSOR FOR 
select * From 
(select 4 as a , 103 as b , 5836 as c 
Union select 4 as a , 103 as b , 5835 as c) as res 

OPEN curs 

FETCH NEXT FROM curs 
INTO @a,@b,@c 
WHILE @@FETCH_STATUS = 0 
BEGIN 
set @query = @query + ','+cast(@c as varchar) 

FETCH NEXT FROM curs 
INTO @a,@b,@c 

END 
CLOSE curs; 
DEALLOCATE curs; 
EXEC(@query)
