这是我的情景:

假设我有一个存储过程,我需要在一组特定的id上调用另一个存储过程; 有没有办法做到这一点？

即而不是需要这样做:

exec p_MyInnerProcedure 4
exec p_MyInnerProcedure 7
exec p_MyInnerProcedure 12
exec p_MyInnerProcedure 22
exec p_MyInnerProcedure 19

做这样的事情:

*magic where I specify my list contains 4,7,12,22,19*

DECLARE my_cursor CURSOR FAST_FORWARD FOR
*magic select*

OPEN my_cursor 
FETCH NEXT FROM my_cursor INTO @MyId
WHILE @@FETCH_STATUS = 0
BEGIN

exec p_MyInnerProcedure @MyId

FETCH NEXT FROM my_cursor INTO @MyId
END

我的主要目标是简单的可维护性(随着业务的变化,很容易删除/添加id),能够在一行中列出所有Id ...性能不应该是一个大问题

以下SQL来自Itzik Ben-Gan,用于生成数字表.这个order by (select null)部分是什么意思？谢谢.

DECLARE @number_of_numbers INT;
SELECT @number_of_numbers = 100000;

WITH    a AS ( SELECT   1 AS i
               UNION ALL
               SELECT   1

        b AS ( SELECT   1 AS i
               FROM     a AS x ,
                        a AS y

        c AS ( SELECT   1 AS i
