                问题描述

                代码如下:

                ALTER PROCEDURE dbo.pdpd_DynamicCall 
                @SQLString varchar(4096) = null
                
                AS
                
                Begin
                
                    create TABLE #T1 ( column_1 varchar(10) , column_2 varchar(100) )
                
                    insert into #T1 
                        execute ('execute ' + @SQLString )
                
                    select * from #T1 
                
                End
                

                问题是我想调用可以返回不同列的不同过程.因此,我必须一般地定义表 #T1.但我不知道如何.

                The problem is that I want to call different procedures that can give back different columns. Therefore I would have to define the table #T1 generically. But I don't know how.

                有人能帮我解决这个问题吗?

                Can anyone help me on this problem?

                推荐答案

                尝试:

                SELECT into #T1 execute ('execute ' + @SQLString )
                

                这闻起来真的很糟糕,就像一个 sql 注入漏洞.

                And this smells real bad like an sql injection vulnerability.

                更正(根据@CarpeDiem 的评论):

                correction (per @CarpeDiem's comment):

                INSERT into #T1 execute ('execute ' + @SQLString )
                

                此外,如果 sql 字符串不是过程,则省略 'execute'

                also, omit the 'execute' if the sql string is something other than a procedure
