INSERT EXEC 语句不能嵌套

2021-09-10 00:00:00 sql tsql sql-server-2008 sql-server

我有三个程序 MainProcedure,Procedure1,Procedure2

I have three Procedures MainProcedure,Procedure1,Procedure2

1) 在程序 1 中,我只有一个选择语句,

1) In Procedure1 I just have a select statement ,

2) 在程序 2 中调用程序 1 并将输出插入 #table

2) In Procedure2 am calling the Procedure1 and inserting the Output to a #table

3) 在主程序中,我正在调用程序 2 并尝试将输出插入到引发错误的 #table 中

3) In the main Procedure I am calling the Procedure2 and iam trying to insert the Output to a #table which throws an error

消息 8164,级别 16,状态 1,过程程序 2,第 10 行INSERT EXEC 语句不能嵌套.

我可以使用 Openrowset 解决这个问题,我需要使用指定服务器名称,有没有其他方法可以通过不指定服务器名称详细信息来解决这个问题

I can resolve this using Openrowset where I need to use specify Server Name ,is there any other way to solve this by not specifying the servername details

请查找示例程序以供参考

please find the sample procedure for reference

    Create Proc Procedure1
    As
    Begin
    Select 'Arun' Name, 'Pollachi' Place
    Union
    Select 'Vedaraj' Name, 'Devakottai' Place
    End
    Go



    Create Proc Procedure2
    As
    Begin
    Create Table #Table1
    (
    Name Varchar(50), Place Varchar(50)
    )
    INSERT #Table1
    Exec Procedure1
    SELECT 'Procedure2' [Source], * FROM #Table1

    DROP TABLE #Table1
    End
    Go


    Create Proc MainProcedure
    As
    Begin
    Create Table #Table1
    (
    [Source] Varchar(50), Name Varchar(50), Place Varchar(50)
    )

    INSERT #Table1
    Exec Procedure2

    select * from #Table1

    DROP TABLE #Table1
    End
    Go

任何人都可以更改我的主要程序并使其执行谢谢!!

can any one change my main procedure and make it to get executed Thanks!!

推荐答案

就像你说的,openrowset 可以工作,但除此之外我能想到的唯一方法是:

Like you said, openrowset will work, but other than that the only ways I can think of would be:

  1. 将 proc 1 和 proc 2 都更改为基于表的函数
  2. 将 proc 2 更改为 CLR 并将所有逻辑放在那里
  3. 将表作为表值参数传递
