从存储过程的结果集中选择列

我有一个存储过程，它返回80列和300行。我要写一个select函数，它能得到2个这样的列。类似的

SELECT col1, col2 FROM EXEC MyStoredProc 'param1', 'param2'

当我使用上面的语法时，我得到了错误:

“无效的列名”。

我知道最简单的解决方案是更改存储过程，但我没有编写它，也不能更改它。

有什么办法能让我如愿以偿吗?

I could make a temp table to put the results in, but because there are 80 columns so I would need to make an 80 column temp table just to get 2 columns. I wanted to avoid tracking down all the columns that are returned. I tried using WITH SprocResults AS .... as suggested by Mark, but I got 2 errors Incorrect syntax near the keyword 'EXEC'.Incorrect syntax near ')'. I tried declaring a table variable and I got the following error Insert Error: Column name or number of supplied values does not match table definition If I try SELECT * FROM EXEC MyStoredProc 'param1', 'param2' I get the error : Incorrect syntax near the keyword 'exec'.

知道这为什么如此困难也许会有所帮助。存储过程可以只返回文本(print 'text')，也可以返回多个表，或者根本不返回表。

所以像SELECT * FROM (exec sp_tables) Table1这样的东西将不起作用

我知道从sp执行和插入到临时表或表变量将是一个选项，但我不认为这是你的要求。根据您的要求，以下查询语句应该工作:

Declare @sql nvarchar(max)
Set @sql='SELECT   col1, col2 FROM OPENROWSET(''SQLNCLI'', ''Server=(local);uid=test;pwd=test'',
     ''EXEC MyStoredProc ''''param1'''', ''''param2'''''')'
 Exec(@sql)

如果你有可信连接，那么使用下面的查询语句:

Declare @sql nvarchar(max)
Set @sql='SELECT   col1, col2 FROM OPENROWSET(''SQLNCLI'', ''Server=(local);Trusted_Connection=yes;'',
     ''EXEC MyStoredProc ''''param1'''', ''''param2'''''')'
 Exec(@sql)

如果运行上面的语句出错，那么只需运行下面的语句:

sp_configure 'Show Advanced Options', 1
GO
RECONFIGURE
GO
sp_configure 'Ad Hoc Distributed Queries', 1
GO
RECONFIGURE
GO

我希望这将帮助那些将面临类似问题的人。如果有人想尝试temp表或表变量，应该如下所示，但在这种情况下，你应该知道sp返回多少列，然后你应该在temp表或表变量中创建这么多列:

--for table variable 
Declare @t table(col1 col1Type, col2 col2Type)
insert into @t exec MyStoredProc 'param1', 'param2'
SELECT col1, col2 FROM @t

--for temp table
create table #t(col1 col1Type, col2 col2Type)
insert into #t exec MyStoredProc 'param1', 'param2'
SELECT col1, col2 FROM #t

您可以拆分查询吗?将存储的过程结果插入到表变量或临时表中。然后，从表变量中选择2列。

Declare @tablevar table(col1 col1Type,..
insert into @tablevar(col1,..) exec MyStoredProc 'param1', 'param2'

SELECT col1, col2 FROM @tablevar

试试这个

use mydatabase
create procedure sp_onetwothree as
select 1 as '1', 2 as '2', 3 as '3'
go
SELECT a.[1], a.[2]
FROM OPENROWSET('SQLOLEDB','myserver';'sa';'mysapass',
    'exec mydatabase.dbo.sp_onetwothree') AS a
GO

我会剪切粘贴原始SP并删除所有列，除了你想要的两列。或。我将返回结果集，将其映射到适当的业务对象，然后LINQ出这两列。

创建一个动态视图，并从中获得结果.......

CREATE PROCEDURE dbo.usp_userwise_columns_value

    @userid BIGINT

BEGIN
        DECLARE @maincmd NVARCHAR(max);
        DECLARE @columnlist NVARCHAR(max);
        DECLARE @columnname VARCHAR(150);
        DECLARE @nickname VARCHAR(50);

        SET @maincmd = '';
        SET @columnname = '';
        SET @columnlist = '';
        SET @nickname = '';

        DECLARE CUR_COLUMNLIST CURSOR FAST_FORWARD
        FOR
            SELECT columnname , nickname
            FROM dbo.v_userwise_columns 
            WHERE userid = @userid

        OPEN CUR_COLUMNLIST
        IF @@ERROR <> 0
            BEGIN
                ROLLBACK
                RETURN
            END   

        FETCH NEXT FROM CUR_COLUMNLIST
        INTO @columnname, @nickname

        WHILE @@FETCH_STATUS = 0
            BEGIN
                SET @columnlist = @columnlist + @columnname + ','

                FETCH NEXT FROM CUR_COLUMNLIST
                INTO @columnname, @nickname
            END
        CLOSE CUR_COLUMNLIST
        DEALLOCATE CUR_COLUMNLIST  

        IF NOT EXISTS (SELECT * FROM sys.views WHERE name = 'v_userwise_columns_value')
            BEGIN
                SET @maincmd = 'CREATE VIEW dbo.v_userwise_columns_value AS SELECT sjoid, CONVERT(BIGINT, ' + CONVERT(VARCHAR(10), @userid) + ') as userid , ' 
                            + CHAR(39) + @nickname + CHAR(39) + ' as nickname, ' 
                            + @columnlist + ' compcode FROM dbo.SJOTran '
            END
        ELSE
            BEGIN

                            + CHAR(39) + @nickname + CHAR(39) + ' as nickname, ' 
                            + @columnlist + ' compcode FROM dbo.SJOTran '
            END

        --PRINT @maincmd
        EXECUTE sp_executesql @maincmd
END
