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'.

一个快速的方法是添加一个新参数“@Column_Name”，并让调用函数定义要检索的列名。在你的sproc的返回部分，你会有if/else语句并只返回指定的列，或者如果为空-返回所有。

CREATE PROCEDURE [dbo].[MySproc]
        @Column_Name AS VARCHAR(50)
AS
BEGIN
    IF (@Column_Name = 'ColumnName1')
        BEGIN
            SELECT @ColumnItem1 as 'ColumnName1'
        END
    ELSE
        BEGIN
            SELECT @ColumnItem1 as 'ColumnName1', @ColumnItem2 as 'ColumnName2', @ColumnItem3 as 'ColumnName3'
        END
END

CREATE TABLE #Result
(
  ID int,  Name varchar(500), Revenue money
)
INSERT #Result EXEC RevenueByAdvertiser '1/1/10', '2/1/10'
SELECT * FROM #Result ORDER BY Name
DROP TABLE #Result

CREATE PROCEDURE [dbo].[MySproc]
        @Column_Name AS VARCHAR(50)
AS
BEGIN
    IF (@Column_Name = 'ColumnName1')
        BEGIN
            SELECT @ColumnItem1 as 'ColumnName1'
        END
    ELSE
        BEGIN
            SELECT @ColumnItem1 as 'ColumnName1', @ColumnItem2 as 'ColumnName2', @ColumnItem3 as 'ColumnName3'
        END
END

要实现这一点，首先你创建一个#test_table，如下所示:

create table #test_table(
    col1 int,
    col2 int,
   .
   .
   .
    col80 int
)

现在执行过程并将值放在#test_table中:

insert into #test_table
EXEC MyStoredProc 'param1', 'param2'

现在你从#test_table中获取值:

select col1,col2....,col80 from #test_table

如果您这样做是为了手动验证数据，您可以使用LINQPad。

在LinqPad中创建一个到数据库的连接，然后创建类似于下面的c#语句:

DataTable table = MyStoredProc (param1, param2).Tables[0];
(from row in table.AsEnumerable()
 select new
 {
  Col1 = row.Field<string>("col1"),
  Col2 = row.Field<string>("col2"),
 }).Dump();

如果你只需要这样做一次，最简单的方法是:

在导入和导出向导中导出到excel，然后将此excel导入到表中。
