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'.
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
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
