I have a stored procedure that returns a record set, can I select from the Stored Procedure?

ie. Select * from [name of stored procedure]

Store the result temporarily in a table variable and select from that.

You don't have to change the stored procedure to do what Peso is suggesting. Here is an example:

INSERT INTO SomeTableThatMatchesTheSproc (...)
EXEC StoredProcedureName

SELECT * FROM SomeTableThatMatchesTheSpro

But T, you have to know the structure wouldn't you? what if i want to make it dynamic?

That's correct. You must know the structure.

then you do this:


if exists (select * from master..sysservers where srvname = 'loopback')
    exec sp_dropserver 'loopback'
go
exec sp_addlinkedserver @server = N'loopback',
    @srvproduct = N'',
    @provider = N'SQLOLEDB', 
    @datasrc = @@servername
go

select * into #t from openquery(loopback, 'exec yourSproc') 
select * from #t
drop table #t
go

Go with the flow & have fun! Else fight the flow

Yes. But did you see her reply? I was just further reiterating your post since she thought you meant she had to modify her stored procedure.

Peso, you meant this right?
DECLARE @SSQL NVARCHAR(255)
SET @SSQL ='master..xp_readerrorlog'
INSERT TempErrorLog
EXEC sp_executesql @ssql

TempErrorLog has to be created prior, even with a table variable you have to define the table.

What I want to do is create a TempErrorLog table using the data and columns from the xp_readerrorlog proc.

Spirit; whats with the LInked Server?

you need to use linked server if you want to get results of the stored procedure to a table and when
you don't know how many columns the stored procedure will return.

No it is not possible to store result of sp to table variable.
You need to use permanent or temporary table

True. I was to hasty there. Madhi is right.

EDIT: You can with SQL Server 2005 and later

can the stored procedure be changed into a UDF? if so, then it can be used in the FROM clause of any query just like a table or view.

look up table valued functions for details. I think sqlteam has a few articles on the main page about how to use them.

select * into #t from openquery(loopback, 'exec yourSproc') 
select * from #t
drop table #t
go

How can we pass dynamic parameter to 'yourSproc' ? as below:
select * into #t from openquery(loopback, 'exec sp_who' + @SPID)
Thanks

Hi all,

I have a similar request but that link Peso provided does not allow you to have a dynamic result from a stored procedure. The way I understand it is that OpenQuery allows you to insert results into a temporary table if you do not know the structure of the results, however, it does not allow you to pass in parameters.

Is this correct? If so, is this something we are stuck with or is there another solution?

pass parameters to table? or based on parameter? in that case use OPENQUERY with dynamic sql.

Thank you for your quick reply visakh,

Yep, I did not explain myself very well did I lol - sorry! :(

Okay, my situation:
I have a stored procedure that I need to pass a number of parameters to which can return a different table structure depending on the parameters. I am creating another stored procedure to update some tables based on some of the information from columns from that original stored procedure. It is likely that the original stored procedure output will continue to change and so I do not want to have to keep coming back to the second stored procedure to change a table structure for each possible output of the first stored procedure.

Hope I have not lost you yet :)

So, what I need is to have OpenQuery call a stored procedure with multiple parameters and have the output (in whatever structure it comes) from the stored procedure put into a temporary table.

Ideally this would be the line but SQL Server Mgmt Studio complains about the '+' symbols:

SELECT * INTO #Temp FROM OpenQuery(LinkedServer, 'EXEC spMyStoredProc ' + @iValue1 + ', ' + @iValue2);

Please ask me if something is still not clear.

Hmm, got a bit further now. That command works if I put the whole line into a string and execute it, unfortunately, it does not allow me to access the temporary table (probably because of the session that execute is using is different to the curent stored procedure). Now if I can just get execute to output to a temporary table...

Just so it is kept simple, I have got this to work so far:
SELECT * FROM OpenQuery(LinkedServer, 'EXEC spMyStoredProc ' + @iValue1 + ', ' + @iValue2);

but only by saving that line in a variable as a VARCHAR and 'EXECUTE'ing it.

use sp_executesql to put results of sql string to temp table.

something like

SET @Sql=N'SELECT * FROM OpenQuery(LinkedServer, ''EXEC spMyStoredProc ''' + @iValue1 + ', ' + @iValue2+');'

SET @ParmDefinition = N'@iValue1 datatypehere,@iValue2 datatypehere';

then use
INSERT #Temp
EXEC sp_executesql @Sql, @ParmDefinition,@iValue1  = yourvalue, @iValue2=yourvalue

rememeber to declare #temp and variables before using it
