Question

I don’t believe this is possible, but want to confirm you cannot set a table variable from the results of executing a stored procedure in SQL Server 2008.

I was trying to do the following:

DECLARE @Results TABLE (RESULT_ID INT);

INSERT INTO @Results (RESULT_ID) VALUES (1);

SET @Results = 
EXEC dbo.[spResultLookup] @Results;

My goal is to pass @Results to the stored procedure and then to replace @Results with results from the call to spResultLookup.

The alternative is to delete the rows in @Results and use an INSERT with EXEC statement.

Here’s a page from documentation that demonstrates how you can pass tables into procs but it definitely stipulates that you can’t update the table with DML.

Of course you could create a temp table that would be available in scope to the caller and the proc. This is probably what you have to resort to for your use case.

CREATE table #tmp( id int, val VARCHAR(50))
go

CREATE PROC UpdateTmpTable as
begin
    insert into #tmp(id,val) values(1,'abc')
end
GO

exec dbo.UpdateTmpTable
select * from #tmp
