Question

Is there an easy way in SQL Server (2010) to exec a stored procedure (that returns a table) and sum a column in one (or a few) statements?

eg

SELECT SUM(column) FROM exec proc_GetSomeStuff 'param1', 'param2'

Answer 1

Don’t have a server handy to test with, but try this:

declare @temp table(col1 int)

insert into @temp(col1)
exec proc_GetSomeStuff 'param1', 'param2'

select sum(col1) from @temp

Make sure your table variable (or temp table) has the same schema as the results of the stored procedure. If you know that there will be a significant number of rows coming back from the SP, then a temporary table might be a better option. (I’m not sure if table variables can be flushed out to disk if they get too big)
