EXPERT RESPONSE
So long as the stored procedure produces only a single result, the technique for using the output of one stored procedure in another is pretty straightforward. The technique is to use a temporary table to hold the results of the stored procedure and an INSERT EXEC statement to execute the sproc and save the results. Once the results are in the temporary table they can be used like any other table data.
Here's an example procedure that we might like to reuse:
CREATE PROC usp_Demo_AllAuthors as
select * from pubs..authors
GO
Now here's a stored procedure that uses the results of usp_Demo_AllAuthors:
CREATE proc usp_Demo_SPUser as
CREATE TABLE #Authors (
au_id varchar(11) NOT NULL PRIMARY KEY CLUSTERED,
au_lname varchar (40) NOT NULL ,
au_fname varchar (20) NOT NULL ,
phone char (12) NOT NULL,
address varchar (40) NULL ,
city varchar (20) NULL ,
state char (2) NULL ,
zip char (5) NULL ,
contract bit NOT NULL
)
-- Execute usp_Demo_AllAuthors storing the
-- results in #Authors
insert into #Authors
exec usp_Demo_AllAuthors
-- Here we use the #Authors table. This example only
-- only selects from the temp table but you could do much
-- more such as use a cursor on the table or join with
-- other data.
SELECT au_fName + ' ' + au_lname as [name]
, address+', '+city+', '+state+' '+zip [Addr]
from #Authors
DROP TABLE #Authors
GO
