hello.

here is the scenario:
sp 1 inserts data in #table, #table is in sp2 and sp3
sp 2 and sp3 are datasources for 2 report dataregions.

sp 1-> sp2
Sp 1->sp3

both sp2 and sp3 have #temp table. I want to make ## global and use it with both sp2 and sp3 without using it twice.

Wondering if you could advise with?
if I should create ##table in Sp2 and do the insert but how do i use it in sp3 i mean reference wise.

thank you !!

Will sp2 ever be run while the table already exists? As in, while another copy of sp2 is running, or sp3 is running, or any other data is accessing the table?

If so, you'll need to either reconsider the design (probably your best bet), or make the table creation conditional, or make the proc wait and loop a check on the table, so it doesn't try to create a table that already exists.

If you create a globabl temporary table, one that starts with ## instead of just #, and you have a stored procedure that creates that table, then if the procedure is run while the table already exists, the procedure will fail.

Just make sure that your sp1 is called by one caller/user at the same time...

Generally the good practice is to drop objects within the same procedure where they've been created.

Of course, there are exclusions to every rule.
