Hello All,

Could you please help me out, i am in a wierd situation,


i have a sql store procedure (about 1350 lines in it), which quries data different tables and loads data to tables (about 11 tables)

the reason, the above procedure is generating 11 tables, i am using only 4 tables in these 11, but these 11 tables were derived internally data connected,


so the requirement is, after execute the procedure we want to generate only 4 tables(which i need, presently using) , i need to consolidate the proc to generate only 4 tables.



the reason why it is generating 11 tables is,

step1 load data to table, scrub and then apply some additionl logic then prepare table 2, then some update and union and insert to table 3 (using table 2 and table 1 and some other tables... etc it will go till 11 tables)


can i use temp tables ? here in proc to replace these 11 tables, so that i will have only required 3 tables in db remain all for temporary calculation, but temp tables shoun't visible after proc exec completes in db, or any other ideas please, does temp tables stay till proc execution completes or only valid for single sql statement ......


help me here, please assist me, guide me with all open ideas


thanks in advance
asitti

You can select data into temp tables like this:


select *
into #TempTable
from dbo.table


Temp tables starting with one # exist for the session, or until you drop them. If you create them in a stored procedure, the temp tables will be dropped when it finishes.

You can drop them yourself like this:


drop table #TempTable


A simple solution might be to just drop the unwanted tables at the end of the stored procedure.
