Hi,
I've already asked on pgsql-general but there was now answer so I'll
try here.
I have to play a lot with temp tables.
Could you pls, give me a hint on emulating them under Postgres.
I have to use them quite often with 10000 rows each.
I don't use indices cause I only cache a search result and don't need
any sorting, searching on temptables.
What's faster:
1)
once:
create tmptable;
many times:
delete from tmptable;
insert into tmptable select ... ;
or
2)
many times:
drop tmptable;
select ... into tmptable;
I prefer the second way since I have a lot of concurrent access and
create unique named tables under each transaction.
Unfortunately the DROP thing dumps a core under PLPGSQL function. :(
TIA,
Pawel
