hello all,
in my program I have to check for a certain combination of data before I
make an insert. The check is a select statement with a join and a
function call. Now, I wonder if I could gain performance if I would
create a temporary view that contained this join and the function call
and the other constraints. There will be frequent inserts into the
underlying tables so I can't use a real cache that is only updated once
in a while (say, a temporary table).
So would a select on the view be faster or is the view really just some
shortcut for the programmer but the database behaviour actually stays
the same?
Thanks for any hints
Chantal
