Hi.
I'm trying to write a function that works with a temporary table. I have to
be sure that when I execute the function, it create it. Then I make a DROP
TABLE and after a CREATE TABLE. But if the table doesn't exists, the DROP
statement raises an error and the function stops. How can I resolve this
problem?

Thanks.
