Re: Check if table exists

Hi,

I'm a novice also, but I'm sure that one way of accomplishing this is to check the metadata table/views (eg.
information_schema.tables).

If you want to make it a little cleaner, you could always wrap the check fo the meta into a function that returns a
bool.

HTH,

David
