That is roughly what I was thinking - though it could go either way, couldn't it, since the description of the original function probably didn't say "only user tables and no others"? I checked and the Ingres driver dbd_list_tables() does filter out system tables (table_name NOT LIKE 'ii%'). Maybe that should be revisited. --Toby > i.e. those usually created by the user or some piece of software?
