Hi Scot,

My best guess is that it is an attempt to prevent errors occuring on
zero column tables, such as one that inherits other tables. It cannot
currently tell whether a table exists or not however, because it uses
SQLColumns which can return SQL_SUCCESS when used with a search pattern
that doesn't match any tables (I'm not entirely convinced that is
correct, but as noone has ever complained, I don't think it should be
changed). I guess the simple answer is to add a check for the table at
the beginning of the function and return an error there if required.

Any other thoughts?
