Re: [PATCH] NPE in meta data getPrimaryKeys()

Actually, I had a look at the spec more carefully and what i wrote
earlier will not work nor should it

in the jdk 1.4 docs catalog, and schema can be null, but table can't be
null, it has to match exactly, so it is true, either the driver iterates
through all the tables, or the user and since the spec indicates that
the user should, then  I think the driver is correctly implemented
