> Priority: Major

> From JDBC 4.1, catalog and schema can be retrieved from the connection
> object. When we retrieve the table objects using the JDBC connection, I
> believe we could try to get catalog and schema from connection object if they
> have not been specified by user. If they are not in the connection object
> either, null will be passed.
