DBI; correlate columns to tables

select t01.name, t02.name
from users t01, clients t02;

or

select cname, uname
from
client, users;

In the forms above, is there a way DBI can discover tables used with
the columns?  Oracle.

Thank you

I see java has something that looks interesting.  Given an index into
the projection, you can retrieve the column and it's
table.... I think.
java.sql.ResultSetMetaData;
