CREATE TABLE person (
id int4 primary key,
parent_id int4 references person (id),
name varchar(50)
)
SELECT * FROM person inner join person parent on person.parent_id =
parent.id
rs.getTableName() distinguishes person.name from parent.name.
In my experience, drivers correctly implement getTableName()
*far* less frequently. I've never been able to rely on it.
Of the drivers I have handy, only DB2J and MySQL get it right.
Cloudscape, Firebird, hsqldb, mssqlserver, and pg75 all return
the underlying base table name. JTDS, Oracle, and pg74 all
return empty strings!
