If you mean resultset when speaking of record, it is.

Not sure, where the java-related question is, but the statement
would look like this:
Table authors:
id int
name varchar
...
Table quotes:
id int
id_author int
quote text
...
select a.name, b.quote from authors a, quotes b
where a.id = b.id_author
Cheers, Lothar
