  If I have the following:

   - insert into user ("user_id", "name") values ('1','test')

 I want to pass the above string as a parameter to a Java function,
because I might have to modify it and even pass the query to a
different DB.

  In the case that this can not be done at all, I guess I could obtain
the data that was inserted to the DB with a SELECT and then pass it to
a java function?

  I'm sorry if I'm being a little vague on the subject, but like I
said I'm new to pljava and these are just some ideas I need to test
for a project I'm developing.
