How to get the SQL query from a PreparedStatement?

Hi!

Is it possible to get the query string (including the formatted
parameters) from a PreparedStatement?

The idea is to get the query text, to send it into an stored procedure
to be executed within the sp (with some other stuff).  This is an idea
I had to simulate variable parameter lists in stored procs.  Is it
possible?

Thanks in advance,

Andres
