No, and the reason is that the JDBC driver doesn't actually parse the 
query beyond some basic manipulations to find parameter placeholders and 
so on. All the real parsing happens on the server side, and I don't know 
of a way to get access to the server's query tree as a client. (It's 
debatable how useful that would be, anyway)
