Hello, I'm developing a web application using Java (NetBeans 6.0) and Hibernate 3.3, in this application the user can create or delete new tables; for this operation I can't use the mapping files and java classes to define and manipulate the structure of those tables (they didn't exists yet when I write the code of the program) so I would use an HQL query like CREATE TABLE, ALTER TABLE ecc, how can I do this?
Thanks

I am not sure HQL can do this, but you could use regular SQL as Hibernate supports native SQL queries.

But why would you want to allow a user to create and delete tables in the first place? It can be a good solution in specific cases, but it often a sign of bad design.
