The CallableStatement interface used to execute SQL stored procedures. The JDBC API provides a stored procedure SQL escape syntax that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not.

Does Hibernate support database views?

Of course. From the point of view of Hibernate, a view is just like any other table (except that you might not be able to update or insert to a view). You can easily map a class to a view by specifying table="view_name".

In Hibernate3, you may even map an entity class to a SQL query result set using the <subselect> mapping element. This is useful if you are unable to define new views in your database.
