hibernate中如何执行show tables
如题:
Session session = HibernateSessionFactory.getSession();
List<?> list = session.createSQLQuery("show tables").list();
System.out.println(list);
报错:

hibernate好像不是为这种需求设计的吧。。。。
------解决方案--------------------
Java code

List<?> list = session.createSQLQuery("show tables").list();

------解决方案--------------------
探讨
Java code

List<?> list = session.createSQLQuery("show tables").list();





有这种SQL语句??

查询当前用户的所有表:
select table_name from user_tables

不能这样查的。呵呵。。要用数据源查。。。
