I am using Hibernate 3.

If I execute "session.update" and the update is not successful (e.g. value too large), the exception is not thrown immediately.

For example,

System.out.println ("pass 1");
session.update(dataBean) ;

System.out.println ("pass 2");
session.getTransaction().commit();

System.out.println ("pass 3");

I find if session.update(dataBean) fails, "pass 1" and "pass 2" are printed but "pass 3" is not printed. That meams Hibernate will not throw exception until I execute "commit". Can I force it to throw immediately (i.e. only "pass 1" will be printed) ?


Thanks in advance.

if your HQL/SQL/mapping-file is incorrect (e.g. wrong column names) then the error occurs when you trigger commit() to the database. Not before.

so What can I do to make it throw immediately? Anything set in the config file?

Instead of session.commit(), you can invoke session.flush() which will throw exception if there is anything wrong.
