Hi,

I am new to Hibernate and wanted to know the difference between Restrictions and Expression ?

Which one is better and when should I use Restrictions and when should I use Expression?


Regards,
Manish

Expression (class) has been deprecatd, instead we need to use Restrictions class
http://docs.jboss.org/hibernate/core/3.3/api/org/hibernate/criterion/Expression.html


Use

Criteria c = session.createCriteria(Some.class).add(Restrictions.add("somePropertyInClass", itsValue));
c.list();

The above shown criteria will fetch the records based on the restriction added for the property.
