What are the ways to express joins in HQL?
HQL provides four ways of expressing (inner and outer) joins:-
· An implicit association join
· An ordinary join in the FROM clause
· A fetch join in the FROM clause.
· A theta-style join in the WHERE clause.
How can Hibernate be configured to access an instance variable directly and not through a setter method? By mapping the property with access="field" in Hibernate metadata.
How can a whole class be mapped as immutable?
Mark the class as mutable="false" (Default is true). This specifies that instances of the class are not mutable. Immutable classes, may not be updated or deleted by the application.
