So, when you need to map the result of a SQL query to a ManyToOne association, JoinFormula ill allows you to do that. The following SQL query returns a collection of Category objects: Hibernate reads the resultset of the SQL query and tries to discover the column names and types as defined in your mapping metadata. you will see queries like this in log file: select roles0.EntityKey as Entity91, roles0.ENTITYKEY as ENTITY91680 from USERROLE roles0 where roles0.EntityKey?org.apache.commons.
