Previous: Native Joins Next: Basic Result set mapping using @SqlResultSetMapping

Adding joins with entity mapping.

  • We can also use addEntity() and addJoin() methods to fetch the data from associated table using tables join. The above query can be re-written as following;
A quick sample. Check out the JAVA class and SQL file
// { autofold
package com.tu.nativesqlsample;
import java.util.List;
import java.util.logging.Logger;
import org.hibernate.Session;
import com.tu.hibernate.HibernateUtil;
import com.tu.hibernate.entity.Team;
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
  • Notice the second query, which fetches the Domain details. This is the eager Loading of the requested object
  • [aliasname].* is used to return all properties of an entity. When we use addEntity() and addJoin() with join queries like above it returns both the objects, as shown above.
