I am trying to execute sql native query using hibernate 3.3.2.GA.
I have following query.
Code:
session.createSQLQuery("SELECT {dept1.*}, {dept2.*} FROM Dept d1, Dept d2 WHERE d1.deptId = d2.deptId").
addEntity("dept1",com.test.pojo.Dept.class).
addEntity("dept2",com.test.pojo.Dept.class).
list();
Mapping file for Dept class is
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.test.pojo.Dept">
<id column="deptId" name="deptId" type="long">
<generator class="native"/>
</id>
<version name="version" access="field" column="version"></version>
<property generated="never" lazy="false" name="deptName" type="string" column="deptName"/>
<set name="emps" cascade="all" inverse="true">
<key column="deptId"></key>
<one-to-many class="com.test.pojo.Emp"/>
</set>
</class>
</hibernate-mapping>
But why I get following error?
Hibernate: SELECT dept1.deptId as deptId1_0_, dept1.version as version1_0_, dept1.deptName as deptName1_0_, dept2.deptId as deptId1_1_, dept2.version as version1_1_, dept2.deptName as deptName1_1_ FROM Dept d1, Dept d2 WHERE d1.deptId = d2.deptId
