I am trying to execute my own sql query using hibernate 3.3.2.GA.
I have the following query.
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 the Dept class
<?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 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 am I getting the following error? It will convert my request to
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.
