Hi all,
i am trying to generate an SQL query that inner joins with another table on a part of a composite id. Somehow Hibernate does generate the where clause with the right prefix, but the actual inner join is not made. I searched google and the forum for this, however i couldnt find anything that could help me solve the problem.
Hibernate version: 3
Oracle 10g (10.2)
i hope someone can help me :)
thanks :)
my code for generating the SQL:
Code:
public List listWeekFitters(Integer week, Store store) {
Criteria fitterList = session.createCriteria(Fitters.class);
fitterList.createAlias("day", "day");
fitterList.add(Restrictions.eq("store", store));
fitterList.add(Restrictions.lt("day.week", week));
fitterList.addOrder(Order.desc("day")).addOrder(Order.asc("numbersperdivision"));
return fitterList.list();
}
my hibernate config:
Fitter.hbm.xml:
Code:
<hibernate-mapping package="model">
<class name="Fitters" table="Fitters">
<composite-id>
<key-property name="hour" column="hour" type="integer" />
<key-many-to-one name="day" column="day_fk" class="Calendar" />
<key-many-to-one name="numbersperdivision" column="numbersPerDivision_FK" class="FitterGroups" />
</composite-id>
<property name="Amount" column="Amount" type="integer" not-null="true" />
<many-to-one name="store" column="store_fk" class="Store" />
</class>
</hibernate-mapping>
Calendar.hbm.xml:
Code:
<hibernate-mapping package="model">
<class name="Calendar" table="Calendar">
<id name="day" column="day" type="java.util.Date" >
<generator class="assigned" />
</id>
<property name="week" column="week" type="integer" not-null="true" />
<property name="year" column="year" type="integer" not-null="true" />
<property name="period" column="period" type="integer" not-null="true" />
<property name="quarter" column="quarter" type="integer" not-null="true" />
<property name="season" column="season" type="integer" not-null="true" />
</class>
</hibernate-mapping>
the SQL it creates:
Code:
Hibernate: select this_.hour as hour11_0_, this_.day_fk as day2_11_0_, this_.numbersPerDivision_FK as numbersP3_11_0_, this_.Amount as Amount11_0_, this_.store_fk as store5_11_0_ from Fitters this_ where this_.store_fk=? and day1_.week<? order by this_.day_fk desc, this_.numbersPerDivision_FK asc
the SQL it should create (i think):
Code:
Hibernate: select this_.hour as hour11_0_, this_.day_fk as day2_11_0_, this_.numbersPerDivision_FK as numbersP3_11_0_, this_.Amount as Amount11_0_, this_.store_fk as store5_11_0_ from Fitters this_ inner join Calendar day1_ on this_.day_fk = day1_.day where this_.store_fk=? and day1_.week<? order by this_.day_fk desc, this_.numbersPerDivision_FK asc
the error:
Code:
