[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2919) HQL DELETE and map entity mode
HQL DELETE and map entity mode
------------------------------
Key: HHH-2919
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2919
Project: Hibernate3
Issue Type: Bug
Components: caching (L2), core, query-hql
Affects Versions: 3.2.5
Environment: org.hibernate.transaction.JDBCTransactionFactory as factory_class,
postgresql 8.x with postgresql-8.1-407.jdbc3.jar JDBC driver, Linux 2.6.22-gentoo-r8 i686
Pentium III (Coppermine)
Reporter: Cédric Chantepie
Cache trouble when deleting object mapped in map mode (dynamic-map) with an HQL DELETE
query, where as if deleted with session.delete(...) it works.
In xxx.hbm.xml :
<!-- Entity mapping -->
<class entity-name="Test"
table="test"
lazy="false">
<composite-id>
<key-property name="name" column="name"
type="string" />
<key-property name="type" column="ptype"
type="integer" />
</composite-id>
<property name="value" column="value" type="string"
/>
</class>
<!-- endOf Entity mapping -->
JUnit test code :
Map t = null;
try {
t = new HashMap(3);
t.put("name", "Test1");
t.put("type", new Integer(2));
t.put("value", "---");
session.save("Test", t);
} catch (Exception e) {
fail(e.getMessage());
}
try {
t = (Map) session.get("Test", (Serializable) t);
assertNotNull(t);
} catch (Exception e) {
fail(e.getMessage());
}
try {
Query q = session.createQuery("DELETE FROM Test t " +
"WHERE t.name = :name");
q.setString("name", "Test1");
assertTrue(q.executeUpdate() == 1);
//WORK:session.delete("Test", (Serializable) t);
} catch (Exception e) {
fail(e.getMessage());
}
try {
Map m = (Map) session.get("Test", (Serializable) t);
assertNull(m); // fails here, find the deleted object, no
ObjectDeletedException
} catch (Exception e) {
fail(e.getMessage());
}
Maybe that due to composite-id and hashCode/equals support in map mode, maybe cache is not
notified of objects deleted by HQL in this map mode.
