[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2681) Aggregate projection aliases should not be applied to where-clause
Aggregate projection aliases should not be applied to where-clause
------------------------------------------------------------------
Key: HHH-2681
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2681
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.4.sp1
Reporter: Dmitry Katsubo
Priority: Minor
Please, have a look at the following expression:
Criteria criteria = session.createCriteria(ClauseStatisticsImpl.class);
criteria.setProjection(
Projections.projectionList()
.add(Projections.groupProperty("clause"), "clause")
.add(Projections.max("useDate"), "useDate"))
.add(Property.forName("useDate").eq("2007-12-12"));
criteria.addOrder(Order.desc("useDate")).setMaxResults(20).list();
The problem is that the "eq" expression is applied to groupped property. This is
not correct and causes SQL exception. Aliases defined for aggregate projections, should be
only allied to "group", "having" and "order" clauses.
The mapping is:
<class name="ClauseStatisticsImpl"
table="stc_clause_statistics">
<cache usage="read-write"/>
<composite-id>
<key-many-to-one name="clause" column="clauseId"
class="ClauseImpl"/>
<key-property name="useDate"/>
</composite-id>
</class>
The error is:
12:32.22 [ERROR] org.hibernate.util.JDBCExceptionReporter - Column not found: Y1_ in
statement [select top ? this_.clauseId as y0_, max(this_.useDate) as y1_ from
