[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2952) Support for referencing non-root entities in Criteria SQL expressions
[

Sergey Pulyaev commented on HHH-2952:
-------------------------------------
Sorry.
Yes -
1) You have to change visibility of this method to public
2) add the following method to CriteriaQueryTranslator
public CriteriaQuery getOuterQueryTranslator() {
return this.outerQueryTranslator;
}
There was no possibility to add this without rewritting Hibernate classes...
Support for referencing non-root entities in Criteria SQL
expressions
---------------------------------------------------------------------
Key: HHH-2952
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2952
Project: Hibernate Core
Issue Type: Improvement
Components: query-criteria
Affects Versions: 3.2.2
Environment: Java 5, MySQL 5.0, Eclipse 3.2
Reporter: Jacob Gyllenstierna
Assignee: Diego Plentz
Attachments: RestrictionsExt.java, SQLAliasedCriterion.java,
SQLAliasedProjection.java
It would be very helpful to be able to reference non-root entities in Criteria SQL
restrictions and projections using placeholders similar to {alias}. A very simple but
uninteresting example:
criteria.createAlias("group", "g");
criteria.add(Restrictions.sqlRestriction("{g}.id=:groupId"));
