[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-1043) Added HAVING Support to Criteria

[Dustin Schultz (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dustin Schultz updated HHH-1043:
--------------------------------

    Attachment: GroupByHavingProjection.java

Attaching GroupByHavingProjection which easily supports HAVING clauses with Criteria. Others can use this as a workaround or Hibernate could integrate this with very minimal changes. (Would love to see it in 3.5).

Usage as follows (using count distinct as an example):

criteria.setProjection(new GroupByHavingProjection("someProperty1", Projections.countDistinct("someProperty2"), "=", 2));

Hibernate (or yourself if you want to compile Hibernate) could easily add this to the Projections class.
