----------------------------------

> Criteria Projections.countDistinct() function broken
> ----------------------------------------------------

> Key: HHH-4957
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4957
> Project: Hibernate Core
> Issue Type: Bug
> Components: core
> Affects Versions: 3.5.0-CR-2
> Environment: Hibernate: 3.5.0-CR-2
> OS: Windows XP (should be OS independent)
> IDE: Eclipse 3.5 Galileo
> Reporter: Olaf Muliawan
> Priority: Blocker
> Attachments: HibernateCriteriaDistinctCount.zip

> The criteria countDistinct() does not generate the correct query:
> criteria.setProjection(Projections.countDistinct("id"));
> generates: select count(id)
> instead of: select count(distinct id)
> This used to work in version 3.3.2-GA with toSqlString(). This method is missing in 3.5.0
> Working version in 3.3.2-GA: http://viewvc.jboss.org/cgi-bin/viewvc.cgi/hibernate/core/trunk/core/src/main/java/org/hibernate/criterion/CountProjection.java?revision=14993&view=markup
> Broken version in 3.5.0: http://viewvc.jboss.org/cgi-bin/viewvc.cgi/hibernate/core/trunk/core/src/main/java/org/hibernate/criterion/CountProjection.java?revision=17874&view=markup
