[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2893) Criteria api does not allow a groupProperty to _NOT_ be included in the selected columns

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2893?page=c... ] Antony Stubbs commented on HHH-2893: ------------------------------------ P.s. The test case for the exclusion of the group by for this criteria: Criteria exclude = s.createCriteria(Student.class).setProjection(Projections.projectionList().add( Projections.max("studentNumber")).add( Projections.groupProperty("name", true)) ); produces this sql: select max(this_.studentId) as y0_ from Student this_ group by this_.name As opposed to this sql for inclusion: select max(this_.studentId) as y0_, this_.name as y1_ from Student this_ group by this_.name The default behaviour where you don't specify an option: Criteria exclude = s.createCriteria(Student.class).setProjection(Projections.projectionList().add( Projections.max("studentNumber")).add( Projections.groupProperty("name") ); produces the same result as if you chose to not exclude it select max(this_.studentId) as y0_, this_.name as y1_ from Student this_ group by this_.name I have only tested this on the default db (hsqldb) as the test runner uses. This should definitely be tested on the other databases as well. Do you have a process for doing that? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
