[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3468) SQLFunction Criterion/Projection

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3468?page=c... ] joel winteregg commented on HHH-3468: ------------------------------------- SqlFunctionProjection cannot be used into a Projections.groupProperty() because a property is needed ;-) If an alias is created using: Projections.projectionList() .add(Projections.alias(new SqlFunctionProjection("date_trunc", "startDate", "hour"), "myalias")) It is not possible to use it as follow: .add(Projections.groupProperty("myalias")) because groupProperty cannot find the created alias org.hibernate.QueryException: could not resolve property: myalias of: ... Because groupProperty() method add the needed SQL statement into the SELECT statement and into the GROUP BY statement, no alias should be created. Maybe a new method like groupFunction() should be provided ? For now, the following code works well, but it does not use defined function from SQL dialect: .add(Projections.sqlGroupProjection("date_trunc('hour', startDate) as x", "x", new String[] { "x" }, new Type[] { Hibernate.STRING })) -- 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
