Hi, I'm trying to create reporting query that will return entities grouped by year / mont / day ... WHERE YEAR(record_date) = 2009 GROUP BY YEAR(record_date), MONTH(record_date) or maybe something like this: SELECT COUNT(id) FROM stats WHERE YEAR(record_date) = 2009 GROUP BY DATE_FORMAT(record_date

; )));   System.out.println("Query: " + c); But I can can never get the grouping to occur ... persistence.xml shows the grouping happening. I've had to dumb down the domain model enough to convey ... . support Support That fixed the conditional grouping issue.
