Thanks, We are writing some logic in SQL as workaround it will be nicer if it was built in

I can see the value in having these. FWIW, the reason we didn't implement these with the others is because they require using a calendar object, but since we're using Joda time now, perhaps this isn't such a big deal. Another option would be for you to write a UDF[1].

This is very useful for example in aggregation on dates and for UI display. You can see how it is documented for Oracle in http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions201.htm and different supported level in http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions230.htm#i1002084 (I do not need all options but at least week/month/year will be nice) I created https://issues.apache.org/jira/browse/PHOENIX-2433 From: Stephen Wilcoxon [mailto:[email protected]<mailto:[email protected]>] Sent: Wednesday, November 18, 2015 8:07 PM To: [email protected]<mailto:[email protected]> Subject: Re: Trunc () on date questions I think he's asking for trunc() to support the higher levels (not just ways to retrieve the higher level parts). Although, it's a little unclear to me exactly what the expected behavior is for a date(time) truncated to say month is (yyyy-mm-01, yyyy-mm-<last day>, or something else). I suspect it likely varies by implementation since (date_)trunc is not a standard function.
