I have already loaded 2 million records. Is there a way to create year & month from my doc_date ? I have used month(doc_date) which returns the month but in many lines.
Hi Michael,
I would disagree that either Month() or MonthStart() could be used here. It depends on how you want to group things. Month() returns only the month, not the year. MonthStart includes the year, and therefore is different.
Month('01/01/2013') = Month('01/01/2012')
MonthStart('01/01/2013') <> MonthStart('01/01/2012')

Hi Rob,
Certainly these functions are quite different, I've never said they are the same. The month() function returns just a month name(number) from Jan(1) to Dec(12), while the monthstart() is the full date which can be formatted in any way. So, month() often can be repalced with monthstart() with the appropriate formatting ('MMM'), at least for the presentation purpose, but not the other way around.
If Jayadevan V wants just the month name, any of these function can be used. If he wants month and year, month() can't be used but monthstart() can. Personally, I prefer using this for months:
date(monthstart(DateField),'MMM-YY') as MonthYear
