I have a DT field that I want to break into 1/2hr designators (so 1-48). Is there a better way to do this than with just a lengthy CASE WHEN (or "old school" IF THEN ELSE)?
So, for example 03/12/2014 12:05:30am becomes 1 (1st half hour after midnight), while 03/12/2014 11:37:33pm would be 48 (last half hour before midnight).
Thanks much!
