Hello,
I'm sure this is a simple query but haven't come up with a good
approach. Need to get the number of days between two dates. IE: today's
date: (2006-04-01 - 2006-03-05)
need to calculate the number of days between these dates.. what is the
best query statement to accomplish this?
TIA,
Mike,
You probably want to use something like this:
SELECT TO_DAYS('2006-03-15') - TO_DAYS('2006-03-01');
Thanks, that works, also using the DAYOFYEAR produces the same results as
I just found :)
appreciate the help
I'd be careful with DAYOFYEAR() if I were you.
DAYOFYEAR() only tells you which day it is within a given year. If you try
to use DAYOFYEAR to tell the difference in days between dates that are in
different years, you are certainly going to get the wrong answer. For
instance, DAYOFYEAR(2006-04-01) - DAYOFYEAR(2005-04-01) gives an answer of 0
days when the correct answer is 365.
A better choice for getting the difference between two dates in days is
probably DATEDIFF() or TO_DAYS().
