Calculating timespan with t-sql

Question

Given two date/times:

@start_date = \'2009-04-15 10:24:00.000\'
@end_date = \'2009-04-16 19:43:01.000\'

Is it possible to calculate the tim

Answer 1

You can get the difference between the two dates to whatever resolution you want (in your example, minutes):

DATEDIFF(minute, @start_date, @end_date)

From there it's a simple matter of dividing minutes into hours and hours into days and modding the remainder.
