Adding Numbers To Date/Time Values

Tags: SQL

Ok ok, last SQL date/time post I swear. But, while testing my last entry idea, I realized you can add numbers to your date/time values. Wicked cool:

  • SELECT
  • -- Query for yesterday's date.
  • (
  • getDate() - 1
  • ) AS yesterday,
  •  
  • -- Query for tomorrow's date.
  • (
  • getDate() + 1
  • ) AS tomorrow

Just note that this leaves in the TIME value as-is.

Hi,
I have tried using date functions. But couldn't find exact.

The thing is if I type the date as such 24-08-2012 the output shd be 21-08-2012.
It shd be applicable for all the dates !!

Note : 3 days 4 hours and 22 minutes shd be included

I need the query for the scenario as its imp for one application.
