SQL statement to get selected date - 1 day

Hello,
I have a Sybase DB and I have a Query that has the following:
DATEFORMAT(CALENDAR_DATE, 'MM/DD/YYYY') AS CALENDAR_DATE_STR

The user will input a date at a command prompt like
01/01/2011 or 07/04/2011

What I need is to change the query so that it will actually select the day before whatever was input.
So if a user puts in
01/01/2011
The query will Select
12/31/2010

Or
07/04/2011
will get
07/03/2011

Thanks

You just need to use DATEADD:

DATEFORMAT(DATEADD(dd, -1, CALENDAR_DATE), 'MM/DD/YYYY') AS CALENDAR_DATE_STR
