I want to select a date from oracle table formatted like select (to_char(req_date,'MM/YYYY')) but I also want to order the result set on this date format.

I want them to be ordered like dates not strings.

Like this

09/2009
10/2009
11/2009
12/2009
01/2010
02/2010
03/2010
04/2010
05/2010
06/2010
07/2010
08/2010
09/2010
10/2010
11/2010
12/2010

Not like

01/2010
02/2010
03/2010
04/2010
05/2010
06/2010
07/2010
08/2010
09/2009
09/2010
10/2009
10/2010
11/2009
11/2010
12/2009
12/2010

Any way to do this in sql?

full sql is select (to_char(req_date,'MM/YYYY')) as monthYear,count(req_id) as count from REQUISITION_CURRENT t group by to_char(req_date,'MM/YYYY')

Thanks
