changing date format to compare dates on the fly in mysql query

I have a database where the dates are in mm.dd.yy format. I need to compare dates to other dates that are in the same format. All I need to know is if one date comes before the other. How can I compare them using a query when they are in this format?
I want to do
 
select * from table where date > date2

Are the fields actually stored as date data type:

Or is this a character field that stores a date?

no, they're stored as varchar in "mm.dd.yy" format. So, "07.01.09" is an example of July 1st 2009. Otherwise I wouldn't even need to ask this question to compare dates as it would be very simple.

If it is string, you can try using STR_TO_DATE function on both dates and then the comparison as you have codes will work just fine.

Example usage:
SELECT * 
FROM table 
WHERE STR_TO_DATE(date, "%m.%d.%y") > STR_TO_DATE(date2, "%m.%d.%y");
