Retrieving Oracle Date

I'm having hard time retrieving oracle date with the follwing sql statement:

Select * From Document Where Mydate= #" & RS("Mydate") & "#"

I get ORA-0091 invalid character error. Then I used the TO_Date function as follow:

Select * From Document Where Mydate= To_Date(RS("MyDate"),'mm/dd/yyyy')"

I get the error expected end of statement: Now When I inser an explicite date it works

Select * From Document Where Mydate= To_Date('03/28/2005'mm/dd/yyyy')"

How do I bind Mydate into a variale and use it in the TO_Date Function .
