Answer 1

TO_DATE converts a string to a date. TO_CHAR converts a date to a string. What is my_date?
Edit: Just realised you said "my_date" is a string.
Try
select * from view_date
where   TO_DATE(my_date,'???')
        between TO_DATE('01-dec-2006','dd-mon-yyyy') and TO_DATE('31-dec-2006','dd-mon-yyyy');or if you are dealing with literals you can use the more compact ANSI format:
select * from view_date
where   TO_DATE(my_date,'???') between DATE '2006-12-01' and DATE '2006-12-31';Avoid 2-digit years. You have no idea the problems that caused a few years back.
