st: Drop Observations if Greater than A Particular Date

Hi all,
I have a simple problem but don't understand why it is currently not
working, so any help would be appreciated. I have imported data
(including dates) into Stata from a csv file and then ran code to
change it into %td format
-generate edate = date(date, "YMD") //translate string dates into lapsed dates
format edate %td
drop date
rename edate date
label variable date Date-
I then would like to drop observations where the date is greater than
20-07-2006. I did -drop if date>20072006- but that does not drop any
observations at all when I can see that there are instances where the
date is greater than this.
Do I have to convert my 20-07-2006 back into lapsed dates, then how do
I work out what value this corresponds to? I would have thought it
would be easier than this.
Thank you for your suggestions,
Lisa
