How to update/Insert random dates in SQL within a specified Date Range

Question

Please forgive me. I am an absolute newbie and I need help with this table in phpmyadmin

My Table has the following columns:

Primary_ID, Begin_Date, End_         


        

Answer 1

something like:

insert into myTable (begin_date) values date_add('2008-09-01', INTERVAL RAND()*30 DAY)

that should create a new row with a random begin_date

update myTable set Timestamp = date_add(begin_date, INTERVAL RAND()*1440 MINUTE)

then that one should set the timestamp to a random minute of that day.
