>Description:
Dear sir,
When I execute the command "select * from user_info where regdate < now()- interval
9 day and phone_confirmed is null and email is null and last_online<now()-interval 10
day" got 770 rows result.
But when I execute "update user_info set email="1" where regdate < now()- interval 9
day and phone_confirmed is null and email is null and last_online<now()-interval 10
day" got 0 rows is updated.
Also "delete from user_info where regdate < now()- interval 9 day and phone_confirmed
is null and email is null and last_online<now()-interval 10 day" got nothing is
deleted.
Is there anything wrong on the update and delete command? Or it just a bug of MySQL
server?
Thank you!
PS : I have tested it on MySQL Server 4.010, and 4.011.
