Re: selecting records newer than say 20 min
Hi, Gregory Hmm.. I think you just should add something like 'create_time DATE_SUB(NOW(), INTERVAL 20 MINUTE)' to a where clause of your query. Or something similar.. You can find more at http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html. Also consider creating of an index on your timestamp field, if your table is large.
