Question

I have a bunch of records in a MySQL table, each with a date attribute (m.d.Y), and a time attribute stored as hr:min:sec. I want to sort them chronologically based on both the date and the time. How would I do that with PHP/MySQL?

Edit: If you think there’s a more efficient way at storing my date and time in the database, please let me know.

Yes, make a field of datetime or timestamp in your table, create an index by this field and sort by it.

Queries:

/* add a column */
alter table `table` add column `created_at` datetime not null default "0000-00-00 00:00:00"
/* create an index */
alter table `table` add index `created_at` (`created_at`)
/* sort */
select * from `table` order by `created_at`
