Question

You can easily order by time in MYSQL, for example

"SELECT * from table WHERE date = 2012-04-29 order by time"

MYSQL will then order by the time starting with 00:00:00

My question is it possible to tell MYSQL to starting at say 06:00:00 instead of the default.

Answer 1

SELECT *
  FROM table
 WHERE date = 2012-04-29
 ORDER BY CASE WHEN hour(time) < 6 THEN 1 ELSE 0 END, time;

Stil, I find it more error prone to have date and time separated.
