MySQL datetime field query sort by hour: minute

I have a table like this:

id  date_time
1   2/11/2013 7:05
2   2/11/2013 7:00
3   2/12/2013 7:00
4   2/14/2013 7:00
5   2/16/2013 7:00
6   2/17/2013 7:00
7   2/12/2013 7:05
8   2/14/2013 7:05
9   2/15/2013 7:05
10  2/16/2013 7:05
11  2/17/2013 7:05
12  2/13/2013 7:00
13  2/15/2013 7:00
14  2/13/2013 7:05

I need to sort it by HOUR: MINUTE and than sorted by DATE, so I get something like this in the output:

2/11/2013 7:00
2/12/2013 7:00
2/13/2013 7:00
2/14/2013 7:00
2/15/2013 7:00
2/16/2013 7:00
2/17/2013 7:00
2/11/2013 7:05
2/12/2013 7:05
2/13/2013 7:05
2/14/2013 7:05
2/15/2013 7:05
2/16/2013 7:05
2/17/2013 7:05

Is there a way to sort the output directly from MySQL? ... I know I can do this via PHP after getting the query results, but just wondering if MySQL can do something like this?

I tried a query like this:

SELECT * FROM my_table WHERE (date_time BETWEEN '$date_check_low' AND '$date_check_high') ORDER BY hour(date_time) ASC

but it produces strange results ...

ORDER BY HOUR(date_time), MINUTE(date_time), date_time

or



ORDER BY TIME(date_time), date_time

Try the following:



SELECT *
FROM my_table
WHERE (date_time BETWEEN '$date_check_low' AND '$date_check_high')
ORDER BY time(date_time),
         date_time;
