sql - Convert integer to hours mysql -


i'm storing duration decimal 0.5 half hour, 2 two hours, , on. when doing calculations times, need have represented in h:i:s, 0.5 = 00:30:00.

how should approach in mysql? application small , not public consumption, , i'm not fussed if solution hackish.

my goal able use in timeadd(my_time, duration). did miss in manual?

try query

select     id,     type,     details,    duration,    sec_to_time(duration*60*60) durationintime      tbl

sql fiddle:

| id |     type |             details | duration |                 durationintime | ----------------------------------------------------------------------------------- |  1 |    email | admin@sqlfiddle.com |     10.5 | january, 01 1970 10:30:00+0000 | |  2 |  twitter |          @sqlfiddle |        5 | january, 01 1970 05:00:00+0000 | |  3 | blahblah |                 xyz |      5.5 | january, 01 1970 05:30:00+0000 |
