Calculating total time from a query

Question

Hi everyone,
I have a simple database and one of the fields in this
database is time spent on stuff, for example a bike ride lasted
00:45:00, 01:33:03, 01:23:03 ETC
what I am trying to do is calculate total time. so do a sum
of that column.
Simple enough.
the column is a VarChar, I tried Time as well and well that
did not go well.
if I use mysql command line I get this:
mysql> SELECT SUM(mv_time) FROM data WHERE user_id = 2;
+--------------+
| SUM(mv_time) |
+--------------+
| 8 |
+--------------+
1 row in set (0.00 sec)
No idea how it came up with that one as 8 is incorrect
so I got a bit fancier:
mysql> SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(mv_time))) AS
mv_time FROM data WHERE user_id = 2;
+----------+
| mv_time |
+----------+
| 26:14:58 |
+----------+
1 row in set (0.00 sec)
Bingo that is correct.
but if I use that same query within cfquery I get a nice java
error telling that you can't have 26 hours in a single day.
Any ideas how I can accomplish this should be simple task?
Thank you.

Hi Cf_dev2,
How would I go about making easy for my users to submit the
seconds into the database?
for example I would want them (them being me really :) ) to
enter 01:35:00 (for one hour and 35 minutes) and then have CF or
SQL convert that to seconds (instead of having myself figure that
out manually I am no good at math)
Jdeline, I don't understand what you mean by not storing it
as comma delimited, as far as I know its not comma delimited, its
stored in a table called data along with a primary key id, userid,
date, etc
Thanks
