This field must have time type because a report is based on it. The
report is done with Crystal

Hello!
SELECT PLACE, SUM(SECOND(DURATION) +
MINUTE(DURATION)*60 + HOUR(DURATION)*60*60)
FROM MyTable
GROUP BY PLACE
But I still need to convert int to time.
Out of curiosity, what happens if you add this int to the Time 00:00:00?
I don't add this int to any Time. That won't work.
Can I ask why you wouldn't store the duration as a simple bigint
representing the number of seconds/milliseconds?

Hello!
I have a table with with time fields. That is, each record has
a) field place (string) and
b) field duration (time).
I want to run a query like this
SELECT PLACE, SUM(DURATION)
FROM MyTable
GROUP BY PLACE
But I'm getting following error message:
SQL State = 42Y22 SQL Code = 3 SQL
Well, first of all:
what do you expect as a value for (Date)A + (Date)B ?
What you want is an interval (perhaps in seconds) instead of time as
duration.

Maybe easiest way is use big int type in duration field and store duration
time in milliseconds
