How to convert the time difference to hours(with 2 decimal place) in derby?

Question

Hi,

I am using timestampdiff in derby db to retrieve the time difference between 2 time: startdate, and enddate. e.g.

startdate = 2010-02-23 02:59:52.045 enddate = 2010-02-23 03:45:39.898

select {fn timestampdiff(SQL_TSI_HOUR, startdate, enddate)} as diff 

I would like to know how can I get the time diff in hours, e.g. 0.25, etc?

Thank you.

Answer 1

select {fn timestampdiff(SQL_TSI_MINUTE, startdate, enddate)}/60 as diff 

and I would call the variables startdatetime and enddatetime.
