How to get the hour difference between 2 datetimestamp on derby db?

database, derby, sql

Solution

In Derby there is a TIMESTAMPDIFF:

for instance:

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

Problem

I have a sql question on derby database: ``` Select a.name, a.starttime, a.endtime From a ``` How can I add to the above sql statement such that I can get the difference in hours between the start time and end time? (I only know that for mysql there is a DATEDIFF function, but I am not sure about what function should I use for derby db) Thanks.
