Would something like this work?

select timstampfield, ((select min(c.timestampfield) from timefile c
where c.timestampfield > a.timestampfield) - a.timestampfield) as
timediff from timefile a

Subject: Use sql to calculate a time difference between 2 records


Afternoon everyone

I have a non-keyed file that is in chronological order. The record
contains a timestamp field.
How can I use SQL to determine the time difference (in seconds and parts
of
seconds) between one record and the next


As always any responses are MUCH appreciated

Thanks in advance
