Query to calculate different timestamps for matching criteria

mardi 17 février 2015

Hi,

I have a table that records log entries for equipment and I'm trying to compose a query that calculates the time difference between consecutive timestamps for individual operators but can't quite get it to work out

The table headings are

Fatigue Log ID <----- this is the primary key for the table and is unique

Timestamp

Operator ID



Any ideas appreciated
