    SQL unique column

    I've been scratching my head over this problem. Tried searching for a similar problem, but I can't seem to find one. So here it is:

    I have a table with 3 columns (timestamp, data1, data2)

    I want to select timestamp, data1 and data2 where timestamp is between 'now' and 'then', but where data2 is the result of timestamp between 'now + 1 seconds' and 'then + 1 seconds'.

    In other words, data1 is from 13:00 - 13:01, but data2 is from 13:01 - 13:02 if that makes any sence.

    I thought it would be a simple query, but I just can't figure out how to do it ;-\

    Any help or pointers as to how to solve this?

    Why don't you show us what you have so far?

    You already wrote some kind of pseudo-code, just code it.
