With the following sample table:
ID , StartDistance, EndDistance, Date
1, 10, 12, 01/01/2004
2, 8, 11, 01/02/2004
3, 13, 14, 01/01/2004
4, 13, 14, 01/03/2004
5, 17, 25, 01/01/2004
6, 19, 20, 01/02/2004
7, 19, 23, 01/03/2004
8, 20, 23, 01/02/2004
I need to return all rows that don’t overlap (as in cover the same or part or another records inclusive start to end distance) or if they do the record with the latest date will be returned.
So from the sample data I would retun IDs:
2
4
7
I know I can do this using cursors but I'm sure in the back of my head I can do this in a single query but my grey matter is struggling to come up with the answer
Cheers in advance
