I have a littel problem (but you may have the solution..? :)
In my table I have this info in one of my columns;
1 1573 1688
1 1688 1834
1 1834 2077
12 1390 1573
etc.
The first number is just a "roadnumber"
.....but the second is from meter and the third is to meter.
I want to make a query witch takes the last/third value minus the second,
because my boss wants to know the distance.
If it's possible I want to be able to store the result in a new column.
