Video #63
In this 5 minute video I show you how to use SQL Select to access the geometry of an object. In this example I extract the AREA of 3 polygons using a column alias
I also show you how to use Update Column to actually write that AREA information to a field in the MapInfo TAB file.
And finally, I demonstrate using SUM to add together the 3 AREA for the 3 polygons.
