Lets say I have two feature class,
- Points A. All the points have a unique point_id.
- Points B, these points have an ID that matches the point_id in the Points A class.
I can join these two tables using the point_id.
Now I would like to update the geometry of the points A feature class with the geometry with points B. This would be trivial in an SQL server...It would be very useful in ArcGIS file geodatabases.
UPDATE Point_A a INNER JOIN Point_B ON a.point_id=b.point_id SET A.geom=B.geom;
Perhaps this could apply to any type of geometry also.
