/filter/byrange

URL: http://GPUDB_IP_ADDRESS:GPUDB_PORT/filter/byrange

Calculates which objects from a table have a column that is within the given bounds. An object from the table identified by input parameter table_name is added to the view input parameter view_name if its column is within [input parameter lower_bound, input parameter upper_bound] (inclusive). The operation is synchronous. The response provides a count of the number of objects which passed the bound filter. Although this functionality can also be accomplished with the standard filter function, it is more efficient.

For track objects, the count reflects how many points fall within the given bounds (which may not include all the track points of any given track).
