GPUdb.create_trigger_by_range( request_id = None, table_names = None,
column_name = None, _min = None, _max = None,
options = {} )
Sets up a simple range trigger for a column_name for one or more tables. Once the trigger has been activated, any record added to the listed tables(s) via insert_records with the chosen column_name's value falling within the specified range will trip the trigger. All such records will be queued at the trigger port (by default '9001', but able to be retrieved via show_system_status) for any listening client to collect. Active triggers can be cancelled by using the clear_trigger endpoint or by clearing all relevant tables.
The output returns the trigger handle as well as indicating success or failure of the trigger activation.
