Re: Updating

Following is the code that gives me the error.

 CREATE OR REPLACE FUNCTION monitor_install() RETURNS trigger AS $$
 Begin

 If NEW.p_id.association.monitoring_fluid is distinct from
Old.p_id.association.monitoring_fluid Then

 INSERT INTO p_id.devices (device_number)
 (Select mon_function from p_id.association, p_id.devices
 Where (p_id.association.mon_function <> p_id.devices.device_number
 and (p_id.association.monitoring_fluid <> p_id.devices.fluid_id
 or p_id.association.monitoring_fluid <>  p_id.devices.pipe_id))
 and p_id.association.monitor is null);

   RETURN NULL;
 END;

 $$ LANGUAGE plpgsql;

 create trigger monitorinstall before update on p_id.association
 for each row execute procedure monitor_install();
