This trigger has an argument passed. When the trigger is "assigned"I know whether the column is of type txt or float.
It uses the column name to determine what to do.
Hope this helps Allan
create or replace function insert_if_diff() returns trigger as$BODY$declare r record;
begin for r in execute 'select ' || TG_ARGV[0] || ' from ' || TG_TABLE_NAME || ' order by dt desc limit 1;' loop if TG_ARGV[0] = 'value' then if new.value = r.value then return null; end if; end if;
if TG_ARGV[0] = 'txt' then if new.txt = r.txt then return null; end if; end if;
return new; end loop;
return NEW;end;
