I am in the process of creating a database to keep of my car's fuel costs
and mileage. I am having a little bit of trouble deciding if I need to use
a rule to do what I want or a trigger. I have created a SQL function that
will update the mileage field, but when I try and create a trigger for it,
it says it needs to return OPAQUE, but if i recreate my SQL function it
won't accept OPAQUE as a return type.
Any Ideas?
