Hi
The sql error code -804 has four different possible
meanings. Each of the four messages/meanings
has a different Interbase Number.

Questions:
Why is there two different numbering systems.
Is the SQLCode a standard like sql? If so I
can see no relation between the 4 posible
meanings of -804 for example.

What does ISC stand for.

The Interbase number is decidely long.
Is there a pattern in the number is it
used to classify error codes. All the
isc_error codes contains 335544 which
seems like a waste.

Groete
