--- Comment #10 from mhonline <[email protected]> ---
the concept of having no record-numbers "available for users" in firebird is
weak, althought they need to have them, since they can establish
table-relations. However, the proposal of robert might not work, as the value
from "generated by default" can be overwriten. Pls see this copy from the
FB-4.0-manual:
GENERATED BY DEFAULT
An identity column of type GENERATED BY DEFAULT will generate a value on insert
if no value — other than DEFAULT — is specified on insert. When the OVERRIDING
USER VALUE clause is specified in the INSERT statement, the user-provided value
is ignored, and an identity value is generated (as if the column was not
included in the insert, or the value DEFAULT was specified).
But the solution for the problem lies somewhere in there.
I still believe, that - as stated somewhere else - the field of type identity
with autoincrement must be made "non-editable" by user, but to have additional
regular fields filled by a generator might be an option too to get a usable
workaround.
