Firebird: A safe trigger for autoinc fields

17-12-2010 11903 2

As you know, Firebird doesn’t have Autoinc fields but you can use triggers and sequences (generators) in order to obtain Autoinc features. On the web you can find many example about this.

Unfortunately I can’t find examples where triggered field (autoinc field) could receive a NOT NULL value, as is in data import from script. Following common examples,  when the triggered field receives a value, the generator isn’t incremented so you may have “key violation” on future inserts.

In this document is shown a safe trigger example that can be used also when the triggered filed could receive a value.
