That is not the problem, the solution Walter used in Firebird 2.5 would work in Firebird 3 as well. The problem is that Walter switched from auto-increment columns generated by a trigger, to using identity columns. When you use a trigger, you can explicitly handle null to generate a value, but when using an identity column, then you either have to leave out the column so it is generated, or you need to specify a non-null value.
