> The implementation of generators (aka sequences) is very simple, There's a

table, RDB$GENERATORS that holds the generator name and it's ID. The id is
an index into the array of generators. Generators are stored on special
database pages which have a header and a chunk of the array. Each element
in the array is a 64 bit integer. When the value of a generator is changed,
whether by incrementing it or resetting it, the value in the array entry
changes. Nothing counts the number of changes.

Good luck,
