TAbstractGenerator.RetrieveIdAfterInsert Method
Retrieves the identifier assigned by the database after the entity was inserted.
Remarks
This method is called only when GenerateId returned Unassigned.
The default implementation returns Unassigned. Override this method in generators that rely on database-side identity generation (such as auto-increment or identity columns) to fetch the generated value after the insert.
