In this tutorial, we will introduce Generators with an example that will combine with a trigger to create unique values for a record as its inserted into the database. Generators are unique Integer values that are specific to each database. You can use Generators from negative Integer to positive Integer to get unique values for use in, for example, primary keys. Using Generators is a positive thing as they are managed by the database to ensure their uniqueness: You can have multiple Generators on any one database.
