Key Points Sequence
A sequence is a user-defined schema-bound object that generates a series of numeric values.
Sequences are frequently used in many databases because many applications require each row in a table to contain a unique value and sequences provide an easy way to generate them.
The sequence of numeric values is generated in an ascending or descending order at defined intervals and can be configured to restart when it exceeds max_value.
