A sequence name identifies a sequence of values.
<sequence_name> ::= <identifier>
A sequence is a series of values that are generated in accordance with certain rules. The step width between these values can be defined, among other things.
Sequences can be used to generate unique values. These are not uninterrupted, because values generated within a transaction that was rolled back cannot be used again.
An error message occurs if the name has more than 32 characters.
