Sequence

Sequence is a feature supported by some database systems to produce unique values on demand.

Syntax:
CREATE Sequence sequence-name
start with initial-value
increment by increment-value
maxvalue maximum-value
cycle|nocycle

where,

initial-value specifies the starting value of the Sequence.
increment-value is the value by which sequence will be incremented.
maxvalue specifies the maximum value until which sequence will increment itself.
Cycle specifies that if the maximum value exceeds the set limit, sequence will restart its cycle from the begining.
No cycle specifies that if sequence exceeds maxvalue an error will be thrown.
