An Essential Guide to the Oracle Sequence By Practical ExamplesLearn what a sequence is and how to use the NEXTVAL pseudo-column to generate unique integers in Oracle. See examples of creating, using, modifying, and removing a sequence object in SQL and PL/SQL.
A sequence is a schema object that can generate unique sequential values. These values are often used for primary and unique keys. You can refer to sequence values in SQL statements with these pseudocolumns: CURRVAL: Returns the current value of a sequence. NEXTVAL: Increments the sequence and returns the next value.
After a sequence is created, you can access its values in SQL statements with the CURRVAL pseudocolumn, which returns the current value of the sequence, or the NEXTVAL pseudocolumn, which increments the sequence and returns the new value.
