SEQUENCES

The SEQUENCES table provides information about sequences. The sequences feature is modeled on a similar feature in MariaDB.

USE INFORMATION_SCHEMA;
DESC SEQUENCES;

The output is as follows:

+-----------------+--------------+------+------+---------+-------+
| Field           | Type         | Null | Key  | Default | Extra |
+-----------------+--------------+------+------+---------+-------+
| TABLE_CATALOG   | varchar(512) | NO   |      | NULL    |       |
| SEQUENCE_SCHEMA | varchar(64)  | NO   |      | NULL    |       |
| SEQUENCE_NAME   | varchar(64)  | NO   |      | NULL    |       |

| CYCLE           | tinyint(0)   | NO   |      | NULL    |       |

11 rows in set (0.00 sec)

Create a sequence test.seq and query the next value of the sequence:

CREATE SEQUENCE test.seq;
SELECT NEXTVAL(test.seq);
SELECT * FROM sequences\G

The output is as follows:

+-------------------+
| NEXTVAL(test.seq) |
+-------------------+
|                 1 |
+-------------------+
1 row in set (0.01 sec)

View all sequences:

SELECT * FROM SEQUENCES\G

The output is as follows:
