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 | | | CACHE | tinyint(0) | NO | | NULL | | | CACHE_VALUE | bigint(21) | YES | | NULL | | | CYCLE | tinyint(0) | NO | | NULL | | | INCREMENT | bigint(21) | NO | | NULL | | | MAX_VALUE | bigint(21) | YES | | NULL | | | MIN_VALUE | bigint(21) | YES | | NULL | | | START | bigint(21) | YES | | NULL | | | COMMENT | varchar(64) | YES | | 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:

*************************** 1. row *************************** TABLE_CATALOG: def SEQUENCE_SCHEMA: test SEQUENCE_NAME: seq CACHE: 1 CACHE_VALUE: 1000 CYCLE: 0 INCREMENT: 1 MAX_VALUE: 9223372036854775806 MIN_VALUE: 1 START: 1 COMMENT: 1 row in set (0.00 sec)
