SQL - ALTER SEQUENCE

Changes the sequence. Using this parameter you can change all sequence options, except for the sequence type.

This feature was introduced in version 2.2.

Syntax

ALTER SEQUENCE <sequence> [START <start-point>] [INCREMENT <increment>] [CACHE <cache>] [CYCLE TRUE|FALSE] [LIMIT <limit_value>] [ASC|DESC]
  • <sequence> Defines the sequence you want to change.
  • START Defines the initial sequence value.
  • INCREMENT Defines the value to increment when it calls .next().
  • CACHE Defines the number of values to cache, in the event that the sequence is of the type CACHED.
  • CYCLE Defines if sequence will restart from START value after LIMIT value reached. Default value is FALSE.
  • LIMIT Defines limit value sequence can reach. After limit value is reached cyclic sequences will restart from START value, while non cyclic sequences will throw message that limit is reached.
  • ASC | DESC Defines order of the sequence. ASC defines that next sequence value will be currentValue + incrementValue, while DESC defines that next sequence value will be currentValue - incrementValue (assuming that limit is not reached). Default value is ASC.
  • NOLIMIT Cancel previously defined LIMIT value

Examples

  • Alter a sequence, resetting the start value to 1000:

    orientdb> ALTER SEQUENCE idseq START 1000 CYCLE TRUE
