Go Up to IBM DB2 for Linux, Unix, and Windows Object Editors

The Sequences Editor lets you manage cycle numbers, increments, the datatype, and other options for a sequence.

To edit a sequence

  1. Open an editor on the sequence. For details, see Opening an Object Editor.
  2. Use the following table as a guide to understanding and modifying the settings on the tabs of this editor:
Tab Settings and tasks

Definition

Lets you work with settings in the following categories:

Parameters

Increment By - Lets you specify the interval between sequence numbers. This integer value can be any positive or negative integer, but it cannot be 0. This value can have 28 or fewer digits. The absolute of this value must be less than the difference of MAXVALUE and MINVALUE. If this value is negative, then the sequence descends. If the increment is positive, then the sequence ascends. If you omit this clause, the interval defaults to 1. Minimum Value - Lets you specify the minimum value of the sequence. This integer value can have 28 or fewer digits. Maximum Value - Lets you specify the maximum value the sequence can generate. This integer value can have 28 or fewer digits.

Next Sequence Numbers

Lets you work with sequence cycle numbers.

Sequence Datatype

Lets you specify the datatype and width for the sequence.

Options

Lets you specify Cache Size, Cycle When Reach Max/Min, and Generate Numbers in Order (useful when you are using the sequence number as a timestamp) values.
