Autoincrement is a function that operates with record numbers. It automatically generates a new record number increased by 1.

It can be used for various purposes, such as for registering tasks for further processing and statistical purposes.

To create an autoincrement, the following criteria must be met:

  • The object for which you are configuring an autoincrement must have a field that should be incremented.
  • The field should be of String type. These fields are usually named Number.

If your table does not have this field, you can create it. Refer to the Create Columns article for more information.

The autoincrement settings are stored in the Number (sys_number) table

Description

Prefix+Specify at least three Latin letters that will be added at the beginning of every record number in this table.
Maximum digits+Define the maximum number of digits after the prefix.
Start value+Specify the initial value of the sequence. The default value is 1. 

Example

You just created a sequence, filled in the fields in the following way:

Field

Type

Value

PrefixStringABC

Maximum digits

Small Integer

6

Start Value

Integer

22

The first record number will be ABC000022, and the numbers of the subsequent records will be ABC000023, ABC000024, and so on.

If the value of the Start value changes, and it is greater than the current value of the sequence, the previous sequence will be saved, and the new sequence will be set to a new starting value.

  • If you create a record in the Record Number (sys_number) table, a sequence is created.
  • If you delete a record in the Record Number (sys_number) table, the sequence is deleted.
