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. One of them, for example, is registering inquiries for their further processing and statistical purposes.
Autoincrement settings are stored in twotables:
The Number (sys_number) table contains the Maximum digits and the Prefix settings for the table;
The Autoincrement (sys_number_autoincrement) table stores the autoincrement setting related to the table.
For working correctly, records in both tables must be created. If the record in the Number (sys_number) table exists and the record in the Autoincrement (sys_number_autoincrement) table is not, then it will be created automatically, and the numbering will start with 1.
In order to create an autoincrement rule, the following criteria must be met: the object you are configuring an autoincrement for must have a field that should be incremented. It must have a String type, and generally, these fields are named as "Number".
If your table does not have this field, please create it: please refer to the Creating a Column article for more information.
