Abstract
A system that performs a database operation which involves accessing user-defined fields which are stored in a custom field table, wherein the user-defined fields are used to augment an existing table. During operation, the system performs the database operation which involves accessing the user defined fields. While accessing the user-defined fields, the system performs a mapping between the user-defined fields and custom fields in the custom field table, wherein each row in the custom field table includes a position field and multiple custom fields.
