An auto-incremented key is a key (often used in a parent/foreign key constraint) that is generated automatically by a sequence number generator. The database provides the sequence generator, and generation/acquisition is wrapped in a transaction so that integrity can be preserved. Often, however, if a rollback is done, key values are lost, but this is not an issue in properly designed parent/foreign key relationships.

What is a auto field?
An auto field, often referred to as an "auto-increment" field, is a database column that automatically generates a unique sequential number for each new record inserted into a table. This feature is commonly used for primary keys to ensure that each record can be uniquely identified without requiring manual input.
