Combining UNSIGNED BIGINT and AUTO_INCREMENT in MySQL

When we combine unsigned bigint and auto_increment in MySQL, we get a column that has the following features:

Functions as a Perfect Primary Key: Being AUTO_INCREMENT and UNSIGNED ensures that every row has a distinct, growing identifier, which makes it a good option for a primary key.

Manages Huge Datasets: Huge datasets are handled using the BIGINT data type, which has enough storage capacity to hold a huge number of rows.

Simplifies Record Insertion: When inserting a record, we don’t have to specifically provide a value for this column. MySQL handles the process of automatically creating a unique ID.

Benefits

1. By removing the need to manually allocate IDs, AUTO_INCREMENT saves the time and effort.

2. Duplicate entry is avoided and data processing within and between tables is made easier by the assured uniqueness of IDs.

3. BIGINT gives us plenty of space to store a large number of records, thus the table will be scalable in the future.

An Example

Here, the id column takes on the role of the primary key, ensuring that every user has a unique, non-repeating identity. MySQL will automatically create the next available ID (beginning with 1) for that record whenever we insert a new user.
