What are the advantages of using auto_increment in MySQL for generating unique identifiers?
When working with databases, it is often necessary to generate unique identifiers for records. One way to achieve this in MySQL is by using the auto_increment attribute on a column. This attribute automatically generates a unique value for each new record inserted into the table, simplifying the process of creating unique identifiers.
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(50)
);
INSERT INTO users (name) VALUES ('John');
INSERT INTO users (name) VALUES ('Jane');
