How has inserting data changed in recent MySQL versions?

In recent MySQL versions, inserting data has seen several enhancements that improve performance, flexibility, and usability. Notably, features such as the INSERT ... ON DUPLICATE KEY UPDATE syntax and the introduction of JSON support have made it easier to manage data integrity and work with semi-structured data.

Additionally, MySQL 8.0 introduced the ability to use the multi-row INSERT syntax more efficiently, which allows developers to add multiple rows in a single query. These enhancements help to reduce the number of round trips to the database and decrease overall execution time.

Example

$mysqli = new mysqli("localhost", "user", "password", "database"); // Insert multiple rows $mysqli->query("INSERT INTO users (name, email) VALUES ('Alice', 'alice@example.com'), ('Bob', 'bob@example.com')"); // Insert with ON DUPLICATE KEY UPDATE $mysqli->query("INSERT INTO users (id, name, email) VALUES (1, 'Alice', 'alice@example.com') ON DUPLICATE KEY UPDATE name='Alice Updated', email='alice_updated@example.com'"); // Close connection $mysqli->close();
