How Can I Efficiently Perform Bulk Data Insertion in MySQL?

Optimizing MySQL Bulk Data Insertion

Handling large-scale data insertion into MySQL demands a high-performance approach. While iterative insertion using loops might seem simple, it's significantly less efficient. MySQL offers a superior method for bulk inserts.

The recommended technique, as outlined in the MySQL documentation, involves using a single INSERT statement with multiple VALUES clauses. This allows for the simultaneous insertion of numerous rows. Each row's data is enclosed in parentheses and separated by commas, creating a list of row values.

For example, to add three rows to a table named tbl_name with columns a, b, and c, the following query would be used:

<code class="language-sql">INSERT INTO tbl_name (a, b, c)
VALUES (1, 2, 3), (4, 5, 6), (7, 8, 9);</code>

This method dramatically outperforms individual row insertions, reducing database overhead and minimizing server communication. By employing this multi-VALUES INSERT statement, developers can achieve substantial improvements in bulk data insertion speed and efficiency within their applications.
