Why Is My Python MySQL Insert Not Working?

Python MySQL Insert Not Functioning

When attempting to insert records into a MySQL database using the Python MySQL API, you may encounter issues with the data failing to persist. Understanding the underlying cause is crucial to resolve this problem effectively.

In the example provided, the connection and database structure appear to be properly configured. However, the missing step that prevents successful insertion is the lack of the db.commit() statement before closing the connection.

The db.commit() method is responsible for persisting all pending changes made to the database during the session. Without invoking this method, any modifications performed, such as insertions, updates, or deletions, will be lost when the connection is closed.

To fix this issue, add the following line before db.close():

<code class="python">db.commit()</code>

This will ensure that the changes made by the cursor.execute statement are committed to the database, allowing the inserted record to be visible and persistent.
