Why Are My MySQL Updates Not Being Saved in My Python Script?

Working Python MySQL Update Script

The provided script updates a MySQL database, but the modifications are not reflected in the table. To resolve this issue, the script needs to commit the changes to the database.

The script establishes a connection to the database using MySQLdb. Within a try block, a cursor is created, and an UPDATE statement is executed to set the CurrentState field to 1 for rows with RadioID 11. The cursor's rowcount is then printed to confirm the number of updated rows.

However, the missing step is the commit() method on the database connection object, dbb. This method is responsible for applying the changes made through the cursor to the database. Without calling commit(), the updates are only loaded into the MySQL server but not permanently saved.

To ensure the updates are applied, add the following line after executing the UPDATE statement:

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

This commit() statement will instruct the MySQL server to make the changes persistent in the database, ensuring that the CurrentState field is updated as intended.
