How do I rename a MySQL database (change schema name)?

Renaming a MySQL database (also known as changing the schema name) involves creating a new database with the desired name, transferring the data and objects from the old database to the new one, and then dropping the old database. Here's an example of how you can do this:

Please note: Renaming a database can be a critical operation, and you should perform backups before making any changes to your database. Make sure you have appropriate permissions and understand the potential risks before proceeding.

    Backup your database: Before making any changes, it's important to have a backup of your database.

    Create a new database with the desired name:

    sql

CREATE DATABASE new_database_name;

Transfer data and objects from the old database to the new one:

    Tables: You can use mysqldump to export the data from the old database and then import it into the new database.

    bash

    mysqldump -u username -p old_database_name > backup.sql
    mysql -u username -p new_database_name < backup.sql

    Views, stored procedures, etc.: These will need to be recreated in the new database.

Update application configurations: If your application references the old database name, you'll need to update its configurations to use the new database name.

Test your new database: Make sure everything works as expected with the new database.

Drop the old database (optional): Once you're confident that the new database is working correctly, you can drop the old database.

sql

    DROP DATABASE old_database_name;

Remember, this process involves multiple steps and careful consideration. Make sure to test thoroughly in a controlled environment before performing this operation on a production database.
