Check out the below steps to rename a db in MySQL from the command line:

Step 1: Access the Command Line Interface

Open up your desired command line interface, like Terminal (Mac/Linux) or Command Prompt (Windows). Ensure that you have administrative privileges to execute commands.

Step 2: Connect to MySQL

Enter the command to connect to the MySQL server using your credentials. For example:

mysql -u <username> -p

In place of <username> type your MySQL username and press Enter. You will be asked to type in your password. Once authenticated, you will be in the MySQL command line interface.

Step 3: Choose the Database 

Select the database you want to rename by executing the following command:

USE current_database_name;

Replace current_database_name with the database name you wish to rename.

Step 4: Rename the Database 

Execute the command to rename the database:

ALTER DATABASE current_database_name RENAME TO new_database_name;

Replace current_database_name with the current name of the database and new_database_name with the desired new name.

Step 5: Verify the Renamed Database 

To confirm the successful renaming of the database, execute the following command:

SHOW DATABASES;

This command will present you with a list of every database on the MySQL server, incorporating the renamed database.

Step 6: Update Application Configurations 

If your application interacts with the renamed database, ensure that you update the necessary configurations to reflect the new database name. This step is crucial for maintaining proper functionality.

Step 7: Test the Renamed Database 

Thoroughly test your application to ensure that it works seamlessly with the renamed database. Check for any errors or issues and verify that all database operations are functioning correctly.

By following these steps, you can successfully rename a MySQL database from the command line. It is important to proceed with care, generate backups, and meticulously test your application to guarantee a seamless transition.

RENAME TABLE current_table_name TO new_table_name;

Replace current_table_name with the current name of the table and new_table_name with the desired new name.

Step 4: Verify the Renamed Table 

To confirm the successful renaming of the table, execute the following command:

SHOW TABLES;

This command will present you with a list of all the database tables, incorporating the renamed table.

Step 5: Update Application Code or Queries 

If your application interacts with the renamed table, ensure that you update the relevant code or queries to reflect the new table name. This step is essential to maintain the functionality of your application.

Step 6: Test the Renamed Table 

Thoroughly test your application to ensure that it operates smoothly with the renamed table. Check for any errors or issues and verify that all database operations related to the table are functioning correctly.

Step 7: Update Foreign Key Constraints (if applicable)
