To rename a MySQL database, you can use the RENAME DATABASE statement. Here are the steps to rename a MySQL database:

  1. Make sure that no users are currently using the database that needs to be renamed. You can use the following command to view the users currently connected to the database:
SHOW PROCESSLIST;

Please wait for the users to disconnect from the database or manually disconnect them.

  1. Use the following syntax to rename the database:
RENAME DATABASE old_db_name TO new_db_name;

For example, to rename a database named “old_db” to “new_db”, you can execute the following command:

RENAME DATABASE old_db TO new_db;

Please note that the RENAME DATABASE statement is not a common operation in MySQL databases, so before executing this operation, please make sure that you have backed up the database just in case.

In addition, you can achieve the effect of renaming a database by exporting the data from the old database and creating a new one.
