Currently, MySQL does not provide any command to rename an existing database. However, you can rename the existing database through some ways. You can choose any of the following ways to rename a database in MySQL.

• If you have access to the directory where MySQL stores its databases. As per default MySQL installations, this is usually in the data directory under the directory where MySQL was installed. Locate the name of required database under the data directory and rename it as desired. Note: You must stop MySQL Server before renaming the database and may restart it after this operation. In this case, you may also grant permissions again on the renamed database.

• Another way that seems safest, is to use mysqldump utility to back up the old database. Create a new database with desired name, then restore the dumped database under this database using the mysql utility. Finally, use the DROP DATABASE old_database_name; command to get rid of the old database.
