In MySQL, you can use the RENAME DATABASE statement to rename a database. The basic syntax for the RENAME DATABASE statement is as follows:

RENAME DATABASE old_database_name TO new_database_name;

Where old_database_name refers to the current name of the database to be renamed, and new_database_name is the new name it will be changed to.

However, it is important to note that the official MySQL documentation does not provide a direct way to rename a database. Therefore, there are a few considerations to keep in mind when using the RENAME DATABASE statement.

  1. The database that needs to be renamed must be in a closed state.
  2. Renaming a database is achieved by modifying the database file system, so for large databases, it may take some time and could potentially impact the database’s performance.
  3. In certain cases, special tools may be necessary to carry out the renaming process.

Therefore, before carrying out any renaming database operations, make sure you have made appropriate backups and carefully consider the impact on the performance of the database.
