Synopsis

To rename a database, the user must be a member of the admin role or must have the CREATEDB parameter set.

Parameter	Description
`name`	The first instance of `name` is the current name of the database. The second instance is the new name for the database. The new name must be unique and follow these identifier rules. You cannot rename a database if it is set as the current database or if `sql_safe_updates = true`.

This schema change statement is registered as a job. You can view long-running jobs with SHOW JOBS.

It is not possible to rename a database if the database is referenced by a view. For more details, see View Dependencies.
