How do I quickly rename a MySQL database (change schema name)?

Question

The MySQL manual at MySQL covers this.

Usually I just dump the database and reimport it with a new name. This is not an option for very big databases. Apparently

Answer 1

Emulating the missing RENAME DATABASE command in MySQL:

1. Create a new database

2. Create the rename queries with:

   SELECT CONCAT('RENAME TABLE ',table_schema,'.',table_name,
       ' TO ','new_schema.',table_name,';')
   FROM information_schema.TABLES
   WHERE table_schema LIKE 'old_schema';
   

3. Run that output

4. Delete old database
