3.2. Database CreationTo get started using MySQL, you need to create a database. First, let's take a look at the databases that come with a clean MySQL installation using the SHOW DATABASES command. Upon installation of MySQL 3.23.40, the following tables already exist: mysql> SHOW DATABASES; +----------+ | Database | +----------+ | mysql | | test | +----------+ 2 rows in set (0.37 sec) The first database, mysql, is MySQL's system database, which you will learn more about in Chapter 5. The second database, test, is a play database you can use to learn MySQL and run tests against. You may find other databases on your server if you are not dealing with a clean installation. For now, however, we want to create a new database to illustrate the use of the MySQL CREATE statement: CREATE DATABASE TEMPDB; and then to work with the new database TEMPDB: USE TEMPDB; Finally, you can delete that database by issuing the DROP DATABASE command: DROP DATABASE TEMPDB; You can create new objects using the CREATE statement and destroy things using the DROP statement, just as we used them here.
