How to Delete a MySQL or MariaDB Database via Command Line

Step 1: Log into the MySQL Server

The following command allows logging in to the MySQL server from the command line as root. It specifies the root user with the -u flag and uses the -p flag to prompt for a password.

mysql -u root -p

Enter your current password to log in. You can change a password for MySQL via the command line also, if necessary.

Once complete, you reach a MySQL prompt.

mysql>

Step 2: Delete a Database in MySQL or MariaDB

Note: Removing a MySQL or MariaDB database cannot be undone. 

The following command deletes your database in MySQL. For this tutorial, the command removes the database named tutorial_database.

DROP DATABASE tutorial_database;

The following error appears only if a database with the name tutorial_database does not exist.

ERROR 1008 (HY000): Can't drop database 'tutorial_database'; database doesn't exist

A way to avoid seeing this error is using the following syntax, which removes the database only if it exists.

DROP DATABASE IF EXISTS tutorial_database;
