MySQL Drop Database

We can drop/delete/remove a MySQL database quickly with the MySQL DROP DATABASE command. It will delete the database along with all the tables, indexes, and constraints permanently.

Therefore, we should have to be very careful while removing the database in MySQL because we will lose all the data available in the database. If the database is not available in the MySQL server, the DROP DATABASE statement throws an error.

We can drop an existing database in MySQL by using the DROP DATABASE statement with the below syntax:

 DROP DATABASE [IF EXISTS] database_name;
