MySQL DROP DATABASE Statement


Sometimes, you need to remove a database when you don’t need it anymore. But before making this decision, do make sure that you don’t need data stored in different tables of the database. This is because, when you drop a database, all its tables also get removed along with the database.


To remove a database, you need to issue a command with following syntax.

Syntax :

DROP DATABASE  <database name> ;

Note: 

Be careful before dropping a database. Deleting a database will result in loss of complete information stored in the database!

DROP DATABASE Example

That is, to drop a database namely myDB, you have to write the code given below :

DROP DATABASE  myDB ;

Now that you know about how to create and use databases, you can move on to creating tables and adding data to them.

Note: 

Be careful before dropping a database. Deleting a database will result in loss of complete information stored in the database!

MySQL DROP DATABASE IF EXISTS

MySQL DROP DATABASE IF EXISTS will first check for existence of database. If it exists, then it will delete the database.

DROP DATABASE IF EXISTS database_name;

Example :

DROP DATABASE IF EXISTS mariaDB;

The above query will first check for existence of database mariaDB. If it exists, then it will delete the database mariaDB.
