Drop MySQL Database

In this article, we are going to learn all about How to drop MySQL databases using the MySQL DROP DATABASE statement. In the previous tutorial, we have seen all about, how to create a MySQL database.

MySQL DROP Database Statement

MySQL provides a DROP DATABASE statement to delete the data database from the MySQL server. DROP DATABASE drops all the databases from the MySQL server Therefore, you need to be very careful when you are going to work with the MySQL DROP DATABASE statement.

Syntax

The syntax of MySQL DROP DATABASE statement is:-

DROP DATABASE [IF EXIST] database_name;

If you try to delete a database that does not exist, MySQL cause an error. To prevent an error from occurring if you deleting the non-existing database, you have to use the IF EXIST statement before the database name.

The DROP DATABASE statement returns the number of tables deleted.

You can use DROP SCHEMA instead of DROP DATABASE because SCHEMA is the synonym of DATABASE.
You can see the following syntax.

DROP SCHEMA [IF EXIST] database_name;

There are two ways to drop databases from the MySQL server.

1. Using MySQL Client tool.
2. Using Workbench

MySQL DROP DATABASE using mysql client tool
