Dropping MySQL Database

# Drop MySQL Database ## Drop a Database using mysqladmin You would need special privileges to create or to delete a MySQL database. So, assuming you have access to the root user, you can create any database using the mysql **mysqladmin** binary. Be careful while deleting any database because you will lose your all the data available in your database. Here is an example to delete a database(TUTORIALS) created in the previous chapter − ``` [root@host]# mysqladmin -u root -p drop TUTORIALS Enter password:****** ``` This will give you a warning and it will confirm if you really want to delete this database or not. ``` Dropping the database is potentially a very bad thing to do. Any data stored in the database will be destroyed. Do you really want to drop the 'TUTORIALS' database [y/N] y Database "TUTORIALS" dropped ``` ## Drop Database using PHP Script PHP uses **mysqli query()** or **mysql\_query()** function to drop a MySQL database.
