MariaDB – Drop Database

MariaDB – Drop Database

Creation or deletion of databases in MariaDB requires privileges, typically, only given to root users or admins. Under these accounts, you have two options for deleting a database: the mysqladmin binary and a PHP script.

Note that deleted databases are irrecoverable, so exercise care in performing this operation. Furthermore, PHP scripts used for deletion do not prompt you with a confirmation before the deletion.

mysqladmin binary

The following example demonstrates how to use the mysqladmin binary to delete an existing database −

[root@host]# mysqladmin -u root -p drop PRODUCTS
Enter password:******
ERROR 1008 (HY000): Can't drop database 'PRODUCTS'; database doesn't exist

PHP Drop Database Script

PHP employs the mysql_query function in deleting MariaDB databases. The function uses two parameters, one optional, and returns either a value of “true” when successful, or “false” when not.


Review the following drop database script syntax −

bool mysql_query( sql, connection );

The description of the parameters is given below −

S.No Parameter & Description
1 sql

This required parameter consists of the SQL query needed to perform the operation.

2 connection

When not specified, this optional parameter uses the most recent connection used.

Try the following example code for deleting a database −

      <title>Delete a MariaDB Database</title>

         $dbhost = 'localhost:3036';
         $dbuser = 'root';
         $dbpass = 'rootpassword';
         $conn = mysql_connect($dbhost, $dbuser, $dbpass);
         if(! $conn ) {
            die('Could not connect: ' . mysql_error());
         echo 'Connected successfully<br />';
         $sql = 'DROP DATABASE PRODUCTS';
         $retval = mysql_query( $sql, $conn );
         if(! $retval ){
            die('Could not delete database: ' . mysql_error());

         echo "Database PRODUCTS deleted successfullyn";

On successful deletion, you will see the following output −

mysql> Database PRODUCTS deleted successfully
