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.

Drop Database using PHP Script

bool mysql_query( sql, connection );
Sr.NoParameter & Description
1sql Required − SQL query to create or delete a MySQL database
2connection Optional − if not specified, then the last opened connection by mysql_connect will be used.


Try the following example to delete a database −

      <title>Deleting MySQL 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 TUTORIALS';
         $retval = mysql_query( $sql, $conn );
         if(! $retval ) {
            die('Could not delete database: ' . mysql_error());
         echo "Database TUTORIALS deleted successfully\n";

WARNING − While deleting a database using the PHP script, it does not prompt you for any confirmation. So be careful while deleting a MySQL database
