Creating or deleting a database in MariaDB requires permissions that are typically granted only to root users or administrators. U nder these accounts, you have two options to create a database - mysqladmin binary and PHP script.
The following example shows how to create a database called Publics using mysqladmin scripts -
[root@host]# mysqladmin -u root -p create PRODUCTS Enter password:******
PHP uses a number of functions when creating mysql_query database. T he function uses two arguments, one optional, and returns the value "true" if successful, otherwise "false".
See below Create a database Script syntax -
bool mysql_query( sql, connection );
The parameters are described below -
| S.No | Parameters and descriptions |
|---|---|
| 1 |
Sql This parameter must consist of the SQL query to be performed. |
| 2 |
connection
When not specified, this optional parameter uses the most recently used connection. |
Try the following sample code to create a database -
<html>
<head>
<title>Create a MariaDB Database</title>
</head>
<body>
<?php
$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 = 'CREATE DATABASE PRODUCTS';
$retval = mysql_query( $sql, $conn );
if(! $retval ) {
die('Could not create database: ' . mysql_error());
}
echo "Database PRODUCTS created successfully
";
mysql_close($conn);
?>
</body>
</html>
After successful deletion, you will see the following output -
mysql> Database PRODUCTS created successfully mysql> SHOW DATABASES; +-----------------------+ | Database | +-----------------------+ | PRODUCTS | +-----------------------+
