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 creating a database − the mysqladmin binary and a PHP script.
mysqladmin binary
The following example demonstrates the use of the mysqladmin binary in creating a database with the name Products −
[root@host]# mysqladmin -u root -p create PRODUCTS Enter password:******
PHP Create Database Script
PHP employs the mysql_query function in creating a MariaDB database. The function uses two parameters, one optional, and returns either a value of “true” when successful, or “false” when not.
Syntax
Review the following create 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 creating 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(! $retval ) {
die(''Could not create database: '' . mysql_error());
}
echo "Database PRODUCTS created successfullyn";
mysql_close($conn);
?>
</body>
</html>
On successful deletion, you will see the following output −
mysql> Database PRODUCTS created successfully mysql> SHOW DATABASES; +-----------------------+ | Database | +-----------------------+ | PRODUCTS | +-----------------------+
