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:
Parameter | Description |
sql | This required parameter consists of the SQL query needed to perform the operation. |
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(! $retval ) { die('Could not create database: ' . mysql_error()); } echo "Database PRODUCTS created successfully\n"; mysql_close($conn); ?> </body> </html>
On successful creation, you will see the following output:
mysql> Database PRODUCTS created successfully mysql> SHOW DATABASES; +--------------------+ | Database | +--------------------+ | PRODUCTS | +--------------------+
