MYSQL ( Lesson No. IV ) ~ Tricks Tutorial

Create MySQL Database

CREATE DATABASE USING MYSQLADMIN:

You would need special privilege to create or to delete a MySQL database. So assuming you have access to root user, you can create any database using mysqladmin binary.

Example:

Here is a simple example to create database called TUTORIALS:

[root@host]# mysqladmin -u root -p create TUTORIALS
Enter password:******

This will create a MySQL database TUTORIALS.

CREATE DATABASE USING PHP SCRIPT:

PHP uses mysql_query function to create or delete a MySQL database. This function takes two parameters and returns TRUE on success or FALSE on failure.

Syntax:

bool mysql_query( sql, connection );

Parameter	Description
sql	Required - SQL query to create or delete a MySQL database
connection	Optional - if not specified then last opened connection by mysql_connect will be used.

Example:

Try out following example to create a database:

<html>
<head>
<title>Creating MySQL 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 TUTORIALS';
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
  die('Could not create database: ' . mysql_error());
}
echo "Database TUTORIALS created successfully\n";
mysql_close($conn);
?>
</body>
</html>
