Create 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.
Example
Here is a simple example to create a database called TUTORIALS −
[root@host]# mysqladmin -u root -p create TUTORIALS Enter password:******
This will create a MySQL database called TUTORIALS.
Create a Database using PHP Script
PHP uses mysqp query() or 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
$mysqp→query($sql,$resultmode)
| Sr.No. | Parameter & Description |
|---|---|
| 1 | $sql Required - SQL query to create a MySQL database. |
| 2 | $resultmode Optional - Either the constant MYSQLI_USE_RESULT or MYSQLI_STORE_RESULT depending on the desired behavior. By default, MYSQLI_STORE_RESULT is used. |
Example
Try the following example to create a database −
Copy and paste the following example as mysql_example.php −
<html>
<head><title>Creating MySQL Database</title></head>
<body>
<?php
$dbhost = localhost ;
$dbuser = root ;
$dbpass = root@123 ;
$mysqp = new mysqp($dbhost, $dbuser, $dbpass);
if($mysqp→connect_errno ) {
printf("Connect failed: %s<br />", $mysqp→connect_error);
exit();
}
printf( Connected successfully.<br /> );
if ($mysqp→query("CREATE DATABASE TUTORIALS")) {
printf("Database TUTORIALS created successfully.<br />");
}
if ($mysqp→errno) {
printf("Could not create database: %s<br />", $mysqp→error);
}
$mysqp→close();
?>
</body>
</html>
Output
Access the mysql_example.php deployed on apache web server and verify the output.
Connected successfully. Database TUTORIALS created successfully.Advertisements
