database related problem

[eluser]madhobi[/eluser]
if I autoload the library in config/autoload.php file it gives the following error.
"Unable to connect to your database server using the provided settings.

Filename: D:\wamp\www\community\system\database\DB_driver.php

Line Number: 124"

This is my first php code and also first work with CI. Please anyone can help me.

Check your database setting, database.php under './application/config/'!
Make sure every input (database name, database username and password) valid.

And also make sure that you create the database first!

yes, database name is correct. But I did not mention any username, password. In normal php file I can access the database. Is username and password mandatory?

If all else fails then dab this debug test code onto the end of:

// ./application/config/database.php

Code:

// /*
  echo '<pre>';
    print_r($db['default']);
  echo '</pre><br />';

  echo 'Connecting to database: ' .$db['default']['database'];

  $dbh=mysql_connect
  (
    $db['default']['hostname'],
    $db['default']['username'],
    $db['default']['password'])
    or die('Cannot connect to the database because: ' . mysql_error()
  );
  
  mysql_select_db ($db['default']['database']);
    
  echo '<br />Connected OK:';
    
// */

username and password would be the same that you used to create the database!

You can set autoinit to FALSE in config/database.php and the connection won't be made untill you call $this->db->initialize(). You would still need to set the username and password in config/database.php, though.

I made the mistake by empty username and password.
