MySQL Query Errors

I'm testing a simple SQL query from my Products table, in the Navigator_Data database, whihc is the second database to my Drupal site.

I put this in a Block (PHP code text format), and get this error.

<?php
  $navigator_array = array(
      'database' => 'navigator_data',
      'username' => 'sandshakimi', 
      'password' => 'XXX', 
      'host' => 'localhost', 
      'driver' => 'mysql', 
  );
  Database::addConnectionInfo('PRODUCT', 'default', $navigator_data);
  db_set_active('PRODUCT');
  $result = mysql_query('SELECT * FROM `PRODUCT` ');
  db_set_active(); // without the paramater means set back to the default for the site

?>

Those functions must come from Drupal because they are not PHP functions.  Except... mysql_query() is probably Not the method being used in Drupal.  They are probably using the 'mysqli' driver which is different than the 'mysql' driver.  Look at the Drupal code to find their method of doing a query.

I have not verified this, but at first glance it looks like it's on target.

I think db_query() may be the Drupal wrapper for PHP mysql_query().  The problem appears to be caused by missing or incorrect authentication credentials, or missing permissions in the MySQL database.

You should be defining your database connection info in your settings.php file. It should look something like this:
$databases['nav_data']['default'] = array(
    'database' => 'navigator_data',
    'username' => 'sandshakimi',
    'password' => 'XXX',
    'host' => 'localhost',
    'driver' => 'mysql',
);

Then in your code, access it this way:
$nav_data = Database::getConnection('default', 'nav_data');
$result = $nav_data->query('SELECT * FROM `PRODUCT` ');

Open in new window


or this way:
db_set_active('nav_data');
$result = db_query('SELECT * FROM `PRODUCT` ');
db_set_active();
