Question

I would like to connect to the database from a Drupal 7 module. Currently I only have the query I want to run which is:

$query = db_select('z_lists)
->fields('country')
->condition('value', $country, '=')
->execute()
->fetchAssoc();

What I can’t figure out is how to establish a connection to the default database.

Any help?

In Drupal7 there is function called db_query(). you can use that function to run your queries.
You can use below syntex

$var1 = 1;
$result = db_query('SELECT n.title FROM {node} n WHERE n.uid = :uid', array(':uid' => $var1));

$result will be stdClass object so you can use it in foreach loop.
