Use dbquery to run a query in the Drupal database.

The first parameter is the query as a text string.  Then a variable number of parameters are permitted, each being a variable that is substituted into the query.  This variable substitution is necessary to avoid SQL injection attacks.

For example:

dbquery("SELECT * FROM node INNERJOIN content_type_profile ON node.nid = content_type_profile.nid WHERE node.nid = %d", $nid);
$start = time();
$query = "SELECT * FROM node INNERJOIN content_type_profile ON node.nid = content_type_profile.nid WHERE node.nid = %d";
$result = dbquery($query, $nid);
//dpm($query); //Used for debugging
//dpm($result); //Used for debugging
$duration = time() - $start;
watchdog('gs_custom', 'Search query took '. $duration .'ms');
if ($result) {
      while ($row = db_fetch_object($result)) {
        $status = $row->status;
        // Do something...
      }
}


Available Substitution Placeholder:

%s => String
%d => Integer
%b => Binary
%f => Float
%% => Insert a literal %
