This module uses the sticky column of the node table to add weighting to nodes.

Code

function weight_uninstall() {

  // We need to unset any weighted nodes and reset sticky to normal values.
  $weight_node_types = variable_get('weight_node_types', array());
  if ($weight_node_types) {
    db_update('node')
      ->fields(array(
      'sticky' => 1,
    ))
      ->condition('sticky', 1, '>')
      ->condition('type', $weight_node_types, 'IN')
      ->execute();
    db_update('node')
      ->fields(array(
      'sticky' => 0,
    ))
      ->condition('sticky', 0, '<')
      ->condition('type', $weight_node_types, 'IN')
      ->execute();
  }

  // reset sticky values in taxonomy_index table.
  db_update('taxonomy_index')
    ->fields(array(
    'sticky' => 1,
  ))
    ->condition('sticky', 1, '>')
    ->execute();
  db_update('taxonomy_index')
    ->fields(array(
    'sticky' => 0,
  ))
    ->condition('sticky', 0, '<')
    ->execute();

  // reset taxonomy_index field to original type.
  $spec = array(
    'description' => 'Boolean indicating whether the node is sticky.',
    'type' => 'int',
    'not null' => FALSE,
    'default' => 0,
    'size' => 'tiny',
  );
  db_change_field('taxonomy_index', 'sticky', 'sticky', $spec);

  // Delete our variables.
