Code

function taxonomy_breadcrumb_node_get_lightest_term($nid) {

  // We only want the first row of the result--this is the lightest term of the
  // lightest vocab.  This query should be the same as the query found in
  // taxonomy_node_get_terms.
  $result = db_query(db_rewrite_sql('SELECT t.* FROM {term_node} r INNER JOIN {term_data} t ON r.tid = t.tid INNER JOIN {vocabulary} v ON t.vid = v.vid WHERE r.nid = %d ORDER BY v.weight, t.weight, t.name', 't', 'tid'), $nid);
  $term = db_fetch_object($result);

  // extract first row of query
  return $term;
