Code

public function query() {

  // Ideally, the query would return rows for each language for each taxonomy
  // term with the translations for both the name and description or just the
  // name translation or just the description translation. That query quickly
  // became complex and would be difficult to maintain.
  // Therefore, build a query based on i18nstrings table where each row has
  // the translation for only one property, either name or description. The
  // method prepareRow() is then used to obtain the translation for the other
  // property.
  $query = parent::query();
  $query
    ->addField('td', 'language', 'td.language');

  // Add in the property, which is either name or description.
  // Cast td.tid as char for PostgreSQL compatibility.
  $query
    ->leftJoin('i18n_strings', 'i18n', 'CAST(td.tid AS CHAR(255)) = i18n.objectid');
  $query
    ->addField('i18n', 'lid');
  $query
    ->addField('i18n', 'property');

  // Add in the translation for the property.
  $query
    ->innerJoin('locales_target', 'lt', 'i18n.lid = lt.lid');
  $query
    ->addField('lt', 'language', 'lt.language');
