Code

public function query() {
    // Ideally, the query would return rows for each language for each menu link
    // with the translations for both the title and description or just the
    // title 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 title or description. The
    // method prepareRow() is then used to obtain the translation for the other
    // property.
    // The query starts with the same query as menu_link.
    $query = parent::query();
    // Add in the property, which is either title or description. Cast the mlid
    // to text so PostgreSQL can make the join.
    $query->leftJoin(static::I18N_STRING_TABLE, 'i18n', 'CAST(ml.mlid 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');
    $query->addField('lt', 'translation');
    return $query;
