Drupal 6 i18n taxonomy terms source from database.

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->condition('i18n.type', 'term');
    $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');
    $query->addField('lt', 'translation');
