您好，我有查询，其中我已使用select语句编写了更新语句。但是不幸的是，子查询返回错误会返回1行以上的错误。我知道错误即将到来。但我不知道相同的解决方案。谢谢。这是查询：

UPDATE adsetest.dashboard_widget_users
SET configuration=
  (SELECT DISTINCT ad_news_texte.headline
   FROM autodo.ad_news_texte
   INNER JOIN autodo.ad_news_oe
     ON ad_news_texte.news_id = ad_news_oe.id_ad_news
   INNER JOIN autodo.ad_news
     ON ad_news_oe.id_ad_news = ad_news.id
   WHERE ad_news.datum_archiv BETWEEN
     curdate() - INTERVAL DAYOFWEEK(curdate()) + 28 DAY AND curdate())
WHERE dsnr_yw_user = 1 AND dsnr_dashboard_widget = 1
