查询语句中有一处错误，缺少了一个右括号。以下是修正后的查询语句：

SELECT t2.city_name, COUNT(*) AS count
FROM (
  SELECT cuid
  FROM (
    SELECT cuid, ROW_NUMBER() OVER (PARTITION BY cuid ORDER BY cuid) AS rn
    FROM map_huiyan_short_stay
    WHERE loc_x > 12993523 AND loc_x < 13012467 AND loc_y > 4773079 AND loc_y < 4789463 AND event_day = 20230605
  ) t1
  WHERE rn = 1
) t1
JOIN (
  SELECT cuid, city_name
  FROM map_huiyan_long_stay_with_area
  WHERE event_day = 20230605 AND event_type = 'home' AND event_os = 'android'
) t2 ON t1.cuid = t2.cuid
GROUP BY t2.city_name;

请注意，你需要将 `map_huiyan_short_stay` 和 `map_huiyan_long_stay_with_area` 替换为你实际的表名。另外，确保查询条件和连接条件与你的需求匹配。

请执行修改后的查询语句并检查是否仍然存在其他错误。
