   @zhaoyongjie 
   ```
   SELECT DATE(page_visit_at) AS __timestamp,
          count(DISTINCT session_id) AS `COUNT_DISTINCT(session_id)`
   FROM `ray-test`.user_behavior_record
   WHERE page_visit_at >= '2021-06-08 00:00:00.000000'
     AND page_visit_at < '2021-06-23 00:00:00.000000'
     AND ((code_project = '中文'))
   GROUP BY DATE(page_visit_at)
   LIMIT 500;
   ```
   
   it works well with mysql woekbench, but not work well with superset.
   when I change "中文" to "abc", then no error happen.
