   I have the latest libraries, snowflake-connector-python-1.7.9 and snowflake-sqlalchemy-1.1.11. When I run the query in the Snowflake web UI, it returns the columns in all caps. `__TIMESTAMP` is one of them. I have a fix for this, so I will make a pull request for 0.31. The bug was not reproducible on master. 
   
   
   The query generated is
   ```
   SELECT DATE_TRUNC('DAY', CHECK_IN_TIME) AS "__timestamp",
          COUNT(DISTINCT "INSTANCE3") AS "COUNT_DISTINCT(INSTANCE3)"
   FROM
     (SELECT *
      FROM emory.public.raw_er) AS expr_qry
   WHERE "CHECK_IN_TIME" >= '1919-03-27 00:00:00'
   GROUP BY DATE_TRUNC('DAY', CHECK_IN_TIME)
   ORDER BY "COUNT_DISTINCT(INSTANCE3)" DESC
   LIMIT 1000;
   ```
