zhaojiandong opened a new issue #6651: Case when cannot work on nested sql
URL: https://github.com/apache/incubator-druid/issues/6651
 
 
   My SQL is as follows, I use case..when in outer sql, but  cannot get "value"
   ```
   SELECT 
   t, 
   sum(CASE host WHEN 'druid-host1' then value ELSE 1 END) as "tps_host1",
   sum(CASE host WHEN 'druid-host2' then value ELSE 1 END) as "tps_host2"
   FROM(
   SELECT
       TIME_FLOOR(__time, 'PT1M') as t,
       host,
       sum(sum_value) as value
   FROM druid_metric_default
   WHERE "__time" >= '2018-11-21 16:30:00+0800'
   AND metric='ingest/events/processed'
   GROUP BY TIME_FLOOR(__time, 'PT1M'),host
   )
   GROUP by t
   ```
