> Hey @zhaojiandong,

> What result _do_ you get when you run this query? And what do you get if you add "EXPLAIN PLAN FOR" to the front of it?
For example, the inner SQL
```
SELECT
TIME_FLOOR(__time, 'PT1M') as t,
host,
sum(sum_value) as v
FROM druid_metric_default
```
We got:
| t | host | v |
| :------| :------ | :------ |
| 2018-11-22T10:00:00.000Z | druid-host1 | 100 |
| 2018-11-22T10:00:00.000Z | druid-host2 | 10 |
| 2018-11-22T10:01:00.000Z | druid-host1 |150 |
| 2018-11-22T10:01:00.000Z | druid-host2 | 12 |
We expect to get when run the whole sql：
| t | tps_host1 | tps_host2 |
| :------| :------ | :------ |
| 2018-11-22T10:00:00.000Z | 100 | 10 |
| 2018-11-22T10:01:00.000Z | 150 | 12 |
Actually We get:
| t | tps_host1 | tps_host2 |
| :------| :------ | :------ |
|2018-11-22T10:00:00.000Z | 0 | 0 |
|2018-11-22T10:01:00.000Z | 0 | 0 |
