[GitHub] [superset] Z0ltrix opened a new issue #18869: Drill Time Range Filter not usable
Z0ltrix opened a new issue #18869:
URL: https://github.com/apache/superset/issues/18869
we have a problem with our superset -> drill connection with time range filters.
When we filter a dashboard by time range (last week, month, etc.) i get an
```
SYSTEM ERROR: ClassCastException: org.apache.drill.exec.expr.holders.NullableTimeStampHolder cannot be cast to org.apache.drill.exec.expr.holders.TimeStampHolder
```
from drill.
#### How to reproduce the bug
1. Create a Dataset based on Drill
2. Create a Filter Box
3. Create a Dashboard
4. Make sure everything works
5. Aktivate a Time Range Filter on the Filter Box
6. Everything fails with the error in Drill
### Expected results
Superset should send the following filter:
```
WHERE `startTime` >= TIMESTAMP '2022-02-14 00:00:00.000000'
AND `startTime` < TIMESTAMP '2022-02-21 00:00:00.000000'
ORDER BY `startTime` DESC
```
### Actual results
Superset sends the following to drill:
```
WHERE `startTime` >= '2022-02-14 00:00:00.000000'
AND `startTime` < '2022-02-21 00:00:00.000000'
ORDER BY `startTime` DESC
```
#### Screenshots
### Environment
(please complete the following information):
- browser type and version: Chrome Version 98.0.4758.102
- superset version: 1.3.0
- python version: 3.8.0

Thanks for reporting @Z0ltrix - can you check what the datatype of `startDate` is in your dataset (=the native column type in the physical table)?

Hi, both of the syntaxes exhibited by @Z0ltrix above should work with a TIMESTAMP column but due to a bug affecting an optional Drill feature (which @Z0ltrix had enabled) the error shown is encountered in one case. We're going to rework the Drill feature so that this problem goes away and Superset's SQL syntax will not cause any trouble.
https://issues.apache.org/jira/browse/DRILL-8157
The immediate workaround for anyone affected by this is ``SET `functions.cast_empty_string_to_null` = false;``

`select typeof(startTime) from dfs.path.dataset limit 1` returns TIMESTAMP
in Superset this is shown as DATETIME
