gianm commented on issue #6108: more examples needed for druid sql URL: https://github.com/apache/incubator-druid/issues/6108#issuecomment-410796733 > @gianm regarding 4. is the behavior of native queries (topn, timeseries, groupby) the same as sql for this case? in that will they omit 10-11 from the results too? topN and groupBy will; for timeseries it depends on the skipEmptyBuckets setting.

Maybe four queries: one that plans to a scan, one that plans to a timeseries, one that plans to a topN, and one that plans to a groupBy? This is an automated message from the Apache Git Service.

(4) adheres to standard SQL: result rows are only emitted where there is actual data. So there would be no row for 10am–11am. This is an automated message from the Apache Git Service.

gianm commented on issue #6108: more examples needed for druid sql URL: https://github.com/apache/incubator-druid/issues/6108#issuecomment-410543659 Hi @pdeva, the answers to your questions are, 1. A time filter looks like `__time >= TIMESTAMP '2000-01-01 00:00:00' AND __time < TIMESTAMP '2000-01-02 00:00:00'`. 2. If you group by a `TIME_FLOOR` function, that's like specifying granularity. 3. Not sure what you mean by this? 4. Not sure what you mean by this? 5. They are undocumented, but they won't be for long. http://druid.io/docs/latest/misc/math-expr.html might help you understand what they're doing. I agree an examples section would be nice; @jon-wei was working on some new tutorials for querying, maybe he can chime in with whether he had planned on adding SQL examples.
