> Hi,
> while I am trying to upgrade an application's database from MySQL to IoTDB, a
> new operator in the SELECT statment is needed:
> MySQL:
> SELECT * FROM STATION_TABLE WHERE observationTime = '2016-11-30 10:00:00' AND
> pressure IN (100,1000,150,200,250,300,400,500,700,850,925);
> Using the SQL, if a station has data that pressure in such range, the
> station's data will be returned.
> Therefore, we need an "IN" operator in the WHERE clause, like:
> SELECT * FROM root.station.* where time = 2016-11-30 10:00:00 and pressure
> IN (100,1000,150,200,250,300,400,500,700,850,925) group by device;
>
