Hi ,
I have complex file json file and I am able to query as below :
SELECT `t`.`results`.`_id` as `_id`,`t`.`results`.`Session` as
`Session`,`t`.`results`.`Gateway` as `Gateway`,`t`.`results`.`Device` as
`Device`,`t`.`results`.`Client` as `Client`,`t`.`results`.`Category` as
`Category`,
`t`.`results`.`LastUpdate` as `LastUpdate`,`t`.`results`.`Coordinates` as
`Coordinates_x`,`t`.`results`.`Start` as `Start`,`t`.`results`.`End` as
`End` FROM (SELECT FLATTEN(results) as `results` FROM
`tmp`.`default`.`./path/to/file.json`) `t`


_id
Session Gateway Device Client Category LastUpdate Coordinates_x Start End

5b0fa3bbf9490e0b080bb758
5b0fa3c40000001cdf003c53 02422d207f0b 2 0 0 1527751644
[[36.11,19.31,0],[38.51,9.5,12],[25.64,13.07,24]] 1527751620 1527751644
5b0fa3bbf9490e0b080bb75b 5b0fa3c40000001cdf003c55 02422d207f0b 8 0 0
1527751644 [[36.11,19.31,0],[33.32,26.47,12],[23.15,15.27,24]]
1527751620 1527751644


Now my query is how do I flatten the Coordinates values.
I tried below query to get the coordinates but its not giving blank values :
SELECT `t`.`results`.`_id` as `_id`,`t`.`results`.`Session` as
`Session`,`t`.`results`.`Gateway` as `Gateway`,`t`.`results`.`Device` as
`Device`,`t`.`results`.`Client` as `Client`,`t`.`results`.`Category` as
`Category`,
`t`.`results`.`LastUpdate` as
`LastUpdate`,`t`.`results`.`Coordinates[0][1]` as
`Coordinates_x`,`t`.`results`.`Start` as `Start`,`t`.`results`.`End` as
`End` FROM (SELECT FLATTEN(results) as `results` FROM
`tmp`.`default`.`./path/to/file.json` ) `t`

For ease of understanding I removed some of the columns while reading the
data .


Appreciate the help !

Thanks,
Divya
