> 1. Get rid of outer flatten : select s1.type type from (select d.type type,
> d.uid uid, flatten(d.map.rm) rms from `data.json` d order by d.uid) s1 order
> by s1.rms.mapid;
> 2. Get rid of the outer order by : select s1.type type, flatten(s1.rms.rptd)
> rptds from (select d.type type, d.uid uid, flatten(d.map.rm) rms from
> `data.json` d order by d.uid) s1;
> 3. Get rid of the inner order by : select s1.type type, flatten(s1.rms.rptd)
> rptds from (select d.type type, d.uid uid, flatten(d.map.rm) rms from
> `data.json` d) s1 order by s1.rms.mapid;
> {code}
> I attached the log file and data file. Let me know if you have any questions
