json - array indexing in N1QL -

i ran query: select z data x unnest x.m2 y unnest y.country z; on json document:

{   "data": {     "country": [     { "name": "canada" },     { "name": "greece" }     ]   } }

and got result:

[   {     "z": {       "name": "canada"     }   },   {     "z": {       "name": "greece"    }   } ]

i want select first country name (canada) , tried doing this:

select z[0] data x unnest x.m2 y unnest y.country z;

but return empty results. idea how it?

ignoring m2, do:

select z data x unnest x.data y unnest y.country z limit 1;
