Here i have this database

I use this as a query to get the object i want
var query = {
"products": {
"$elemMatch": {
"category": '0',
"id": '0'
}
}
};
var secondaryQuery = {
'products.$': 1
};
collection.find(query, secondaryQuery)
The database returns null array [].
Does someone have idea why and how to get the object I want from it?

I start a new video with JSON-RPC call:
{"jsonrpc": "2.0",
"method": "Player.Open",
"params":
{"item":
{"file": "c:\\MyCodes\\samples\\sample-6s.mp4" }},
"id": 1
}
Video started and I want to get the video details and use the following Player.GetItem method:
{
"jsonrpc": "2.0",
"method": "Player.GetItem",
"params": {
"properties": [
"title",
"album",
"artist",
"season",
"episode",
"duration",
"showtitle",
"tvshowid",
"thumbnail",
"file",
"fanart",
"streamdetails"
],
"playerid": 1
},
"id": "VideoGetItem"
}
The problem I got back this:
{
"id": "VideoGetItem",
"jsonrpc": "2.0",
"result": {
"item": {
"album": "",
"artist": [],
"episode": -1,
"fanart": "",
"file": "c:\\MyCodes\\samples\\sample-6s.mp4",
"label": "sample-6s.mp4",
"season": -1,
"showtitle": "",
"streamdetails": {
"audio": [],
"subtitle": [],
"video": []
},
"thumbnail": "",
"title": "",
"tvshowid": -1,
"type": "unknown"
}
}
}
but if I start the same video from KODI GUI I got back this:
{
"id": "VideoGetItem",
"jsonrpc": "2.0",
"result": {
"item": {
"album": "",
"artist": [],
"episode": -1,
"fanart": "",
"file": "C:\\MyCodes\\samples\\sample-6s.mp4",
"label": "sample-6s.mp4",
"season": -1,
"showtitle": "",
"streamdetails": {
"audio": [
{
"channels": 2,
"codec": "mp3",
"language": ""
}
],
"subtitle": [],
"video": [
{
"aspect": 1.3333330154418946,
"codec": "mpeg4",
"duration": 2701,
"hdrtype": "",
"height": 384,
"language": "",
"stereomode": "",
"width": 512
}
]
},
"thumbnail": "image://video#C%3a%5cMyCodes%5csamples%5csample-6s.mp4/",
"title": "",
"tvshowid": -1,
"type": "unknown"
}
}
}
Any idea, or experience? Maybe I should use a different method to get the currently running video details?
I am trying filter the response city wise. I am not able to understand how to query filter parameters.
I have tried different ways but with no success. This is the response without applying filter. But I want filter it for a particular city.

This is only documentation on how to do filtering.
properties: OrderedMap { "id": OrderedMap { "type": "integer" }, "date": OrderedMap { "type": "integer" } }
How to form request url for filtering the response?
yes the documentation is very poor, but still out of many trials I got it work like
this
https://api.data.gov.in/resource/3b01bcb8-0b14-4abf-b6f2-c1bfd384ba69?api-key=<your key>&format=json&offset=0&limit=10
&filters[pollutant_id]=NO2
So I am trying to pivot some large Json arrays into a row by row format (postgres db). So imagine
{“searchResults”:[{“id”:“89705”,“score”:42,“title”:“Foo.”,“properties”:{…
Currently the most results we have in an array is about 300~ id's and explicitly saying;
Data::Json->'searchResults'->0->'tags'->0->>'label' as "Tag - Result 1",
...
Data::Json->'searchResults'->300->'tags'->0->>'label' as "Tag - Result
1",
Ideal Output
Array, ID , Score, Title
----
1 89705, 42, foo
1 89706, 34, bar
2 90003, 54, thing
2 98594, 53, that
(so 1,2 represent different rows in the initial table that both contain ??? amounts of objects the JSON data array)

Any advise on what my options are here ?
Thanks #a_horse_with_no_name this worked perfectly.
it's unclear to me how the JSON continues in the array, but it seems you are looking for something like this:
with testdata(props) as (
values (
'{"searchResults":
[
{"id":"89705","score":42,"title":"Foo"},
{"id":"89706","score":34, "title":"bar"}
]}'::jsonb
)
)
select x.idx,
x.val ->> 'id' as id,
x.val ->> 'score' as score,
x.val ->> 'title' as title
from testdata, jsonb_array_elements(props -> 'searchResults') with ordinality as x (val, idx);
returns
idx | id | score | title
----+-------+-------+------
1 | 89705 | 42 | Foo
2 | 89706 | 34 | bar
Is there any way to find records that collection is empty?
For example please find below array. I want only that records with index "companydata" is empty. and also how can i get data that does not have empty "companydata" data.
Thanks in advance.
