Querying complex nested object in cosmosdb using sql Api - linq

Question

How query only those users whose Itemcount > 10 from the complex nested object(with dynamic key) from comosdb using sql api? UDF not preferred.
Something like,
Select c.username from c where c.Data[*].Order.ItemCount > 10;
{
{
"Username": "User1",
"Data": {
"RandomGUID123": {
"Order": {
"Item": "ItemName123",
"ItemCount" : "40"
},
"ShipmentNumber": "7657575"
},
"RandomGUID976": {
"Order": {
"Item": "ItemName7686"
"ItemCount" : "7"
},
"ShipmentNumber": "876876"
}
}
},
{
"Username": "User2",
"Data": {
"RandomGUID654": {
"Order": {
"Item": "ItemName654",
"ItemCount" : "9"
},
"ShipmentNumber": "7612575"
},
"RandomGUID908": {
"Order": {
"Item": "ItemName545"
"ItemCount" : "6"
},
"ShipmentNumber": "6454"
}
}
}
}

Answer 1

I'm not sure about how to handle unknown keys, but if you're willing to model the key as a value instead (simpler and cleaner I'd argue), you could have:
{
"Username": "User1",
"Data": [
{
"Id": "RandomGUID123",
"Order": {
"Item": "ItemName123",
"ItemCount": 40
},
"ShipmentNumber": "7657575"
},
{
"Id": "RandomGUID976",
"Order": {
"Item": "ItemName7686",
"ItemCount": 7
},
"ShipmentNumber": "876876"
}
]
}
With a query like:
SELECT DISTINCT VALUE(c.Username)
FROM c
JOIN (SELECT VALUE d from d IN c.Data where d["Order"].ItemCount > 10)
Result:
[
"User1"
]
"Order" is a reserved keyword and requires the bracket syntax to reference.

As Noah answers,model the key as a value is a way to achieve.
Additionally,there is another way to achieve without changing your schema of your document .Create UDF like this:
function getResult(data){
for(var key in data){
const itemCount = data[key].Order.ItemCount;
if (parseFloat(itemCount).toString() != "NaN" && parseFloat(itemCount) > 10 ) {
　　　　return true;
　　}
}
return false;
}
Then run this sql:
SELECT c.Username FROM c where udf.getResult(c.Data)
Result:
[
{
"Username": "User1"
}
]
