Get nested data c.<type>.<type> in SQL Query? - sql

Question

I've been searching everywhere for this seemingly simple action: I'd like to select only a certain few data type from a nested source.
The closest that I can get to the solution is this:
SELECT c.receipt_number, c.millitime, c.email, c.phone, c.shipping, c.shipping_note, c.amount_paid, i.description, i.quantity
FROM c
JOIN i IN c.line_items
WHERE c.millitime > 1627813253000
But this will create lots of duplicated data, like the receipt_number, email, etc in the example:
[
{
"receipt_number": null,
"millitime": 1627813377000,
"email": "test#gmail.com",
"phone": "000000000",
"shipping": {
"address": {
"city": "Sydney",
"country": "AU",
"line1": "Test Street",
"line2": null,
"postal_code": "3000",
"state": "VIC"
},
"name": "New Cust"
},
"shipping_note": "Please knock on door.",
"amount_paid": 104,
"description": "Curry Chicken",
"quantity": 1
},
{
"receipt_number": null,
"millitime": 1627813377000,
"email": "test#gmail.com",
"phone": "000000000",
"shipping": {
"address": {
"city": "Sydney",
"country": "AU",
"line1": "Test Street",
"line2": null,
"postal_code": "3000",
"state": "VIC"
},
"name": "New Cust"
},
"shipping_note": "Please knock on door.",
"amount_paid": 104,
"description": "Chicken Noodle",
"quantity": 8
}
]
Is there a way to create a nested result of c.line_items with just the desired data description and quantity? The final result should be similar to:
[
{
"receipt_number": null,
"millitime": 1627813377000,
"email": "test#gmail.com",
"phone": "000000000",
"shipping": {
"address": {
"city": "Sydney",
"country": "AU",
"line1": "Test Street",
"line2": null,
"postal_code": "3000",
"state": "VIC"
},
"name": "New Cust"
},
"shipping_note": "Please knock on door.",
"amount_paid": 104,
"line_items": [
{
"description": "Chicken Noodle",
"quantity": 8
},
{
"description": "Curry Chicken",
"quantity": 1
}
]
}
]

You can use distinct keyword to remove duplicates from the results.
Add c.line_items to your select list and change i.description, i.quantity to c.description, c.quantity to add view under line_items.
Query:
SELECT distinct c.receipt_number, c.millitime, c.email, c.phone, c.shipping, c.shipping_note, c.amount_paid, c.line_items
FROM c
JOIN i IN c.line_items
WHERE c.millitime > 1627813253000
Result:
