Traversing JSON objects with tSQL - OPENJSON - sql

Question

I have the following JSON code. I pull the values into a SQL database using OPENJSON, but I am having trouble with the path for the Refund object.
I am trying to pull the "amount" value in the "transactions" object (so the expected value should be 298.47).
SQL code (currently returns only null values)
OPEN(json)
WITH(
OtherJSONstuff varchar '$otherjsonstuff'
Refund int '$.refund[0].transactions.amount' <what should this be
JSON Code
"otherjsonstuff": othervalues
"otherjsonstuff": othervalues
"object": [
{
"id": 212,
"items": [
{
"id": 151,
"quantity": 3,
"item_id": 926,
"subtotal": 30.0,
"tax": 0.0,
"item": {
"id": 926,
"quantity": 3,
"price": "10.00",
"product_id": 934,
"properties": [],
"discount": "0.00",
"tax": []
}
}
],
"action": [
{
"id": 537,
"amount": "298.47", --this is the line I need
"kind": "refund",
"created": "2016-12-13",
"location_id": null,
"parent_id": 537,
}
],
}
],

Answer 1

Having reformatted the JSON code,
it should be $.refund[0].transactions[0].amount
Depend on the array object you want to access, just increment and decrements the values. The root cause is understanding the JSON hierarchy and JNevil has provided you some good resources
