I want to extract values from an JSON document with using the path operators.
For example I get all the product IDs included in the file via $..product_id.
But for getting the "id" when I use $..id I get an output for each id element, no matter on which level of the JSON the variable is.
For example in my output I get an row for the id "12345678" as well as for "11223344" which should not be because it is a subset of the first ID.
{
"next_offset": 20,
"records": [
{
"id": "12345678",
"date": "2020-02-14",
"product_id": "asdf1234",
"product_name": "Product_test^_1",
"template_link": {
"name": "aassddff",
"id": "11223344",
"_acl": {
"fields": [],
"_hash": "345thvz356b56v456b"
}
},
....
}
]
}
How can I set the path operator to only access the "id" fields of one specific level?
For the JSON shown in your question, use $.records.*.id.

I have a nested JSON in a field that contains multiple important keys that I would like to retrieve as an array:
{
"tasks": [
{
"id": "task_1",
"name": "task_1_name",
"assignees": [
{
"id": "assignee_1",
"name": "assignee_1_name"
}
]
},
{
"id": "task_2",
"name": "task_2_name",
"assignees": [
{
"id": "assignee_2",
"name": "assignee_2_name"
},
{
"id": "assignee_3",
"name": "assignee_3_name"
}
]}]}
All the queries that I've tried so far fx ( $.tasks.*.assignees..id) and many others have returned
[
"assignee_1",
"assignee_2",
"assignee_3"
]
But what I need is:
[
["assignee_1"],
["assignee_2", "assignee_3"]
]
Is it possible to do with JSONPath or any script inside of it, without involving 3rd party tools?
The problem you're facing is that tasks and assignees are arrays. You need to use [*] instead of .* to get the items in the array. So your path should look like
$.tasks[*].assignees[*].id
You can try it at https://json-everything.net/json-path.
NOTE The output from my site will give you both the value and its location within the original document.
Edit
(I didn't read the whole thing :) )
You're not going to be able to get
[
["assignee_1"],
["assignee_2", "assignee_3"]
]
because, as #Tomalak mentioned, JSON Path is a query language. It's going to remove all structure and return only values.
I am new to JSON Path and I am trying to get 'id' corresponding to name='Candy' using JsonPath in below JSON payload.
{
"responsePayload": [
{
"content": {
"id": "101",
"name": "Candy"
},
"links": [
{
"rel": "self",
"link": "api/v1/sweets/101",
"id": "101"
}
]
},
{
"content": {
"id": "102",
"name": "Chocolate"
},
"links": [
{
"rel": "self",
"link": "api/v1/sweets/102",
"id": "102"
}
]
}
]
}
For this I tried Jsonpath $.responsePayload[0].content[?(#.name=='Candy')].id but that is not working. I am using https://jsonpath.com/ for testing this JsonPath. Please guide me how I can achieve required result.
You're really close. You need more of the path inside the expression.
$.responsePayload[?(#.content.name=='Candy')].content.id
The [0] you have in your response isolates the first element only, but it sounds like you want to iterate over the whole array in responsePayload. To do that, the filter expression selector [?(...)] must act on that array.
Next, the # represents the current item, and you can build a full path off of it. You can see how that works above.
Finally, the filter expression selector returns the full item when the expression returns true. So you then need to navigate into .content.id again to get the value you're after.
In my DB I have a column storing JSON. The JSON looks like this:
{
"views": [
{
"id": "1",
"sections": [
{
"id": "1",
"isToggleActive": false,
"components": [
{
"id": "1",
"values": [
"02/24/2021"
]
},
{
"id": "2",
"values": []
},
{
"id": "3",
"values": [
"5393",
"02/26/2021 - Weekly"
]
},
{
"id": "5",
"values": [
""
]
}
]
}
]
}
]
}
I want to create a migration script that will extract a value from this JSON and store them in its own column.
In the JSON above, in that components array, I want to extract the second value from the component with an ID of "3" (among other things, but this is a good example). So, I want to extract the value "02/26/2021 - Weekly" to store in its own column.
I was looking at the JSON_VALUE docs, but I only see examples for specifing indexes for the json properties. I can't figure out what kind of json path I'd need. Is this even possible to do with JSON_VALUE?
EDIT: To clarify, the views and sections components can have static array indexes, so I can use views[0].sections[0] for them. Currently, this is all I have with my SQL query:
SELECT
*
FROM OPENJSON(#jsonInfo, '$.views[0].sections[0]')
You need to use OPENJSON to break out the inner array, then filter it with a WHERE and finally select the correct value with JSON_VALUE
SELECT
JSON_VALUE(components.value, '$.values[1]')
FROM OPENJSON (#jsonInfo, '$.views[0].sections[0].components') components
WHERE JSON_VALUE(components.value, '$.id') = '3'
{
"metadata": {
"id": "2",
"uri": "3",
"type": "2"
},
"Number": "2323600002913",
"Date": "04/21/2009",
"postingDate": "00/00/0000",
"ata": {
"results": [
{
"metadata": {
"id": "r",
"uri": "e2",
"type": "s2"
},
"item": "000010",
"data":"ad"
}
]
}
}
want to remove metadata property from above json message and output should be like below
{
"Number": "2323600002913",
"Date": "04/21/2009",
"postingDate": "00/00/0000",
"ata": {
"results": [
{
"item": "000010",
"data":"ad"
}
]
}
}
I tried with removeProperty() which is working for root level metadata but inside metadata not removed.
how to use replace() in this case or anything else to only remove metadata.
The simplest way is use inline code, cause even with removeProperty() expression to remove the metadata under results, it will return the results array data not the whole json data. Then you will have to combine them, it's not a convenient way.
And with inline code you could refer to my below picture. The variable json is the value from triggerbody, then just delete the node or key and return the json variable. And with this way, even you want to delete many metadata in the array, you could add a for loop to delete it, just think of it as plain js code.
Update:if you want to get value from variable,cause no support expression to get value from variable so use the below expression.
var json =wworkflowContext.actions.Initialize_variable.inputs.variables[0].value;
And about how to loop the array in the json refer to my below pic.
I'm getting following data in response of a request:
{
"items": [
{
"id": 54925,
"currCode": "USD",
"lastUpdated": 1531233169000
},
{
"id": 54926,
"currCode": "USD",
"lastUpdated": 1531233169000
},
{
"id": 54927,
"currCode": "USD",
"lastUpdated": 1531233169000
}
],
"totalCount": 3
}
As we can see there are three different ids in the data(54925,54926,54927)
I want to perform iterate over all these ids and perform some operation( basically I want to use like foreach(String id: ids) { request(id);}
I added a JSON extractor as follows:
As per my research(research link) it's supposed to store all the ids in the id_list
After this added a foreach loop to iterate over these values:
But somehow the it's not going inside this for loop. What I'm doing wrong here?
is there any other way to fetch all these ids and loop through them?
You forgot to mention in JSON Extractor you expect it to return all values by setting Match No. as -1
-1 means extract all results, they will be named as _N
