I have a table called "json" in my database, with 2 columns: "id" and "data"
Only one row is stored inside it at the moment, having 1 as id and a JSON structure as data:
{
"elements": {
"nodes": [
{
"data": {
"id": "n0",
"name": "Name here",
"color": "#FFFFFF"
}
},
{
"bob": "hello"
}
]
}
}
I need to update a key of the json: "Name here" has to become "updated"
This is what I tried:
db.query("UPDATE json SET $1 WHERE data->'elements'->'nodes'->0->'data'->'name'=$2", ['updated', 'Name here'])
but I get an error:
syntax error at or near "'updated'"
When using the Postgres JSON navigators it's important to terminate your chain with the text retrieval navigator ->> if you want to do comparisons like that:
UPDATE json SET $1 WHERE data->'elements'->'nodes'->0->'data'->>'name'=$2
That should permit comparing text to text instead of json.
I think you might also be able to use #>> to dig the whole way down in one shot:
UPDATE json SET $1 WHERE data#>>'{elements,nodes,0,data,name}'=$2

I have a Cosmos DB with documents that look like the following:
{
"name": {
"productName": "someProductName"
},
"identifiers": [
{
"identifierCode": "1234",
"identifierLabel": "someLabel1"
},
{
"identifierCode": "432",
"identifierLabel": "someLabel2"
}
]
}
I would like to write a sql query to obtain an entire document using "identifierLabel" as a filter when searching for the document.
I attempted to write a query based on an example I found from the following blog:
SELECT c,t AS identifiers
FROM c
JOIN t in c.identifiers
WHERE t.identifierLabel = "someLabel2"
However, when the result is returned, it appends the following to the end of the document:
{
"name": {
"productName": "someProductName"
},
"identifiers": [
{
"identifierCode": "1234",
"identifierLabel": "someLabel1"
},
{
"identifierCode": "432",
"identifierLabel": "someLabel2"
}
]
},
{
"identifierCode": "432",
"identifierLabel": "someLabel2"
}
How can I avoid this and get the result that I desire, i.e. the entire document with nothing appended to it?
Thanks in advance.
Using ARRAY_CONTAINS(), you should be able to do something like this to retrieve the entire document, without any need for a self-join:
SELECT *
FROM c
where ARRAY_CONTAINS(c.identifiers, {"identifierLabel":"someLabel2"}, true)
Note that ARRAY_CONTAINS() can search for either scalar values or objects. By specifying true as the third parameter, it signifies searching through objects. So, in the above query, it's searching all objects in the array where identifierLabel is set to "someLabel2" (and then it should be returning the original document, unchanged, avoiding the issue you ran into with the self-join).
I am new to elasticsearch i want to index a JSON file and perform search queries from elasticsearch
How can I index this json and perform queries to get value if i pass parameter as "field3.innerfield" : "someval"
I have tried indexing this file with helpers.bulk and search but it returns all the fields instead of a selected field.
Below is the JSON sample
[
{
"id": "someid",
"metadata": {
"docType": "value",
"otherfield": " ",
morefields
.
.
},
"field1":"value1",
"field2":"value2,
"field3": [
{
"innerfield": "someval",
"innerfield1":[
"kind of a paragraph"
]
}
],
"field4": [
{
"innerfield": "someval",
"innerfield1": "kind of a paragraph"
}
],
},
{ again the format repeats with different id but same fields
},
{
}
]
Your question lacks clarity however what I understood is that you want to fetch values from its key for a nested json. You can do that in the following way as shown below.
Parse it multiple times and make the required changes as per your need.
import json
data = data.apply(lambda x: json.loads(json.loads(x).get("metadata","{}")).get("doctype") if x else None)
I am building a Azure Logic App which recieves a webhook. I need to parse the body and validate if a array contains any object with a property that matches either of two values, but have no idea how to do it.
Any ideas?
The JSON i am recieving in the webhook is like below, shortened for brevity. I am looking at the components-array:
{
"id": "12601",
"components": [
{
"id": "10021",
"name": "Value1"
},
{
"id": "10022",
"name": "Value2"
},
{
"id": "10023",
"name": "Value3"
}
]
}
From this array I need to output a parameter true/false if any properties with name == "Value1" or "Value" appears.
Is there any syntax similar to LINQ in C#, or do you use a foreach? I have not been able to find any simple way like:
If(Arr.Any(x => x.name == "Value1"))
Perhaps you can use Parse Json to parse the Json string you received, and then use condition to determine whether the name contains value1.
Please refer to my logic app:
I have an Excel sheet with a column containing IDs of items I want to retrieve
||ID||
|123|
|124|
|125|
The API I am calling can take an array of IDs as input (e.g. https://API.com/rest/items?ID=123&ID=124&ID=125....(up to 50))
and returns one JSON.
"data": [
{
"id": 123,
"fields": {
"name": "blah blah",
"description": "some description",
}
},
{
"id": 124,
"fields": {
"name": "blah bli",
"description": "some description",
}
},
{
"id": 125,
"fields": {
"name": "blah blo",
"description": "some description",
}
},...
]
}
I would like to load data from this JSON in another table or sheet.
||ID||Name||
|123|blah blah|
|124|blahblo|
|125|blahbli|
I would know how to parameterise the query by referencing single cells, but if I am retrieving 100+ items, that's a lot of work.
Can't I somehow build a query that gets each value (ID) from the table or range in one simple move?
--edit1--
Found another API endpoint where I can provide an array of IDs. (before I thought it was only possible to send one ID per request to retrieve one JSON at a time)
--edit2--
Maybe I can concatenate all IDs into the request URL already in an Excel cell and parameterise just based on that one cell. (still experimenting)
If you've got the JSON for each ID, then you just need to pull out the name part.
For example, if you have a column [JSON] with the JSON for each ID, then you can create a custom column using Json.Document([JSON])[data][name] as the formula.
You can likely combine pulling the JSON and parsing it into a single step if you'd like.
I have following problem
I have a field mapping update to an index .Payload is complex where
I have:
{
"type": "abc",
"Party": [{
"Type": "abc",
"Id": "123",
"Name": "manasa",
"Phone": [{
"Type": "Office",
"Number": "12345"
}]
}]
}
And now I want to create a field for an index. The field name is phonenumber of type Collection(Edm.String)
where mapping is
{
"sourceFieldName" : "/Party/Phone/Number",
"targetFieldName" : "phonenumber",
"mappingFunction" : { "name" : "jsonArrayToStringCollection" }
}
In http post body
But still after indexing i get phone number result as null.That means the mapping went wrong.If you see the phone number in source json, it is inside a json array and it itself is an array and result needs to get stored inside a collection of a string.Is it possible how can I achieve this?
If this is not possible I atleast want field mapping till phone array ie., /Party/Phone/
If i index complete party array as a text, I get an error while running the index saying:
"Field 'partydetails' contains a term that is too large to process. The max length for UTF-8 encoded terms is 32766 bytes. The most likely cause of this error is that filtering, sorting, and/or faceting are enabled on this field, which causes the entire field value to be indexed as a single term. Please avoid the use of these options for large fields."
Can someone please help!
If party would have been a Json object than an array and phone would have been only a string array for example
{
"type": "abc",
"Party": {
"Type": "abc",
"Id": "123",
"Name": "manasa",
"Phone": [{
"12345",
"23463"
}]
}
}
Then I could have mapped
{
"sourceFieldName" : "Party/Phonenumber",
"targetFieldName" : "phonenumbers",
"mappingFunction" : { "name" : "jsonArrayToStringCollection" }
}
It map as collection of type odata EDM.string.
So to put this in better and straight forward way,
Either transform your json to something flatter (the example that I
gave above) or
Use the proper index incase if you know before inhand as
#Luis Cabrera said,
“sourceFieldName”: “/Party/0/Phone/0/Type
It is a limitation from azure search side.
Note that Party and Phone are arrays, so the field mapping you mention won't work.
You will need to index into the specific element. For example:
{
"sourceFieldName": "/Party/0/Phone/0/Type",
"targetFieldName": "firstPhoneNumberTypeOfFirstParty"
}
You may want to give that a shot.
Thanks!
