like this -> total_amountA : 20, total_amountB : 10
how can i get the sum of all value..? plese help me
The Stats Component gives you a set of statistics for a given field for a given query.
http://localhost:8983/solr/corename/select?q=your:query&stats=true&stats.field=total_amount
Should give you an additional stats key in the response with sum among the values calculated.

I have the fallowing JSON object and I want to take the value of Microsoft.VSTS.Scheduling.RemainingWork
[
{
"id": 13,
"rev": 12,
"fields": {
"System.Id": 13,
"Microsoft.VSTS.Scheduling.RemainingWork": 32,
"Microsoft.VSTS.Scheduling.CompletedWork": 20
},
"url": "https://dev.azure.com/.../_apis/wit/workItems/13"
}
]
I am able retrieve data until some point:
console.log("object of json : ",result);
console.log("result[0] : ", result[0])
console.log("result[0].fields : ", result[0].fields)
The console output is,
But I this is not working result[0].fields.Microsoft.VSTS.Scheduling.RemainingWork
You can access data like an associative array :
result[0].fields['Microsoft.VSTS.Scheduling.RemainingWork']
You need to use
result[0].fields["Microsoft.VSTS.Scheduling.RemainingWork"]
Basically when you use
result[0].fields.Microsoft.VSTS.Scheduling.RemainingWork
each time you use a ".", you are trying to get the value from a nested object, like this -
[
{
"id": 13,
"rev": 12,
"fields": {
"System.Id": 13,
"Microsoft": {
"VSTS": {
"Scheduling": {
"RemainingWork": 32
}
}
},
"Microsoft.VSTS.Scheduling.CompletedWork": 20
},
"url": "https://dev.azure.com/.../_apis/wit/workItems/13"
}
]
which is not correct since that is not the way your data is structured.
Hi I am trying to select Status from Json Array in azure data factory

I have tried selecting #activity('Copy data From CCP TO Blob').output.executionDetails.status.It throws an error:
'Array elements can only be selected using an integer index'.
Any way to resolve it?
executionDetails is an array, you have to set index to refer elements in it.
Please try:
#activity('Copy data From CCP TO Blob').output.executionDetails[0].status
Thank you for the reply
Yes, we have to use slicing and indexing the lists and Dictionaries
I have tried Dispensing_Unit_Master_Dim
#activity('Copy data From CCP TO Blob').output.executionDetails[0]['status'] and it works
0 and status there is no Dot
I am using AWS Step Functions which utilizes JSONPath for providing JSON paths. I have the following input :
{
"response": {
"isSuccess": true,
"error": "",
"body": {
"count": 2,
"fields": [
{
"fieldId": 1,
"tabId": 100,
"title": "First Name"
},
{
"fieldId": 2,
"tabId": 100,
"title": "Last Name"
}
]
}
},
"iteration": {
"totalCount": 2,
"currentCount": 0,
"step": 1
}
}
I want to query the fields array as:
$.response.body.fields[$.iteration.currentCount]
The value of currentCount is incremented by 1 as part of an iteration.
I am getting an invalid XPath exception when trying to use the above.
Can someone please advice on how to provide a dynamic property value to read array values?
As described on https://github.com/json-path/JsonPath#operators you can index an array with a number only. However, you can use a filter expression to select a specific item from the array as follows.
Assuming you have another field that denotes the index such as:
{
"index": 0,
"fieldId": 2,
"tabId": 100,
"title": "Last Name"
}
You can then do
$.response.body.fields[?(#.index==$.iteration.currentCount)]
I am using MySQL 5.7+ with the native JSON data type. Sample data:
[
{
"code": 2,
"stores": [
{
"code": 100,
"quantity": 2
},
{
"code": 200,
"quantity": 3
}
]
},
{
"code": 4,
"stores": [
{
"code": 300,
"quantity": 4
},
{
"code": 400,
"quantity": 5
}
]
}
]
Question: how do I extract an array where code = 4?
The following (working) query has the position of the data I want to extract and the search criterion hardcoded:
SELECT JSON_EXTRACT(data_column, '$[0]')
FROM json_data_table
WHERE data_column->'$[1].code' = 4
I tried using a wildcard (data_column->'$[*].code' = 4) but I get no results in return.
SELECT row FROM
(
SELECT data_column->"[*]" as row
FROM json_data_table
WHERE 4 IN JSON_EXTRACT(data_column, '$[*].code')
)
WHERE row->".code" = 4
... though this would be much easier to work with if this wasn't an unindexed array of objects at the top level. You may want to consider some adjustments to the schema.
Note:
If you have multiple rows in your data, specifying "$[i]" will pick that row, not the aggregate of it. With your dataset, "$[1].code" will always evaluate to the value of code in that single row.
Essentially, you were saying:
$ json collection
[1] second object in the collection.
.code attribute labeled "code".
... since there will only ever be one match for that query, it will always eval to 4...
WHERE 4 = 4
Alternate data structure if possible
Since the entire purpose of "code" is as a key, make it the key.
[
"code2":{
"stores": [
{
"code": 100,
"quantity": 2
},
{
"code": 200,
"quantity": 3
}
]
},
"code4": {
"stores": [
{
"code": 300,
"quantity": 4
},
{
"code": 400,
"quantity": 5
}
]
}
]
Then, all it would require would be:
SELECT datacolumn->"[code4]" as code4
FROM json_data_table
This is what you are looking for.
SELECT data_column->'$[*]' FROM json_data_table where data_column->'$[*].code' like '%4%'.
The selected data will have [] around it when selecting from an array thus data_column->'$[*].code' = 4 is not possible.
I deleted an item you do not need to solr, but I solr response still appears.
The json:
{
"responseHeader": {
"status": 0,
"QTime": 1,
"params": {
"facet": "true",
"q": "*:*",
"facet.limit": "-1",
"facet.field": "manufacturer",
"wt": "json",
"rows": "0"
}
},
"response": {
"numFound": 84,
"start": 0,
"docs": []
},
"facet_counts": {
"facet_queries": {},
"facet_fields": {
"manufacturer": [
"Chevrolet",
0,
"abarth",
1,
"audi",
7,
"austin",
1,
"bmw",
2,
"daewoo",
2,
"ford",
1,
"fso",
1,
"honda",

"hyundai",

"jaguar",

"lexus",

"mazda",

1,
"nissan",
1,
"pontiac",
1,
"seat",
1
]
},
"facet_dates": {},
"facet_ranges": {}
}
}
the deleted item is "chevrolet", now this to '0 'but it still appears.
"manufacturer":["Chevrolet",0,
I wish I could delete the item completely, is that possible.. Thanks.
Here is a two step approach I would follow:
Make sure changes(deletion) is committed. You may issue a commit
If it still shows facets with zero count, you may append &facet.mincount=1 to your query
&facet.mincount=1 will make sure facets with zero count do not show up.
For more details, please refer to: http://wiki.apache.org/solr/SimpleFacetParameters#facet.mincount
In your case probably it is because of uninverted index created by solr.
Pass facet.mincount=1 in your query to get rid of this problem.
