I have json that looks like:
{
"base": "abc",
"members" : [
{"fn": "maurice", "ln": "hickey"},
{"fn": "john", "ln": "smith"},
{"fn": "robin", "ln": "smith"},
...
],
"date": "2018-08-26"
}
I am trying to write a jq filter to give me the same schema output but with only a subset of the members array e.g. all the "smith"s
{
"base": "abc",
"members" : [
{"fn": "john", "ln": "smith"},
{"fn": "robin", "ln": "smith"}
],
"date": "2018-08-26"
}
Any pointers would be appreciated.
This gets the desired output.
jq '.members |= map(select(.ln == "smith"))'
It updates .members, selecting only objects with .ln == smith

I have the following JSON input:
{
"paging": {
"count": 0,
"total": 0,
"offset": 0,
"max": 0
},
"executions": [
{
"id": 5,
"href": "https://localhost.com.br",
"permalink": "https://localhost.com.br",
"status": "succeeded",
"project": "PROJETO",
"executionType": "scheduled",
"date-started": {
"unixtime": 1660793400012,
"date": "2022-08-18T03:30:00Z"
},
"date-ended": {
"unixtime": 1660793409694,
"date": "2022-08-18T03:30:09Z"
},
"job": {
"id": "cdkwednweoi-8745bjdf-kcjkjr8745",
"averageDuration": 0,
"name": "routine",
"group": "",
"project": "PROJECT",
"description": "",
"href": "https://localhost.com.br",
"permalink": "https://localhost.com.br"
},
"description": "runner",
"argstring": null,
"serverUUID": "jdnsdnasldnaje382nf5ubv",
"successfulNodes": [
"84jsk937nf"
]
}
]
}
First I want to select an array by a property name. And then I want to select an object of the array by the value of the propertyes.
Example of the desired informations on output:
"href"
"status"
"project"
"date-started":
"unixtime": 48298437239847,
"date": "2022-07-17"
"date-ended":
"unixtime": 48298437239847,
"date": "2022-07-17"
"job":
"name": "cleaner"
I knew how to get the firts values:
jq -r '.executions[] | [.href, .status, .project']
But the other ones I don't know how to do, I've tried with:
jq '.executions[] | with_entries( select(.value | has("date-started") ) )'
But it doesn't works.
Your first query produces a JSON array, so in this response, I'll assume it will suffice to produce an array of the eight values of interest in the order you've specified.
With your input, the following invocation produces the eight values as shown below:
jq '.executions[]
| [.href, .status, .project,
(."date-started" | (.unixtime, .date)),
(."date-ended" | (.unixtime, .date)),
.job.name]'
Output:
[
"https://localhost.com.br/rundeck/api/40/execution/2340",
"succeeded",
"PROJETO",
1660793400012,
"2022-08-18T03:30:00Z",
1660793409694,
"2022-08-18T03:30:09Z",

I have MarkLogic 9 on my database.
I have created the following documents in my database:
test1.json
{
"users": [
{
"userId": "A",
"value": 0
}
]
}
test2.json
{
"users": [
{
"userId": "A",
"value": "0"
}
]
}
test3.json
{
"users": [
{
"value": 0,
"userId": "A"
}
]
}
test4.json
{
"users": [
{
"value": "0",
"userId": "A"
}
]
}
I have run the following codes and have recorded the results:
cts.uris(“”, null, cts.jsonPropertyScopeQuery(
"users",
cts.andQuery(
[
cts.jsonPropertyValueQuery('userId', "A"),
cts.jsonPropertyValueQuery('value', "0"),
]
)
))
Result: test2.json, test4.json
cts.uris(“”, null, cts.jsonPropertyScopeQuery(
"users",
cts.andQuery(
[
cts.jsonPropertyValueQuery('userId', "A"),
cts.jsonPropertyValueQuery('value', 0),
]
)
))
Result: test3.json
I was wondering why test1.json did not return in the 2nd query while test3.json did. They both had the same values for fields but in different order. The order of the fields are different in test2.json and test4.json, however, the query returned both documents. The only difference between the 2 pairs that I can think of is that there are 2 data types for the field “value”, integer and string.
How would I go about resolving this issue?
https://docs.marklogic.com/cts.jsonPropertyValueQuery shows the value to match as an array.
If you want to keep the variants in data, maybe you can try something on the query side like cts.jsonPropertyValueQuery('value', ["0", 0])
I have a structure that looks like so
[
[
{
"ID": "grp1-001",
},
{
"ID": "grp1-002",
},
{
"ID": "grp1-003",
},
{
"ID": "grp1-004",
},
{
"ID": "grp1-005",
},
{
"ID": "grp1-006",
}
],
[
{
"ID": "grp2-001",
},
{
"ID": "grp2-002",
},
{
"ID": "grp2-003",
},
{
"ID": "grp2-004",
},
{
"ID": "grp2-005",
},
{
"ID": "grp2-006",
}
.......
what I need to get as a result of the modification is this
[
[
["1", "grp1-001"],
["2", "grp1-002"],
["3", "grp1-003"],
["4", "grp1-004"],
["5", "grp1-005"],
["6", "grp1-006"],
],
[
["1", "grp2-001"],
["2", "grp2-002"],
["3", "grp2-003"],
["4", "grp2-004"],
["5", "grp2-005"],
["6", "grp2-006"],
],
Which means I need to keep the external structure (outside array and an internal grouping) but convert the inner dict to an array and replace the "ID" key with a value (that will come from external source like --argjson). I am not even sure how to start - any ideas/resources are highly appreciated.
Assuming you're just taking the objects and transforming them to pairs of the index in the array and the ID value, you could do this:
map([to_entries[] | [.key + 1, .value.ID | tostring]])
https://jqplay.org/s/RBac7SPfdG
Using to_entries/0 on an array gives you an array of key/value (index/value) pairs. You could then shift the indices by 1 and convert to strings.
Here's my input json:
{
"channels": [
{ "id": 1, "name": "Pop"},
{ "id": 2, "name": "Rock"}
],
"links": [
{ "id": 2, "streams": [ {"url": "http://example.com/rock"} ] },
{ "id": 1, "streams": [ {"url": "http://example.com/pop"} ] }
]
}
This is what I want as an output:
"http://example.com/pop"
"Pop"
"http://example.com/rock"
"Rock"
So I need jq to replace .channels[].id with .links[].streams[0].url based on .links[].id
I don't know if it's right, but this is how I managed to output the urls:
(.channels[].id | tostring) as $ids | [.links[]] | map({(.id | tostring): .streams[0].url}) | add as $urls | $urls[$ids]
"http://example.com/pop"
"http://example.com/rock"
The question is, how do I add .channels[].name to it?
You sometimes have to be careful what you ask for, but this will produce the result you said you want:
.channels[] as $channel
| $channel.name,
(.links[] | select(.id == $channel.id) | .streams[0].url)
Output for the given input:
"Pop"
"http://example.com/pop"
"Rock"
"http://example.com/rock"
Here is a solution which uses reduce and setpath to make a $urls lookup table from .links and then scans .channels generating corresponding urls and names.
(
reduce .links[] as $l (
{};
setpath([ $l.id|tostring ]; [$l.streams[].url])
)
) as $urls
| .channels[]
| $urls[ .id|tostring ][], .name
If multiple urls are present in the "streams" attribute this will
print them all before printing the name. e.g. if the input is
{
"channels": [
{ "id": 1, "name": "Pop"},
{ "id": 2, "name": "Rock"}
],
"links": [
{ "id": 2, "streams": [ {"url": "http://example.com/rock"},
{"url": "http://example.com/hardrock"} ] },
{ "id": 1, "streams": [ {"url": "http://example.com/pop"} ] }
]
}
the output will be
"http://example.com/pop"
"Pop"
"http://example.com/rock"
"http://example.com/hardrock"
"Rock"
I am trying to get a value from the Json using JQ.
I have to get a ID from the inputJson , (activeItem) and use that ID to get the name of the element from list of items below.
Can this be done in single query ?
{
"amazon": {
"activeitem" : 2,
"items": [
{
"id" : 1,
"name": "harry potter",
"state": "sold"
},
{
"id" : 2,
"name": "adidas shoes",
"state": "in inventory"
},
{
"id" : 3,
"name": "watch",
"state": "returned"
}
]
}
}
Now i am getting the value first and the filtering, instead i want to do in single query.
With your data, the filter:
.amazon
| .activeitem as $id
| .items[]
| select(.id == $id)
| .name
produces:
"adidas shoes"
(Use the -r command-line option if you want the raw string.)
