I have the following json Response and I'm trying to parse it, in DB2 v11.
The problem is that I'm not able to so.
The values 3e00a201d9d1b89732bf8c7a00aa7477ac7212354172ad7780e5296803ad6bbb and 4e00a201d9d1b89732bf8c7a00aa7477ac7212354172ad7780e5296803ad62cd
are IDs and can have up to 60 in the response.
For me to do this, I would need like a kind of TAG for those IDs to be able to select them.
Then is there any ways to do this please ? Thank You -

I tries this ...

FROM SYSIBM.SYSDUMMY1
SELECT ID,SYSTOOLS.BSON2JSON(jsonfield) AS JSON_INFO FROM tablejson
SELECT JSON_VAL(jsonfield,'*.signature','s:1000') FROM tablejson
But what yes is working is if I write directly the ID, but this is not helping a lot as the query should be generic.
SELECT JSON_VAL(jsonfield, '4e00a201d9d1b89732bf8c7a00aa7477ac7212354172ad7780e5296803ad62cd.found' ,'s:1000')
FROM tablejson
As the OUTPUT , I would like something like 3 fields
IDs found signature
3e00a201d9d1b89732bf8... true FhNzQ3N2FjNzIxMjM1ND...
4e00a201d9d1b89732bf8... flase FhNzQ3N2FjNzIxMjM1ND...

Good day,
I've found a couple solutions on S.O pertaining to finding rows with its JSON column having a specified value.
The issue I'm currently facing, is that my specific JSON column (session_data) contains a multidimensional array, with one or several values:
{
"lastMessages": [
{
"eventId": "1",
"replyDate": "2022-11-23T05:47:18.577Z",
"replyPreview": "response-text-a"
},
{
"eventId": "2",
"replyDate": "2022-11-23T05:48:14.550Z",
"replyPreview": "response-text-b"
},
{
"eventId": "3",
"replyDate": "2022-11-23T06:23:53.234Z",
"replyPreview": "response-text-c"
},
{
"eventId": "4",
"replyDate": "2022-11-23T06:24:13.555Z",
"replyPreview": "response-text-d"
},
{
"eventId": "5",
"replyDate": "2022-11-23T06:24:30.919Z",
"replyPreview": "response-text-z"
}
],
"workflows": {},
"slots": {}
}
How would I go about retrieving all rows from a table where the JSON column array's replyPreview property contains the value response-text-z?
I've tried the following:
SELECT * FROM dialog_sessions WHERE (session_data->'lastMessages')::jsonb ? 'response-text-z' LIMIT 100
however to no avail.
You can use a JSON path expression:
select *
from dialog_sessions
where session_data #? '$.lastMessages[*].replyReview == "response-text-z"'
If you are on an older Postgres version you can try the #> operator:
select *
from dialog_sessions
where session_data -> 'lastMessages' #> '[{"replyPreview": "response-text-z"}]'
DbFiddle using Postgres 11
I have the following json object stored into a jsonb column
{
"msrp": 6000,
"data": [
{
"supplier": "a",
"price": 5775
},
{
"supplier": "b",
"price": 6129
},
{
"supplier": "c",
"price": 5224
},
{
"supplier": "d",
"price": 5775
}
]
}
There's a few things I'm trying to do but completely stuck on :(
Check if a supplier exists inside this array. So if I'm looking up if "supplier": "e" is in here. Here's what I tried but didn't work. "where data #> '{"supplier": "e"}'"
(optional but really nice to have) Before returning results if I do a select *, inject into each array a "price_diff" so that I can see the difference between msrp and the supplier price as such.
{
"supplier": "d",
"price": 5775,
"price_diff": 225
}
where data #> '{"supplier": "e"}'
Do you have a column named data? You can't just treat a JSONB key name as if it were a column name.
Containment starts from the root.
colname #> '{"data":[{"supplier": "e"}]}'
You can redefine the 'root' dynamically though:
colname->'data' #> '[{"supplier": "e"}]'
Given a jsonb and set of keys how can I get a new jsonb with required keys.
I've tried extracting key-values and assigned to text[] and then using jsonb_object(text[]). It works well, but the problem comes when a key has a array of jsons.
create table my_jsonb_table
(
data_col jsonb
);
insert into my_jsonb_table (data_col) Values ('{
"schemaVersion": "1",
"Id": "20180601550002",
"Domains": [
{
"UID": "29aa2923",
"quantity": 1,
"item": "book",
"DepartmentDomain": {
"type": "paper",
"departId": "10"
},
"PriceDomain": {
"Price": 79.00,
"taxA": 6.500,
"discount": 0
}
},
{
"UID": "bbaa2923",
"quantity": 2,
"item": "pencil",
"DepartmentDomain": {
"type": "wood",
"departId": "11"
},
"PriceDomain": {
"Price": 7.00,
"taxA": 1.5175,
"discount": 1
}
}
],
"finalPrice": {
"totalTax": 13.50,
"total": 85.0
},
"MetaData": {
"shopId": "1405596346",
"locId": "95014",
"countryId": "USA",
"regId": "255",
"Date": "20180601"
}
}
')
This is what I am trying to achieve :
SELECT some_magic_fun(data_col,'Id,Domains.UID,Domains.DepartmentDomain.departId,finalPrice.total')::jsonb FROM my_jsonb_table;
I am trying to create that magic function which extracts the given keys in a jsonb format, as of now I am able to extract scalar items and put them in text[] and use jsonb_object. but don't know how can I extract all elements of array
expected output :
{
"Id": "20180601550002",
"Domains": [
{
"UID": "29aa2923",
"DepartmentDomain": {
"departId": "10"
}
},
{
"UID": "bbaa2923",
"DepartmentDomain": {
"departId": "11"
}
}
],
"finalPrice": {
"total": 85.0
}
}
I don't know of any magic. You have to rebuild it yourself.
select jsonb_build_object(
-- Straight forward
'Id', data_col->'Id',
'Domains', (
-- Aggregate all the "rows" back together into an array.
select jsonb_agg(
-- Turn each array element into a new object
jsonb_build_object(
'UID', domain->'UID',
'DepartmentDomain', jsonb_build_object(
'departId', domain#>'{DepartmentDomain,departId}'
)
)
)
-- Turn each element of the Domains array into a row
from jsonb_array_elements( data_col->'Domains' ) d(domain)
),
-- Also pretty straightforward
'finalPrice', jsonb_build_object(
'total', data_col#>'{finalPrice,total}'
)
) from my_jsonb_table;
This probably is not a good use of a JSON column. Your data is relational and would better fit traditional relational tables.
Hello Good Developers,
I am facing a situation in MongoDB where I've JSON Data like this
[{
"id": "GLOBAL_EDUCATION",
"general_name": "GLOBAL_EDUCATION",
"display_name": "GLOBAL_EDUCATION",
"profile_section_id": 0,
"translated": [
{
"con_lang": "US-EN",
"country_code": "US",
"language_code": "EN",
"text": "What is the highest level of education you have completed?",
"hint": null
},
{
"con_lang": "US-ES",
"country_code": "US",
"language_code": "ES",
"text": "\u00bfCu\u00e1l es su nivel de educaci\u00f3n?",
"hint": null
}...
{
....
}
]
I am projecting result using the following query :
db.collection.find({
},
{
_id: 0,
id: 1,
general_name: 1,
translated: {
$elemMatch: {
con_lang: "US-EN"
}
}
})
here's a fiddle for the same: https://mongoplayground.net/p/I99ZXBfXIut
I want those records who don't match $elemMatch don't get returned at all.
In the fiddle output, you can see that the second item doesn't have translated attribute, In this case, I don't want the second Item at all to be returned.
I am using Laravel as Backend Tech, I can filter out those records using PHP, but there are lots of records returned, and I think filtering using PHP is not the best option.
You need to use $elemMatch in the first parameter
db.collection.find({
translated: {
$elemMatch: {
con_lang: "IT-EN"
}
}
})

I'm using mongodb in laravel 5.1 and I had the following database structure for states colection:
{
"state_name": "XXXXX",
"districts": [
{
"district_id": "1",
"district_name": "AAAA"
},
{
"district_id": "2",
"district_name": "BBBBB"
},
{
"district_id": "3",
"district_name": "CCCC"
},
]}
I need to get the districts as list and set in laravel select tag. How can I write query to fetch the inner array records as lists and set in laravel select tag?
Please help.
Thanks
