Query a JSONB object array - json

Question

I did a DB Fiddle of what the table is kinda looking like https://www.db-fiddle.com/f/4jyoMCicNSZpjMt4jFYoz5/3382
Data in the table looks like this
[
{
"id": 1,
"form_id": 1,
"questionnaire_response": [
{
"id": "1",
"title": "Are you alive?",
"value": "Yes",
"form_id": 0,
"shortTitle": "",
"description": ""
},
{
"id": "2",
"title": "Did you sleep good?",
"value": "No",
"form_id": 0,
"shortTitle": "",
"description": ""
},
{
"id": "3",
"title": "Whats favorite color(s)?",
"value": [
"Red",
"Blue"
],
"form_id": 0,
"shortTitle": "",
"description": ""
}
]
},
{
"id": 2,
"form_id": 1,
"questionnaire_response": [
{
"id": "1",
"title": "Are you alive?",
"value": "Yes",
"form_id": 0,
"shortTitle": "",
"description": ""
},
{
"id": "2",
"title": "Did you sleep good?",
"value": "Yes",
"form_id": 0,
"shortTitle": "",
"description": ""
},
{
"id": "3",
"title": "Whats favorite color(s)?",
"value": "Black",
"form_id": 0,
"shortTitle": "",
"description": ""
}
]
},
{
"id": 3,
"form_id": 1,
"questionnaire_response": [
{
"id": "1",
"title": "Are you alive?",
"value": "Yes",
"form_id": 0,
"shortTitle": "",
"description": ""
},
{
"id": "2",
"title": "Did you sleep good?",
"value": "No",
"form_id": 0,
"shortTitle": "",
"description": ""
},
{
"id": "3",
"title": "Whats favorite color(s)?",
"value": [
"Black",
"Red"
],
"form_id": 0,
"shortTitle": "",
"description": ""
}
]
}
]
I have a query select * from form_responses,jsonb_to_recordset(form_responses.questionnaire_response) as items(value text, id text) where (items.id = '3' AND items.value like '%Black%');
But unable to do more than one object like select * from form_responses,jsonb_to_recordset(form_responses.questionnaire_response) as items(value text, id text) where (items.id = '3' AND items.value like '%Black%') AND (items.id = '2' AND items.value like '%Yes%');
The value field in the object could be an array or a single value also.. unpredictable.. I feel like I'm close but also not sure if im using the correct query in the first place.
Any help would be appreciated!
EDIT
select * from form_responses where(
questionnaire_response #> '[{"id": "2", "value":"No"},{"id": "3", "value":["Red"]}]')
Seems to work but not sure if this is the best way to do it

Answer 1

Your current query returns one result row per item. None of these rows has both id = 3 and id = 2. If your goal is to select the entire form response, you need to use a subquery (or rather, two of them):
SELECT *
FROM form_responses
WHERE EXISTS(
SELECT *
FROM jsonb_to_recordset(form_responses.questionnaire_response) as items(value text, id text)
WHERE items.id = '3'
AND items.value like '%Black%'
)
AND EXISTS(
SELECT *
FROM jsonb_to_recordset(form_responses.questionnaire_response) as items(value text, id text)
WHERE items.id = '2'
AND items.value like '%Yes%'
);
or alternatively
SELECT *
FROM form_responses
WHERE (
SELECT value
FROM jsonb_to_recordset(form_responses.questionnaire_response) as items(value text, id text)
WHERE items.id = '3'
) like '%Black%'
AND (
SELECT value
FROM jsonb_to_recordset(form_responses.questionnaire_response) as items(value text, id text)
WHERE items.id = '2'
) like '%Yes%';
A nicer alternative would be using json path queries:
SELECT *
FROM form_responses
WHERE questionnaire_response ## '$[*]?(#.id == "1").value == "Yes"'
AND questionnaire_response ## '$[*]?(#.id == "3").value[*] == "Black"'
-- in one:
SELECT *
FROM form_responses
WHERE questionnaire_response ## '$[*]?(#.id == "1").value == "Yes" && $[*]?(#.id == "3").value[*] == "Black"'
The [*] even has the correct semantics for that sometimes-string-sometimes-array value. And if you know the indices of the items with those ids, you can even simplify to
SELECT *
FROM form_responses
WHERE questionnaire_response ## '$[0].value == "Yes" && $[2].value[*] == "Black"'
