I'm trying to SELECT objects base on the roles property values.
Example: Select all names where role is 1 //response would return danny
Query Statement:
SELECT JSON_EXTRACT(username,'$[*].name') FROM objects WHERE JSON_CONTAINS(username,'1','$[*].roles')
COLUMN: username (JSON)
[
{
"name":"jordan",
"roles":[1,2,5]
},
{
"name":"danny",
"roles":[1,4]
}
]
Question: Why isn't my statement returning just the first object containing the name danny?
Try the following:
SELECT *
FROM objects
WHERE JSON_CONTAINS(components, '1', '$.roles');

I have a MySQL column with below data:
{
"ids": [
"c9cfdecc-dfce-11eb-8c94-0ad691f61ea0",
"c9cfdecc-dfce-11eb-8c94-0ad691f61ea1",
"c9cfdecc-dfce-11eb-8c94-0ad691f61ea2"
]
}
How can I get records that matched with any requested string?
I tried below queries but no use:
SELECT * from test WHERE JSON_CONTAINS(fragments, '"c9cfdecc-dfce-11eb-8c94-0ad691f61ea1"', '$')
SELECT * from test WHERE JSON_CONTAINS(fragments, '"c9cfdecc-dfce-11eb-8c94-0ad691f61ea1"')
SELECT * from test WHERE JSON_SEARCH(fragments, 'one', "c9cfdecc-dfce-11eb-8c94-0ad691f61ea1")
In my PostgreSQL 11.6 table I have a json field app_settings with data on the following format:
{
"my_app": {
"features": {
"very_good_feature": true,
"awesome_feature": false,
"even_better_feature": true
}
}
}
I want to create a query that selects a list of feature names where the feature has the value true. So in the example above, I would like the result of the query simply to be 2 rows like this:
very_good_feature
even_better_feature
I can successfully select ALL the keys with the following query:
select
json_object_keys(app_settings ->'my_app' -> 'features') as k
from
my_table;
How can I write the where clause to only list the ones with true as value?
try with json_each_text:
select j.* from my_table
join lateral json_each_text(app_settings->'my_app'->'features') j(k, v) on true
where
j.v = 'true'
I have a SQL table called 'Interactions' and a column called Events that holds an array of JSON data. I am looking for any row where the Events json has any array with #odata.type = #Sitecore.XConnect.Goal
[
{
"#odata.type":"#Sitecore.XConnect.Collection.Model.PageViewEvent",
"CustomValues":[
],
"DefinitionId":"9326cb1e-cec8-48f2-9a3e-91c7dbb2166c",

What I am currently trying is this, but no results
select *
from [Interactions] I
where exists
(
select *
from openjson(I.Events,'$."#odata.type"')
where value = '#Sitecore.XConnect.Goal'
)
If I use this, I can get any row where the 1st item in the array #odata.type = #Sitecore.XConnect.Goal. This works. But I want it from any item in the array.
SELECT *
FROM [Interactions]
WHERE JSON_VALUE([Events], '$[0]."#odata.type"') = '#Sitecore.XConnect.Goal'
One possible approach is to parse the JSON column using OPENJSON() with explicit schema (WITH clause with columns definitions). With this approach you can filter the Interactions table and get information from the JSON data.
Table:
CREATE TABLE Interactions (
Events nvarchar(max)
)
INSERT INTO Interactions
(Events)
VALUES
(N'[
{
"#odata.type":"#Sitecore.XConnect.Collection.Model.PageViewEvent",
"CustomValues":[
],
"DefinitionId":"9326cb1e-cec8-48f2-9a3e-91c7dbb2166c",

"Id":"b067f72f-1d60-4773-a2e8-9d23770fea54",
"Timestamp":"2019-11-11T17:18:31.2206225Z",
"ItemLanguage":"en",
"ItemVersion":1,
"Url":"/renewal-confirmation",
"SitecoreRenderingDevice":{
"Id":"fe5d7fdf-89c0-4d99-9aa3-b5fbd009c9f3",
"Name":"Default"
}
},
{
"#odata.type":"#Sitecore.XConnect.Goal",
"CustomValues":[
],
"DataKey":"/sitecore/content/Client/home/renewal-confirmation",
"DefinitionId":"c0bc91b9-b5fc-4faa-bc12-3dba8bbae44f",
"ItemId":"5ae02a76-ac59-4dbb-913f-3b2e51d92bae",
"EngagementValue":100,
"Id":"e7031fb4-ce57-459f-a9f1-2682748d3431",

"Timestamp":"2019-11-11T17:18:31.2518732Z"
}
]')
Statement:
SELECT *
FROM Interactions i
CROSS APPLY OPENJSON(i.Events) WITH (
ODataType nvarchar(100) '$."#odata.type"'
-- and additional columns definitions
) j
WHERE j.ODataType = '#Sitecore.XConnect.Goal'
Your original query is close but doesn't work because you can't directly pick out scalars with OPENJSON. You want something like this:
SELECT *
FROM [interactions]
WHERE EXISTS (
SELECT 1
FROM OPENJSON([events]) WITH (
[#odata.type] NVARCHAR(MAX)
)
WHERE [#odata.type] = '#Sitecore.XConnect.Goal'
)
I need to capture rows when data inside a json field in mysql meets certain criteria. What select would I run to get the rows returned where the json column had a Status value of 1000 in any object in the array?
I tried using the something like this:
SELECT * FROM table WHERE Task_JSON->"$[0]" = 1000;
I'm using Server version: 5.7.11 of mysql
[
{
"Sequence":"1" ,
"Status":"1000"
},
{
"Sequence":"2" ,
"Status":"1000"
},
{
"Sequence":"3" ,
"Status":"3000"
}
]
You can use the following solution using JSON_CONTAINS:
SELECT *
FROM table_name
WHERE JSON_CONTAINS(Task_JSON, '{"Status":"1000"}') > 0;
Another solution using JSON_SEARCH:
SELECT *
FROM table_name
WHERE JSON_SEARCH(Task_JSON, 'one', '1000', NULL, '$[*]."Status"') IS NOT NULL;
demo: https://www.db-fiddle.com/f/3JTQreVi63FS7HbmWQ9TEM/4
SELECT * FROM table WHERE Task_JSON ->>'Status' = 1000;
JSON_EXTRACT can help you.
https://dev.mysql.com/doc/refman/8.0/en/json-search-functions.html
select * from table where JSON_EXTRACT(Task_JSON, '$.Status') = 1000 ;
I have this kind of json array and i want to check stringValue inside value array is null or not plus i want to check it with its id and fielddata is column name
[
{
"name": "50a5613e97e04cb5b8d32afa8a9975d1",
"value": {
"stringValue": null
}
},
{
"name": "bb127e8284c84692aa217539c4312394",
"value": {
"dateValue": 1549065600
}
}
]
query is:
select *
from field
WHERE (fielddata->>'name') = '50a5613e97e04cb5b8d32afa8a9975d1'
AND fielddata->'value'->>'stringValue' IS NOT NULL;
and I want use this query in laravel5.7
Try this
$result = \DB::table('field')->where('name', "50a5613e97e04cb5b8d32afa8a9975d1" )->where('value', $stringValue)->get();
if(isset($result)){
foreach($result as $res){
if(isset($res['value']->stringValue)){
// not null case
}else{
// null case
}
}
}
Within a SQL query, I think you want something like this:
select t.*
from the_table t
where exists (select *
from jsonb_array_elements(t.fielddata) as j(e)
where e ->> 'name' = '50a5613e97e04cb5b8d32afa8a9975d1'
and e -> 'value' ->> 'stringValue' is not null);
The exists sub-query will check every array element and see if at least one element has the specified name and a non-null stringValue. The query will then return the complete row from the table that fulfills the condition.
