Extract sub JSON with keys and values in MYSQL - mysql

Question

I have a table with a JSON TYPE column like this:
id
json_info
date
1.
{"Ccclaptop_model": {"value": "asus", "price": "2122"}, "laptop_ram": {"value": "6", "price": "122"}, "laptop_mouse_model": {"value": "logic", "price": "30"} , "laptop_keys_model": {"value": "USA", "price": "10"}}
2020-02-02
And I'd like to have a query that extracts a sub-JSON with his key value, like this:
id
json_info
date
1.
{"laptop_mouse_model": {"value": "logic", "price": "30"} , "laptop_keys_model": {"value": "USA", "price": "10"}}
2020-02-02
I have tried JSON_EXTRACT
SELECT id,
JSON_EXTRACT(json_info, '$.laptop_mouse_model', '$.laptop_keys_model' ) AS store_id
FROM feature_data WHERE date = '2020-02-02';
but just return a JSON array without keys, like this:
id
json_info
date
1.
[{"value": "logic", "price": "30"} ,{"value": "USA", "price": "10"}]
2020-02-02
Does somebody know if exists a function that I could use?

You can use JSON_OBJECT to combine result to a json, for example:
SELECT id,JSON_OBJECT('laptop_mouse_model',JSON_EXTRACT(json_info, '$.laptop_mouse_model'),'laptop_keys_model',JSON_EXTRACT(json_info, '$.laptop_keys_model')) AS store_id FROM feature_data WHERE date = '2020-02-02';
