Get Data From Database as a JSON Object

SELECT JSON_ARRAYAGG(JSON_OBJECT("user_id", user_id, "user_name", user_name)) FROM ref_users;

SELECT JSON_OBJECT('name', user_name, 'phone', user_phone) FROM ref_users;

• These statements represent queries used in SQL (Structured Query Language). The first query uses the JSON_ARRAYAGG function to return the user_id and user_name columns from the table named ref_users as a JSON array. The second query uses the JSON_OBJECT function to return the user_name and user_phone columns from the same table as JSON objects.

• These queries can be used in many different scenarios. For example, you can use this type of query in a web application when you want to return user information in JSON format. The JSON format is a data exchange format that can easily transport and process data, so it is widely used, especially when exchanging data through APIs in web applications.

• These queries can be useful when you want to retrieve user information from a database in JSON format. For example, you can call a web service to return this JSON data and use it on the client side.
