SQLite JSON_OBJECT function

The SQLite json_object() function is a powerful feature that allows you to create a JSON object from one or more key-value pairs in SQLite. This function was introduced in SQLite version 3.9.0 and has since become a popular tool for developers working with JSON data in SQLite.


The basic syntax of the json_object() function is as follows:

json_object(key1, value1, key2, value2, …)

The function takes any number of key-value pairs as arguments and returns a JSON object. Each key and value pair is separated by a comma, and the entire list of key-value pairs is enclosed in parentheses.


Here is an example of how the json_object() function can be used in an SQLite query:

SELECT json_object('name', 'John', 'age', 30);

This query will return a JSON object with two key-value pairs: “name” : “John” and “age” : 30. The resulting JSON object looks like this:

    "name": "John",
    "age": 30

You can also use the json_object() function with other SQLite functions and expressions. For example, you can use the json_object() function to create a JSON object that includes the result of another SQL query:

json_object('name', name, 'age', age) 
FROM users 
WHERE id = 1;

In this example, we’re selecting the “name” and “age” fields from the “users” table and passing them as arguments to the json_object() function. This will create a JSON object with two key-value pairs, which will be returned as a result of the query.

Overall, the json_object() function is a useful tool for working with JSON data in SQLite. It makes it easy to create JSON objects from key-value pairs and can be combined with other SQL expressions and functions to create more complex queries.
