JSON in Oracle

 JSON in Oracle

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is used to transmit data between servers and web applications. Oracle Database supports the storage and retrieval of JSON data using JSON data types and functions. Here is an example:

CREATE TABLE employees (

   employee_id NUMBER(10),

   employee_info CLOB CHECK (employee_info IS JSON)

);

This creates a table named "employees" that has a column named "employee_info" of type CLOB that is constrained to contain only JSON data.
