Querying and Analyzing JSON Data in Oracle SQL

Modern SQL: Querying JSON Data in Oracle Like a Pro

Overview: With more systems storing data in JSON format, Oracle's support for JSON functions is a game-changer. Introduce JSON_VALUE, JSON_TABLE, JSON_EXISTS, and how to use them in real scenarios. Example Query:

SQL> ed
  1  SELECT
  2      empno,
  3      ename,
  4      json_value(extra_info, '$.linkedin') AS linkedin_profile
  5  FROM
  6      emp
  7  WHERE
  8*     json_exists(extra_info, '$.linkedin');
SQL> /

Use Case: Extract social media profiles or preferences stored in a JSON column (e.g., extra_info) for analytics or personalization.
