There is no direct method to retrieve JSON data from a column in SQL. However, some databases do have built-in functions or tools that allow you to parse and manipulate JSON data. For example, in MySQL you can use the JSON_EXTRACT() function to extract values from a JSON document stored in a column. In PostgreSQL, you can use the JSONB data type and its associated functions to manipulate JSON data stored in a column. Alternatively, you can use a programming language like Python or Java to connect to the SQL database and retrieve the JSON data through an API.
