To extract JSON data from MySQL, you can make use of the JSON functions provided by MySQL. Here's an example of how you can do it:

  1. Retrieve JSON data directly from a JSON column: SELECT json_column_name FROM table_name;
  2. Extract specific values from a JSON column using the -> operator: SELECT json_column_name->"$.key" FROM table_name;
  3. Extract specific values from a JSON column using key names: SELECT json_column_name->'$.key_name' FROM table_name;
  4. Filter and extract data from a JSON column based on specific conditions: SELECT json_column_name->'$.key_name' FROM table_name WHERE json_column_name->'$.key_name' = 'value';


Remember to replace json_column_name with the actual name of the JSON column and table_name with the name of the table where the JSON data is stored.
