    Description

      Compare:

      MariaDB 10.2

      MariaDB [test]> SELECT JSON_UNQUOTE('foo');
      +---------------------+
      | JSON_UNQUOTE('foo') |
      +---------------------+
      | NULL                |
      +---------------------+
      1 row in set (0.00 sec)
      

      MySQL 5.7

      MySQL [test]> SELECT JSON_UNQUOTE('foo');
      +---------------------+
      | JSON_UNQUOTE('foo') |
      +---------------------+
      | foo                 |
      +---------------------+
      1 row in set (0.00 sec)
      

      Note: MySQL might be not quite right about it either, as it's supposed to throw an error if the parameter is not a valid JSON document.
