    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.
