    Description

      Function JSON_EXTRACT() in MariaDB 10.2.x don't support column->path and column->>path operators that are supported in MySQL since version 5.7.13.
      https://mariadb.com/kb/en/mariadb/json_extract

      More details about syntax and examples here.

      It work and in MySQL and in MariaDB.

      SELECT JSON_EXTRACT('{"id":"1", "name":"Name"}', '$.name') `name`;
      		 
      SELECT JSON_UNQUOTE(JSON_EXTRACT('{"id":"1", "name":"Name"}', '$.name')) `name`;

      It work only in MySQL.

      SELECT '{"id":"1", "name":"Name"}'->'$.name' `name`;
      		 
      SELECT '{"id":"1", "name":"Name"}'->>'$.name' `name`;

      https://dev.mysql.com/doc/refman/5.7/en/json-search-functions.html#operator_json-inline-path

      Because of this issue, I can't transparent migrate all my projects from MySQL to MariaDB.
