    Description

      Upon a missing mandatory JSON table alias, MariaDB produces the generic syntax error ER_PARSE_ERROR:

      bb-10.6-mdev17399-psergey2 8b533cc1d5

      		 
      MariaDB [db]> select * from json_table('[]', '$' COLUMNS(x FOR ORDINALITY));
      		 
      ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 1

      while MySQL returns a nicer context-specific error:

      MySQL 8.0.23

      		 
      MySQL [db]> select * from json_table('[]', '$' COLUMNS(x FOR ORDINALITY));
      		 
      ERROR 3667 (42000): Every table function must have an alias

      It is a cosmetic problem, but deep within a more complicated query it can become confusing.
