    Description

      Hopefully it is closely related to MDEV-25254 and will be fixed by the same patch, but I'm not quite sure about that.

      The query works in MariaDB:

      bb-10.6-mdev17399-hf 8611fb30b

      		 
      SELECT * FROM
      		 
      JSON_TABLE('[]', '$' COLUMNS(a TEXT PATH '$[*]')) AS jt1
      		 
        RIGHT JOIN JSON_TABLE(jt1.a, '$' COLUMNS(o2 FOR ORDINALITY)) AS jt2
      		 
          ON(1)
      		 
        RIGHT JOIN JSON_TABLE('[]', '$' COLUMNS(o3 FOR ORDINALITY)) AS jt3
      		 
          ON(1)
      		 
      WHERE 0;


      MariaDB [test]> SELECT * FROM
      		 
          -> JSON_TABLE('[]', '$' COLUMNS(a TEXT PATH '$[*]')) AS jt1
      		 
          ->   RIGHT JOIN JSON_TABLE(jt1.a, '$' COLUMNS(o2 FOR ORDINALITY)) AS jt2
      		 
          ->     ON(1)
      		 
          ->   RIGHT JOIN JSON_TABLE('[]', '$' COLUMNS(o3 FOR ORDINALITY)) AS jt3
      		 
          ->     ON(1)
      		 
          -> WHERE 0;
      		 
      Empty set (0.001 sec)

      But when it is executed via a view, it complains about invalid tables/columns:

      MariaDB [test]> CREATE VIEW v AS
      		 
          -> SELECT * FROM
      		 
          -> JSON_TABLE('[]', '$' COLUMNS(a TEXT PATH '$[*]')) AS jt1
      		 
          ->   RIGHT JOIN JSON_TABLE(jt1.a, '$' COLUMNS(o2 FOR ORDINALITY)) AS jt2
      		 
          ->     ON(1)
      		 
          ->   RIGHT JOIN JSON_TABLE('[]', '$' COLUMNS(o3 FOR ORDINALITY)) AS jt3
      		 
          ->     ON(1)
      		 
          -> WHERE 0;
      		 
      Query OK, 0 rows affected (0.015 sec)
      		 
       
      		 
      MariaDB [test]> 
      MariaDB [test]> SELECT * FROM v;
      		 
      ERROR 1356 (HY000): View 'test.v' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them

      In MySQL both the query and CREATE VIEW fail with ER_BAD_FIELD_ERROR:

          ->   RIGHT JOIN JSON_TABLE('[]', '$' COLUMNS(o3 FOR ORDINALITY)) AS jt3
      		 
          ->     ON(1)
      		 
          -> WHERE 0;
