    Description

      The task MDEV-10914 implements the ROW data type for stored routine local variables and parameters.

      This task will additionally allow to use ROW in stored function return data type.

      DROP FUNCTION IF EXISTS f1;
      		 
      DELIMITER $$
      		 
      CREATE FUNCTION f1(a INT, b VARCHAR(32)) RETURNS ROW(a INT, b VARCHAR(32))
      		 
      BEGIN
      		 
        RETURN ROW(a,b);
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;
      		 
      SELECT f1(1,'b1') = ROW(1,'b1');

      Anchored row data types should also be supported:

      DROP FUNCTION IF EXISTS f1;
      		 
      DELIMITER $$
      		 
      CREATE FUNCTION f1(a INT, b VARCHAR(32)) RETURNS ROW TYPE OF t1
      		 
      BEGIN
      		 
        RETURN ROW(a,b);
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;
      		 
      SELECT f1(1,'b1') = ROW(1,'b1');
