    Description

      The task MDEV-10577 implemented anchored data types for stored routine local variables and parameters.

      • TYPE OF, for sql_mode=DEFAULT
      • %TYPE, for sql_mode=ORACLE

      This task will additionally allow to use anchored data types as stored function return data types:

      SET sql_mode=DEFAULT;
      		 
      DROP TABLE t1;
      		 
      DROP FUNCTION f1;
      		 
      CREATE TABLE t1 (a INT);
      		 
      DELIMITER /
      		 
      CREATE FUNCTION f1() RETURNS TYPE OF t1.a RETURN 0;
      		 
      BEGIN
      		 
        RETURN 0;
      		 
      END;
      		 
      /
      		 
      DELIMITER ;
      		 
      SELECT f1() FROM DUAL;


      SET sql_mode=ORACLE;
      		 
      DROP TABLE t1;
      		 
      DROP FUNCTION f1;
      		 
      CREATE TABLE t1 (a INT);
      		 
      DELIMITER /
      		 
      CREATE FUNCTION f1 RETURN t1.a%TYPE
      		 
      AS
      		 
      BEGIN
      		 
        RETURN 0;
      		 
      END;
      		 
      /
      		 
      DELIMITER ;
      		 
      SELECT f1() FROM DUAL;
