      Description

      DELIMITER $$
      SET @v=0;
      FOR a IN (SELECT 1) .. 3 DO SET @v = @v + a; END FOR;
      $$
      

      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 '.. 3 DO SET @v = @v + a; END FOR' at line 1
      

      If I use a subquery in the upper bound, it works fine:

      DELIMITER $$
      SET @v=0;
      FOR a IN 1 ..(SELECT 3) DO SET @v = @v + a; END FOR;
      SELECT @v;
      $$
      

      +------+
      | @v   |
      +------+
      |    6 |
      +------+
