    Description

      I run this script, it correctly returns an "Unknown system variable" error:

      DELIMITER $$
      		 
      BEGIN NOT ATOMIC
      		 
        SET GLOBAL a=10;
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;


      ERROR 1193 (HY000): Unknown system variable 'a'

      Now I modify the script slightly: additionally declare a local variable with name a:

      DELIMITER $$
      		 
      BEGIN NOT ATOMIC
      		 
        DECLARE a INT;
      		 
        SET GLOBAL a=10;
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;


      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 ';

      The error message looks confusing. The expected error message would be to return "Unknown system variable".
