 Description   

This script works fine in Oracle:

BEGIN
 
FOR i IN (1)..(2)
 
LOOP
 
  NULL;
 
END LOOP;
 
END;
 
/

An equivalent script in MariaDB fails on error:

SET sql_mode=ORACLE;
 
DELIMITER /
 
BEGIN
 
FOR i IN (1)..(2)
 
LOOP
 
  NULL;
 
END LOOP;
 
END;
 
/


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 '1)..(2)

Another example script that works in Oracle but an equivalent script fails in MariaDB:

BEGIN
 
  FOR a IN (1)+1..3
 
  LOOP
 
    NULL;
 
  END LOOP;
 
END;
