Answer 1

You need to temporarily change the delimiter so the MySQL client doesn't think you're done with your statement when it sees the semicolon on line 3:

DELIMITER //

CREATE PROCEDURE dorepeat(IN p1 INT)
BEGIN
  DECLARE x INT DEFAULT 0;
  REPEAT SET x = x + 1; UNTIL x > p1 END REPEAT;
END//

DELIMITER ;
