Unexpected MYSQL syntax error

Question

I tried to create the SP using the code from the url below , however it display many syntax error. https://dev.mysql.com/doc/refman/5.7/en/cursors.html

CREATE PROCEDURE curdemo()
BEGIN
  DECLARE done INT DEFAULT FALSE;
  DECLARE a CHAR(16);
  DECLARE b, c INT;
  DECLARE cur1 CURSOR FOR SELECT id,data FROM test.t1;
  DECLARE cur2 CURSOR FOR SELECT i FROM test.t2;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

  OPEN cur1;
  OPEN cur2;

  read_loop: LOOP
    FETCH cur1 INTO a, b;
    FETCH cur2 INTO c;
    IF done THEN
      LEAVE read_loop;
    END IF;
    IF b < c THEN
      INSERT INTO test.t3 VALUES (a,b);
    ELSE
      INSERT INTO test.t3 VALUES (a,c);
    END IF;
  END LOOP;

  CLOSE cur1;
  CLOSE cur2;
END;

INT DEFAULT FALSE; this is the reason for syntax error change this to INT DEFAULT 0; — rocks

Change the delimiter before your procedure. For instance like this: delimiter || — juergen d

Change your delimiter first

delimiter ||
CREATE PROCEDURE curdemo()
BEGIN
 ...
END
||
delimiter ;

Otherwise the DB engine thinks your procedure definitions ends at the first ; which would make it incomplete.
