Sytax error in mysql stored procedure - mysql

Question

What is wrong in the syntax of the below stored procedure in MySQL ?
CREATE PROCEDURE curdemo()
BEGIN
DECLARE #isbn varchar(17)
DECLARE #count int
DECLARE #price float(6,2)
DECLARE #totalbookpriceValue float(6,2)
DECLARE totalbookprice CURSOR
STATIC FOR
(SELECT ISBN,COUNT(ISBN) FROM applieddb.cart c GROUP BY ISBN)
OPEN totalbookprice
IF ##CURSOR_ROWS > 0 BEGIN
FETCH NEXT FROM cur_emp INTO #isbn,#count
WHILE ##Fetch_status = 0
SELECT ISBN,PRICE FROM book INTO #price WHERE ISBN = #isbn
PRINT 'Total Book Price is' + #price * #count
FETCH NEXT FROM cur_emp INTO #isbn,#count
END
END
CLOSE totalbookprice
DEALLOCATE totalbookprice
SET NOCOUNT OFF
END
ERROR Message:
Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '#isbn varchar(17) DECLARE #count int DECLARE #price float(6,2) DECLARE #totalboo' at line 3
Changing the mysql query to the below also did not help and gave the following error:

Answer 1

DECLARE for local (without #) or SET for session (with #)

Answer 2

***The solution to the above problem is as below:***
CREATE DEFINER=`root`#`localhost` PROCEDURE `calculateTotalPrice`()
BEGIN
DECLARE done INT default 0;
DECLARE _isbn varchar(17);
DECLARE _count int;
DECLARE _price float(6,2);
DECLARE loop_cntr INT DEFAULT 0;
DECLARE _totalbookpriceValue float(6,2);
DECLARE totalbookprice CURSOR FOR SELECT ISBN,COUNT(ISBN) FROM applieddb.cart c GROUP BY ISBN;
DECLARE CONTINUE HANDLER FOR NOT FOUND set done= TRUE;
OPEN totalbookprice;
the_loop: LOOP
FETCH totalbookprice into _isbn,_count;
SET _price= (SELECT b.price from book b where b.ISBN = _isbn);
SET _totalbookpriceValue= _price*_count;
SELECT _totalbookpriceValue;
IF done THEN
CLOSE totalbookprice;
LEAVE the_loop;
END IF;
-- count the number of times looped
SET loop_cntr = loop_cntr + 1;
END LOOP the_loop;
END
