MySQL problem using CREATE FUNCTION in cPanel - mysql

Question

I have been receiving always an error while creating mysql function in cpanel with below code.
But the below code is running properly while creating mysql function in SQL Manger 2007.
Anyone tell me what is wrong with this code for cpanel.
ERROR :- 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 '' at line 12
(0.81 sec)
CREATE FUNCTION F_test (topsbwynum INTEGER)
RETURNS float(20,2)
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
BEGIN
DECLARE FinalPrice VARCHAR(20);
DECLARE err VARCHAR(20);
DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET err = 1;
IF(sbwynum > 0)THEN
IF(FinalPrice > 0)THEN
RETURN FinalPrice;
ELSEIF(adjprice > 0)THEN
RETURN adjprice;
ELSEIF(price > 0)THEN
RETURN price;
ELSEIF(estprice > 0)THEN
RETURN estprice;
ELSE
RETURN 0;
END IF;
ELSE
RETURN 0;
END IF;
END;
Thanks a lot.

For multi-line statements, you can't use the same character (";", by default) to delimit the individual statements within the function definition and the entire CREATE statement. If you try, the creation statement ends at the first ";" (in the sample code, it's after the first DECLARE). Since the statement syntax error is at the end of the truncated statement, the error message gives '' as the part of the statement where the error occurs.
From the command line client, you'd use the delimiter command to change the delimiter used by the client to (e.g.) ";;", then end the creation statement with this delimiter:
delimiter ;;
CREATE FUNCTION F_test (topsbwynum INTEGER)
...
END;;
delimiter ;
In phpMyAdmin, there's a "delimiter" field that fulfills the same purpose.
