mysql transaction error handling

Question

 DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING, NOT FOUND 
BEGIN 
    ROLLBACK; 
END;
START TRANSACTION;      

    UPDATE tbl_order SET TransactionID="abc" WHERE OrderID=1;
    UPDATE tbl_order SET TransactionID="xyz" WHERE OrderID=;
    UPDATE tbl_order SET TransactionID="zzz" WHERE OrderID=13;


COMMIT;

for some reason order 1 and 13 are filled without rollback and i get syntax error for the exit hadler.

Query:  DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING, NOT FOUND BEGIN ROLLBACK

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 'DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING, NOT FOUND 
BEGIN 
    ROLLBACK' at line 1

can someone help me figure out what i'm doing wrong?

Thanks in advance

EDIT

UPDATE tbl_order SET TransactionID="xyz" WHERE OrderID=;

is intentional

I believe exit handlers can only be used in stored procedures. The documentation doesn't explicitly state this, but alludes to

Conditions may arise during stored program execution that require special handling
