这段mysql存储过程是否有错误？

<code>DELIMITER //
create procedure largest_order(out largest_id int)
BEGIN
    declare this_id int;
    declare this_amount float;
    declare l_amount float default 0.0;
    declare l_id int;

    declare done int default 0;
    declare c1 cursor for select orderid,amount from orders;
    declare continue handler for SQLSTATE '02000' set done = 1;
    
    
    open c1;
    repeat 
        fetch c1 into this_id,this_amount;
        if not done THEN
            if this_amount &gt; l_amount THEN
                set l_amount=this_amount;
                set l_id=this_id;
            end IF;
        end if;
    until done end repeat;
    close c1;
    set largest_id = l_id;
END
//
DELIMITER ;</code>

代码如上,在navicat报错

回复内容：

<code>DELIMITER //
create procedure largest_order(out largest_id int)
BEGIN
    declare this_id int;
    declare this_amount float;
    declare l_amount float default 0.0;
    declare l_id int;

    declare done int default 0;
    declare c1 cursor for select orderid,amount from orders;
    declare continue handler for SQLSTATE '02000' set done = 1;
    
    
    open c1;
    repeat 
        fetch c1 into this_id,this_amount;
        if not done THEN
            if this_amount &gt; l_amount THEN
                set l_amount=this_amount;
                set l_id=this_id;
            end IF;
        end if;
    until done end repeat;
    close c1;
    set largest_id = l_id;
END
//
DELIMITER ;</code>

已解决，是代码有遗漏，末尾缺少斜杠
