<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 > 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

已解决,是代码有遗漏,末尾缺少斜杠
