紧急求助：用游标取数来更新某一列的问题
如果来实现这种功能，第一行余额为37000,第二行的余额＝37000＋收款0－发出金额9000＝28000,也就是余额是累加的。我写了一个存储过程，取出来的数不对，是把临时表里取到的所有的客户的余额都累加了。还望高手指点啊。

有没有列（或者id）能判断这条记录是第几行？比如第一行id就是1，第二行的id是2或者一定比1大？依此类推，如果不能那可以加一个标识列，我感觉从你的“如果来实现这种功能，第一行余额为37000,第二行的余额＝37000＋收款0－发出金额9000＝28000,也就是余额是累加的。”这段话的描述来说不需要使用游标（当然是我前面说的情况成立），用关联子查询
update tb set tb.result = (select sum(b.收款-b.发出金额) where b.id >= tb.id)
大概就是这么个意思。
