我开发了一个广告联盟程序，要实现扣量的功能。就是比如本来有100的点击量，设置扣量20%之后就只显示80个。但是现在有个问题，我修改了扣量比例之后，用户再去查询原来的数据就会变，比如用户昨天真实点击有100个，我设置扣20%，就显示80个，今天我设置扣30%，如果用户去查昨天的数据就会显示70个，这样肯定不对啊。求思路，谢谢。

回复讨论(解决方案)

问题还是没说明白，显示70不对那是要显示多少？100？

折扣和时间关联起来不就可以了吗

问题还是没说明白，显示70不对那是要显示多少？100？

根本就不能让用户知道被扣量了，昨天显示80，今天也应该显示80

最笨的方法就是建一个记录扣量比例 + 时间的表读取数据的时候根据当时的时间找到当时的扣量比例显示数据

应该有三个字段
1.真实数
2.显示给用户看的
3.扣除的
显示给用户的是2。
1，3只是内部知道就可以了。

这个似乎只有和时间相关联。然后要现实的时候去读取对应时间的扣量比例计算出要现实的数据。
