我用Dreamweaver做删除页面,在删除记录出现问题。

aijames 2009-11-24 04:54:04
现在我出现的情况我也说不清楚,我举例子吧。
一间学校A班有个同学叫小明,C班也有个小明,现在在dreamweaver的修改页中想对A班的小明记录进行修改,但修改确认后,连C班小明的记录也修改了。我现在的情况就是这样,有哪位高手帮忙看看是要对哪里修改??

修改数据记录的时候最好以ID作为条件
[/Quote]
他的意思就是类似这样的
<a href="edit.asp?id=<%=rs("id")%>">修改</a> <a href="delete.asp?id=<%=rs("id")%>">删除</a>

不过实际情况跟班级学生有一点区别,我这页面联系的数据库,它今次购入A类棉3000KG,下次又购入5000KG,两者都是同一样物品,商品编码都一样,但它这样就出现现在的问题。
还有更好的建议吗?

我想达到的效果是,我修改A班小明记录,B班的小明的记录不受影响。


数据库的存放形式是,一个表中存放所有班级,所有学生的信息。

现在修改A班的小明,连B班的小明也转班了,搞到A班有两个小明,有什么方法限制这样的情况?

MM_editQuery = "delete from " & MM_editTable & " where " & MM_editColumn & " = " & MM_recordId

where后面 不能这样写哟
全部给一个变量吧

比如MM_editColumn="id=5"
不要分开写

把最后执行的sql语句显示出来 把delete 改成 select 看下查出来的数据 应该是sql语句的条件有问题吧
