asp修改数据问题
我在对数据库内数据进行修改时,当输入的原始内容为汉字或字母时,则无法进行修改,且不报错,原始内容为数字时,可以完成修改.请问为什么会出现这样的情况?

managecz.asp代码如下:


<%
dim cls
if session( "admin ")= " " then
Response.Redirect( "admin.asp ")
else
if session( "flag ") <> "0 " then

cls = Instr(session( "flag "), "danweifig ")
if cls <= 0 then
%>
<script language= "javascript ">
if (confirm( "您的操作权限不够,系统拒绝你的访问,请点确定返回,或者点取消退出重新登录 "))
location.href= "login.asp ";
else
location.href= "index.asp ";
</script>
<%
end if
end if
end if
%>

{
return ((event.keyCode > = 48) && (event.keyCode <= 57));
}

[解决办法]
检查一下数据库字段类型
[解决办法]
看看数据库相应的字段类型是什么？如果是数字的话，字母和汉字当然无法录入
[解决办法]
数据库类型问题
[解决办法]
对啊，这样的问题应该首先检查sql语句是不是错了，先用vb做个小测试，如果不错，然后看代码！
[解决办法]
把
conn.execute( "update caizhi set danweiorder= "&danweiorder& ",danweiname= "&danweiname& ",danjia= "&danjia& " where id= "&danweiid) ‘ " "这个代表的是数字
改成
conn.execute( "update caizhi set danweiorder= ' "&danweiorder& " ',danweiname= ' "&danweiname& " ',danjia= ' "&danjia& " ' where id= "&danweiid)’ ' " " '这个才是汉字和字母
[解决办法]
接点分
[解决办法]
唉!
只剩下接分了
[解决办法]
都解决了。。。我也来接点分吧
[解决办法]
conn.execute( "update caizhi set danweiorder= "&danweiorder& ",danweiname= "&danweiname& ",danjia= "&danjia& " where id= "&danweiid)
这个要改成
conn.execute( "update caizhi set danweiorder= ' "&danweiorder& " ',danweiname= ' "&danweiname& " ',danjia= ' "&danjia& " ' where id= "&danweiid)
