以下代码可以运行,但批量修改数据不成功,不知错误在哪里

<!--#include file=include.asp-->
<%
Response.Buffer = True
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.Expires = 0
Response.CacheControl = "no-cache"

set rss=server.CreateObject("adodb.recordset")
sqls="select * from web_childorders Where Shopid='"&request.cookies("kkshopid")&"'"
rss.open sqls,conn,1,3
%>

<form name="orderChange" method="post" action="?act=update">
<table border="1" width="100%" id="table1">

<tr> <td>
<input type="submit" name="Submit3" value="Submit" onClick="return confirm('Confirm ?');">
</td></tr>
<tr> <td>Item Number</td> </tr>

<%
do while not rss.eof
    if rss("C_state")>0 then
%>
<tr><td><input type=checkbox name="ck" value=<%=rss("orderid")%>> <%=rss("orderid")%> </td></tr>
<%
    End if
    rss.movenext
loop
%>
</table>
</form>

<%
if request("act")="update" and request("ck")<>"" then

    ''第一种方法,改不了任何数据
     ''conn.execute("update web_childorders set C_state=6 where orderid in ('"&request("ck")&"')")

''第二种方法,只改第一个数据
pid=request("ck")
mystr=split(pid,",")
for i=0 to ubound(mystr)
exec="update web_childorders set C_state=6 where orderid ='"&mystr(i)&"'"
conn.execute(exec)
next
    response.write("Records has been updated")
end if

set rss=nothing
conn.close
set conn = Nothing
%>

conn.execute("update web_childorders set C_state=6 where orderid in ('"&request("ck")&"')")
更新数据必须确定性指名数据是哪条用=号，而你这个SQL用的确是非确定性的in.

第二条，如果只更新了一条记录，先检查一下你的数据有效性

数据库表名: web_childdorders

数据库结构：

orderid        Shopid        C_state
123        abc        1
456        abc        1
789        def        1

数据都有效,但只能更新第一条记录

我是说这个
for i=0 to ubound(mystr)
和这个：
where orderid ='"&mystr(i)&"'"

''conn.execute("update web_childorders set C_state=6 where orderid in ('"&request("ck")&"')")
我觉得不要用引号试试！
''conn.execute("update web_childorders set C_state=6 where orderid in ("&request("ck")&")")

不用引号会出现

用response.write 会显示正确的记录,数据都是有效的

''第二种方法,只能改第一个数据
pid=request("ck")
mystr=split(pid,",")
for i=0 to ubound(mystr)
exec="update web_childorders set C_state=6 where orderid ='"&mystr(i)&"'"
conn.execute(exec)

''用response.write 会显示正确的记录
response.write (mystr(i)&"<br>")

next

sql 语句 "update web_childorders set C_state=6 where orderid in ('1011042253179022','10112810593074851')"
成功批量修改数据库

不知道是不是
<tr><td><input type=checkbox name="ck" value=<%=rss("orderid")%>> <%=rss("orderid")%> </td></tr>
取的是数字,而数据库里的是字符而出现问题?
