菜鸟学ADO实例教程之ADO 删除记录
类别: ASP教程 
我们可以使用SQL DELETE命令来删除表中的一个记录，和添加记录的方法一样，首先列出记录内容
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "e:/webjx/webjx.mdb"
set rs=Server.CreateObject("ADODB.Recordset")
rs.open "SELECT * FROM customers",conn
%>
<h2>数据库的内容列表</h2>
<table border="1" width="100%">
<tr>
<%
for each x in rs.Fields
response.write("<th>" & ucase(x.name) & "</th>")
next
%>
</tr>
<% do until rs.EOF %>
<tr>
<form method="post" action="demo_delete.asp">
<%
for each x in rs.Fields
if x.name="customerID" then%>
<td>
<input type="submit" name="customerID" value="<%=x.value%>">
</td>
<%else%>
<td><%Response.Write(x.value)%></td>
<%end if
next
%>
</form>
<%rs.MoveNext%>
</tr>
<%
loop
conn.close
%>
</table>
</body>
</html>
具体的删除程序：demo_delete.asp
<html>
<body>
<h2>Delete Record</h2>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "e:/webjx/webjx.mdb"
cid=Request.Form("customerID")
if Request.form("companyname")="" then
set rs=Server.CreateObject("ADODB.Recordset")
rs.open "SELECT * FROM customers WHERE customerID=\'" & cid & "\'",conn
%>
<form method="post" action="demo_update.asp">
<table>
<%for each x in rs.Fields%>
<tr>
<td><%=x.name%></td>
<td><input name="<%=x.name%>" value="<%=x.value% >"></td>
<%next%>
</tr>
</table>
<br /><br />
<input type="submit" value="删除记录">
</form>
<%
else
sql="DELETE FROM customers"
sql=sql & " WHERE customersID=\'" & cid & "\'"
on error resume next
conn.Execute sql
if err<>0 then
response.write("No update permissions!")
else
response.write("Record " & cid & " was deleted!")
end if
end if
conn.close
%>
</body>
</html>
教程就写到这里，希望对初学ASP的朋友有所帮助，我就感到欣慰了，同时希望高手给指点。
