我們可使用SQL的UPDATE來更新數(shù)據(jù)庫表中的某條記錄。
我們希望更新Northwind數(shù)據(jù)中Customers表的某條記錄。首先我們需要創(chuàng)建一個表格，來列出Customers中的所有記錄。
<html><body><%set conn=Server.CreateObject("ADODB.Connection")conn.Provider="Microsoft.Jet.OLEDB.4.0"conn.Open "c:/webdata/northwind.mdb"set rs=Server.CreateObject("ADODB.Recordset")rs.open "SELECT * FROM customers",conn%><h2>List Database</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_update.asp"><%for each x in rs.Fields if lcase(x.name)="customerid" then%> <td> <input type="submit" name="customerID" value="<%=x.value%>"> </td> <%else%> <td><%Response.Write(x.value)%></td> <%end ifnext%></form><%rs.MoveNext%></tr><%loopconn.close%></table></body></html> 如果用戶點擊"customerID"列中的按鈕，會打開一個新文件"demo_update.asp"。此文件包含了創(chuàng)建輸入域的源代碼，這些輸入域基于數(shù)據(jù)庫中記錄的字段，同時也含有一個保存修改的“更新按鈕”：
<html><body><h2>Update Record</h2><%set conn=Server.CreateObject("ADODB.Connection")conn.Provider="Microsoft.Jet.OLEDB.4.0"conn.Open "c:/webdata/northwind.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="Update record"> </form><%else sql="UPDATE customers SET " sql=sql & "companyname='" & Request.Form("companyname") & "'," sql=sql & "contactname='" & Request.Form("contactname") & "'," sql=sql & "address='" & Request.Form("address") & "'," sql=sql & "city='" & Request.Form("city") & "'," sql=sql & "postalcode='" & Request.Form("postalcode") & "'," sql=sql & "country='" & Request.Form("country") & "'" sql=sql & " WHERE customerID='" & cid & "'" on error resume next conn.Execute sql if err<>0 then response.write("No update permissions!") else response.write("Record " & cid & " was updated!") end if end ifconn.close%></body></html>分享：ASP在線問答的實例代碼首先，是HTML文件，為Test.asp，代碼如下：%@LANGUAGE=VBSCRIPT CODEPAGE=936% % if session(username)= then Response.Write(scriptalert('請登陸后在進(jìn)行操作！');window.location='login.asp?reURL=Test.asp';/script) Response.End() end if %
