ADO 添加記錄

ADO 添加記錄

ADO 添加記錄允許你添加有用的數(shù)據(jù)。

我們可以使用 SQL 的 INSERT INTO 命令向數(shù)據(jù)庫中的表添加記錄。

向數(shù)據(jù)庫中的表添加記錄

我們希望向 Northwind 數(shù)據(jù)庫中的 Customers 表添加一條新的記錄。我們首先要創(chuàng)建一個表單，這個表單包含了我們需要從中搜集數(shù)據(jù)的輸入域：

<html>
<body>

<form method="post" action="demo_add.html">
<table>
<tr>
<td>CustomerID:</td>
<td><input name="custid"></td>
</tr><tr>
<td>Company Name:</td>
<td><input name="compname"></td>
</tr><tr>
<td>Contact Name:</td>
<td><input name="contname"></td>
</tr><tr>
<td>Address:</td>
<td><input name="address"></td>
</tr><tr>
<td>City:</td>
<td><input name="city"></td>
</tr><tr>
<td>Postal Code:</td>
<td><input name="postcode"></td>
</tr><tr>
<td>Country:</td>
<td><input name="country"></td>
</tr>
</table>
<br><br>
<input type="submit" value="Add New">
<input type="reset" value="Cancel">
</form>

</body>
</html>

當用戶按下確認按鈕時，這個表單就會被送往名為 "demo_add.asp" 的文件。文件 "demo_add.asp" 中含有可向 Customers 表添加一條新記錄的代碼：

<html>
<body>

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"

sql="INSERT INTO customers (customerID,companyname,"
sql=sql & "contactname,address,city,postalcode,country)"
sql=sql & " VALUES "
sql=sql & "('" & Request.Form("custid") & "',"
sql=sql & "'" & Request.Form("compname") & "',"
sql=sql & "'" & Request.Form("contname") & "',"
sql=sql & "'" & Request.Form("address") & "',"
sql=sql & "'" & Request.Form("city") & "',"
sql=sql & "'" & Request.Form("postcode") & "',"
sql=sql & "'" & Request.Form("country") & "')"

on error resume next
conn.Execute sql,recaffected
if err<>0 then
Response.Write("No update permissions!")
else
Response.Write("<h3>" & recaffected & " record added</h3>")
end if
conn.close
%>

</body>
</html>
