菜鸟学ADO实例教程之ADO 显示数据
类别: ASP教程 
从数据表中读出数据通常是显示在 HTML 的表格中的。下面介绍四种常用的显示数据的方法：
首先给大家介绍一点有关数据库表Customers的内容，数据库表中有如下字段：CustomerID(客户号)、 CompanyName(公司名) 、ContactName(联系人)、ContactTitle(联系方式)、Address(地址)、City(城市)、 PostalCode(邮编) 、Country(国家)
并且我们可以事先随便输入一些值，使用下面代码时要注意数据库的路径。
1.显示字段名和字段值：
<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
do until rs.EOF
for each x in rs.Fields
Response.Write(x.name)
Response.Write(" = ")
Response.Write(x.value & "<br />")
next
Response.Write("<br />")
rs.MoveNext
loop
rs.close
conn.close
%>
</body>
</html>
2.把结果显示到表格中：
<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 Companyname, Contactname from Customers", conn
%>
<table border="1" width="100%">
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%></td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close
%>
</table>
</body>
</html>
给表格添加一个标题的显示方式：
<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")
sql="SELECT Companyname, Contactname FROM Customers"
rs.Open sql, conn
%>
<table border="1" width="100%">
<tr>
<%for each x in rs.Fields
response.write("<th>" & x.name & "</th>")
next%>
</tr>
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%></td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close
%>
</table>
</body>
</html>
4.给表格加点背景的显示方法：
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("e:/webjx/webjx.mdb"))
set rs = Server.CreateObject("ADODB.recordset")
sql="SELECT Companyname, Contactname FROM Customers"
rs.Open sql, conn
%>
<table border="1" width="100%" bgcolor="#fff5ee">
<tr>
<%for each x in rs.Fields
response.write("<th align=\'left\' bgcolor=\'#b0c4de\'>" & x.name & "</th>")
next%>
</tr>
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%></td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close
%>
</table>
</body>
</html>
你可以试试上面的方法，因为本站没提供使用的是PHP主机所以没法测试了。
