ADO 显示

显示来自记录集中的数据的最常用的方法,就是把数据显示在 HTML 表格中。

显示记录

如何首先创建一个数据库连接,然后创建一个记录集,然后把其中的数据显示在HTML中。

<html>
<body>

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("/db/northwind.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>

在 HTML 表格中显示记录

如何把数据表中的数据显示在HTML表格中。


<html>
<body>

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("/db/northwind.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>

向 HTML 表格添加标题

如何向HTML表格添加标题,以使其可读性更强。

<html>
<body>

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("/db/northwind.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>

向 HTML 表格添加颜色

如何向HTML表格添加颜色,以使其更加美观。

<html>
<body>

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("/db/northwind.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>

显示字段名称和字段值

我们有一个名为 "Northwind" 的数据库,并且我们希望显示出 "Customers" 表中的数据(记得以 .asp 为扩展名来保存这个文件):

<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

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>

在一个 HTML 表格中显示字段名称和字段的值

我们也可以通过下面的代码把表 "Customers" 中的数据显示在一个 HTML 表格中:

<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 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>

向 HTML 表格添加标题

我们希望为这个 HTML 表格添加标题,这样它就更易读了:

<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")
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>
