ASP实例：利用缓存提高数据显示效率

实例演示.先建立一个简单的数据库,写个function读取一下,写入一个dim变量temp中:

ASP代码

<%       
Function DisplayRecords()       
    Dim sql, conn, rs       
    sql = "SELECT id, [szd_f], [szd_t] FROM admin"      
    Set conn = Server.CreateObject("ADODB.Connection")       
    conn.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ="&Server.MapPath("db.mdb")       
    Set rs = Server.CreateObject("ADODB.Recordset")       
    rs.Open sql, conn, 1, 3
    If Not rs.EOF Then      
      Dim temp       
      temp = "<table width=""90%"" align=""center"""      
      temp = temp & " border=""1""  bordercolor=""silver"""      
      temp = temp & " cellspacing=""2"" cellpadding=""0"">"      
      temp = temp & "<tr bgcolor=""#CCDDEE""><td width=""5%"""      
      temp = temp & ">ID</td><td>操作</td>"
      temp = temp & "<td>数值</td></tr>"
    While Not rs.EOF       
      temp = temp & "<tr><td bgcolor=""#CCDDEE"">"      
      temp = temp & rs("ID") & "</td><td>" & rs("szd_f")       
      temp = temp & "</td><td>" & rs("szd_t")       
      temp = temp & "</td></tr>"      
      rs.MoveNext       
    Wend
      temp = temp & "</table>"
      DisplayRecords = temp       
    Else
