利用ASP制作EXECL报表方法(一)
作者:采集员 文章来源:来源于网络 点击数: 更新时间:2005/9/10 13:35:46
很多时候我们需要把表格形式的数据转换成EXECL的形式呈现在用户面前,其中有好几个方法可以做到一点,我将介绍一种利用ASP完成的方法,该方法允许服务器动态地创建EXECL报表而且不用占用任何服务器空间。该方法还允许多个用户同时收到该数据。但是该方法至少需要EXECL 97的支持。
   废话少说,要完成这个工作最重要的是要告诉浏览器HTTP头,就用如下代码:

   <%
       Response.ContentType = "application/vnd.ms-excel"
   %>

   下面来看一个例子,假设现在有如下形式的数据:
   flavor      qty_baked      qty_eaten     qty_sold     price
   Boston      24             2             10           0.5
   Jelly       24             1             12           0.5
   Strawberry  36             1             15           0.5
   Chocolate   24             2             6            0.75
   Maple       12             1             6            0.75

   客户要求用EXECL的形式表现出来,并且希望其中能加上其他一些计算汇总

   用如下代码:
   ……
  <%
   Response.ContentType = "application/vnd.ms-excel"

   set conntemp=server.createobject("adodb.connection")
    cnpath="DBQ=" & server.mappath("/stevesmith/data/timesheet.mdb")
    conntemp.Open "DRIVER={Microsoft Access Driver (*.mdb)}; " & cnpath
    set RS=conntemp.execute("select * from donut")
    %>
     <TABLE BORDER=1>
    <TR>
    <%
   ' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   ' % Loop through Fields Names and print out the Field Names
   ' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    j = 2 'row counter
    For i = 0 to RS.Fields.Count - 1
    %>
    <TD><B><% = RS(i).Name %></B></TD>
    <% Next %>
    <TD><B>On Hand (calculated)</B></TD>
    <TD><B>Gross (calculated)</B></TD>
    </TR>
    <%
   ' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   ' % Loop through rows, displaying each field
   ' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    Do While Not RS.EOF
    %>
    <TR>
    <% For i = 0 to RS.Fields.Count - 1
    %>
    <TD VALIGN=TOP><% = RS(i) %></TD>
    <% Next %>
    <TD>=b<%=j%>-c<%=j%>-d<%=j%></TD>
    <TD>=d<%=j%>*e<%=j%></TD>
    </TR>
    <%
    RS.MoveNext
    j = j + 1
    Loop
   ' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   ' % Make sure to close the Result Set and the Connection object
   ' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    RS.Close
    %>
    <TR BGCOLOR=RED>
    <TD>Totals</TD>
    <TD>=SUM(B2:B6)</TD>
    <TD>=SUM(C2:C6)</TD>
    <TD>=SUM(D2:D6)</TD>
    <TD>n/a</TD>
    <TD>=SUM(F2:F6)</TD>
    <TD>=SUM(G2:G6)</TD>
    </TABLE>
   ……
  这样我们就实现了目的,用户可以在浏览器窗口就打开它进行简单操作,也可以保存到硬盘上进行其他操作。我还将介绍一种利用filesystemobject操作的方法。请稍候。:)
