一个将数据库里面的内容生成EXCEL的例子


March 25,2004
1、ASP文件:

<%@ LANGUAGE="VBSCRIPT" %>
<%option explicit%>
<%
'EXAMPLE AS:把数据库中一个每天24小时在线人数放到一个EXCEL文件中去
'AUTHOR    :钢铁工人
'EMAIL     :hello_hhb@21cn.com
'DATE      :2001-3-25
'TEST      :在NT4,SP6,SQL SERVER 7.0,EXCEL2000中测试通过
%>
<HTML>
<HEAD>
<meta content="text/html; charset=gb2312" http-equiv="Content-Type">
<TITLE>生成EXCEL文件</TITLE>
</HEAD>
<body>
<a href="dbtoexcel.asp?act=make">生成在线人口的EXCEL</a>
<hr size=1 align=left width=300px>
<%
if Request("act") = "" then
else

  dim conn
  set conn=server.CreateObject("adodb.connection")
  conn.Open "test","sa",""
  'conn.Open Application("connstr")

  dim rs,sql,filename,fs,myfile,x,link
  
  Set fs = server.CreateObject("scripting.filesystemobject")
  '--假设你想让生成的EXCEL文件做如下的存放
  filename = "c:online.xls"
  '--如果原来的EXCEL文件存在的话删除它
  if fs.FileExists(filename) then
    fs.DeleteFile(filename)
  end if
  '--创建EXCEL文件
  set myfile = fs.CreateTextFile(filename,true)


  
  Set rs = Server.CreateObject("ADODB.Recordset")
  '--从数据库中把你想放到EXCEL中的数据查出来
  sql = "select population,hourpos,datepos from populationperhour order by datepos,hourpos asc"
  rs.Open sql,conn
  if rs.EOF and rs.BOF then
  
  else
  
    dim strLine,responsestr
    strLine=""
      For each x in rs.fields
        strLine= strLine & x.name & chr(9)
      Next
   
      '--将表的列名先写入EXCEL
      myfile.writeline strLine

      Do while Not rs.EOF
      strLine=""
     
      for each x in rs.Fields
        strLine= strLine & x.value & chr(9)
      next
      '--将表的数据写入EXCEL
      myfile.writeline strLine

      rs.MoveNext
      loop
      
  end if

rs.Close
set rs = nothing
conn.close
set conn = nothing
set myfile = nothing
Set fs=Nothing

link="<A HREF=" & filename & ">Open The Excel File</a>"
Response.write link
end if
