asp中把数据导出为excel的2种方法
我们在做项目的时候经常要将数据库的数据导出到excel中，很多asp用户并不知道怎么写。
这里明凯总结了两种方法来导出excel，希望能帮到大家。
方法一：用excel组件
< %
set rs=server.createobject("adodb.recordset")
sql="select * from mkusers"
rs.open sql,objconn,1,1
Set ExcelApp =CreateObject("Excel.Application")
ExcelApp.Application.Visible = True
Set ExcelBook = ExcelApp.Workbooks.Add
ExcelBook.WorkSheets(1).cells(1,1).value ="用户表"
ExcelBook.WorkSheets(1).cells(2,1).value = "用户编号"
ExcelBook.WorkSheets(1).cells(2,2).value = "登陆名"
ExcelBook.WorkSheets(1).cells(2,3).value = "真实姓名"
ExcelBook.WorkSheets(1).cells(2,4).value = "密码"
cnt =3
do while not rs.eof
ExcelBook.WorkSheets(1).cells(cnt,1).value = rs("provinceid")
ExcelBook.WorkSheets(1).cells(cnt,2).value = rs("province")
ExcelBook.WorkSheets(1).cells(cnt,3).value = rs("flag")
ExcelBook.WorkSheets(1).cells(cnt,4).value = rs("id")
rs.movenext
cnt = cint(cnt) + 1
loop
Excelbook.SaveAs "d:\yourfile.xls" '这个是数据导出完毕以后在D盘存成文件
ExcelApp.Application.Quit '导出以后退出Excel
Set ExcelApp = Nothing '注销Excel对象
%>< %
set rs=server.createobject("adodb.recordset")
sql="select * from mkusers"
rs.open sql,objconn,1,1
Set ExcelApp =CreateObject("Excel.Application")
ExcelApp.Application.Visible = True
Set ExcelBook = ExcelApp.Workbooks.Add
ExcelBook.WorkSheets(1).cells(1,1).value ="用户表"
ExcelBook.WorkSheets(1).cells(2,1).value = "用户编号"
ExcelBook.WorkSheets(1).cells(2,2).value = "登陆名"
ExcelBook.WorkSheets(1).cells(2,3).value = "真实姓名"
ExcelBook.WorkSheets(1).cells(2,4).value = "密码"
cnt =3
do while not rs.eof
ExcelBook.WorkSheets(1).cells(cnt,1).value = rs("provinceid")
ExcelBook.WorkSheets(1).cells(cnt,2).value = rs("province")
ExcelBook.WorkSheets(1).cells(cnt,3).value = rs("flag")
ExcelBook.WorkSheets(1).cells(cnt,4).value = rs("id")
rs.movenext
cnt = cint(cnt) + 1
loop
Excelbook.SaveAs "d:\yourfile.xls" '这个是数据导出完毕以后在D盘存成文件
ExcelApp.Application.Quit '导出以后退出Excel
Set ExcelApp = Nothing '注销Excel对象
%>
方法二：使用文件组件
< %
dim s,sql,filename,fs,myfile,x
Set fs = server.CreateObject("scripting.filesystemobject")
'--假设你想让生成的EXCEL文件做如下的存放
filename = Server.MapPath("order.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)
StartTime = Request("StartTime")
EndTime = Request("EndTime")
StartEndTime = "AddTime between #"& StartTime &" 00:00:00# and #"& EndTime &" 23:59:59#"
strSql = "select * from mksuers "
Set rstData =conn.execute(strSql)
if not rstData.EOF and not rstData.BOF then
dim trLine,responsestr
strLine=""
For each x in rstData.fields
strLine = strLine & x.name & chr(9)
Next
'--将表的列名先写入EXCEL
myfile.writeline strLine
Do while Not rstData.EOF
strLine=""
for each x in rstData.Fields
strLine = strLine & x.value & chr(9)
next
myfile.writeline strLine
rstData.MoveNext
loop
end if
Response.Write "生成EXCEL文件成功，点击<a href="/" rel="external nofollow" order.xls"" target=""_blank"">下载！"
rstData.Close
set rstData = nothing
Conn.Close
Set Conn = nothing
%>
可以看出，第一种方法是直接导出的是excel文件，而第二张方法是到处的是文本文件，只不过后缀名改成了xls。
然后看起来就是excel了。
经过对比第一种方法的效率没有第二种方法的效率高，而且也不好控制。
推荐大家使用第二种写文件的方法来进行excel操作。
