简单导出到excel二则
1.利用IE和html的ContentType。
最简单且可导出6W以内记录。
06 |
html= "<table><tr><td>105</td><td>105223</td><td>中国</td><td>北京</td><td>广州</td><td>4.5</td><td>0</td><td>茂名</td><td>树仔</td><td>内园</td><td>电白 </td></tr><tr><td>105</td><td>105223</td><td>中国</td><td>北京</td><td>广州</td><td>4.5</td><td>0</td><td>茂名</td><td>树仔</td><td>内园</td><td>电白 </td></tr><tr><td>105</td><td>105223</td><td>中国</td><td>北京</td><td>广州</td><td>4.5</td><td>0</td><td>茂名</td><td>树仔</td><td>内园</td><td>电白 </td></tr><tr><td>105</td><td>105223</td><td>中国</td><td>北京</td><td>广州</td><td>4.5</td><td>0</td><td>茂名</td><td>树仔</td><td>内园</td><td>电白 </td></tr></table>" |
09 |
<form action= "export.asp" method= "post" > |
10 |
<input type= "hidden" name= "export" value= "<%=html%>" > |
11 |
<input type= "button" name= "submit" value= "导出当前页面表数据" > |
06 |
Response.ContentType= "application/vnd.ms-excel" |
07 |
Response.AddHeader "content-disposition" , "attachment;filename=Test.xls" |
08 |
Response.Buffer = True |
09 |
Response.ExpiresAbsolute = Now() - 1 |
11 |
Response.CacheControl = "no-cache" |
12 |
Response.AddHeader "Pragma" , "No-Cache" |
15 |
response.Write "<table>" |
17 |
response.Write "<tr><td>105</td><td>105223</td><td>中国</td><td>北京</td><td>广州</td><td>4.5</td><td>0</td><td>茂名</td><td>树仔</td><td>内园</td><td>电白 </td></tr>" |
19 |
if i=65000 then response.end |
21 |
response.Write "</table>" |
2.利用模版生成excel文件
主目录下有download文件夹,download文件夹有temp.xls模版文件和temp文件夹(临时存放文件)。
需设置服务器端对temp文件夹设置可写权限。
先建立所需模版,利用查询出来的结果集再插入excel表中
4 |
<meta http-equiv=Content-Type content=”text/html; charset=GB2312″> |
6 |
Response.Charset= “GB2312″ |
7 |
Response.ContentType=”application/vnd.ms-excel” |
8 |
response.write request(“export”) |
002 |
‘模版字段 zd1,zd2,zd3….zdn(估计查询结果字段最多数量) |
004 |
‘固定格式,下面的中文标题转换就不需要做了,中文标题作为excel表temp表的字段 |
006 |
Sql = “select * From books” |
007 |
Set Rs = Db.CreateRS() |
008 |
Rs.Open Sql, Db.Conn, 1, 1 |
009 |
Dim i,TabTitle,zdstr ‘i,表头,输出字段 |
010 |
if rs.eof and rs.bof then |
011 |
response.Write “没有数据…” |
014 |
for i=0 to rs.fields.count-1 |
015 |
ReDim Preserve fileds_Array(i) |
016 |
TabTitle=TabTitle&”‘”&ChangeToCn(rs.fields(i).name)&”‘,” ‘交换成中文字段,输出标题 |
017 |
zdstr=zdstr&”zd”&cstr(i)&”,” |
018 |
fileds_Array(i)=rs.fields(i).name |
022 |
zdstr=left(zdstr,len(zdstr)-1) ‘去掉末尾“,” |
023 |
TabTitle=left(TabTitle,len(TabTitle)-1) ‘去掉末尾“,” |
024 |
‘———————————-删除之前生成的文件—————- |
025 |
dim d1,d2,fso,path,temp |
026 |
set fso = createobject(“scripting.filesystemobject”) |
027 |
path = server.mappath(“download/temp/”) |
028 |
Set temp = fso.getfolder(path) |
029 |

030 |
