asp完成数据记录地备份及恢复

保存数据记录到文件中：
set fs=server.CreateObject("Scripting.FileSystemObject")
FilePath=server.MapPath("backup.txt")
OldFilePath=server.MapPath("oldbackup.txt")
fs.DeleteFile OldFilePath,true
fs.MoveFile FilePath,OldFilePath
set f=fs.OpenTextFile(FilePath,8,true)
f.writeline rs.RecordCount
f.writeline rs.Fields.count
for i=1 to rs.RecordCount
'f.writeline i
for j=0 to rs.Fields.count-1
tt=rs.Fields(j)
if Len(rs.Fields(j)) then '对非空记录
tt=cstr(tt)
tt=replace(tt,chr(13)&chr(10),chr(35)&chr(35)) '替换记录中的换行符
end if
f.writeline rs.fields(j).name&"="&tt
next
rs.movenext
next

以下是恢复数据记录到库中：
其中用到的函数：
function rsname(str) '取字段名称
str=cstr(str)
tt=instr(1,str,"=")
rsname=left(str,tt-1)
end function
function rsvalue(str) '取字段值
str=cstr(str)
tt=instr(1,str,"=")
rsvalue=replace(mid(str,tt+1),chr(35)&chr(35),chr(13)&chr(10)) '恢复回车符
end function
function DelPoint(sql) '去掉sql中最后一个","
l=len(sql)
l=l-1
sql=Left(sql,l)
delpoint=sql
end function
<%
sum=f.readline
sum=cint(sum) '总记录数
fields=f.readline
fields=cint(fields)'列数
dim str()

for n=1 to sum
for m=0 to fields-1
redim preserve str(m)
str(m)=f.readline
next
sql1="insert into gajjsj ("
sql2=" values ("
for m=0 to fields-1
sql1=sql1&rsname(str(m))&","
sql2=sql2&rsvalue(str(m))&","
next
sql1=Delpoint(sql1)&") "
sql2=Delpoint(sql2)&")"
sql=sql1&sql2
Response.Write "第"&n&"条记录:"&"<br>sql:"&sql&"<br><br>"
conn.Execute (sql) '自定义函数执行sql
redim str(1)
next
%>
