asp操作数据库以及文本文件

asp操作sql

显示表的内容
<%
set conn=Server.Createobject("adodb.connection") 
connstr="driver={SQL Server};server=WIN-I1F2TODGAHT;uid=wg365;pwd=mark168@;database=WebBuy" 
on error resume next
conn.open connstr 
response.write conn.state 
if err then 
response.write "错误！"
else
response.write "成功！"
sql = "select * from Admin"  
set rs= Server.CreateObject("ADODB.RecordSet")  
rs.Open sql,conn,1,1  
'获得连接信息与查询结果行数  
Response.write("连接1："&conn.ConnectionString&"
 spt_values行数："&rs.recordcount&"

")  
'循环结果输出  
do While not rs.eof  
    Response.write(rs(0)&","&rs(1)&","&rs(2)&","&rs(3)&","&rs(4)&"
")  
    rs.MoveNext  
Loop  
rs.close()  
conn.close()  
end if 
err.clear  
%>



插入数据到表
alert是提示框，confirm是询问框
<%
set conn=Server.Createobject("adodb.connection") 
connstr="driver={SQL Server};server=WIN-I1F2TODGAHT;uid=wg365;pwd=mark168@;database=WebBuy" 
on error resume next
conn.open connstr 
if err then 
response.write "错误！"
else
m=request("m")
sql="INSERT INTO Admin (Accounts,Pwd) VALUES ('Wilson','"&m&"')"
set rs= Server.CreateObject("ADODB.RecordSet")  
rs.Open sql,conn,1,1  
rs.close()  
conn.close()  

Response.Write("")
Response.Write("")       
end if  
err.clear  
%>

 DELETE FROM 表名 WHERE 条件
update good set gicd=6 where gicd=4

asp操作txt

读取txt
<%
dim fso,f
    set fso=server.CreateObject("Scripting.FileSystemObject")
    Set f =  fso.OpenTextFile(Server.MapPath("1.txt"),1) 
    Do  While  Not  f.AtEndOfStream   
    response.write f.readline
    loop
    f.close
    set f=nothing
    set fso=nothing
%>


line=txt.ReadAll'读取文件中的所有数据 
line=txt.ReadLine'从文件中读取一行数据
line=txt.Read(N)'从文件中读取N个字节的数据
txt.SkipLine跳过一行


写入txt
<%

testfile=server.mappath("1.txt")

msg=request("df")

set fs=server.createobject("scripting.filesystemobject")

set thisfile=fs.opentextfile(testfile,8,true,0)

thisfile.writeline("message="+df) 

thisfile=close

set fs=nothing

%>



<%
dim fso,f
    set fso=server.CreateObject("Scripting.FileSystemObject")
    Set f =  fso.OpenTextFile(Server.MapPath("1.txt"),1) 
    f.SkipLine
    one=f.readline
    response.write one   
    f.close
    set f=nothing
    set fso=nothing
%>
