asp教程 删除数据库教程记录其实在asp中是很非常容易做的事情了,只要连接数据库了,再利用sql delete函数来删除就ok了,下面来看看实例吧。

id = saferequest("id")
sql="delete from table1 where whereid>"&id&""
rs.open sql,conn,1,3
response.write "<script>alert('删除成功');location.href='del.asp';</script>"
set rs=nothing
set conn=nothing

这是过滤非法字符函数

function saferequest(paraname)
dim paravalue
paravalue=request(paraname)
if isnumeric(paravalue) = true then
saferequest=paravalue
exit function
elseif instr(lcase(paravalue),"select ") > 0 or instr(lcase(paravalue),"insert ") > 0 or instr(lcase(paravalue),"delete from") > 0 or instr(lcase(paravalue),"count(") > 0 or instr(lcase(paravalue),"drop table") > 0 or instr(lcase(paravalue),"update ") > 0 or instr(lcase(paravalue),"truncate ") > 0 or instr(lcase(paravalue),"asc(") > 0 or instr(lcase(paravalue),"mid(") > 0 or instr(lcase(paravalue),"char(") > 0 or instr(lcase(paravalue),"xp_cmdshell") > 0 or instr(lcase(paravalue),"exec master") > 0 or instr(lcase(paravalue),"net localgroup administrators") > 0 or instr(lcase(paravalue)," and ") > 0 or instr(lcase(paravalue),"net user") > 0 or instr(lcase(paravalue)," or ") > 0 or instr(lcase(paravalue),"""")>0 or instr(lcase(paravalue),"'")>0 then
response.write "请不要在函数中加入非法字符!"
response.end
else
saferequest=paravalue
end if
end function
