我是靠谱客的博主活泼鸡翅，最近开发中收集的这篇文章主要介绍asp 删除数据库记录的代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

删除单条记录

复制代码代码如下:

 
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

复制代码代码如下:

 
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 

批量删除方法：
主要是利用for循环来实现。

复制代码代码如下:

 
id=request.form("checkbox") 
id=Split(id,",") 
shu=0 
for i=0 to UBound(id) 
sql="select * from jiang_fname where id="&id(i) 
set rs=conn.execute(sql) 
shu=shu+1 
next
