删除单条记录- 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
复制代码
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

批量删除方法:
主要是利用for循环来实现。- 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
