Don't take life so seriously, you will never get out of it alive.

Code for preventing SQL Injection
array_split_item = Array(”–”, “;”, “/*”, “*/”, “@@”, “@”,
“char”, “nchar”, “varchar”, “nvarchar”,
“alter”, “begin”, “cast”, “create”, “cursor”,
“declare”, “delete”, “drop”, “end”, “exec”,
“execute”, “fetch”, “insert”, “kill”, “open”,
“select”, “sys”, “sysobjects”, “syscolumns”,
“table”, “update”, “<script”, “</script>”, “‘”)
for each item in Request.QueryString
for array_counter = lbound(array_split_item) to ubound(array_split_item)
item_postion1 = InStr(lcase(Request(item)),array_split_item(array_counter))
‘Response.Write(array_split_item(array_counter) & “<br>”)
if item_postion1 > 0 then
Response.Write(”Command cannot be executed.”)
Response.End()
end if
next
