RE: Prototyped Procedures

What makes odbc any more vicious than UPDDTA?
At this point you have to decide on either using "Access-level" security 
which basically means they cannot access the data unless they use a 
program that adopts authority, or, use column level security.  Column 
level security was implemented on day 1 of OS/400 by only allowing access 
via logical files that contained only the fields they were allowed to see 
or update.  Much more recent versions of OS/400 allow you to define it on 
the physical file itself.  The problem is that many programmers would be 
loathe to change their code to something like:

dow 1=1;
  if F3;
    Leave;
  EndIf;
  // decide which fields the user actually changed.  Customize the update 
statement accordingly.
  ...
  update(e) myfile %fields(...);
  Select;
  When not %error;
    Leave;
  When %status = NotAuthorized;
    // Hey Bozo, you're not allowed to change the salary field!  I'm 
telling Mom!
  ...
  EndSl;
Exfmt;
EndDo;

RE: Prototyped Procedures






Yeah, I remember that all too clearly myself with BPCS, Ron.  Of course,
nowadays, people allow direct ODBC access to their database -- I can't
think of anything worse.  Even with triggers in place, there's nothing
stopping someone from changing descriptions or prices, or even
transaction dates, unless you have a WHOLE lot of code in your trigger
(and that's a different debate).
