Set a role in a form?

----- see an old responce; start nagging for a feature called sysdbopen in IDS; the way it exist in V8 ifx xps. OR: an ugly hack may be creating a select trigger on the table(s) in the form which executes a spl which sets the role; (V9 dbengine only!!) users must then first select something... and users must have select priv on the table; the role can then set the appropiate upd/del/ins permissions?? Superboer. sysdbopen is the way to go though.
