[gnome-db] trigger

[Andrea Zagli <azagli libero it>]

i would like to realize on my applications, based on libgda, something  
similar to trigger

is there some function/signal to make it possible? for example 2  
signals named "before-non-select-execution" and  
"after-non-select-execution" on GdaConnection

i don't want to use dbms triggers, because i want that my applications  
are really multi-dabatase

thanks in advance
