Subject Rollback event on trigger
Author Adomas Urbanavicius
Is it possiple somehow to rollback edit/delete/insert event on trigger
automatically ?
I can raise ecxeption, but what if I want to do it silently.
Something like
table tb_cutomers

trigger on delete
..... test if customer has some not returned loans ..... then
else delete it.

It is possible to do so in App, but some "clever" customers admins can
access raw table via console and write "delete from tb_customers...." :))
Same with edition or insertion.
