MRvl> Dear Marco Cantú and Dmitry Yemanov,
MRvl> I wonder, if and when deferred constraint will be implemented?
MRvl> As far as I understand, developer should have the possibility of raising
MRvl> exception errors right when it happens or later, after filling the full
MRvl> screen data information, when commiting the insert/update transaction.
MRvl> For not stopping in all the time the program/user passe's on each field,
MRvl> like it happens in postgresql. When developers or analysts have to make
MRvl> decisions, constraints may be deferred for a  later time.
MRvl> When committing the application raises the all list of deferred
MRvl> constraints, this is very important to do in the server and it is not easy
MRvl> to implement in your exe, because firebird Stop's the application  at the
MRvl> backend.
MRvl> Best regards


MRvl> Com os meus melhores cumprimentos
