Re: Dropping Foreign Key without recreating table

Oops disregard my prev reply,

"RI_ConstraintTrigger_17195" is a trigger not contraint so u must in 7.2.1 do
DROP TRIGGER "RI_ConstraintTrigger_17195" on mytable ;

in 7.3  foreign key constraints on tables have name.
so you need not drop underlying triggers like in 721 but can use command to
drop the contraint which u are attempting now like
alter table  mytable drop constraint "NAME OF THE FKEY CONSTRAINT" restrict ;

cheers
