How do I drop a foreign key in SQL Server?

Question

I have created a foreign key (in SQL Server) by:

alter table company add CountryID varchar(3);
alter table company add constraint Company_CountryID_FK foreig         


        

Answer 1

Are you trying to drop the FK constraint or the column itself?

To drop the constraint:

alter table company drop constraint Company_CountryID_FK

You won't be able to drop the column until you drop the constraint.
