I have created a foreign key (in mssql / tsql) by:
alter table company add CountryID varchar(3);
alter table company add constraint Company_CountryID_FK foreign key(CountryID)
references Country;
I then run this query:
alter table company drop column CountryID;
and I get this error:
Msg 5074, Level 16, State 4, Line 2
The object 'Company_CountryID_FK' is dependent on column 'CountryID'.
Msg 4922, Level 16, State 9, Line 2
ALTER TABLE DROP COLUMN CountryID failed because one or more objects access this column.
alter table company drop foreign key Company_CountryID_FK;
alter table company drop column CountryID;
What do I need to do to drop the CountryID column?
Thanks.
