Question

Something like:

create table Employee(
ID int primary key,
Name nvarchar(200)
IDArea int foreign key references Area(ID)
);

go

create table Area(
ID int primary key,
Name nvarchar(200)
);

Does something like this exist in Oracle?

Answer 1

Yes, just leave out the “GO” keywords and put the statements in a file:

create table Area(
ID int primary key,
Name nvarchar2(200)
);

create table Employee(
ID int primary key,
Name nvarchar2(200),
IDArea int references Area(ID)
);

You must create the Area primary key before the foreign key that references it, so I have swapped these around. Also the foreign key syntax is slightly different in Oracle.
