Question

I don’t get it why is it that the relationship in my table is inverted? and how would I set the Foreign key to auto increment? so that when I insert a data in my parent table the primary key in my child table will also increment.

And Why is it in my diagram the relationship is inverted, here have a look

It is supposed to be the other way around, how would I do that?

I honestly wouldn’t bother trying to make the UI bend to your requirements. Instead, let’s learn some DDL!

CREATE TABLE dbo.People
(
  PeopleID INT IDENTITY(1,1) PRIMARY KEY,
  FirstName NVARCHAR(32)
  --, LastName, etc.
);

CREATE TABLE dbo.Address
(
  AddressID INT IDENTITY(1,1) PRIMARY KEY,
  PeopleID INT NOT NULL FOREIGN KEY 
    REFERENCES dbo.People(PeopleID),
  Address VARCHAR(255)
  --, other columns
);

Example of data population. Let’s say you want to add a new person named Bob who has two addresses.

DECLARE @PeopleID INT;

INSERT dbo.People(FirstName) SELECT N'Bob';

SELECT @PeopleID = SCOPE_IDENTITY();

INSERT dbo.Address(PeopleID, Address) SELECT @PeopleID, '255 Hemlock Lane';
INSERT dbo.Address(PeopleID, Address) SELECT @PeopleID, '345 Hutcheson Ave';
