Question

I want to create a DB , where each table’s PK will be GUID and which will be unique across the DB,

Example: my DB name is ‘LOCATION’. And I have 3 table as ‘CITY’ , ‘STATE’ and ‘COUNTRY’.

I want that all the 3 tables have same PK field as GUID ,and that value will be unique across DB.

How to do this in SQL Server, any idea? I have never used SQL Server before, so it will be helpful if briefly explained.

Answer 1

create table CITY (
    ID uniqueidentifier not null primary key default newid(),
    .
    .
    .
)

Repeat for the other tables.
