Hi DB Experts,
Is always setting identity field as Primary key Sql Server Database table design is right?
My current database design style is I set the necessary field as primary key and make the identify field as unique and use the identity field for foreign key.
Some persons always setting identity key as primary and make the fields like email, username, group name as unique what method is right?
Please advice me.
Thanks in Advance
