Change non-primary key field to become a primary key

134 Views

Hi guys,

I need to change a a non-PK field to become a PK.

But I'm afraid it might delete the existing data entries.

Can you teach me the steps on how to make that field primary and at the same time the entries won't be deleted?

Thanks.

I searched for one, but the answers are not organized.
