Is primary key always clustered?

Question

Please clear my doubt about this, In SQL Server (2000 and above) is primary key automatically cluster indexed or do we have choice to have non-clustered index on primary key?

Answer 1

Nope, it can be nonclustered. However, if you don't explicitly define it as nonclustered and there is no clustered index on the table, it'll be created as clustered.
