I have a simple question about SQL Server. When I define a field on a table as the primary key, does SQL Server automatically create a corresponding index on that field or do I need to create the index myself.

Thanks

By default SQL Server creates a clustered index on the primary key.

Anyone know what query I could use to set a primary key using a syntax on a table?

Look in the SQL Books Online under "Alter Table"
