Pessoal,
Encontrei esse link no “tuite” de alguém, mas não lembro a fonte.
De qualquer maneira, deixo registrado aqui o link para BOL do SQL Server 2012 offline.
“The Microsoft SQL Server 2012 setup installs only the Help Viewer and related components for managing Help settings. Setup does not directly install any documentation. All of the SQL Server documentation is available online. For more information on installing SQL Server product documentation behind a firewall, see the Overview and Instructions sections below.”
Abraço, Rodrigo.
