Installing the pubs2 and pubs3 sample databases is optional. These databases are provided as a learning tool for Adaptive Server. The pubs2 sample database is used for most of the examples in the Adaptive Server documentation, except for examples, where noted, that use the pubs3 database. For information about installing pubs2 and pubs3, see the installation documentation for your platform. For information about the contents of these sample databases, see the Transact-SQL User’s Guide.
