    In general, the default database characteristics provided by Sybase Central are suitable. Note the following characteristics:

    • Collation sequence   Use the default collation.

    • Table name   Type Names.

    • Columns   Create columns in the Names table with the following attributes:

      Column Name Data Type (Size) Nulls Unique Default value
      ID integer No Yes (primary key) global autoincrement
      Name varchar(30) No No None

    • Primary key   Specify the ID column as primary key.

  4. Exit Sybase Central and verify the database file is created in the required directory.

  5. Link the initialized (empty) database file to your Visual Studio project so that the database file is deployed to the device along with the application code:

    • From the Visual Studio menu, click Project » Add Existing Item.

    • Click the arrow in the Add button and click Add As Link.

    • In the Solution Explorer frame, right click the database file name that has just been added to the project and click Properties.

      In the properties panel, set the Build Action property to Content; set the Copy to Output Directory property to Copy always.
