    Partitioning tables that do not contain the subscription column

Partitioning the Customer table in the Contact example

The Customer table can be partitioned using the rep_key value as a subscription column. A publication that includes the SalesRep and Customer tables would be as follows:

exec sp_add_remote_table 'SalesRep'
exec sp_add_remote_table 'Customer'
go
exec sp_create_publication 'SalesRepData'
go
exec sp_add_article 'SalesRepData', 'SalesRep'
exec sp_add_article SalesRepData,
         Customer, NULL,
         'rep_key'
go
