    Partitioning tables that do not contain the subscription expression

Partitioning the Contact table in the Contact example

The Contact table must also be partitioned among the sales representatives, but contains no reference to the sales representative rep_key value. How can the Message Agent match a subscription value against rows of this table, when rep_key is not present in the table?

To solve this problem, you can use a subquery in the Contact article that evaluates to the rep_key column of the Customer table. The publication then looks like this:

CREATE PUBLICATION SalesRepData (
   TABLE SalesRep
   TABLE Customer
      SUBSCRIBE BY rep_key
   TABLE Contact
      SUBSCRIBE BY (SELECT rep_key
         FROM Customer
         WHERE Contact.cust_key = Customer.cust_key )
)

The WHERE clause in the subscription expression ensures that the subquery returns only a single value, as only one row in the Customer table has the cust_key value in the current row of the Contact table.

For an Adaptive Server Enterprise consolidated database, the solution is different. For more information, see Partitioning tables that do not contain the subscription column.
