Note that referencing other tables in the filter expression by use of a subselect could have performance implications in some data sources. However, the designer can totally control the SQL expression by defining a named query in the data source view, and then referencing that.

The method of defining the bindings for a partition are independent of the use of partitioned tables in the data source view.

As an example, consider a measure group whose default table is "Sales," with columns Date, Product ID, Qty, Price, and Amount (calculated in the data source view). Then the partition "Sales97" could use the table "Sales97" with filter "Year(Sales.Date) = 97."

The effective query is:

   SELECT Date, Product ID, Qty, Price, Qty * Price AS Amount 
      FROM Sales97 As Sales
      WHERE Year(Sales.Date) = 97

The calculated expression still applies, even if the expression used qualified table names (for example, Sales.Qty). The same applies if instead the table were replaced by some query "SELECT…" The FROM clause above would become "FROM SELECT ... As Sales."
