Hi
dedicated SQL pool does not use Partitioning functions and schemes as they are used in SQL Server. The partitioning is configured in the table configuration (CREATE/ ALTER). This make the question more interesting since we cannot based on the Partitioning functions for the filtering in the SELECT query.
With that being said, you still have (or can find) the configuration of the table DDL and using the CREATE TABLE statement you know what is the partitioning rule.
Next you simply write a query which uses the same filter using WHERE condition
