SQL Server - Show Content of a partition I did somes partitions on my sql database with the wizard of microsoft Sql Server Management Studio. But i wanted to know if it's possible to do an request for show just lines contains by one partition.

I tried this : 

select * from  MyTable where $PARTITION.LinkTest(ID) = 2;


But it's just show me the result of the partition function LinkTest not the lines contained on one filegroups or file. Someone know how I can do that?
This is a pretty basic query I use to get rows ( lines? ) per object on my partitioned schemes:

SELECT  DISTINCT ObjectName = so.name, ds.name, 
        sp.partition_number, sp.rows
FROM    sys.objects so
INNER JOIN sys.partitions sp
    ON  so.object_id = sp.object_id
INNER JOIN sys.destination_data_spaces dds
    ON  sp.partition_number = dds.destination_id
INNER JOIN sys.data_spaces ds
    ON  dds.data_space_id = ds.data_space_id
WHERE   so.is_ms_shipped = 0
    AND sp.rows &gt; 0
    AND ds.name &lt;&gt; 'PRIMARY'
ORDER BY so.name, ds.name;


You could add the name of your table and the partition you're interested in to the predicate:

    AND so.name = 'MyTable'
    AND sp.partition_number = 2


For a little more detailed information ( per index, compression stats, etc ), I use this little guy:

SELECT  DatabaseName = DB_NAME(), SchemaName = ss.name, 
        TableName = OBJECT_NAME( so.object_id ),
        IndexID = p.index_id, IndexName = CASE
            WHEN p.index_id = 0 
              THEN 'HEAP'
            ELSE i.name
        END, [Compression] = sp.data_compression_desc, PartitionNumber = p.partition_number,
        LowerBoundary = prv_left.value, UpperBoundary = prv_right.value,
        FileGroupName = CASE
            WHEN fg.name IS NULL 
              THEN ds.name
            ELSE fg.name
        END, UsedPagesInMB = CONVERT( NUMERIC( 18, 2 ), p.used_page_count * 0.0078125 ),
        DataPagesInMB = CONVERT( NUMERIC( 18, 2 ), p.in_row_data_page_count * 0.0078125 ),
        ReservedPagesInMB = CONVERT( NUMERIC( 18, 2 ), p.reserved_page_count * 0.0078125 ),
        [RowCount] = CASE
            WHEN p.index_id IN ( 0, 1 )
              THEN p.row_count
            ELSE 0
        END, [Type] = CASE
            WHEN p.index_id IN ( 0, 1 ) 
              THEN 'DATA'
            ELSE 'INDEX'
        END
