 This code retrieves a list of key data partition metadata for all tables in a database.
** NOTE:  The only data partitioning that was supported in SQL 2000 was via distributed partitioned views.  They do not have the same level of functionality so there is no equivalent code.



SELECT                                AS TableName,
p.partition_number                      AS PartitionNumber,
