SQL查看分区内记录个数，常规方法需要知道分区函数然后再显示，网上看到一个一句话显示的方法
select convert(varchar(50), ps.name ) as partition_scheme, p.partition_number, convert(varchar(10), ds2.name ) as filegroup, convert(varchar(19), isnull(v.value, ‘‘), 120) as range_boundary, str(p.rows, 9) as rows from sys.indexes i join sys.partition_schemes ps on i.data_space_id = ps.data_space_id join sys.destination_data_spaces dds on ps.data_space_id = dds.partition_scheme_id join sys.data_spaces ds2 on dds.data_space_id = ds2.data_space_id join sys.partitions p on dds.destination_id = p.partition_number and p.object_id = i.object_id and p.index_id = i.index_id join sys.partition_functions pf on ps.function_id = pf.function_id LEFT JOIN sys.Partition_Range_values v on pf.function_id = v.function_id and v.boundary_id = p.partition_number - pf.boundary_value_on_right WHERE i.object_id = object_id(‘yourtablename‘)--分区表名 and i.index_id in (0, 1) order by p.partition_number
