SQLServer查看分区表详细信息

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

执行效果如下

其它方法

select count(1) ,$PARTITION.WorkDatePFN(workdate) from imgfile group by $PARTITION.WorkDatePFN(workdate)

查看分区记录数

select workdate ,$PARTITION.WorkDatePFN(workdate) from imgfile

查看记录所在分区

 

dbcc shrinkfile(N'yxfile001',1)

收缩分区文件yxfile001为1M

 

 

select * from sysfiles

查询数据库文件以及日志文件的相关信息（文件组、当前文件大小、文件最大值、文件增长设置、文件逻辑名、文件路径）

 

 

exec master.dbo.xp_fixeddrives

查询各个磁盘分区的剩余空间

 

 

exec sp_spaceused

查询当前数据库的磁盘使用情况

 

 

select * from sys.partition_range_values

可以查询到分区号
