SQLServer查看分區表詳細信息

SQL查看分區內記錄個數，常規方法需要知道分區函數然后再顯示，網上看到一個一句話顯示的方法

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')--分區表名
and i.index_id in (0, 1)
order by p.partition_number

執行效果如下

 其它方法

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

查看分區記錄數

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

查看記錄所在分區

 

dbcc shrinkfile(N'yxfile001',1)

收縮分區文件yxfile001為1M

 

 

select * from sysfiles

查詢數據庫文件以及日志文件的相關信息（文件組、當前文件大小、文件最大值、文件增長設置、文件邏輯名、文件路徑）

 

 

exec master.dbo.xp_fixeddrives

查詢各個磁盤分區的剩余空間

 

 

exec sp_spaceused

查詢當前數據庫的磁盤使用情況

 

 

select * from sys.partition_range_values

可以查詢到分區號
