• 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
