sqlserver数据库获取数据库信息

ms sql server 获取当前数据库文件等信息,适用于多个版本:

复制代码 代码如下:

select dbf.file_id as fileid

    , dbf.name as [filename]

    , s.filename as filelocation

    , cast(dbf.size/128.0 as decimal(19,2)) as filesizemb

    , cast(cast(fileproperty(dbf.name, ‘spaceused’) as int)/128.0 as decimal(19,2)) as spaceusedmb

    , cast(dbf.size/128.0 – cast(fileproperty(dbf.name, ‘spaceused’) as int)/128.0 as decimal(19,2)) as availablespacemb

    , cast((dbf.size / 128.0 – (fileproperty(dbf.name, ‘spaceused’) / 128.0)) / (dbf.size / 128.0) * 100 as decimal(19,2)) as [%freespace]

    , dbf.growth / 128 as filegrowthmb

    , f.name as filegroupname

from sys.database_files dbf

    inner join sys.sysfiles s on dbf.name = s.name

    left join sys.filegroups f on dbf.data_space_id = f.data_space_id

order by dbf.name;

例如我们在某个database上,执行结果是:

复制代码 代码如下:

xxx_standard_data   

d:\program files\sqlserver2012\mssql11.mssqlserver\mssql\data\wolf_wanzheng.mdf    2000.00    1286.38    713.63    35.68    0    primary

xxx_standard_log   

d:\program files\sqlserver2012\mssql11.mssqlserver\mssql\data\wolf_wanzheng_2.ldf    157.19    2.47    154.72    98.43    0    null

xxx_temp2_data

 xxx_temp2_log
