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：
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：
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
