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,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 FilesSQLServer2012MSSQL11.MSSQLSERVERMSSQLDATAwolf_wanzheng.mdf 2000.00 1286.38 713.63 35.68 0 PRIMARY
XXX_standard_log
D:Program FilesSQLServer2012MSSQL11.MSSQLSERVERMSSQLDATAwolf_wanzheng_2.ldf 157.19 2.47 154.72 98.43 0 NULL
XXX_temp2_data
D:Program FilesSQLServer2012MSSQL11.MSSQLSERVERMSSQLDATAwolf_wanzheng_1.ndf 500.00 0.06 499.94 99.99 0 temp2
XXX_temp2_log
D:Program FilesSQLServer2012MSSQL11.MSSQLSERVERMSSQLDATAwolf_wanzheng_3.ldf 142.88 2.25 140.63 98.43 0 NULL
