sqlserver数据库获取数据库信息
人气:0这篇文章主要介绍了sqlserver数据库获取数据库文件信息,大家参考使用吧
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
