برای بدست آوردن مسیر ذخیره سازی فایلهای پایگاه داده SQL Server میتوانید از Query زیر اسفتاده کنید:
کد:
USE master
GO
SET NOCOUNT ON
DECLARE @Kb float
DECLARE @PageSize float
DECLARE @SQL varchar(max)
SELECT @Kb = 1024.0
SELECT @PageSize=v.low/@Kb FROM master..spt_values v WHERE v.number=1 AND v.type='E'
IF OBJECT_ID('tempdb.dbo.#FileSize') IS NOT NULL DROP TABLE #FileSize CREATE TABLE #FileSize ( DatabaseName sysname, [FileName] varchar(max), FileSize int, FileGroupName varchar(max), LogicalName varchar(max)
)
IF OBJECT_ID('tempdb.dbo.#FileStats') IS NOT NULL DROP TABLE #FileStats CREATE TABLE #FileStats ( FileID int, FileGroup int, TotalExtents int, UsedExtents int, LogicalName varchar(max), FileName varchar(max)
)
IF OBJECT_ID('tempdb.dbo.#LogSpace') IS NOT NULL DROP TABLE #LogSpace CREATE TABLE #LogSpace ( DatabaseName sysname, LogSize float, SpaceUsedPercent float, Status bit
)
INSERT #LogSpace EXEC ('DBCC sqlperf(logspace)')
DECLARE @DatabaseName sysname
DECLARE cur_Databases CURSOR FAST_FORWARD FOR SELECT DatabaseName = [name] FROM dbo.sysdatabases WHERE [name] <> 'RVR_FSA' ORDER BY DatabaseName OPEN cur_Databases FETCH NEXT FROM cur_Databases INTO @DatabaseName WHILE @@FETCH_STATUS = 0
BEGIN
print @DatabaseName
SET @SQL = '
USE [' + @DatabaseName + '];
DBCC showfilestats;
INSERT #FileSize (DatabaseName, [FileName], FileSize, FileGroupName, LogicalName) SELECT ''' +@DatabaseName + ''', filename, size, ISNULL(FILEGROUP_NAME(groupid),''LOG''), [name] FROM dbo.sysfiles sf; '
PRINT @SQL
INSERT #FileStats EXECUTE (@SQL)
FETCH NEXT FROM cur_Databases INTO @DatabaseName
END
CLOSE cur_Databases
DEALLOCATE cur_Databases
SELECT
DatabaseName = fsi.DatabaseName,
FileGroupName = fsi.FileGroupName,
LogicalName = RTRIM(fsi.LogicalName),
[FileName] = RTRIM(fsi.FileName),
