The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 3: Accessing FILESTREAM Data from Client ApplicationsThe example above shows the logical path to the FILESTREAM data inserted into theItems table using the script in Listing 3-27 on the author's computer. If you run the codeon your computer, you might see a slightly different result.Table 3-1 dissects the various different component parts of the logical path name of aFILESTREAM data file.\\localhost\MSSQLSERVERComputer name.FILESTREAM share name.FILESTREAM version number (used internally).\v1\NorthPole\dbo\Items\\ItemImage\E76D878F-0B2D-48EE-906E-58349797D6ECOn SQL Server 2008 and 2008 R2 the versionnumber shows up as "v1." On SQL Server2012, the version number shows up as "v02"which is part of a more complex value such as"v02-A60EC2F8-2B24-11DF-9CC3-AF2E56D89593."Fully qualified object name (Database\Schema\Table).Column name.File identifier. This is the value of the ROWGUIDCOLof the current row.VolumeHint-HarddiskVolume2 This additional value is seen only in SQL Server 2012.Table 3-1:The components of the logical path name.Note that the logical path name is useful only to SQL Server; you cannot reliably identifythe disk file using this information. SQL Server installs a filter driver which translates thelogical path name to the correct disk file when you try to access it using the streamingAPI functions.118
