The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 3: Accessing FILESTREAM Data from Client ApplicationsLet us now try to query the table and see the data we just inserted (Listing 3-28).SELECT * FROM Items/*ItemID Item# ItemDescription ItemImage------------ ------ --------------- -------------------E76D878F-0.. MS1001 Microsoft Mouse 0xFFD8FFE000104A4..*/Listing 3-28:Querying the Items table.The column ItemImage stores the FILESTREAM data we just inserted. To a T-SQLquery, the FILESTREAM column appears as a VARBINARY(MAX) column. However, thedata is stored in the FILESTREAM data container as a disk file. Every BLOB value in everyFILESTREAM column (in every non-NULL FILESTREAM field) has a disk file associatedwith it in the FILESTREAM data container.The logical path name refers to the disk file associated with each BLOB data value,and can be retrieved by using the new intrinsic function PathName(), as shown inListing 3-29. Note that PathName() is case sensitive. You will get an error if thecorrect case is not used when invoking this method.SELECTItemNumber,ItemImage.PathName() AS LogicalPathFROM Items/*Item# LogicalPath------ --------------------------------------------------MS1001 \\localhost\MSSQLSERVER\v1\
