Chapter 7: FILESTREAM Database AdministrationMigrating FILESTREAM DataThe recommended way to move or copy large databases from one location to anotheris to restore a full backup (see Chapter 8). However, in cases where restoring backups isnot allowed, such as in a shared hosting location, or when only selected objects need tobe restored, we can resort to scripting of the schema and data to transport SQL Serverobjects from one location to another. It is possible to script tables with FILESTREAMdata but it is only recommended in cases where the database size is relatively small, andscripting data of FILESTREAM-enabled databases is recommended only if the BLOBvalues are small.SSMS scriptingThe scripting functionality offered by SSMS allows us to create INSERT scripts that canbe executed on another location to re-create the FILESTREAM data. You can do thisby setting the export option Type of data to script to Schema and data or Data only, asshown in Figure 7-2.Figure 7-2:Selecting the types of data to script.306
Chapter 7: FILESTREAM Database AdministrationThe scripting process does not require any FILESTREAM-specific changes; it is the sameas the process for a non-FILESTREAM database. SSMS generates INSERT statementsto populate the target database with the same values as the source table, including theFILESTREAM columns. FILESTREAM columns are exported as a hex string, as shown inListing 7-37.INSERT [dbo].[Items] ([ItemID],[ItemNumber],[ItemDescription],[ItemImage])VALUES (N'f326ed65-5131-4ef7-891a-89fad516b856',N'MS1001', N'Microsoft Mouse',0xFFD8FFE000104A46494600010100000100010000FFDB004300090607080706090807080A0A090B0D160F0D0C0C0D1B14151016201D2222201D1F1F2428342C242631271F1F2D3D2D335373A3A3A232B3F443F384334393A37FFDB0043010A0A0A0.................................................3737373737373737373737FFC00011080067007A030122000)Listing 7-37:INSERT statement for a FILESTREAM column.The Scripting Wizard allows us to generate scripts to be deployed on a different versionof SQL Server. This is one of the areas where the scripting functionality adds value overregular backups, as we cannot, for example, restore a SQL Server 2008 R2 backup onSQL Server 2008.We select the target database in the Advanced Scripting Options screen (Figure 7-3).307
