The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 7: FILESTREAM Database AdministrationTo see this working, go back to the FILESTREAM data folder and delete the file we justcreated. Run DBCC CHECKTABLE again, and you will see that the error is reported again.Run the script in Listing 7-16 to fix the corruption by deleting the records that havecorrupted FILESTREAM values. The first action the script performs is to take thedatabase into single user mode. The database needs to be in single user mode to performa repair operation.ALTER DATABASE NorthPole SET SINGLE_USERWITH ROLLBACK IMMEDIATEGODBCC CHECKDB('NorthPole', repair_allow_data_loss)/*Msg 7904, Level 16, State 2, Line 2Table error: Cannot find the FILESTREAM file "00000015-0000005e-0004"for column ID 4 (column directory ID 4d8cb114-f573-490e-adfa-e4583889b836) inobject ID 2105058535, index ID 0, partition ID 72057594038779904, page ID (1:157),slot ID 0.The error has been repaired.Msg 8945, Level 16, State 1, Line 2Table error: Object ID 2105058535, index ID 2 will be rebuilt.The error has been repaired.*/Listing 7-16:Fixing FILESTREAM corruption by deleting the affected rows.If you run a query on the Items table, you will see that it now has only one row; the rowfrom which the FILESTREAM data was missing has been deleted as part of the repairprocess. Again, keep in mind that this approach may or may not be acceptable, dependingupon the nature of your application and sensitivity of the data.290
