Chapter 11: FileTableperformance while these tasks are being completed. Disabling the constraints is accomplishedby disabling the FileTable's namespace. You will need to re-enable the namespacebefore the FileTable contents will be available again.Before the FileTable's namespace will be re-enabled (and the contents be available usingWindows APIs), SQL Server will perform a consistency check on the FileTable. If theconsistency check fails, then the namespace will not be re-enabled and the inconsistencymust be fixed.To disable a FileTable's namespace in SSMS, right-click on the FileTable, open the TableProperties dialog box, and go to the FileTable page. Change the value of the FileTablenamespace enabled option to False.The code in Listing 11-7 disables and then re-enables the FileTable namespace for theDocuments table. Barring a rogue DML operation that takes place between the disableand enable operations, this simple action will not result in inconsistencies.-- Disable the Documents FileTable namespaceALTER TABLE Documents DISABLE FILETABLE_NAMESPACEGO-- Enable the Documents FileTable namespaceALTER TABLE Documents ENABLE FILETABLE_NAMESPACEListing 11-7:Disabling and enabling a FileTable's namespace using T-SQL.Since disabling the FileTable namespace disables constraints, this should not be donewithout thoroughly considering the potential implications of data consistency problems.399
