Chapter 11: FileTableNow open (or return to) SSMS and select all rows from the Documents FileTable. Youwill find that one row is returned. You can verify the value of the name column to makesure the correct file is returned. Also note the value of the cached_file_size column,which should read 0 (as the file is empty). A full discussion of the FileTable schema isincluded above.It is possible that you set a value for the FILESTREAM Non-Transacted Access toReadOnly. In that case, you will not be able to create new files. Windows Explorer willshow an error message like the one in Figure 11-6.Figure 11-6:Windows Explorer error message if FILESTREAMNon-Transacted Access is set to ReadOnly.The error message states that destination folder access is denied, but there really isn't apermission issue. It may be more constructive to think about it as a configuration issue.If you successfully created the new text file, open it in your favorite text editor (which islikely not FILESTREAM-aware!) and add some text to the file. Use the Save command inyour text editor to save your changes. Rerun the SELECT query in SSMS and review theresults.
