Thismenu option will be grayed out if the database is not set up for non-transactional accessor if the FileTable's namespace is disabled.Adding constraints to the FileTableIt's not possible to create constraints on the FileTable at creation time, but you can addconstraints later, using an ALTER TABLE statement. Note that you cannot remove theconstraints that are created by default.By way of example, let's add a constraint to the FileTable that would prevent files frombeing created at the FileTable root folder. A constraint like this might be useful if youhave defined folders in the FileTable and you do not want users to create files unlessthey're in one of those subfolders. Listing 11-15 shows how to define such a constrainton a FileTable.ALTER TABLE DocumentsADD CONSTRAINT CK__Documents__NoFilesInRootCHECK(is_directory = 1 OR path_locator.GetLevel() > 1)Listing 11-15:Creating a constraint on a FileTable.409
