This hierarchy starts from a root directory that you specify when you create the FileTable.Įvery row in a FileTable represents a file or a directory.Įvery row contains the following items. It stores data related to all the nodes in that hierarchy, for both directories and the files they contain. A FileTable is a specialized user table with a predefined schema that stores FILESTREAM data, as well as file and directory hierarchy information and file attributes.Ī FileTable provides the following functionality:Ī FileTable represents a hierarchy of directories and files. SQL Server provides a special table of files, also referred to as a FileTable, for applications that require file and directory storage in the database, with Windows API compatibility and non-transactional access. At the same time, they can maintain Windows application compatibility for their existing Windows applications that see this data as files in the file system. ![]() Enterprises can move this data from file servers into FileTables to take advantage of integrated administration and services provided by SQL Server. Thus FileTables remove a significant barrier to the use of SQL Server for the storage and management of unstructured data that is currently residing as files on file servers. Support for Windows file and directory management APIs.Ĭompatibility with other SQL Server features including management tools, services, and relational query capabilities over FILESTREAM and file attribute data. Storage of file attributes, such as created date and modified date. Non-transactional streaming access and in-place updates to FILESTREAM data.Ī hierarchical namespace of directories and files. Windows API compatibility includes the following: Windows API compatibility for file data stored within a SQL Server database. The goals of the FileTable feature include the following: To learn more about FILESTREAM, see FILESTREAM (SQL Server). The FileTable feature builds on top of SQL Server FILESTREAM technology. In other words, you can store files and documents in special tables in SQL Server called FileTables, but access them from Windows applications as if they were stored in the file system, without making any changes to your client applications. FileTable lets an application integrate its storage and data management components, and provides integrated SQL Server services - including full-text search and semantic search - over unstructured data and metadata. The FileTable feature brings support for the Windows file namespace and compatibility with Windows applications to the file data stored in SQL Server.
