In my previous post I talked about the basic idea of what FILESTREAM is.
The sales pitch if you will. In this post I thought I would talk about how to
actually implement FILESTREAM?. It's
actually really easy.
FILESTREAM's live in a filegroup. Semantically, anyway. You will
define what folder the data sits in.
ALTER DATABASE Production ADD FILEGROUP
FileStreamGroup1 CONTAINS FILESTREAM; GO
Simple enough. Next you add a file to the filegroup.
ALTER DATABASE Production ADD FILE (
NAME = FSGroup1File, FILENAME = 'F:\Production\FSDATA') TO FILEGROUP
FileStreamGroup1; GO
Again, pretty simple. You'll notice the F:\Production\FSDATA. That’s
where the files are stored. Now, lets create a table that holds the FILESTREAM.
CREATE TABLE DocumentStore
( DocumentID INT IDENTITY PRIMARY KEY,
Document VARBINARY (MAX) FILESTREAM NULL,
DocGUID UNIQUEIDENTIFIER NOT NULL ROWGUIDCOL UNIQUE DEFAULT NEWID
()) FILESTREAM_ON FileStreamGroup1; GO
And that's it. To insert data into the table, do it like you would any
VARBINARY data.
