One of the problems I came across while writing the partitioning chapter for my FILESTREAM book is that the partitioning does not work correctly with RANGE LEFT. It works as expected when using RANGE RIGHT. Something is wrong with RANGE LEFT and the problem exists in SQL Server 2008, R2 and Denali CTP1...

This post tries to explain the behavior of differential backups on a FILESTREAM enabled database. A number of times, I see questions looking for a confirmation whether Differential Backups will correctly backup the NTFS (FILESTREAM) files and restore them correctly when a differential backup is restored...

This post shows a quick and dirty way of loading a huge file into the FILESTREAM column of a SQL Server 2008 database instance. Note that this is an unsupported method which is not recommended on a production server. The correct way of loading BLOB data into a FILESTREAM column The right way of loading...

I have been playing with FILESTREAM backups for a book that I am writing and came across something that I did not really like. I observed that a FILESTREAM backup may include garbage files which gets restored along with the database. What are garbage files? Let us understand what are garbage files. SQL...

One of the questions that might come to your mind while getting started with FILESTREAM is the way FILESTREAM directories and files are named. Within the FILESTREAM Data Container, SQL Server creates a root folder per FILESTREAM enabled table. If the table is partitioned, a folder will be created for...

Configuring a software feature is usually much harder than removing it. Most of the times, removing a feature could be just a matter of a mouse click or a simple command/statement. So what do you think about this question? Enabling FILESTREAM storage on a database and removing it completely from a database...

Excepts from a conversation between Sumit and Leena, that I overheard last week. Don’t know who they are?? Never mind, I will introduce them later! Leena : “Sumit, I am playing with the FILESTREAM access level and I am bit confused as I am getting a ‘3’ while querying!” Sumit : “I warned you not to play...

This post looks closer into a common problem many people may have faced while storing Microsoft Office documents into the FILESTREAM column of a SQL Server database. I heard this question recently on one of the forums. The situation is as follows: Save an Excel 2003 document in a FILESTREAM column Read...

This white paper describes the FILESTREAM feature of SQL Server 2008, which allows storage of and efficient access to BLOB data using a combination of SQL Server 2008 and the NTFS file system. It covers choices for BLOB storage, configuring Windows and SQL Server for using FILESTREAM data, considerations...

When a VARBINARY(MAX) column is marked with the FILESTREAM attribute, the limitation of 2GB is not applicable on the value any more. You can store values larger than 2GB in such a column. The maximum size is limited only by the size of the disk. A FILESTREAM column can be accessed from TSQL, just like...

This question was asked in the comments section of my FILESTREAM article at simple-talk.com . I thought it may be a better idea to write a detailed blog post explaining it along with some sample code, rather than writing a short answer in my return comments. I created a small ASP.NET example to demonstrate...

I had been blogging a bit about the FILESTREAM feature of SQL Server 2008 recently. I have just published a rather long article on FILESTREAM, at simple-talk.com. You can read the article here: http://www.simple-talk.com/sql/sql-training/an-introduction-to-sql-server-filestream/ The article covers the...

I see this error reported many times in the online forums. This usually happens if you try to create a FILESTREAM enabled table in a database that is not configured for FILESTREAM usage. To be able to store FILESTREAM data in a database, the database should be created with a FILESTREAM file group. This...

“Well, when accessing from TSQL, FILESTREAM enabled columns are not different from other regular columns and the code is not different from the regular code that you write”. This used to be my usual answer to people who ask me this question. I also had a standard piece of sample code that looks like...
