Using just an sql query is it possible to write the contents of a varbinary cell to the file system? I have a column that stores pdf s as and for some quick testing I'd like to write out the pdfs to the filesystem.
Thanks for any help.

How to dump all of our images from a VARBINARY(MAX) field in SQL Server 2008 to the filesystem?
You'll need to iterate through each row and perform a BCP (BulkCopy) Dump of each varbinary field to the filesystem

If I create a FileTable in SQL server 2012, and then was to drop a 4G file onto the NT filesystem (that was in the filestream), would that entire 4G file be read into the table's filestream column?
Is SQL in fact making a COPY of my 4G file? Or does the filestream column represent a pointer to my 4G file, which it begins to read on a query?
Im just trying to figure out if I added 100G of data to my file system, would that add 100G of data size to my DB.
Can someone help explain how this works? And even better point me to some docs with more detail than the MS/MSDN 'how-to' stuff?
The file table stream is stored separately in individual files using the SQL Server FILESTREAM feature, not in the normal SQL Server data files. These files are managed internally by SQL Server.
You can consider the file_stream column similarly to a pointer to the file. The file stream is still part of the database, though, and will be backed up along with the rest of the database.
No, your 4 Gb file will be stored only once, as a file on disk. Sure, there will be some small amount of metadata stored in the database, but that's all.

Is it possible to compress data (programmatically) in SQL Server using zlib compression? It's just one column in a specific table that needs compressing.
I'm not a SQL Server person myself - I've tried to find if there's anything available but not had much joy.
Thanks
I have a large set of CSV files which I am transferring to Microsoft SQL Server 2014 Management Studio. I am using a SSIS package in Microsoft Visual Studio 2012 to achieve this. I currently have around 2 million lines of data so I need SSIS
The problem I have is that while the data in my CSV already has encoding issues I am making them far worse in transit.
For now what I need to do is just maintain the characters so that whatever I see in my CSV appears in my SQL server table. I am particularly interested in 'Benoît' which is fine in my CSV but not in my SQL table where it becomes 'BenoŒt' Please see the list at the bottom of my post.
I am also wondering if once I have imported the data in its current state I can reliably use find and replace to deal with the existing encoding issues from my CSV's
Character encoding is a confusing subject and I am not all sure if a couple of paragraphs can put me on the right track. Please help with a steer (if its possible!) I am sure I need to look at the settings across both SQL server and Visual studio but am not sure what needs a tweaking or where..
"Benoît" in my CSV becomes "BenoŒt" in my SQL table
"Angélique" in my CSV becomes "AngÇŸ¶¸lique" in my SQL table
"Michèle" in my CSV becomes "MichÇŸ¶ùle" in my SQL table
"josée" in my CSV becomes "josÇŸ¶¸e" in my SQL table
"Amélie" in my CSV becomes "AmÇŸ¶¸lie" in my SQL table
First of all make sure that your CSV files are in the Unicode encoding (try to open CSV file in the Notepad-> Save As -> and check Encoding in the bottom). If they are not - save them in Unicode
And make sure that in the Flat File Source properties inside SSIS packege the Unicode check box is selected
Your csv file needs to be in UCS-2 Little Endian encoding.
Please open it in notepad++ to check.
In SQL Server database we have files stored in a table.
We want to extract files from DB to filesystem
The files are html, xls, pdf, image formats.
Please advise options to retrieve information with minimum programming effort.
Can this be done directly from database using some SQL function / TSQL code?
Can this be done by ASP.net?
Can we export records as XML file and work on the attachments?
Thanks.
If data is stored as BLOB, then you can simply query that column like any other column in SQL Server. And if you are using Filestream to store files into file system, then this MSDN Magazine article should help you.
I want to transfer data from an SQL Server 2008 R2 database to a Oracle 11g Database, A very straightforward ETL operation. But in the SQL Server a Database is using the Filestream functionality to store certain videos and images, but the Oracle database does not have this functionality to my knowledge.
Is there anyone out there who has come across this kind of situation earlier? What was the solution you applied? Simply stored the binary files in a separate server or simply used the BLOB type to store the files?
Thanks in advance....
It sounds like you are looking for the BFILE type. This is an Oracle data type that allows you to work with binary data that is stored on the file system outside the database.
