Image Files And SQL Server

Jul 20, 2005

Hello,
What's the best way to store files of an arbitrary size in a SQL
Server / MSDE database? Some files will be text, but most should be
binary (images, audio, and video). I'd like to be able to store all
the files directly in the database so that backing everything up is a
single operation (I can do this, right?). Data retrieval speed is not
overly critical, as the code in question will be running on the same
machine as the database and will only have a single instance of the
client application. Any advice and/or hyperlinks to whitepapers on the
subject would be appreciated.

Thanks,
Will Gant

Help!!

I need to store a few thousand images in a sql server database.

At the moment we're using Notes and its great 'cos you just cut and paste them in. But now we need to take them all out and put them into sql server it's proving to be a nightmare. Any clues anyone??

Retrieving MSG Files From SQL Server Image Column

Dec 3, 2007

As part of a web site I allow users to store documents in SQL Server 2000 using an Image column on a table. After the file is saved the user can open the document through the browser. This works great for most file extensions such as ".XLS" or ".DOC" but fails when attempting to open ".MSG" files (saved outlook messages). XLS documents will open in Excel and DOC documents open in Word, but MSG documents open in Notepad and display what appears to be binary data. I'm trying to figure out if this is a SQL Server issue or some sort of ASP/ASP.NET webserver issue.

If I attempt to open an MSG file stored directly on the web server, the file opens correctly using the "Microsoft Outlook View Control", but when attempting to open the same file saved in SQL Server, it attempts to open in notepad.

Any ideas?

Process Many Image Files And Wav Files

Dec 11, 2005

I need to write codes to access many image files and wave files and display them on the webpage. Both of these files are stored on the server (as many experts in this forum adviced) and their locations are in the SQL server database. About the wav files, I think I will have to convert them to MP3 first for fast delivery on internet. Since I am a newbie, any help would be appreciated.

Storing Files In Image Columns In 2005

Jul 10, 2006

I did some quick Googling and didn't find the article of my dreams here. Any experience with storing files in the db in 2005? Any opinions?

Here's the deal. We have our new 'Enterprise' software being designed and written in St. Petersburg (not FL) and I'm reviewing the design for dealing with letters and forms that are generated as hard copy from our business (by the thousands per month) and sent to clients for review, signature etc. Then they are returned by fax or snail mail.

The current design has all of these being stored in image data type columns in the database--storing saved files of the actual outgoing stuff and saved files of the stuff that comes in (scanned copies or the files from our fax server).

This screams 'BAD IDEA' based on our experience doing this in SQL Server 2000. We get things like 23 page faxes from Dr's offices, large packets of FMLA forms returned, etc. In 2000 they tended to get rather large when stored in the DB and caused us all kinds of headaches when Microsoft changed how it recognized and displayed certain types of files, e.g. tiffs.

Further, the outgoing stuff is largely boilerplate with added fields from the db--name, address, a few dates. My proposed design for outbound notifications and forms was to keep only references to the template used, the date created, and an id to link it to the personal info of the schmoe to whom it was sent--essentially, store which document template and then just enough data to map to the variable content that is pulled from the db. Then you can recreate the file that was printed and mailed at any time in the future, but you don't actually save the .doc (or Word .xml) anywhere, not in the file system, not in the db.

The current developers feel this is way too much work to design--and it is certainly more effort than just generating .docs/.xml files via a merge with Word and then stuffing those into the database. They also argue that having them in the db makes them 'more secure' and more 'accessible' to users around the globe.

Does anyone know if the image storage is any better in 2005 than 2000? The .docs & .tifs we used to store just about tripled in size when we put them in the db in 2000. Plus there were the defrag issues and generally it was an unsatisfying experience.

Does anyone know what the advantages/disadvantages of generating Word .xml files might be? Can they be stored as xml data type in SQL Server? Perhaps this is a better option?

If anyone has the time to digest this, please send opinions.

Thanks!

I need to store the Image file in the photo field so that I can run reports in reporting services and so on and so forth. I am not sure how to complete this task.

Sending Uploaded Image To Data Access Class When Storing Image In SQL Server 2005

Apr 20, 2007

I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

Accessing Image Files Stored As Binary Data

Jul 11, 2006

Hi
When images are uploaded and stored directly into a sql database as binary data (eg in the club starter kit) how can those images be accessed and displayed.
When I open the images table in VWD  and select display data, the cells holding the image data hold a <binary data> tag. What I want to be able to do is get at that data, or actually get at the image so that it is displayed. My reason is this, at the moment the only way to access the images in the sql database after they have been uploaded is to log into the website and view them as an administrator of the site. It would be much simpler if I could access the database directly and view the contents of the images table.
Any ideas?
Thanks

How To Load/Unload Non-Graphical Files Into/From IMAGE Field?

Dec 13, 2007

I want to be able to load and unload, byte-for-byte, a file to and from a field of data type IMAGE in a SQL Server CE database. The files are larger than 8000 bytes so IMAGE appears to be the way to go data type wise.

I'm using VB 2008 but pseudocode for any VS language would be awesome.

I was able to do this without much effort using ADODB and its stream object, fetching a recordset object and updating the appropriate data field one "chunk" of bytes at a time. I cannot for the life of me find a way of doing this using, for example, a SqlCeResultSet.

I've tried using ADODB to connect to a SqlCe SDF database file, using a connection string that I found online, and am able to write action and select queries successfully against the database... but when I try and return a recordset that is updatable, it returns an error. So no help there.

I've searched other threads in the forums, and online in general, and I've found information on loading/unloading graphic files using a memoryStream and the toArray method thereof, but this will not work as many of the files I want to load and unload as BLOBs are not graphical in nature. FileStreams do not implement the toArray method, so I can't just stream an arbitrary file's worth of bytes that way. I also do not want to change the original file in any fashion--e.g., a hash of the source file should be identical to the file after it has been loaded into the data field and then unloaded into a new file.

Any thoughts? Your help is MUCH appreciated!

HOW To Retrieve An Image From Sql Server And Display It In ASP.net Using Imagemap Or Image ?

Jul 6, 2006

Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.

using the following vb.net code:

'Dim sel2 As String

'Dim myCom As SqlCommand

'Dim conn As New SqlConnection

'Dim drr As SqlDataReader

'Dim image As System.Drawing.Image

'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "

'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")

'myCom = New SqlCommand(sel2, conn)

'conn.Open()

'drr = myCom.ExecuteReader()

'If drr.Read Then

' Me.ImageMap1.ImageUrl = drr.Item("attach")

'End If

'conn.Close()

Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")

saying: Conversion from type 'Byte()' to type 'String' is not valid.

knowing that i tried converting using ToString but it's not getting any output then.

Linked Server To Text Files: Is Possible To Detect Changes Made To Those Files? (SQL Server 2005)

Sep 3, 2007

Hi gurus,

I've created a linked server (and set up the corresponding schema.ini file) in order to perform bulk-inserts from some CSV text files into SQL tables (from my standpoint the text files are just for reading purposes). The linked server works fine (I can select the data in the files without a problem).

Now the question: is possible to automatically detect when one or more of those files change in order to start the import process automatically? Something like having a trigger created on the CSV files Or there's no easy way to do that so I have, to say something, to create a Job that periodically checks if the files have changed programatically (say, recording each file's timestamp everytime is imported and comparing the recorded value with the current one, or whatever)?


Thanks a lot in advance!

SQL Server Admin 2014 :: Separate Data Files / Log Files / TempDB / Backups

Jan 9, 2015

I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.

1st Image Control Shows Wrong Image

Jan 30, 2007

In my asp.net application I have a local report with an image control in thedetail row of the table and the Value attribute set as="File://" & Fields!FQPhotoFileName.ValueThe first row in the table always shows the wrong image and it's always thesame wrong image. The problem is there even when I change the sort order orthe criteria for the underlying dataset. For example, I ran a small testthat populated the dataset with 2 rows and 2 images. When I sort by anycolumn (e.g. ID) in ascending ascending order the ID=1 row (the 1st row)shows the wrong image and the ID=2 row shows the correct image. When I rerunthe report sorting in descending order the ID=2 row (which is now the 1strow) shows the wrong image and the ID=1 shows the correct image.Any suggestions?

Inserting Image Data Type From SQL Server CE To SQL Server 2000.

Oct 23, 2006

Hi All,

I am manually replicating parts of a SQL Server CE database (running windows mobile 5.0) to a centralized SQL Server 2000 database.

My program is throwing an exception whenever I try to insert an image data type into the 2000 server from the PDA. I am using parameterized queries.

Error is as follows:
[error]
System.Data.SqlClient.SqlConnection.OnError()
at
System.Data.SqlClient.SqlInternalConnection.OnError()
at
System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()
at
System.Data.SqlClient.TdsParser.Run()
at
System.Data.SqlClient.ExecuteReader()
at
System.Data.SqlClient.ExecuteNonQuery()
at
PDASync.Database.ExecuteIDRemote()
[/error]

The code for my ExecuteIDRemote method works fine for other queries. It also works if I remove the image column from the offending query.

Does anyone have any suggestions? Thanks.
