Storing File As Binary Image Into SQL Server
Dec 21, 2005
I am using FileUpload control in ASP.net 2.0 to upload files and store them into SQL server database as an image. I am fine with MS office files, image files and etc. We have Product Center (Proe) engineering software to configure parts and the files generated through this software have PLT extension when I store these files, the file type is Plian/text. I am using Fileupload.PostedFile.Content to get the file type. How can I store PLT, TIF files in SQL server? Please help.

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.

I have a list of images in the file and I am supposed to display them. Can anybody please let me know what is the best way to do this?
Thanks a lot!!

I want to store Images as binary data in SQL table and compare it each time with a image file I am getting. I've tried below approach but getting error:
DROP TABLE #BLOBTest
CREATE TABLE #BLOBTest
(
TestID int IDENTITY(1,1),
BLOBName varChar(50),
BLOBData varBinary(MAX)
);
[Code] ....
Error: Msg 4861, Level 16, State 1, Line 10
Cannot bulk load because the file "C:Files12656.jpg" could not be opened. Operating system error code 3(failed to retrieve text for this error. Reason: 15105).

Is there any way to store a binary or image file into a database record / save a binary or image record back into a file using Transact SQL? If yes, would the "image" data type be most suitable?
(As a background, I am working on a process that deals with incomign emails, and I am using SQL Mail for that purpose. The above is needed to deal with attachments that may come with emails, and which are saved in a physical file on the HDD).
Thanks a lot in advance...

Hi There,
I am new to VC# and SQL Express. I am currently trying to find a way to store user selected files into SQL Express. I am using a column with the varbinary(MAX) data type. My current thought is to give the user a open file dialog box, and let them select the file they want to upload. On closing this dialog box, I convert the file selected into a file stream and insert into SQL Express.
Is this method a good one? If anyone else can give me pointers or hints to better methods, please do!
Thanks,
Ke

Hey everyone,
I'm deploying a desktop application with Sql CE 3.5. I have a collection of files that I would like to be save as a binary format in SQL CE. These files range from 1KB to 5MB. I know I cannot use varbinary(max) , instead I am limited to varbinary(8000), but this obvisously comes short of 5MB. There are articles stating to use the image datatype to get around this. Is this just bad practice, should I keep the files on the file system or take advantage of this work around? Do you have any suggestions?
Thanks in advance,
-- Chris

I seem to be getting very annoying behaviour from SQL Server and was wondering what the correct method should be...I want to store some binary data in the database and I want to use a stored procedure. I also want to pass some XML to the stored procedure where this XML contains the binary data. I will then use OPENXML to grab the binary data and stick in the table. In order to ensure the safe transmission of the binary through XML I Base64 encode it. Ok so far. The problem is that although OPENXML is supposed to assume that anything marked as Image/Binary will be Base64 encoded it then proceeds to Base64 encode it again and put that result into the database! So what am I missing, am I supposed use a CDATA section or something rather than Base64 encode my XML?

Hi I have an image column (Spectrum) in a Table (ParticleEDS) which is populated with an array of a bunch of INT32's (4 bytes each)
Using TSQL is there any way that I can read each 4 bytes (convert this to an INT) and return this data for a given record (based on ParticleEDSID).
I know that there are 2048 x 4 bytes that make up the image column.
I would like the output of the query/stored procedure to be:
Value
------------
1 2342
2 2334
3 3343
.....
2048 1001
thanks!

I have a table that contains the following two columns:BITS (image(16))BIT_LENGTH (int(4))When I look at the table, I see "OLE Object" in the BITS column. Whatsyntax should I use in a SELECT statement to convert the binary imageinfo contained in "BITS" into simple text that I can read? What roledoes the BIT_LENGTH field play?

Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?

1. How can I upload new pictures into the database through the browser.
2. Can you describe how the new picture of the product would be uploaded into the database.
3. How do you handle different formats that pictures come in gif, tif, jpeg,
etc.
4. How can you say that SQL server does support images well, because on
microsoft site they loaded up the satellite data of the earth into sqlserver
which is only picture data

Hi all,
I have got this issue when I am trying to store an Image on a database through a stored procedure. I give you the code in C# and the stored procedure
Code Snippet
//I have got these two variables with the ID(foreign key) and the array of bytes of the Image (the values are OK)
int ID_Inmueble
byte[] imagen -- dimension 26246
SqlConnection conn = new SqlConnection(...) //The conexion works fine (I tested it).
SqlCommand cmd = new SqlCommand();
SqlParameter[] param = new SqlParameter[2];
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "InsertaUnaFoto";
cmd.Connection = conn;
param[0] = new SqlParameter("@ID_Inmueble", SqlDbType.BigInt);
param[0].Value = ID_Inmueble;
param[1] = new SqlParameter("@Foto", SqlDbType.Image);
param[1].Value = imagen;
cmd.Parameters.AddRange(param);
SqlDataAdapter da = new SqlDataAdapter(conexion.GetSqlCommand());
da.Fill(ds); //here I got the error
The stored Procedure

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

Hi,
I'm storing thumbnails in SQL CE and accessing them from my WPF application. The save seems to take place ok and there's binary data in the image field however when it comes back out it appears to be corrupted somehow. Can someone have a look at the code below and verify I'm doing the conversion correctly before storing in my image field? Thanks!
- Roland
Code Snippet
private byte[] GetArrayOfPixels(BitmapSource bitmapsource)
{
Int32 stride = bitmapsource.PixelWidth * bitmapsource.Format.BitsPerPixel / 8;
Int32 ByteSize = stride * bitmapsource.PixelHeight * bitmapsource.Format.BitsPerPixel / 8;
byte[] arrayofpixel = new byte[ByteSize];
bitmapsource.CopyPixels(arrayofpixel, stride, 0);
return arrayofpixel;
}
//I assign the byte array returned to my datatable like so:
MediaAsset asset = new MediaAsset(){
Thumbnail =
new Binary(GetArrayOfPixels(Thumbnail as BitmapSource));
}
//then I insert it into my tables collection
myDB.MediaAssets.InsertOnSubmit(asset);
//and submit the change
myDB.SubmitChanges();
Am I not getting that pixel array correctly for storage?
Thanks for the help!

Hey all,
Just starting to investigate this. I need to store digital pictures in my database for use in claims and disputes. I have played a bit with the image datatype but notice that one picture takes up 1Mb as a TIFF and 3Mb as a JPEG. Does anybody work with this stuff and if you do what is the best picture format to use in regards to keeping clarity but minimizing size used in the db. Is there any load conversion routines that would shrink the size of the file.
Any suggestions or comments on this topic are appreciated.
Thx. Kelsey
