View 1 RepliesIs 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).

View 3 Replies View RelatedHi 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,

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,

hello.
i have a _CommandPtr that has the type CommandTypeEnum::adCmdTex, and the CommandText a query("Select * from Table_1") and this select returns one row that has a binary data in it.
Code Block
_CommandPtr pCommand;
//Create the C++ ADO Command Object
pCommand.CreateInstance(__uuidof(Command));
pCommand->ActiveConnection = this->pConnection;
//Make the ADO C++ command object to accept stored procedure
pCommand->CommandType = CommandTypeEnum::adCmdText;
//Tell the name of the Stored Procedure to the command object
pCommand->CommandText = _bstr_t("select * from Table_1");
//get recordset
pRecordset = pCommand->Execute(NULL,NULL,CommandTypeEnum::adCmdText);
BYTE* buffer = NULL;
if(pRecordset != NULL)
{
while (!pRecordset->GetEndOfFile())
{
VARIANT var = pRecordset->Fields->GetItem("test")->Value;
void * pData = NULL;
SafeArrayAccessData(var.parray, &pData);
long size = GetArraySize(var, NULL);
buffer = new BYTE[size];
memcpy(buffer, pData, size);
SafeArrayUnaccessData(var.parray);
pRecordset->MoveNext();
}
pRecordset->Close();
}
where:
Code Block
long GetArraySize(const VARIANT& var, long * nElems)
{
if ( !(var.vt & VT_ARRAY) ) return -1;
long size = 0;
long dims = SafeArrayGetDim(var.parray);

long elems = 1;
for ( long i=1; i <= dims; i++ )
{
long lbound, ubound;
SafeArrayGetLBound(var.parray, i, &lbound);

elems *= (ubound - lbound + 1);
}
if ( nElems ) *nElems = elems;
size = elems*elemSize;
return size;
}
I enter in VARIANT var = pRecordset..... and if gives me a value... but when I put it in Memory explorer in VS, i only see this data " fe ee fe ee fe ee fe ee fe ee fe ee fe ee ...fe ee" and of course it brakes at
SafeArrayGetLBound(var.parray, i, &lbound);
Can someone tell me where I am doing a very bad thing?
P.S. I was able to read the binary data from the server using C#.NET 2.0.
Hi I've followed a tutorial on how to write and read varbinary(max) data to and from a database. But when i try to read the data i get the error that the data would be truncated, but only when the varbinary(max) is greater then 8kB. I've used a system stored procedure (sp_tableoption) to set the table that holds the data to store data outside rows. To select the data i'm using a stored procedure: SELECT imageData , MIMEType FROM Pictures WHERE (imageTitle = @imageTitle) And then using an .aspx page to Response.Write the data:Using conn As New sql.SqlConnection conn.ConnectionString = ConfigurationManager.ConnectionStrings("myConnectionString").ToString Dim getLogoCommand As New sql.SqlCommand getLogoCommand.CommandType = Data.CommandType.StoredProcedure getLogoCommand.CommandText = "GetPicture" getLogoCommand.Connection = conn Dim imageTitleParameter As New sql.SqlParameter("@imageTitle", Data.SqlDbType.NVarChar, 200) imageTitleParameter.Value = Request("imageTitle") imageTitleParameter.Direction = Data.ParameterDirection.Input getLogoCommand.Parameters.Add(imageTitleParameter) conn.Open() Using logoReader As sql.SqlDataReader = getLogoCommand.ExecuteReader logoReader.Read() If logoReader.HasRows = True Then Response.Clear() Response.ContentType = logoReader("MIMEtype").ToString() Response.BinaryWrite(logoReader("imageData")) End If End Using conn.Close() End Using Can anyone please help me with this?!

Application is ocr'ing tiff image files and then storing the resultant text data in a text field in SQL 2005 database. This field is then used with the full text catalog.
All works fine,
However, am I using the correct field type to store the text files for efficiency and space saving?
If I use a binary field, does this reduce the size of the database by compressing the text data in the binary field? Also, is there a limit as to the size of text file that I could store in a binary field?
It would be good to get feedback on this before I go too far down the wrong road.
So, text field to store the text data or binary field to store the actual text file?
Hello, I have a table that stores binary files. When I serve them up to the user, I call the following page (serveDocument.aspx?DocumentID=xxx) which holds only the following code and pass the document ID: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim DocumentID As Integer = Convert.ToInt32(Request.QueryString("DocumentID")) 'Connect to the database and bring back the image contents & MIME type for the specified picture
Using myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("kelly_lmConnectionString1").ConnectionString) Const SQL As String = "SELECT [Content_Type], [Document_Data] FROM [lm_Service_Detail_Documents] WHERE [Document_id] = @Document_id"
Dim myCommand As New SqlCommand(SQL, myConnection) myCommand.Parameters.AddWithValue("@Document_id", DocumentID) myConnection.Open() Dim myReader As SqlDataReader = myCommand.ExecuteReader If myReader.Read Then
Response.ContentType = myReader("Content_Type").ToString() Response.BinaryWrite(myReader("Document_Data")) End If
myReader.Close()
myConnection.Close()
End Using End Sub It works perfectly. But heres the thing: I want users to be able to right click on the link and chose 'Save Target As'. In IE 7, this works fine. In FireFox it saves the document as 'serveDocument.aspx'. Is there any way to inject the filename that I want to save the document as? Thank you.

View 2 Replies View RelatedI work for a company that makes heat transfers for the imprinted apparel market. We're developing a database of merchandise images for all of our non-design inventory. Using Access we're going to be inserting thumbnails of psd (photoshop) files. We're wondering if there is any way to import multiple psd's into the sql server database into matching records like matching a column named "filename" and the actual filename of the file without having to upload each file individually. We want to be able to dump the files from the database of the matching records, also. This way, once our catalog designer has found which designs they need to put into the new catalog, it will dump the psd's for us. The same for our staffer who does color separations.
Any suggestions out there? If you need me to post further of what we're trying here, I will. This is for the bossman.

Hey I currently have a foreach loop container working which scans a folder, loops through the files in this folder and then moves them to a new folder.
At the same time I also do an SQL insert into a table logging the details of the transfer.

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
We run std 2008 r2, I need to recreate flat files from their varbinary(max) equivalents in our db. I have a mix of excel, pdf, word etc to recreate. Will ssis be a good tool for doing this? I'm wondering what transform(s) would be involved.
Perhaps I need to cast to varchar 1st and then land the data but if I recall correctly there is a maximum record length in ssis destination flat file rows. And I'm thinking I would have to map the varbinary (or cast equiv) to a row in the destination once for each file created.
Hi,
I have asked this question on 3 forums now and never get an answer, I don't know what is so hard about this question but I will try it here.
I am using SHA512 in C# to convert a password and its salt to hashed. I need to store the password hash and the salt hash in the database in two fields. I was told to use binary field to store the hash data and that the output of SHA512 would ALWAYS be the same no matter how long the password is.
I modified this hash example to use only SHA512 and to work with byte array instead of plain text.
All I need to know now is what size I need to make my binary field to hold this password that is hashed.
http://www.obviex.com/samples/Code.aspx?Source=HashCS&Title=Hashing%20Data&Lang=C%23
Say I have a password which is 30 characters max, and a salt which is 16 characters max. The password and the hash are stored in seperate fields in the same table. They are both hashed using SHA512 and are both being stored as byte arrays in C#, what size to I need to make the binary data type in order to hold the password, and to hold the salt.
Thanks!

Can anyone point me in the right direction to find documentation for the problem below?I need to store and retrieve ten fields of 16-bits each for testing 16 true-false conditions (a total of 160 bits in each record) so I think I'd like to use ten 2-byte binary fields (160 "bit" fields would be quite unmanageble, if even possible [I think there is some kind of limit to the number of fields in a single record]). I'm not quickly finding in the SQL Server's online documentation how to test for, use and update binary fields. I'll keep looking, but can anyone point me in the right direction? I'm using VB, if that makes any difference.
