I would like to design a content-management feature on a website, in particularbe able to upload a binary file and to store it into a MS Sql Server DB.be able to download it afterwards. The sizes of the files are very limited (less than 100Kb) so I do not need any special feature to handle the upload/download.Does anyone know how to achieve such feature?Thanks in advance,Joannes

We have a simple table which we need to store logo's for a website. The table looks like this:
CLIENTLOGO (Tablename)
id (Bigint) (PK) - NOT NULL
StoredImage (Image) - NOT NULL
ImageSize (Integer) - NULL
Im not an expert on sql sorry!
I have two problems,
1. I need to upload some logo's (they are gif's if thats important)
2. I need to store the image size
I don't have a clue how to do 2 but ive tried the following for 1 but it doesnt seem to work
Insert into CLIENTLOGO (id, storedImageTablename)
Values (1, 'c:ClientLogo1.gif')
Can somebody help, im really confused about this one
Hello,
I am an ASP.NET 2.0/SQL 2005 web developer, and I have run into a huge frustration for some time now that I can't seem to get past. My goal is to develop SQL databases for my costomers on my development machine, and then upload the completed database out to my host. I have not found a host that allows this yet. Some hosts do not allow remote SQL connections altogether, and the best hosts I have been able to find allow remote SQL connections, but do not allow SSIS or DTS packages to run to transfer database objects to the production server.
What does this mean? Well, I have to manually transfer or recreate individual stored procedures and recreate primary, foreign, and other table constraints. I cannot just run a DTS package to transfer the completed objects. So this means duplicating effort, changes for mistakes, and more server downtime during site upgrades. I have called so many host providers, and I haven't found one that can get me past this.
Also, I contacted Microsoft to ask about Licensing (thinking I would just lease a dedicated server), and the only option I can use is SPLA licensing. The catch, I have to lease the OS through SPLA as well, and all the hosts I have contacted put the OS on the server themselves. This means I would be paying for the OS twice.
Ideally, I would just love to find a shared web host package that I could use efficiently with my SQL development. Am I missing something? If anyone has any advice, please help! I would be so appreciative!!! Thanks.
Regards,
Jeremy
I have a form that inserts text and also allows the user to upload 3 images. I have the text part working, but can't figure out how to get the images uploaded. Here is the form. I just inserted the 3 upload controls in the form and in the datasource to show what I am trying to do. If anybody can help me I appreciate it. 1 <h3><br />Add Listing</h3><hr />

i am using sql server,asp.net and C# language.I am able to upload data into the database but couldnt retrieve it from the database.i am using the following code to upload image into the database.kindly help.
SqlConnection connection = null; try { FileUpload img = (FileUpload)imgUpload; Byte[] imgByte = null; if (img.HasFile && img.PostedFile != null) { HttpPostedFile File = imgUpload.PostedFile; imgByte = new Byte[File.ContentLength]; File.InputStream.Read(imgByte, 0, File.ContentLength); } string conn = connection establishing string; connection = new SqlConnection(conn); connection.Open(); string sql = "insert into imagetable values(@enm, @eimg) SELECT @@IDENTITY"; SqlCommand cmd = new SqlCommand(sql, connection); cmd.Parameters.AddWithValue("@enm", txtEName.Text.Trim()); cmd.Parameters.AddWithValue("@eimg", imgByte); int id = Convert.ToInt32(cmd.ExecuteScalar()); lblResult.Text = String.Format("Employee ID is {0}", id); } catch { lblResult.Text = "There was an error"; } finally { connection.Close(); }
My hosting gives me ASP.NET 2.0 and a shared SQL Server 2005 package.
I have Visual Studio 2005 on my machine - which installs SQL Server 2005 Express. I have also installed SQL Server 2005 Management Studio Express.
I wish to develop my database locally (mdf file) as I won't always have internet access (and therefore can't always work directly with the remote shared database).
My question is, how do I upload my database info from my local machine to my remote shared database?
Also I shall wish to download my remote database to my local machine in order to work on the database (and then be able to re-upload it) sometimes.
Please can somebody tell me how I can do this?
Will SQL Server 2005 Management Studio Express permit me to do this and if so how?
If I need the full version of SQL Server 2005 Management Studio then I do have SQL Server 2005 and this install with it (but it all looks a bit complicated to install for me).
Many thanks for all help given,
Graham

View 13 Replies View RelatedHi there :)
I'm in the final stage of my asp.net project and one of the last things I need to do is add the following file information to my SQL server 2000 database when a file is uploaded:
First of all I have a resource table to which I need to add:
- filename
- file_path
- file_size
(the resource_id has a auto increment value)
so that should hopefully be straight forward when the file is uploaded. The next step is to reference the new resource_id in my module_resource table. My module resource table consists of:
- resource_id (foreign key)
- module_id (foreign key)
So, adding the module_id is easy enough as I can just get the value using Request.QueryString["module_id"]. The bit that I am unsure about is how to insert the new resource_id from the resource table into the module_resource table on file upload. How is this done? Using one table would solve the issue but I want one resource to be available to all modules - many to many relationship.
Any ideas?
Many thanks :)

I have googled many web sites,but i can't find the help that how to upload or store files(include images) into a database with Asp.Net 2.0.
Although i have found few samples about storing images into database,but the sample applied with Asp.Net 1.0 or 1.1 technology...
In microsoft MSDN,i found the help about FileUpload control,but the sample is about how to upload files to servers's folder with saveas() method.
Who can help me ?Give me a refer sample about upload files to database with Asp.Net 2.0. Is it need to use stream or what other method?
By the way, i want make a document managment system with vwd and sql express.
Thank u very much if u can give me a help.
I have recently designed and built my first database using SQL server 2005 express. I have included an image (BLOB) column in one of the database tables. This is a bad idea according to some experts, and some say it is OK!
I am currently carrying out a trial with just 3 pictures via Visual Basic 2005 express forms, and there is no problem so far as the images are displayed for each record. But I anticipate between 300 - 1000 images for the table, and this could pose real problems for SQL server 2005 express and Visual Basic 2005 express, I guess.
I have just been reading that the cost of storing large images in the database is too high! I have also read it's better to store images (BLOB) into the file system because it is cheaper to store them no matter how many there are.
But the question is how I can reference an image in this path: C:PictureProductGrocery 0052745.jpg in the database table, so that when I select a record Visual Basic 2005 forms the image is displayed accordingly, similar as when stored directly in the database table? Your help very much appreciated.
Hi there,
I have inherited a databse and am building a new website to go wiht it.
There is a file upload page which will upload images to a directory. I need to insert into the database retrieve the id just added then upload the image renaming it in the format locID(QueryString)_ImageID(retrieved from database).jpg
The page has a file upload control and a button.
I am trying to write my code behind so that when the button is clicked it inserts location id into the images table retrieves Image id. Renames the file and uploads it to the images folder.
II think i need to call the routine from another routine for the button click but the signatures are different, where am i going wrong? or for that matter have i been pissing into the wind for the last 4 hours?

Can anyone give me an example of how to Upload a file to SQL in asp.net 2.0 using VB?
Thanks

Hello
I am using Microsoft SQL Server Management Studio Express and want to insert a row into a table. The table (Pictures) has the following columns: ID (int), Filename (varchar), Data (varbinary).
INSERT INTO Pictures(ID, Filename, Data) VALUES
(12, 'photo.jpg', C:photo.jpg);
The statement above does not work. How do you do it?
Thank you
Can someone please direct me to a discussion on which version of SQL Server allows a file to be stored in a db field and how this is accomplished as well as how the file is then retrieved with asp.net VB from the DBthanksMilton

My problem is that the upload works in testing for our asp.net site only for dbo. Being mindful of security, I would prefer not use this account to execute all sp_/sql. One solution could be using impersonation only in the content management system where the uploading is done, this is code in web.config:
<location path="Manage.aspx"> <system.web> <identity impersonate="true" userName="dbo" password="****" /> <authorization> <deny users="?" /> </authorization> </system.web> </location>
To do this I would have to change the dbo password as set up by previous employee, not a real dba so not sure of the implications (enough permissions to be dangerous though;). Is the above impersonation ok, or should I redo logins security in sql? Thanks.
Here's what I have to do:1. Allow user to locate a .xls file on their machine2. Upload this .xls data into an existing table on a remote SQL ServerI can pull the file from my local machine to another directory on the local machien, but can't figure out have to configure the saveas() to save on the remote db server.It seems you have to save the the db server first on the hard drive, then you can insert the .xls file data into the table.Here's my code so far that works to save on the local machine to another directory on that local machine:Dim getmyFile As HttpPostedFile = myfile.PostedFileIf IsNothing(getmyFile) ThenLabel2.Text = "Please select a file to upload"ElseIf getmyFile.ContentLength = 0 ThenLabel2.Text = "Cannot upload zero length File"ElseDim ServerFileName As String = Path.GetFileName(myfile.PostedFile.FileName)getmyFile.SaveAs("C:TestSaving" & ServerFileName)Label2.Text = "Successful upload to C:TestSaving" & ServerFileNamesCon1.Open()Dim strSQL As StringDim err As IntegerstrSQL = "Insert into ActivityTest Select * FROM OPENROWSET"strSQL &= "('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=D: esting.xls;"strSQL &= "HDR = YES ','SELECT * FROM [Sheet1$]')"Label3.Text = strSQL.ToString()Dim cmd As New SqlCommand(strSQL, sCon1)Trycmd.ExecuteNonQuery()err = "Select @@Error"If err <> 0 ThenLabel4.Text = err.ToString()ElseLabel4.Text = "No Error...line 91!"End IfCatch ex As ExceptionLabel2.Text = "Line 82 Error Updating Table: "Label2.Text &= ex.MessageFinallysCon1.Close()End TryEnd IfThanks for the help in advance!!!!

I'm looking for a way with Integration Services in SQL'05 to upload a file. How could I do this? Is there any examples out there?
This partuclar HTTP Server has WEBDAV configured so if I could just point to the URL location and new FILE that would be excellent.
Thanks
Hi,
I uploaded an xlsx file to my reporting services. When i click on the xlsx file link in the reporting services frontend, a internet explorer window is opened with the xlsx file information (reporting services) and the xlsx file is opened by the excel application.
Is there any way to prevent the Internet explorer window to be opened?

Hi guys,
I want to update a PDF file and store it in the MSSQL database. (I know it is better if I save the file on server and just store the link to it, but I have to store the file on the database "Project Requirements")
I would probably use FileUpload control to upload the file. but would I upload it to server temporarly and then save it or would I just upload it to DB.
I appreciate your help and suggestions and any tips & tricks or issue that I have to consider.
Regards,Mehdi
