How To Store Uploaded Files In An SQL Database?
Apr 11, 2007
Hi Friends
Can anyone tell me how to store uploaded files from the user to the SQL database and later give an option of downloading the file probably in the form of a GridView control. How do we write code to allow the user to download the uploaded files. I have written code to upload and store the files into a folder, however, I'm not able to collect data from the folder later and the folder is only accessible offline using the server system which I do not want to happen.
Can anyone help me with this?
Thanks

In our new app, a user is given the option of uploading one or files to the server and saving the filename and path to the database.
We would like to display all files associated with a particular user.
Obviously, the code below is only displaying one file.
How to display all files associated with a particular employee?
select ROW_NUMBER()OVER (ORDER BY empID) as empnum , fName, filePath from Employee where EmpID='KF14170';
I might add the format of the file is empID plus the filename:
Example: KF14170Evidence1, KF14170Evidence2.

For those who want to know the root of my question without any of the detail:
I want to know if there is any recommended way to detect and remove potential malware from files uploaded to SQL 2005 Reporting Services via the Report Manager.
Here's a general description of our setup and challenge:
We have a Windows 2003/SQL 2005 Enterprise Server as the reporting database server and another server running Windows 2003/IIS 6.0/ColdFusion MX7/SQL 2005 Reporting Services as the web server. The Report Server is only used internally, but has a potential user community of approximately 150,000. The actual community of users who would have access to the Report Manager would be much smaller.
In our environment, we have no way of ensuring that virus scans are being performed at all of the clients, so we need a way to make sure that files uploaded through Report Manager are all being checked as they are coming in to the Report Server.
Here's what we've tried so far:
We downloaded the Eicar A/V test file and verified that Report Manager has no problem accepting it as an uploaded files by default. The servers are running Norton AntiVirus Corporate 10.2 with the latest definitions and it did not detect the virus as it was being loaded in to the database.
Next, I setup Microsoft ISA 2006 in reverse proxy mode with Kaspersky's Antivirus for ISA. Kaspersky does not prevent a client from uploading the test file to Report Manager, but it does prevent the user from downloading it, so it seems that it only works with HTTP get operations and ignores HTTP put operations.
I have had Watchguard come in with a Firebox (an appliance that they claimed could A/V scan files), but it provided similar results. Files uploaded to Report Manager were ignored, but infected files downloaded were blocked.
I have BlueCoat, TrendMicro, and CheckPoint all on tap to come in and see if they can fare any better, but I am not holding much hope for this.
I know that SharePoint has an API that virus scanners can use (VSAPI) for scanning binaries stored within its SQL database. Is there anything similar for SQL Reporting Services? Is there any other way of preventing these files from entering the application?
Thanks for reading and any responses. I am happy to provide more details if it would be helpful.

I am trying to save an uploaded picture filepath to a sql database record. The record that the filepath will be saved to will be the record determined by the logged in userid. I get an error stating Object not set to an instance of an object. This is my code for when the upload button is hitProtected Sub uploadbutton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uploadbutton.Click
If UploadTest.HasFile = False Then
' No file uploaded!
UploadDetails.Text = "Please first select a file to upload..."
Else
' Display the uploaded file's detailsUploadDetails.Text = String.Format( _
"Uploaded file: {0}<br />" & _"File size (in bytes): {1:N0}<br />" & _"Content-type: {2}", _
UploadTest.FileName, _
UploadTest.FileBytes.Length, _
UploadTest.PostedFile.ContentType)
' Save the fileDim filePath As String = Server.MapPath("~/ProfilePictures/" & UploadTest.FileName)
UploadTest.SaveAs(filePath)Dim datasources1 As New SqlDataSourcedatasources1.ConnectionString = ConfigurationManager.ConnectionStrings("aspnetdb_connection").ToString()
datasources1.UpdateCommandType = SqlDataSourceCommandType.Text
Dim myUserID As String = Membership.GetUser().ProviderUserKey.ToStringdatasources1.UpdateParameters("userid").DefaultValue = myUserID
datasources1.UpdateCommand = "UPDATE into profile_details (pic) VALUES (@filepath) WHERE ([UserId] = @UserId)"
End If
End Sub
Any ideas on what i need to do to fix this?

I am almost done with a simple page to have a user select a file (using the FileUpload object), give it a short description and associate it with an item from a listbox. Thensave these pieces of data to a new row in a SQL DB.
My issue...
The SQLSmd.ExecuteNonQuery FAILS...
I have got all the fields able to connect and almost save... but for the actual "document" field errors out. The user can select any type of file (image, word, excel, Powerpoint, etc) for storage into the DB. I am not storing a referance to a file or the path to a file but the actual file in SQL.In the DB I have the field (Document) set to a type of VarBinary(8000) in the table. Here is thethe corrisponding code in my app...
Dim bArray As Byte...bArray = FileUpload1.PostedFile.InputStream.ReadByte()... SQLCmd.Parameters.Add("@Document", Data.SqlDbType.VarBinary, 8000).Value = bArray...iReturn = SQLCmd.ExecuteNonQuery()
ERRORThe first section of the stact trace...
[InvalidCastException: Invalid cast from 'System.Byte' to 'System.Byte[]'.] System.Convert.DefaultToType(IConvertible value, Type targetType, IFormatProvider provider) +867 System.Byte.System.IConvertible.ToType(Type type, IFormatProvider provider) +37 System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) +408 System.Data.SqlClient.SqlParameter.CoerceValue(Object value, MetaType destinationType) +896

I recently set up a SQL 2012 FCI with a NetApp fileshare to store the data files. The install worked just fine, but I can't run an integrity check for any of my databases. Whenever I try, I get these error messages:
Msg 1823, Level 16, State 2, Line 1
A database snapshot cannot be created because it failed to start.
Msg 1823, Level 16, State 8, Line 1
A database snapshot cannot be created because it failed to start.
Msg 5120, Level 16, State 104, Line 1
Unable to open the physical file "path-to-fileshareMSSQL11.MSSQLSERVERMSSQLDATAmodel.mdf:MSSQL_DBCC12". Operating system error 1: "1(Incorrect function.)".
Msg 7928, Level 16, State 1, Line 1
The database snapshot for online checks could not be created. Either the reason is given in a previous error or one of the underlying volumes does not support sparse files or alternate streams. Attempting to get exclusive access to run checks offline.The error message suggests SQL had a problem creating the snapshot, but I checked through some NetApp documentation for configuring SMB 3.0 for SQL.

I tried samples of FileTable in SQL Server 2012 to store files in database. I have following questions.
1. When I right click on FileTable, and say Explore File Table Directory, I was taken to a directory. But if I search the same directory in my server/machine, the directory is not available.
2. Can I use some external server/disk as a directory for FileTable?
3. How easy is to use FileTables using .Net web applications?

This is an upload from foxpro to SQL Server.
My package loads about a million records and reject about 5,000 records. The rejected records are routed to a foxpro table.
Is there a way to find out why the records were rejected and sent to the error table?. I need to determine the reason so I can fix the records and try to upload them again.
Any help is appreciated.
Thanks

I am trying to send a parameter to an uploaded report, It's default path is:
http://server/Reports/Pages/Report.aspx?ItemPath=%2fNavsion%2fNavision+PO+Report
I tried:
http://server/Reports/Pages/Report.aspx?ItemPath=%2fNavsion%2fNavision+PO+Report&rs:Command=Render&PONo=15818
It did not run and when I manually added the parameter it changed to:
http://server/Reports/Pages/Report.aspx?ItemPath=%2fNavsion%2fNavision+PO+Report&rs%3aCommand=Render&PONo=15818
I also tried to change the properties parameters settings has default unchecked and prompt unchecked
do I need to place the file in a folder on the server instead of uplading it?

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 opened an account in [URL] and taken the 60 days trial for power bi pro. I've developed power pivot and generated power views in share point 2013. But, I'm new to Power BI desktop. I have created a report in power BI desktop and published to [URL]. Also, I have uploaded an excel file directly to [URL] and created the report from the workspace available there itself and pinned the report to dashboard also. Everything is fine till this. But, I need to refresh the file which I have uploaded. I have some dummy data in excel sheet.
ZipCode State ZipName
2345 AA AA
456 BB BB
6787 CC CC
This has been created as a table and then added to data model. So, power pivot has been created for the same. Then I have uploaded this file to [URL] site. But, I'm getting an error message while trying to schedule refresh for the same.
"You cannot schedule refresh for this dataset because it does not contain data model connections. You cannot schedule refresh on worksheet connections or linked tables. To schedule refresh the data must be loaded into the data model."
How can I create a data model connection? How can I schedule refresh for an excel file like this?

Hi everyone,
I'm just using TEXTBOX control to save data into my DB. My question is, if I have multiple lines of sentences, it does not store as what it looks like. For example;
Hello, Mike
It stores into the database as "Hello, Mike" and if I read from the database, it does not have seperate lines and shows it like this;
Hello, Mike
How can I store the contents into database and make the contents as original? (Sorry for the poor English, but I hope you understand it.)
