Being a very novice SQL Server administrator, I need to ask the experts a question.
How do I go about moving a database from 1 drive to another? The source drive (C is local to the server, but the target drive (E is on a Storage Area Network (SAN), although it is still a local drive for the server. I want to move the database from C: to E:. Can someone provide me with instructions?
Thanks,
Rick
How do you compare SAN drive vs local drive on a 32 bit server?
Is it good idea to move my DB files to a SAN instead of local?

I used upload image feature and below is the code that I used. The image is stored in a folder. I want to save the image in sql database. I create the database which is “database�, and I create a table which is “user�. User table has auto “id� field and “image� field. I want to save the image in the image field. I need your help to do the other codes.
I am using asp.net with VB
This is what I did so far:
============================
Partial Class upload
Inherits System.Web.UI.Page
Dim strFileName As String
Protected Sub btnupload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnupload.Click
UploadImage()
End Sub
Sub UploadImage()
If Not (fileupload1.PostedFile Is Nothing) Then 'Check to make sure we actually have a file to upload
Dim strLongFilePath As String = fileupload1.PostedFile.FileName
Dim intFileNameLength As Integer = InStr(1, StrReverse(strLongFilePath), "")
strFileName = Mid(strLongFilePath, (Len(strLongFilePath) - intFileNameLength) + 2)
Select Case fileupload1.PostedFile.ContentType
Case "image/pjpeg", "image/jpeg" 'Make sure we are getting a valid JPG image
FileUpload1.PostedFile.SaveAs(Server.MapPath(" estimages") & strFileName)
lbstatus.Text = strFileName & " was uploaded successfully to: " & Server.MapPath(" estimages") & strFileName
Case Else

Please help me... How can i upload image into my sql database in a basic way... thanks....
View 6 Replies View RelatedI am creating a update, delete, edit form for my web database. The form works in everyway except that when I try to upload the image to the database it does not go into the database. (I know the pros and cons of storing images in a database. In this instance it is what makes the most since. )
I have to admit I have never uploaded anything to my server or database before (other than plain text). I have read through several articles and have a high level of understanding.
I found an example on a website that used the OnInserting/OnUpdating command. But it is not working. I tried to find another similar example so that I could better understand it and try to fix what must be wrong. I can't find a similar example.
I am posting the code I have below. Any help would be most appreciated.

Hi all, I dont know if anyone here can help me...I am using ASP.NEt with VB.Net and SQL Sever...What I am trying to do is create a system whereby it allows users to upload images into sql server, and thereon later retireve this image.I used a book called The Ultimate VB.Net and ASP.Net Code Book, and it basically gave me the code below to upload and retrieve images. I seem to have managed to allow the uploading of images, with them being stored as <byte> in my database, thought I have no idea how to retrieve them...Does anyone have any ideas???Here is the code I followed.. :"Storing Uploaded Files in Your Database First, a few tips on storing files inside your SQL Server database.For convenience, you’ll really need to store at least three bits of information about your file to get it out in the same shape as you put it in. I’d suggest “data� (a field that will hold your actual file as a byte array, data type “image�), “type� (a field to hold details of the type of file it is, data type “varchar�), and “length� (a field to hold the length in bytes of your file, data type “int�). I’d also recommend “downloadName�, a field to hold the name that the file had when it was uploaded, data type “varchar�. This helps suggest a name should the file be downloaded again via the Web.The problem you have is translating the information from the File Field control into an acceptable format for your database. For a start, you need to get your file into a byte array to store it in an image field. You also need to extract the file type, length, and the download name. Once you have this, set your fields to these values using regular ADO.NET code.So, how do you get this information? It’s simple: just use the following ready-to-run code snippets, passing in your File Field control as an argument. Each function will return just the information you want to feed straight into your database, from a byte array for the image field to a string for the file type.Public Function GetByteArrayFromFileField( _ ByVal FileField As System.Web.UI.HtmlControls.HtmlInputFile) _ As Byte() ' Returns a byte array from the passed ' file field controls file Dim intFileLength As Integer, bytData() As Byte Dim objStream As System.IO.Stream If FileFieldSelected(FileField) Then intFileLength = FileField.PostedFile.ContentLength ReDim bytData(intFileLength) objStream = FileField.PostedFile.InputStream objStream.Read(bytData, 0, intFileLength) Return bytData End If End Function Public Function FileFieldType(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As String ' Returns the type of the posted file If Not FileField.PostedFile Is Nothing Then _ Return FileField.PostedFile.ContentType End Function Public Function FileFieldLength(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As Integer ' Returns the length of the posted file If Not FileField.PostedFile Is Nothing Then _ Return FileField.PostedFile.ContentLength End Function Public Function FileFieldFilename(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As String ' Returns the core filename of the posted file If Not FileField.PostedFile Is Nothing Then _ Return Replace(FileField.PostedFile.FileName, _ StrReverse(Mid(StrReverse(FileField.PostedFile.FileName), _ InStr(1, StrReverse(FileField.PostedFile.FileName), ""))), "") End Function Sorted! One question remains, however. Once you’ve got a file inside a database, how do you serve it back up to a user? First, get the data back out of SQL Server using regular ADO.NET code. After that? Well, here’s a handy function that’ll do all the hard work for you. Simply pass the data from your table fields and hey presto:Public Sub DeliverFile(ByVal Page As System.Web.UI.Page, _ ByVal Data() As Byte, ByVal Type As String, _ ByVal Length As Integer, _ Optional ByVal DownloadFileName As String = "") ' Delivers a file, such as an image or PDF file, ' back through the Response object ' Sample usage from within an ASP.NET page: ' - DeliverFile(Me, bytFile(), strType, intLength, "MyImage.bmp") With Page.Response .Clear() .ContentType = Type If DownloadFileName <> "" Then Page.Response.AddHeader("content-disposition", _ "filename=" & DownloadFileName) End If .OutputStream.Write(Data, 0, Length) .End() End With End Sub Simply pass your byte array, file type, and length, and it’ll send it straight down to your surfer. If it’s an image, it’ll be displayed in the browser window. If it’s a regular file, you’ll be prompted for download.If it’s made available for download, this function also allows you to specify a suggested download file name, a technique that many ASP.NET developers spend weeks trying to figure out. Easy! Working with Uploaded Images Whether you’re building the simplest of photo album Web sites or a fully fledged content management system, the ability to work with uploaded images is a vital one, and with ASP.NET, it’s a real doddle.The following code snippet shows you how, by example. It takes a data stream from the File Field control and converts it into an image object, adding simple error handling should the uploaded file not actually be an image. The code then uses this image object to extract a few core details about the file, from its dimensions to file type:' Get data into image format Dim objStream As System.IO.Stream = _ MyFileField.PostedFile.InputStream Dim objImage As System.Drawing.Image Try ' Get the image stream objImage = System.Drawing.Image.FromStream(objStream) Catch ' This is not an image, exit the method (presuming code is in one!) Exit Sub End Try ' Filename Dim strOriginalFilename As String = MyFileField.PostedFile.FileName ' Type of image Dim strImageType If objImage.RawFormat.Equals(objImage.RawFormat.Gif) Then strImageType = "This is a GIF image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Bmp) Then strImageType = "This is a Bitmap image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Jpeg) Then strImageType = "This is a JPEG image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Icon) Then strImageType = "This is an icon file" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Tiff) Then strImageType = "This is a TIFF file" Else strImageType = "Other" End If ' Dimensions Dim strDimensions As String strDimensions = "Width in pixels: " & objImage.Width & _ ", Height in pixels: " & objImage.Height ' Send raw output to browser Response.Clear() Response.Write(strOriginalFilename & "<p>" & strImageType & _ "<p>" & strDimensions) Response.End() "For some reason the retrieval code isnt working for me..Can anyone provide any help? even if it means using another method?

Hi,
SQL Server 2008 on its way. 2005 should be standard. But sometimes you have SQL Server 2000.
How can I upload an image into the SQL Server 2000 with an T-SQL Statement?
In SQL Server 2005 I would write something like this:
Code Snippet
INSERT INTO ReportingImages
(Name, Img)
SELECT 'UploadTest',
BulkColumn FROM OPENROWSET(
Bulk 'C:ds9.png', SINGLE_BLOB) AS BLOB
That doesnt work under 2000.
What about uploading to the SQL Server 2000 and an Image-Datatype?
Is it even possible in T-SQL without a Web-Service or C#/VB-written tool?
-------------------------------
Update: Thank you all for your answers. We'll use a tool then.
I am using FileUpload method in tools box and i want to store the uploaded image into database.
but when debuging it will shows an error like: Operand type clash: sql_variant is incompatible with image
this is the code for "upload" button.Protected Sub uploadbtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uploadbtn.Click
If FileUpload1.HasFile Then
TryFileUpload1.SaveAs("C: emp" & FileUpload1.FileName)
Label1.Text = "File name: " & FileUpload1.PostedFile.FileName & "<br>" & "File Size: " & FileUpload1.PostedFile.ContentLength & "kb<br>" & "Content Type: " & FileUpload1.PostedFile.ContentTypeCatch ex As Exception
Label1.Text = "ERROR: " & ex.Message.ToString
End Try
Else
Label1.Text = "You have not specified a file"
End If
Try
SqlDataSource1.Insert()
Label2.Text = "picture is saved"Catch ex As Exception
Label2.Text = ex.Message.ToString
End Try
End Sub
I am using the image datatype to upload files onto SQL SErver 2000. My
problem is that it seems as though the database is only accepting files
of size 65Kb or less.
What is the best way of resolving this problem?
I am trying to save an uploaded image and its associated info to sql server database using a stored procedure but keep getting trouble. When trying to save, the RowAffected always return -1. but when i debug it, I dont' see problem both from stored procedure server
explore and codebehind. it looks to me every input param contains correct value(such as the uploaded image file name, contentType and etc). well, for the imgbin its input param value returns something like "byte[] imgbin={Length=516}". Below is my code, could anyone help to point out what did I do wrong?
Thank you.

Hi all!
I am a newbie with SQL Server and need some advice. I have developed a small database with Microsoft SQL Server 2005 Express on my local computer. I am using it in conjunction with SQL Server Management Studio Express. Now I want to upload it to an online web host. What is the best way to upload? Do I use replication or some other means? Can I do so with Management Studio Express? My web host has an administration Console which does not seem to work with the database, and their support service is very slow. So I do not know what to do.
Any advice would be helpful.
Thank you

Hello,
I need help with the setup of my sql server express 2005 and more specifically, with the location of the database files. Normally, database files are located on the c: drive. In my situation, being in a high school environnement, I need to have the database files on the network drive ... lets call it g:drive. The reason why it cannot be on c:drive is because this drive is protected using DeepFreeze. Now, I was able to change the location of the new drive as I went into the properties window of the sql server instance but when I try to create this new database, sql gives me grief ;-|
I am from the group of people that thinks that to anything, there is a solution and am hoping that to this problem, there is hope of a solution.
Can anyone help?
Thank you

I've been working with SQL Server for a few years now and I've had quite a few cases where users cannot backup SQL to a network location or external hard drive. Why can SQL not do this? Is it some limitation of the speeds at which SQL needs to backup the information and the external hard drives/network drives do not meet the requirements?
I'm trying to build a new cluster with SQL Server 2K Enterprise onWindows 2003 server. When I run the install, I tell it to put theprogram files on the D: (local) drive and the data/log files on shareddrives. However, after the installation is complete, almost all thefiles go in the C: drive in program filesMicrosoft SQL Server, ratherthan the D: drive (it does create a few files on D:). We've experiencedthis on more than one server build.Anyone know any way around this?Post answers publicly, please, or email tosteven.wechsler(at)mtvstaff.com (the posting email address is hosed).Thanks,Steve

I have created an sql server 2005 maintenance plan for a daily backup. The plan has two 'Back up database task' i.e. one backup on the local drive while the second on a network drive. When the plan is executed, a backup is created on the local drive but not on the network drive. If i check the log, it says "Access Denied" whereas i have full access to the network drive with complete permissions to read, write and delete.
Can anyone help me understand how to take a backup on both a local and network drive at the same time using a maintenance plan ? I shall be obliged...
Regards...
We are seeing very high Average Disk Queue Length numbers in one of our clusters (both nodes of the cluster are Virtual, but have their own dedicated virtual environments). Our main data drive also houses TempDB, which I would like to move.
Each node in the Active/Passive cluster are running Windows Server 2012 Standard 64bit and SQL Server 2012 Enterprise 64bit. There is a separate drive for Log files and data files.
The data files also have TempDB on them as previously mentioned. I am reading that you can set up a local disk on each node of the cluster, with the same drive letter and path and then move tempdb as you would with a stand alone SQL Server.
I am having a problem accessing my local A: drive, using the bulk insert command. The actual sql server pc thinks I am accessing its sql server's A: and not my local a: drive. I am trying to read in a simple CSV delimited ascii file into a sql table. Wow what a nightmare just to read a simple ascii file into a table. Unfortunatley I am writing a program in VB.net for an operator to import ascii data from floppy diskettes.
I am using this command below: The command works fine but I have to go to the actual server and put the floppy disk in over there. I want the operator to be able to use there own A: or any location drive for that matter. Sql server over the network is not allowing us to access any local drive to import this data. I get an error 21 because the sql server does not have the floppy in its drive. It seems like some kind of security issue, but I am not sure. Any information would be most appreciated in this matter. Thanks in advance.

sample code below:
BULK INSERT Master.dbo.imVBMbAddress
FROM 'a:mbAddressPipes.txt'
WITH (FORMATFILE = 'a:importdatambaddress.fmt',
FIRSTROW=2);
I have a Windows Internal Database (installed by SharePoint WSS 3.0) and SQL Server Management Studio Express installed on W2K3 Std server. The server has local hard disk drive C, E, F & G. However SQL Server Management Studio Express only recognize C and E drive, for example in the set default database location or in attach database file dialog window only C & E drive are available. Anyone knows why and how to fix the problem?
Thanks

This server has a Raid 5 Disk Array partitioned into three Logic Drives C:, S:, L:. Not sure, why the server was configured this way. If I attach the database with the data and log files on the same logical drive, the DB attaches successfully. When I try to put the data and log files on separate logical drives, it fails. Issue seems to be with the drive partitioning. Any Ideas?
We are attempting to restore one of our databases from a backup that went to a local drive on the server.
We see the backupset in the list but receive an error that it is not available when we try to use it. When we try to restore from device and select the files the drive letter is not available. When we attempt to enter the path to the file it can't locate it. We don't have space on our SAN to copy the backup there and we can't add the local drive to the cluster resources.
Is there a way to get this backup done?
I would like to use bcp and transfer image data from MS-SQL Server 6.5 to MS SQL Server 2005.
1. Can I use bcp successfully? if so should I mention any option to copy the BLOB?
2. Is there any reliable method to move tables with BLOBs
