Storing Microsoft Word 97 documents in SQL Server column

I have this database with a table which has the the following but I have no way to decypher it

DATA,        TYPE,            FILE TYPE, SIZE,  DOC TYPE
0x15234324 , Word.Document.8 ,DOC,       19968, WORD.DOCUMENT.8

The field seems to contain a word document stored in a SQL Server IMAGE column

Has anyone come across this before or a way to extract this data in a readable format?

So far I have tried using PHP to extract the file and write it to a word document but not had much luck.

UPDATE: I now have Visual Studio Express and would like a way to extract this data and save to a word document

UPDATE2: This is what I have in VB sofar

Public Class Form1

    Private Shared Function RetrieveFile(ByVal filename As String) As Byte()

        command.Parameters.AddWithValue("test", filename)
        connection.Open()
        Dim reader As SqlDataReader = command.ExecuteReader(System.Data.CommandBehavior.SequentialAccess)
        reader.Read()
        Dim memory As New MemoryStream()
        Dim startIndex As Long = 0
        Const ChunkSize As Integer = 256
        While True
            Dim buffer As Byte() = New Byte(ChunkSize - 1) {}
            Dim retrievedBytes As Long = reader.GetBytes(1, startIndex, buffer, 0, ChunkSize)
            memory.Write(buffer, 0, CInt(retrievedBytes))
            startIndex += retrievedBytes
            If retrievedBytes <> ChunkSize Then

            End If
        End While
        connection.Close()
        Dim data As Byte() = memory.ToArray()
        memory.Dispose()

I wrote a VBS script to pull data out of sharepoint blobs a while back, here's a generic version of it:

Const adOpenKeyset                  = 1
Const adLockOptimistic              = 3
Const adTypeBinary                  = 1
Const adSaveCreateOverWrite         = 2

strSQLServer = "YOURSERVER"
strSQLDatabase = "YOURDB"
strRecordID = "123"
strTempFileName = "c:\output.doc"

Set objConn = CreateObject("ADODB.Connection")
Set objRS = CreateObject("ADODB.RecordSet")
Set objStream = CreateObject("ADODB.Stream")

objConn.Open "Provider=SQLOLEDB;data Source=" & strSQLServer & ";Initial Catalog=" & strSQLDatabase & "; Trusted_Connection=yes;"
objRS.Open "Select * from AllDocStreams WHERE ID='" & strRecordID & "'", objConn, adOpenKeyset, adLockOptimistic

objStream.Type = adTypeBinary
objStream.Open
objStream.Write objRS.Fields("Content").Value
objStream.SaveToFile strTempFileName, adSaveCreateOverWrite

objRS.Close
objConn.Close


C# code:

connection.Open();
SqlCommand command1 = new SqlCommand("select DATA from TABLE where ...", connection);
byte[] img = (byte[])command1.ExecuteScalar();
File.WriteAllBytes("your_path/word.doc", img);

That should be the logic. Write something similar in any language you know. It shouldn't be hard in PHP or whatever you are using.


take a look at this thread.

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=101754

The guy does it using the SCRIPTING.FILESYSTEMOBJECT to extract the contents from an IMAGE column and write it to a file.

read down through the comments.


Try something like this, replace the "some" values with your own:

declare @doc varbinary(max), @ObjectToken int

select @doc = (select data from yourTable were someID = @idThatYouWant)

set @FileName = '\someFolder\' + 'someFilename.doc'

print 'Processing: ' + isnull(@FileName, 'null')

exec sp_oacreate 'ADODB.Stream', @objecttoken output
exec sp_oasetproperty @objecttoken, 'type', 1
exec sp_oamethod @objecttoken, 'open'
exec sp_oamethod @objecttoken, 'write', null, @doc
exec sp_oamethod @objecttoken, 'savetofile', null, @FileName, 2
exec sp_oamethod @objecttoken, 'close'
exec sp_oadestroy @objecttoken


I think you will get an IndexOutOfRangeException in the following line of your code:

 Dim retrievedBytes As Long = reader.GetBytes(1, startIndex, buffer, 0, ChunkSize)

because the index of the first param is 0 not 1

anyway I suggest you use a method like the one Klark has suggested, which is simpler and more readable.
