Blob: INSERT a file in SQL Server


M

Michael Maes

Hello,

I'm trying to INSERT all kind of files in a SQL Server 2000 Table.
These files are e-mail attachments (.PDF, .XLS, .DOC, ....).

Using the code below, returns an IConvertible error.
The DataType of the field is 'Text'. Should this be 'Image'?

What am I missing?

Michael

Dim sqlCONN As New SqlConnection(global.sdc)

Dim scmd As New SqlCommand("UPDATE tblEmailAttachments SET
[email protected] WHERE emailID = " & emailID & " AND fileName = " &
fileName, sqlCONN)

Dim fs As New System.IO.FileStream(SourceFilePath, IO.FileMode.Open,
IO.FileAccess.Read)

Dim b(fs.Length() - 1) As Byte

fs.Read(b, 0, b.Length)

fs.Close()

Dim P As New SqlParameter("@attachment", SqlDbType.Text, b.Length,
ParameterDirection.Input, False, 0, 0, Nothing, DataRowVersion.Current, b)

scmd.Parameters.Add(P)

sqlCONN.Open()

scmd.ExecuteNonQuery()

sqlCONN.Close()
