Put a type in a blob in sqlite?

Dim ra As RandomAccessFile
   ra.Initialize(File.DirDefaultExternal, "temp1.dat", False)
   ra.WriteObject(AllServiceOperations, False, 0)
   ra.Close
   Dim os1 As OutputStream
   Dim is1 As InputStream
   is1 = File.OpenInput(File.DirDefaultExternal, "temp1.dat")
   os1.InitializeToBytesArray(1000)
   File.Copy2(is1, os1)
   Dim bytes1() As Byte
   bytes1 = os1.ToBytesArray
   'ra.ReadBytes(bytes1, 0, bytes1.Length, 0)
   sql1.ExecNonQuery2("UPDATE tblJobs SET all_operations=? WHERE device_job_id=?", Array As Object(bytes1, device_job_id))
   File.Delete(File.DirDefaultExternal, "temp1.dat") ' deleting the temp file.

Dim output1() As Byte
      If sql1.IsInitialized = False Then sql1.Initialize(File.DirDefaultExternal, "jobs.db", True)
      output1 = sql1.ExecQuerySingleResult2("SELECT all_operations FROM tblJobs WHERE device_job_id=?", Array As String(device_job_id))
      Dim is1 As InputStream
      is1.InitializeFromBytesArray(output1, 0, output1.Length)
      Dim os1 As OutputStream
      os1.InitializeToBytesArray(1000)
      File.Copy2(is1, os1)
      Dim ra As RandomAccessFile
