Writing a Memo field to an Access DB with OleDB

Hello,

I have big problem on updating an Access Memo field with OleDb. While the
InsertCommand works, then UpdateCommand raises an exception: Syntaxerror in
UPDATE-Statement. I tryed various work arounds (the last 3 days) with and
without the CommandBuilder with allways the same result.

The last attempt was:

Public Function WriteMemoToAccess(ByVal Pars As String) As Boolean
'Parameters is the ColumnName of the Access Memo field
Dim AccessCommand As New OleDb.OleDbCommand("UPDATE DocH SET Parameters=?
WHERE IdNum = 1")

Dim QueryParameter As New OleDb.OleDbParameter("@Parameters", _
OleDb.OleDbType.LongVarWChar, Len(Pars), ParameterDirection.Input,
True, _
Nothing, Nothing, Nothing, DataRowVersion.Current, Pars)

AccessCommand.Parameters.Add(QueryParameter)
AccessCommand.Connection = Me.Connection
Me.Connection.Open()
Try
AccessCommand.ExecuteNonQuery()
WriteMemoToAccess = True
Catch ex As Exception
End Try
Me.Connection.Close()
End Function

Is there a way to do this??

Best regards

Is the columnname you want to update really called Parameters?

If so, Parameters is probably a reserved word. Try wrapping it in [ ] or
even renaming the column and associated references.

Yes, Parameters is a keyword in OleDb. I found this 10 min ago.
But I find no work around in programm code. I need to change the name in the
Access db

Thank you very much.

As Jim mentioned you can enclose it within brackets: [Parameters]

Many Thanks,

but if I enclose them in the SelectCommand why the CommandBuilder does not
enclose them in the other commands too?

Because the CommandBuilder was not designed to handle this issue. You have to make the modification
manually.
