access sql and the LIKE keyword [duplicate]

Question

I am working on an addin for Visio using Access as a backend database. In one of my forms I am filling a datagridview with parts from a table. In this DGV I wish to include only parts of type "connector" and also filter out connector parts which have the word "banana" (banana connectors) in the description. The line of sql I came up with seemed simple enough, when I execute it in a query window within Access it works as expected. However, when I execute the exact statement within the context of my addin, it still returns the banana connectors! Can anyone tell me what the difference is? Below is the code from my addin. Thanks for any tips

Using con As New OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & VE_docPath & VE_currentProject & ".accdb;Persist Security Info=True")
            Using cmd As New OleDb.OleDbCommand("", con)
                Try
                    sql = "SELECT PartDefID, PartNumber, PartNumberAlt, PartDescription, ShellType, ElementCount, TerminalCount, KitNumber FROM PartDefinitions WHERE PartClass = 1 AND (PartDescription NOT LIKE '*banana*')"
                    cmd.CommandText = sql
                    cmd.CommandType = CommandType.Text
                    cmd.Connection = con
                    con.Open()
                    Dim daGet As New OleDbDataAdapter()
                    daGet.SelectCommand = cmd
                    daGet.Fill(TableConnector)
                    Me.PartDefDataGridView.DataSource = TableConnector
                    If Me.PartDefDataGridView.RowCount > 0 Then
                        Me.PartDefDataGridView.Columns("PartDefID").Visible = False 'hide this column in the DGV
                        Me.PartDefDataGridView.ClearSelection()
                        Me.PartDefDataGridView.Rows(0).Selected = True
                    End If
                Catch SqlError As System.Data.SqlTypes.SqlTypeException
                    MsgBox(SqlError.Message, MsgBoxStyle.SystemModal, "Error")
                Catch ex As Exception
                    MsgBox(ex.Message, MsgBoxStyle.SystemModal, "Error")
                End Try
            End Using
        End Using
