パラメータを使用して OleDb テーブルを効果的に更新するにはどうすればよいですか?

using (OleDbConnection conn = new OleDbConnection(connString))
{
    conn.Open();
    OleDbCommand cmd = conn.CreateCommand();

    // Create OleDbParameters for each field
    OleDbParameter paramMName = new OleDbParameter("@MName", customer.MName);
    OleDbParameter paramDesc = new OleDbParameter("@Desc", customer.Desc);

    // Add parameters to command object
    cmd.Parameters.Add(paramMName);
    cmd.Parameters.Add(paramDesc);

    // Construct SQL query with parameter placeholders
    cmd.CommandText = "UPDATE Master_Accounts SET M_Name=@MName, Desc=@Desc WHERE LM_code=@LM_code";

    // Execute update using parameters
    cmd.ExecuteNonQuery();
}
