                {
                    connection.Open();
                    using(SqlDataAdapter adapter = newSqlDataAdapter("select * from adalog where [message] like ‘test%’", connection))
                    {
                        int rowsAffected = adapter.Fill(dataTable);
                    }
                }
                if(dataTable.Rows.Count > 0)
                    result = true;
            }

                connection.Open();
                using(SqlCommand command = newSqlCommand("truncate table adalog", connection))
