no record is added

Did you mean to mark this resolved? You still having the problem?

I fix this problem, she be Is that ID > max.
Remember i task you how me raise record? I concocted decision –>

function my_dsfg() {
	$currents_users = wp_get_current_user();
	global $wpdb;
	$d = getdate();
	$get_var_time = $wpdb->get_var("SELECT comparison FROM wp_participants_database WHERE id_private = '$currents_users->id' "); // получает больше на 1 час comparison(1)
	$get_current_time = $wpdb->get_var("SELECT tametame FROM wp_participants_database WHERE id_private = '$currents_users->id' ");  // получает текущее время  tametame(2)
	$get_max_id = $wpdb->get_var("SELECT max(id) FROM wp_participants_database "); // получает самый большой ид	
	$wpdb->query(" UPDATE wp_participants_database SET tametame = NOW() + INTERVAL 59 MINUTE WHERE id_private = '$currents_users->id' ");  // = поле даёт текущее время
	$wpdb->query(" UPDATE wp_participants_database SET id = id + '$get_max_id' WHERE id_private = '$currents_users->id' AND comparison <= NOW() "); // даёт ид + ид МАх когда время + 1 < текущего
    $hfuftm = $wpdb->query(" UPDATE wp_participants_database SET comparison = NOW() + INTERVAL 1 HOUR WHERE id_private = '$currents_users->id' "); // даёт текущее + 1	
}	

function my_fdffg() {	
	$currents_users = wp_get_current_user();
    global $wpdb; 
    $injoi = $wpdb->query(" UPDATE wp_participants_database SET toto = 60 WHERE id_private = '$currents_users->id' AND toto = 0 ");
	$plot = $wpdb->get_var("SELECT min(toto) FROM wp_participants_database WHERE id_private = '$currents_users->id' ");	
	 echo "Все ваши записи обновлены! Следущее обновление доступно через $plot минут";
}

function my_taming() {

    global $wpdb; 
	$plots = $wpdb->get_var("SELECT toto FROM wp_participants_database");	
	if($plots <= 0) 
	{
	$wpdb->query(" UPDATE wp_participants_database SET toto = 1");	
	}
}
my_taming();

function cron_qwerttrewq_ce2a6dea() {
	$currents_users = wp_get_current_user();
    global $wpdb; 
	$yuy = $wpdb->query(" UPDATE wp_participants_database SET toto = toto - 1");

}

add_action( 'qwerttrewq', 'cron_qwerttrewq_ce2a6dea', 10, 0 );

function cron_downidd_3b05c61a() {
  	$currents_users = wp_get_current_user();
    global $wpdb; 
	$sda = $wpdb->query(" UPDATE wp_participants_database SET id = id / 2");

}

add_action( 'downidd', 'cron_downidd_3b05c61a', 10, 0 );

I dropped the code in case anyone needed it.
