It's working like that:


 

$servername = "localhost";
$username = "xxx";
$password = "xxx";
$dbname = "energy";

date_default_timezone_set("Europe/Sofia");

$h = date('H');
$m = date('i');
$month = date('n');
//$year = date('Y');

$conn = mysqli_connect($dbservername, $dbusername, $dbpassword, $dbname);
$api_key_value = "tPmAT5Ab3j7F9";
$api_key =  $voltage = $current =  $frequency = $power = $energy  =  "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {

    $api_key = ($_POST["api_key"]);
    if($api_key == $api_key_value) {

        $voltage = ($_POST["voltage"]);
        $current = ($_POST["current"]);
        $frequency = ($_POST["frequency"]);
        $power = ($_POST["power"]);
        $energy = ($_POST["energy"]);

        // Create connection
        $conn = new mysqli($servername, $username, $password, $dbname);

        // Check connection
        if ($conn->connect_error) {
            die("Connection failed: " . $conn->connect_error);
        }

        switch($month) {

            case 12:{

                if   (($h >= 06 && $m >=00 )  && ($h <= 21 && $m <=59))   {                  
                    $sql = "INSERT INTO energy_home_January (voltage,current,frequency,power,energy)
                           VALUES ('" . $voltage . "', '" . $current . "', '" . $frequency . "', '" . $power . "', '" . $energy . "')";
               }
               else{
                    $sql = "INSERT INTO energy_home_January_night (voltage,current,frequency,power,energy)
                            VALUES ('" . $voltage . "', '" . $current . "', '" . $frequency . "', '" . $power . "', '" . $energy . "')";
                   }  
           }
           break;

But I want to use this.  

INSERT INTO test3(
    id,
    voltage,
    current,
    frequency,
    power,
    energy,
    reading_time,
    resultat
)

SELECT
    id,
    voltage,
    current,
    frequency,
    power,
    energy,
    reading_time,
    energy - LAG(energy) OVER(ORDER BY id) AS temp

FROM
    energy_home_november
