    mysqli::next_result

    mysqli_next_result

    (PHP 5, PHP 7, PHP 8)

    mysqli::next_result -- mysqli_next_result — Prepare next result from multi_query

    Açıklama

    Nesne yönelimli kullanım

    public mysqli::next_result(): bool

    Yordamsal kullanım

    mysqli_next_result(mysqli $mysql): bool

    Prepares next result set from a previous call to mysqli_multi_query() which can be retrieved by mysqli_store_result() or mysqli_use_result().

    Bağımsız Değişkenler

    bağlantı

    Sadece yordamsal tarz: mysqli_connect() veya mysqli_init() işlevinden dönen bir mysqli nesnesi.

    Dönen Değerler

    Başarı durumunda true, başarısızlık durumunda false döner. Also returns false if the next statement resulted in an error, unlike mysqli_more_results().

    Hatalar/İstisnalar

    Eğer mysqli hata bildirimi etkinse (MYSQLI_REPORT_ERROR) ve istenen işlem başarısız olursa bir uyarı üretilir. Ek olarak, kip MYSQLI_REPORT_STRICT ise bunun yerine mysqli_sql_exception istisnası oluşur.

    Örnekler

    See mysqli_multi_query().

    this function returns FALSE when you have an error in your syntax in one of your queries, so be carefull with this type of construction when tracking errors:

    <?php

    //error in the second sub query 
    $result = $db->multi_query("select * from news; seleeeeeeect id from news; update news set title='new title' where id= 12 ");

    //code inside object class
    $this->_db = new Mysqli($host, $user, $password, $database, $port, $socket);
           
    do {
            $result = $this->_db->store_result();
            $this->_resultMulti[] = $result;
            $this->_errnoMulti[] = $this->_db->errno;

        if(    is_object($result)) {
                $result->free_result();
        }
                   
    } while(    $this->_db->next_result());

    ?>

    in this construction all you have in the $this->_errnoMulti is :

    array(1) {
      [0]=>
      int(0)
    }

    which means that there are no errors if you are not checking how many queries are executed!
