mysqli::next_result

    mysqli_next_result

    (PHP 5, PHP 7, PHP 8)

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

    Опис

    Об'єктно-орієнтований стиль

    public mysqli::next_result(): bool

    Процедурний стиль

    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().

    Параметри

    mysql

    Тільки процедурний стиль: об'єкт mysqli, якого повертає функція mysqli_connect() або mysqli_init()

    Значення, що повертаються

    Повертає true у разі успіху або false в разі помилки. Also returns false if the next statement resulted in an error, unlike mysqli_more_results().

    Помилки/виключення

    Якщо увімкнені звіти про помилки mysqli (MYSQLI_REPORT_ERROR) і запитана операція не виконалась, буде виведено попередження, але якщо встановлено режим MYSQLI_REPORT_STRICT, буде викинуто виключення mysqli_sql_exception.

    Приклади

    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!

    Stored procedures few rowset example:
