可以使用多个/嵌套的MySQLi语句吗? [英] Possible to use multiple/nested MySQLi statements?

问题描述

是否可以在上一条语句的fetch()调用中包含MySQLi prepared statement?如果没有，最好的解决方法是什么?

Is it possible to have a MySQLi prepared statement within the fetch() call of a previous statement? If not, what's the best way around it?

示例代码:

if($stmt = $link->prepare("SELECT item FROM data WHERE id = ?")) {
    $stmt->bind_param("i", $id);
    $stmt->execute();
    $stmt->bind_result($item);
    while( $stmt->fetch() ) {
        /* Other code here */
        $itemSummary = $item + $magic;
        if($stmt2 = $link->prepare("INSERT INTO summaries (itemID, summary) VALUES (?, ?)")) {
            $stmt2->bind_param("is", $itemID, $itemSummary);
            $stmt2->execute();
            $stmt2->close();
        }
    }
}
