Question

我正在尝试从我的视频数据库中获取视频，选择基于external_id和language_id（两个整数）的唯一组合。我尝试了以下代码，但看起来只有findFirst()才能获得第一个标准

$video = Video::findFirst("language_id=" . $language->id . " and external_id=" . $external->id);

有人可以帮助我如何正确使用具有多个标准的findFirst吗？

Answer 1

尝试绑定参数与连接它们。更安全，它可能会识别错误区域

$video = Video::findFirst(
    [
        'columns'    => '*',
        'conditions' => 'language_id = ?1 AND external_id = ?2',
        'bind'       => [
            1 => $language->id,
            2 => $external->id,
        ]
    ]
);

Answer 2

find（）和findFirst（）方法都接受指定搜索条件的关联数组：

$robot = Robots::findFirst(array(
    "type = 'virtual'",
    "order" => "name DESC",
    "limit" => 30
));

$robots = Robots::find(array(
    "conditions" => "type = ?1",
    "bind"       => array(1 => "virtual")
));


// What's the first robot in robots table?
$robot = Robots::findFirst();
echo "The robot name is ", $robot->name, "\n";

// What's the first mechanical robot in robots table?
$robot = Robots::findFirst("type = 'mechanical'");
echo "The first mechanical robot name is ", $robot->name, "\n";

// Get first virtual robot ordered by name
$robot = Robots::findFirst(array("type = 'virtual'", "order" => "name"));
echo "The first virtual robot name is ", $robot->name, "\n";
