CakePHP 3 - 查找多个条件

Posted 2021-03-29

我正在尝试进行查询以查找具有特定集或ID的所有行。

例如，我想找到一个具有以下值之一的device_id字段：1 3 5

我尝试将其添加为数组，但我收到一条错误消息：无法将值转换为整数

这是我的代码：

$revenuesQuery = $revenues->find('all', [
        'conditions' => [
            'device_id' => [1, 3, 5],
            'date' => date('Y-m-d')
        ]
    ]);

如您所见，device_id是一个整数数组（3和4），我不想拥有其中一个（3或4）的行。如果我将代码更改为不使用数组而是使用这样的硬整数：

$revenuesQuery = $revenues->find('all', [
        'conditions' => [
            'device_id' => 3,
            'date' => date('Y-m-d')
        ]
    ]);

它工作得很好？

这是我的调试查询：

'(help)' => 'This is a Query object, to get the results execute or iterate it.',
'sql' => 'SELECT Revenues.id AS `Revenues__id`, Revenues.device_id AS `Revenues__device_id`, Revenues.revenue AS `Revenues__revenue`, Revenues.date AS `Revenues__date` FROM revenues Revenues WHERE (device_id = :c0 AND date = :c1)',
'params' => [
    ':c0' => [
        'value' => [
            (int) 0 => (int) 3,
            (int) 1 => (int) 4
        ],
        'type' => 'integer',
        'placeholder' => 'c0'
    ],
    ':c1' => [
        'value' => '2017-12-17',
        'type' => 'date',
        'placeholder' => 'c1'
    ]
]

提前致谢。

答案

您正在寻找的是IN operator。

将单词IN添加到字段名称的末尾。

$revenuesQuery = $revenues->find('all', [
    'conditions' => [
        'device_id IN' => [1, 3, 5],
        'date' => date('Y-m-d')
    ]
]);

或者，查询表达式构建器更详细，是我在Cakephp中创建查询的首选方法。

$q = $revenues->query();
$revenuesQuery = $revenues->find('all')
    ->where([
        $q->newExp()->in('device_id', [1, 3, 5]),
        $q->newExp()->eq('date', $q->func()->now())
    ]);
