PhalconPHP中如何实现单个表列的多个条件

Question

在status 为abanadoned 或completed 的计划中找到节省的资金总额的正确语法是什么：

$total = self::sum([
    'column' => 'amount_saved_so_far',
    'conditions' => 'status = "completed" AND user_id = :user_id:',
    //find plans with a status of abandoned as well
    'bind' => ['user_id' => $userId]
]);

Answer 1

你可以简单地做，这是完美的解决方案：

$total = self::sum([
    'column' => 'amount_saved_so_far',
    'conditions' => '(status = "completed" OR status = "abanadoned") 
                     AND user_id = :user_id:',
    'bind' => ['user_id' => $userId]
]);

或者另一种选择是使用数组绑定：

$total = self::sum([
    'column' => 'amount_saved_so_far',
    'conditions' => 'status IN ({vars:array}) AND user_id = :user_id:',
    'bind' => [
        'vars' => ['completed', 'abanadoned'],
        'user_id' => $userId
    ]
]);

第二个选项更优雅，更实用，以防您为 IN 子句设置更多值。
