php - 如何在 PhalconPHP 中为单个表列实现多个条件

Question

在 status 为 abanadoned 或 completed 的计划中查找节省的金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(bind):

$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
    ]
]);

如果 IN 子句有更多值，第二个选项更优雅、更实用。
