php - Mongodb Multiple and语句使用PHP代码

Question

我想要使​​用 PHP 代码从 mongodb 进行如下查询：

select * from orders where mrn=1234 and status!=cancelled and status!=delivered and status!=draft

我尝试了以下不起作用的代码：

$filterpatient = array("order.patientinfo.mrn" => $reqresult, '$and' => array( 
    array('order.orderitem.status' => array('$ne' => array('cancelled','delivered')))
    ));
$cursor = $collection->find($filterpatient)->sort(array('_id'=>-1));

Answer 1

Try:
$collection->find(array("order.patientinfo.mrn" => $reqresult, 'order.orderitem.status' => array('$nin' => array("cancelled","delivered","draft"))))->sort(array('_id'=>-1));

MongoDB查询：

db.orders.find({"mrn":1234,"status":{"$nin":["cancelled","delivered","draft"]}});

Answer 2

您可以使用MongoDB_DataObject如下：

$model = new MongoDB_DataObject();

$model->query("select * from orders where mrn=1234 and status!='cancelled' and status!='delivered' and status!='draft'");

while ($model->fetch()) {
    var_dump($model);
} 

或者：

$model = new MongoDB_DataObject('orders');

$model->whereAdd("mrn=1234 and status!='cancelled' and status!='delivered' and status!='draft'");

$model->find();

while ($model->fetch()) {
    var_dump($model);
}    

Answer 3

您的查询不正确，首先您的 mrn 查询也应该在 $and 子句中，并且您应该使用$nin（不在数组中）作为您的状态。您的状态查询也被两个array(子句包围。

$filterpatient = array('$and' => array(
    "order.patientinfo.mrn" => $reqresult, 
    "order.orderitem.status" => array('$nin' => array('cancelled','delivered', 'draft'))
));
