[英]Zend Framework 2 returning object as a query result
I have a query in ZF2 like following: 我在ZF2中有一个查询,如下所示:
public function BrandWallBrandsById($userId,$brandId,$startDate,$endDate)
{
$select = new Select();
$select->from(array('p' => $this->table), array('id'));
$select->join(array('b' => 'brands'), 'p.brandId = b.id', array('id','name', 'cover', 'slogan', 'startDate', 'homepage'));
$select->columns(array(new Expression('SUM(p.points) as points'), "userId", "brandId"));
$select->order("p.points desc");
$select->group("p.brandId");
$where = new Where();
$where->notEqualTo("p.points", 0);
$where->equalTo("p.userId", $userId);
$where->equalTo("p.brandId", $brandId);
$where->between("p.time", $startDate, $endDate);
$select->where($where);
return $this->historyTable->selectWith($select)->toArray();
}
Since I'm returning only a single object, can I return an object from this query instead of an array[0] ?? 由于我只返回一个对象,我可以从此查询而不是数组[0]返回一个对象吗? Is there any way to do this ?
有没有办法做到这一点?
If you're expecting a signle row from your query then you can use current()
. 如果您期望查询中出现一个单行,那么您可以使用
current()
。 Modify the last line of your code, juste like this: 修改你的代码的最后一行,像这样:
$row = $this->historyTable->selectWith($select)->current();
if(!$row){
throw new Exception('No row found');
}
return $row;
