Question

未找到列：1054未知列＆＃39; total_points＆＃39;在＆＃39; where子句＆＃39;

protected $ tableGateway;

public function __construct(TableGateway $tableGateway)
{
    $this->tableGateway = $tableGateway;
}


public function fetchPoints$transaction_number)
{
  $results = $this->tableGateway->select(
        array('total_points' => new \Zend\Db\Sql\Expression("sum(points)")),
        array('trxnumber' => $transaction_number)
    );
    return $results[0]['total_points'];
}

它在哪里尝试获取total_points列？我认为点是列，而total_points是alyias。

Answer 1

select只接受一个参数＆＃34;其中＆＃34;。您当前的查询是：

select * from my_table where total_points=sum(points)

女巫正在抛出预期的错误。我是你想要的客人：

select sum(points) as total_points from my_table where trxnumber=X

在这种情况下你应该这样做：

$select = $this->tableGateway->getSql()->select();
$select
    ->columns(array('total_points' => new \Zend\Db\Sql\Expression("sum(points)")))
    ->where(array('trxnumber' => $transaction_number));
$result = $this->tableGateway->selectWith($select);
