How to select field with another name

In below code how to select FundTransferDate with group year like year(FundTransferDate).

In mysql query it is working but how I can apply in cakephp query.

$data_array = $this->Finances->find();
$data_array = $data_array
        'total_amount' => $data_array->func()->sum('CurrencyAmount')
        'FundTransferStatus' => 'Succeeded', 
        'ProcessingStatus' => 'Closed'

I am not so clear of what you want, but maybe a custom function can help. See Query
