Doctrine 1 select column with duplicate values

Question

I have a query that will display columns with duplicate or with more than 1 values.I can display it using sql

select date_created,loan_id,count(1) as cnt
from collections
group by date_created,loan_id
having count(1)>1;

I want that to convert to Doctrine 1 query,I tried

 public function getDuplicateDatePayment() {
    $q = $this->createQuery('c')
               ->select('c.date_created,c.loan_id,c.count(1) as cnt')
               ->groupBy('c.date_created','c.loan_id')
               ->having('c.count(1) > 1');
               return $q->execute();
}     

But it only return errors.Any Idea on how to correctly convert the said working sql into a doctrine 1 query?

SQLSTATE[42000]: Syntax error or access violation: 1630 FUNCTION c.count     does not exist. Check the 'Function Name Parsing and Resolution' section in the Reference Manual. Failing Query: "SELECT c.id AS c__id, c.date_created AS c__date_created, c.loan_id AS c__loan_id, c.count(1) AS c__0, c.count(1) AS c__0 FROM collections c GROUP BY c.date_created HAVING c.count(1) > 1"

Answer 1

I hope the problem may be with count. Try the following

public function getDuplicateDatePayment() {
    $q = $this->createQuery('c')
               ->select('c.date_created,c.loan_id,count(c.1) as cnt')
               ->groupBy('c.date_created','c.loan_id')
               ->having('c.count(1) > 1');
               return $q->execute();
}
