Multiple Conditions with Left Join in Zend Framework - sql

Question

I am facing an issue while working with Zend Framework. Basically, I am trying to add an AND operator in a sub query using Left join. Please see the following query that my code is producing:
SELECT `d`.*, count(status) FROM `deal` AS `d` LEFT JOIN `payments` ON `payments`.deal_id = `d`.deal_id GROUP BY `d`.`deal_id` ORDER BY `created_date` desc
Code is:
$select = $this->_db->select()
->from(array('d'=>'deal'))
->joinLeftUsing('payments', 'deal_id', array('count(status)'))
->order("created_date $sortOrder")
->group("d.deal_id");
However, I want to add one more condition in my sub query i.e. Status = 1, please see the following output that I am willing to get.
SELECT `d`.*, count(status) FROM `deal` AS `d` LEFT JOIN `payments` ON `payments`.deal_id = `d`.deal_id AND status = 1 GROUP BY `d`.`deal_id` ORDER BY `created_date` desc
Let me know if someone have an idea about how I can achieve the same.
Thanks,

Answer 1

I would recommend using joinLeft instead of joinLeftUsing
$select = $this->_db->select()
->from(array('d'=>'deal'))
->joinLeft('payments', 'payments.deal_id = d.deal_id and status = 1',
array('count(status)'))
->order("created_date $sortOrder")
->group("d.deal_id");
gives me
SELECT `d`.*, count(status) FROM `deal` AS `d`
LEFT JOIN `payments` ON payments.deal_id = d.deal_id and status = 1
GROUP BY `d`.`deal_id` ORDER BY `created_date ` ASC

Answer 2

We can use expression in Zend 3:
$join = new \Zend\Db\Sql\Expression('contractor_jobs.contractor_id = contractor_info.contractor_id AND
contractor_jobs.job_trade_id = '.$variableName.' ');
$select->join(
'contractor_jobs',
$join,
array('job_trade_id'),
$select::JOIN_LEFT
);
It works for me. You can also check as per your conditions. Thanks for asking this question.
