Translate SQL query into codeigniter for joomla - php

Question

I have written a SQL query which works fine and output provides all the data that I need:
Please see this screenshot:
This is the SQL code:
SELECT
P.name, C.project_id, C.choice_id, C.time_stamp, P.id,
P.description, T.type, P.activated
FROM
(SELECT P.*
FROM aqoru_pt_project P
JOIN
(SELECT id, MAX(creation_date) AS latestUpdate
FROM aqoru_pt_project
GROUP BY id) t ON t.id = P.id AND t.latestUpdate = P.creation_date) P
JOIN
(SELECT C.*
FROM aqoru_pt_project_choice C
JOIN
(SELECT project_id, MAX(time_stamp) AS latestDate
FROM aqoru_pt_project_choice
GROUP BY project_id) t ON t.project_id = C.project_id AND t.latestDate = C.time_stamp) C ON P.id = C.project_id
LEFT JOIN
aqoru_community_groups_members CGM ON P.group_id = CGM.groupid
INNER JOIN
aqoru_pt_project_type T ON P.type_id = T.id
WHERE
P.user_id = 569 OR CGM.memberid = 569
AND CGM.permissions = 1
AND P.deactivated != 1
GROUP BY
P.id
ORDER BY
P.id;
Now I need to push it into php format I was trying without great success as I am struggling mainly with the part where I try to put Join in select on the very beginning of the code. Definitely the part after ON P.id = C.project_id works fine. The problem occurs when I try to add max value from other table.
This is the code I wrote, but it does not work:
public function getProjects($userID)
{
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$columns = array('P.id', 'P.name', 'P.description', 'T.type', 'P.activated');
$query
->select(array('P.id', 'P.name', 'P.description', 'T.type', 'P.activated', 'max(C.time_stamp) as max'))
->from($db->quoteName(
->SELECT ('P.*')
->FROM ($db->quoteName('aqoru_pt_project', 'P')
->JOIN($db->quoteName(
->SELECT ('id', 'MAX(creation_date) AS latestUpdate')
->FROM ($db->quoteName('aqoru_pt_project')
->group($db->quoteName('id')) 't' . ' ON t.id = P.id AND t.latestUpdate = P.creation_date') P
->JOIN(
->SELECT ('C.*')
->FROM ($db->quoteName('aqoru_pt_project_choice', 'C')
->JOIN($db->quoteName(
->SELECT ('project_id', 'MAX(time_stamp) AS latestDate')
->FROM ($db->quoteName('aqoru_pt_project_choice'))
->group($db->quoteName('id')) 't' . ' ON t.project_id = P.project_id AND t.latestUpdate = P.time_stamp') 'C' . 'ON P.id = C.project_id'
))
->leftjoin($db->quoteName('#__community_groups_members', 'CGM') . ' ON P.group_id = CGM.groupid')
->innerjoin($db->quoteName('#__pt_project_type', 'T') . ' ON P.type_id = T.id')
->where(
$db->quoteName('P.user_id') . ' = ' . $db->quote($userID),
)
->orwhere(array(
$db->quoteName('CGM.memberid') . ' = ' . $db->quote($userID),
$db->quoteName('CGM.permissions') . ' = 1'
))
->andwhere($db->quoteName('P.deactivated') . ' != 1')
->group($db->quoteName('P.id'))
->order('P.id DESC');
/*
* Note: for some reason the queries return duplicates on the production site not on my local site
* So we must group by projectID to avoid duplicates. I am not aware what is causing this duplication
*/
return $db->setQuery($query)->loadObjectList();
}

try this
$this->db->select('P.name,C.project_id,C.choice_id,C.time_stamp,P.id,P.description,T.type,P.activated')
->from('(SELECT P.*
FROM aqoru_pt_project P
JOIN
(SELECT id, MAX(creation_date) AS latestUpdate
FROM aqoru_pt_project
GROUP BY id) t ON t.id = P.id AND t.latestUpdate = P.creation_date) P')
->join('(SELECT C.*
FROM aqoru_pt_project_choice C
JOIN
(SELECT project_id, MAX(time_stamp) AS latestDate
FROM aqoru_pt_project_choice
GROUP BY project_id) t ON t.project_id = C.project_id AND t.latestDate = C.time_stamp) C', 'P.id = C.project_id')
->join('aqoru_community_groups_members CGM', 'P.group_id = CGM.groupid', 'LEFT')
->join('aqoru_pt_project_type T', 'P.type_id = T.id')
->where('P.user_id', 569)
->or_where('CGM.memberid', 569)
->where('CGM.permissions', 1)
->where('P.deactivated !=', 1)
->group_by('P.id')
->order_by('P.id ASC')
->get();
