How to use MAX function in yii2 query? - mysql

Question

I have a query:
SELECT hs.*
FROM hire_screening hs
INNER JOIN
(SELECT resume_id, MAX(created_date) AS MaxDateTime
FROM hire_screening
GROUP BY resume_id) hire_screening
ON hs.resume_id = hire_screening.resume_id
AND hs.created_date = hire_screening.MaxDateTime
This is my table:
I need the answer like this:
I tried this:
$query = HireScreening::find()-
->select(["hire_screening.screening_id","hs.resume_id",
"MAX(hs.created_date) AS
MaxDateTime","hs.screening_by","hsl.screening_level as
hr_level","hss.screening_status as
hr_status","hr.candidate_name","hsm.screening_mode as
hr_mode","hire_screening.created_date","hs.screening_date"])
->innerJoin('hire_screening as hs','hs.resume_id =
hire_screening.resume_id')
->leftJoin('hire_screening_level as
hsl','hire_screening.screening_level = hsl.id')
->leftJoin('hire_screening_mode as
hsm','hire_screening.screening_mode = hsm.id')
->leftJoin('hire_screening_status as
hss','hire_screening.screening_status = hss.id')
->leftJoin('hire_resume as
hr','hire_screening.resume_id=hr.resume_id')
//->where(['hire_screening.created_date = MaxDateTime'])
->groupBy(['resume_id']);
//->having(['hire_screening.created_date' =>
'hs.MaxDateTime']);
$query->orderBy(['created_date' => SORT_DESC]);
But it didn't shows the answer. I need the distinct resume_id's with latest created date. The sql query shows the correct answer.I want to write this query in my search model. Please help me to convert this query into yii2.

If there is a table MyTable, then you can use simplier query grouping the table by resume_id:
SELECT
screening_id,
resume_id,
screening_by,
screening_date,
screening_level,
screening_mode,
screening_status,
reject_reason,
remarks,
created_by,
MAX(created_date) AS created_date
FROM MyTable
GROUP BY resume_id;
Using simplify query helps to avoid an errors. Also you could create a view or a stored procedure using the query and call this from your PHP code.
