i am trying to create a query where i want to convert my rows into column with row panel_name GROUP BY and arrange by last created_at of individual date. My data is coming in the column format but not showing it with the date specific. I tried multiple queries but not game me the results. Here is how my table structure looks like.
+--------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------------+------------------+------+-----+---------+----------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| panel_name | varchar(191) | YES | | NULL | |
| panel_number | varchar(191) | YES | | NULL | |
| display_from | date | YES | | NULL | |
| open_time | varchar(191) | YES | | NULL | |
| close_time | varchar(191) | YES | | NULL | |
| created_at | timestamp | YES | | NULL | |
| updated_at | timestamp | YES | | NULL | |
| deleted_at | timestamp | YES | | NULL | |
+--------------+------------------+------+-----+---------+----------------+
Here is how my data looks like currently:
+-----+-------------------+--------------+--------------+-----------+------------+---------------------+---------------------+---------------------+
| id | panel_name | panel_number | display_from | open_time | close_time | created_at | updated_at | deleted_at |
+-----+-------------------+--------------+--------------+-----------+------------+---------------------+---------------------+---------------------+

+-----+-------------------+--------------+--------------+-----------+------------+---------------------+---------------------+---------------------+
And here is how i want to see the results
+--+-------------------+------------+-----------+-------------------+------------+
| | TARA MUMBAI DAY | TIME | MILAN DAY | TARA MUMBAI NIGHT | created_at |
+--+-------------------+------------+-----------+-------------------+------------+
123-1*-*** 123-**-*** NULL NULL 2019-11-13
128-74-446 1**-**-*** 700-74-789 700-74-789 2019-11-11
So here is how much i have tried so far, but dosent seems to show the result i want.
SELECT
max(r0.id),
r1.panel_name AS "TIME",
r2.panel_name AS "TARA MUMBAI DAY",
r3.panel_name AS "MILAN DAY",
r4.panel_name AS "TARA MUMBAI NIGHT",
r0.DateOnly
FROM
(SELECT
id, panel_name,panel_number, DATE(created_at) as DateOnly
FROM
foduu_potresult
) r0
LEFT JOIN foduu_potresult r1
ON r1.id = r0.id AND r1.panel_name = 'TIME'
LEFT JOIN foduu_potresult r2
ON r2.id = r0.id AND r2.panel_name = 'TARA MUMBAI DAY'
LEFT JOIN foduu_potresult r3
ON r3.id = r0.id AND r3.panel_name = 'MILAN DAY'
LEFT JOIN foduu_potresult r4
ON r4.id = r0.id AND r4.panel_name = 'TARA MUMBAI NIGHT'
GROUP BY
r0.DateOnly
ORDER BY
r0.id DESC
Any suggestions with this kind of query? How i can show proper results.
You can use a correlated subquery to filter the table and retain the record that has the latest created_at for each panel_name and day of created_at. Then, you can use conditional aggregation to pivot the results:
select
max(case when panel_name = 'TARA MUMBAI DAY' then panel_number end ) `TARA MUMBAI DAY`,
max(case when panel_name = 'TIME' then panel_number end ) `TIME`,
max(case when panel_name = 'MILAN DAY' then panel_number end ) `MILAN DAY`,
max(case when panel_name = 'TARA MUMBAI NIGHT' then panel_number end ) `TARA MUMBAI NIGHT`,
date(created_at) created_at
from mytable t
where created_at = (
select max(t1.created_at)
from mytable t1
where
date(t1.created_at) = date(t.created_at)
and t1.panel_name = t.panel_name
)
group by date(created_at)
TARA MUMBAI DAY | TIME | MILAN DAY | TARA MUMBAI NIGHT | created_at :-------------- | :--------- | :--------- | :---------------- | :--------- 128-74-446 | ***-**-*** | 700-74-789 | 700-74-789 | 2019-11-11 123-1*-*** | 123-**-*** | null | null | 2019-11-13
