 10/5/2019      2           20
 10/5/2019      3           20

  11/5/2019     1       30
  11/5/2019     2       60
  12/5/2019     1       30
  12/5/2019     2       20
  12/5/2019     3       50

I want result order by date and after sum of price group by catid,

I have tried multiple query applied but get exact solution. I have spent so much time.

I have tried bellow queries

SELECT * FROM (SELECT * FROM `table`  ORDER BY `date` DESC) as tbl
 GROUP BY tbl.`catid`

---

SELECT *
FROM `table` 
GROUP BY `date` ORDER BY `date` DESC

---

SELECT * 
FROM (
    SELECT * FROM `table`  
    ORDER BY `date` DESC
) AS sub
GROUP BY `catid` ORDER BY `date` DESC

Answer 1

the columns you can use in order by and group by can be different

You could use group by and sum directly

select date, catid, sum(price)
from my_table 
group by date, catid
order by date, sum(price), catid
