How to total "AS" column in mysql query? - mysql

Question

I need SUM of AS column "profit"and "purch_price". I tried few things group by stock.id etc but it is not giving me same answer. please let me know how to take their sum.
SELECT
jobc_consumble.Stock_id,
jobc_consumble.issued_qty,
jobc_consumble.total,
p_purch_stock.Price,
p_purch_stock.Price * jobc_consumble.issued_qty AS "purch_price",
jobc_consumble.total -(SELECT purch_price) AS "profit"
FROM
jobc_consumble
INNER JOIN p_purch_stock ON jobc_consumble.stock_id = p_purch_stock.stock_id
WHERE
DATE_FORMAT(
jobc_consumble.issue_time,
'%Y-%m-%d'
) BETWEEN '2018-07-03' AND '2018-07-03'
Output should be like so :
I want sum of last two columns.
sum of PROFIT: 1105
sum of purch_price: 11000

Just repeat the logic in your SELECT clause:
SELECT
j.Stock_id,
j.issued_qty,
j.total,
p.Price,
p.Price * j.issued_qty AS purch_price,
j.total - (p.Price * j.issued_qty) AS profit
FROM jobc_consumble j
INNER JOIN p_purch_stock p
ON j.stock_id = p.stock_id
WHERE
DATE_FORMAT(j.issue_time, '%Y-%m-%d') = '2018-07-03';
For some notes, the only alternative to repeating the purchase price logic would be to wrap your current query as a subquery and reuse the alias. But, that would probably not be too performant. Your DATE_FORMAT expression does not make much sense, because the range is just a single day. If you don't like my version, then let us know what logic you really intended.
