MYSQL查询中的多个Select语句

Question

I have aa mysql table contaning date wise sale of products on different marketplaces .

Date   Marketplace   Sale 
1      flipkart       1000
1      flipkart       500
1      amazon          200
1      amazon         1500
1      amazon          700
2      myntra          500
2      flipkart       1000

I want a single mysql statement that gives me date wise gross sale of different marketplaces (amazon,flipkart etc) for a month like in this case on

1st of month flipkart gross sale is 1500 (1000+500) , amazon gross sale 2400 (1500+700+200)

I have this query :

SELECT  date, (Select sum(gross_sale) from sku where marketplace='flipkart') as flipkart, (Select sum(gross_sale) from sku where marketplace='Myntra') as myntra, sum(gross_sale) as countdate FROM sku WHERE   date >= '2017-11-01' AND
        date   <= '2017-11-30' GROUP BY date ORDER BY date ASC limit 30 ;

but the select subquery doesn't give me date wise distribution , instead the total gross sale of month . how to solve that problem . Please help. thanks in advance.

Answer 1

Mysql give you sum() and group by function for the task. You can retrieve the required result by following query

select Date, Marketplace, sum(Sale) from table group by Date, Marketplace

sum() will be sum all the prices of same marketplace with the help of group by

After your comment

If you don't want to use loop and you need single result with query, then you just need where clause

select Date, Marketplace, sum(Sale) from table where Marketplace = 'flipkart'

Answer 2

Try this:

SELECT Date,Marketplace, SUM(Sale) 
FROM tab111 where date =1
Group By Marketplace 

Answer 3

Have you tried doing a union:

select date,marketplace,sum(sales) from yourtable where marketplace='flipkart'

union

select date,marketplace,sum(sales) from yourtable where marketplace='amazon'

Here's the sqlfiddle

Answer 4

Try this

SELECT 
    sk.date,
    sum(sk1.sale) as flipkart_sum_sale,
    sum(sk2.sale) as amanzon_sum_sale
FROM
    sku sk
        LEFT JOIN
    sku sk1 ON sk.id = sk1.id
        AND sk1.marketplace = 'flipkart'
        LEFT JOIN
    sku sk2 ON sk.id = sk2.id
        AND sk2.marketplace = 'amazon'
GROUP BY sk.date;

Answer 5

select Date,Marketplace, sum(Sale) from table group by Marketplace;
