How to get Sale data of every month of a year - php

Question

I'm trying to get Sale Data of every month of particular year, but I'm having a problem building a query for it.
Here is What I've tried
SELECT COUNT(`id`) AS `total_order`
FROM orders
WHERE date BETWEEN ? AND ?
GROUP BY `total_order`
HERE is How my table look like
----------------------------------------
| id | item_name | amount | time |
| 21 | item_1 | 10 | 1506675630 |
| 22 | item_2 | 30 | 1506675630 |
| 23 | item_3 | 70 | 1506675630 |
| 24 | item_4 | 100 | 1506675630 |
----------------------------------------
Now here is what i want from the query
1 - Total Sales amount made from the beginning of the year till today.
2 - Sales made Today
3 - Sales made in Last Month
4 - Sales Made in Last 3 month
5 - Sales Made in Last 6 Month
6 - Total Number of Sales made in every month of this particular year
for e.g -
January - 20
Feb -100
March - 200 & so on.
How can i achieve this complex query?

Answer 1

SELECT `id` AS `Order_Number`, item_name, SUM(Amount)
FROM orders
WHERE time >= '01/01/17'
GROUP BY date
That would give you your first result. Try the others and let me know what you get

Answer 2

This answers your first question
SELECT
DATE_FORMAT(FROM_UNIXTIME(time), '%Y-%m') as interval,
COUNT(*) AS sales_made,
SUM(amount) AS sales_amount
FROM orders
WHERE
time BETWEEN UNIX_TIMESTAMP('2017-01-01') AND UNIX_TIMESTAMP('2018-01-01')
GROUP BY 1
ORDER BY 1;

Answer 3

Here is what i think would work:
for the first 5 queries try something like this.
SELECT SUM(amount)
FROM orders
WHERE DATE_FORMAT(FROM_UNIXTIME(`orders.time`), '%Y-%m-%d') BETWEEN ? AND ?
And for the last one you'll need :
SELECT DATE_FORMAT(FROM_UNIXTIME(`orders.time`), '%Y-%m-%d') AS 'date', SUM(amount)
FROM orders
WHERE date between ? AND ?
GROUP BY DATE_FORMAT(date, '%Y%m')
You can try without the FROM_UNIXTIME if it doesnt work.
