Bundle with order numbers - sql

Question

I am trying to generate a report where I want to get total sale values and quantities .
explanation:
When customers some products they get free gift , so items are two types standard and free gift . When they buy standard item they get free gift but not all the customers are eligible for it. In database they are hard coded as standard =0 and free gift as =1.
Aim 1: I would like to get only number of orders with free gifts and the total of that orders.
Aim 2: I want to count each count of free gift to find out top 10.
All the fields are in brackets.
below is simple example .
Hope this make sense. Thank you .
Results :
my script:
select
oh.[order date],
oh.[order guid],
[Item No_] as SKU
,ti.[Description],
ol.[quantity],
ol.Amount,
[EMS Available Quantity] as Stock_Qty,
(case when [Product Type]=0 then 'Standard'
when[Product Type]=1 then 'free_gift'
end) as Product_Type
from [Big$Item] TI
Inner join [Big$Inventory] I
ON I.[Item No_] = TI.[No_]
inner join [Big$Order Line] ol
on ti.[No_]=ol.[No_]
inner join [Big$Order header]oh
on oh.[order guid]=ol.[order guid]
where [Product Type] in ('0','1')
and oh.[order date] between'2017-06-12' and '2017-06-18'
order by [order date] asc

Answer 1

finally i have a solution - maybe not the most beautiful one - but it is working:
i have also added the create statement and the testdata insert - you can also reproduce it with this test link: http://rextester.com/JRV11837
The first Select just returns all orderguid which have at least one free gift.
The second Select i used to join includes the total amount of each order. As i use an INNER JOIN the final result will be just orders which include freegifts.
Finally i just group the resultset by the description of the freegift.
CREATE TABLE mygifttable
( Date datetime
,orderguid varchar(10)
,description varchar(55)
,sku int
,amount decimal)
;
INSERT INTO mygifttable VALUES
('2017-06-01', '1234', 'Sony Speakers' , 25, 100),
('2017-06-01', '1234', 'Sony Tv' , 23, 250),
('2017-06-01', '1234', 'Tv stand' , 11, 0),
('2017-06-01', '1235', 'Samsung Speakers', 28, 150),
('2017-06-01', '1235', 'Samsung Tv' , 26, 350),
('2017-06-01', '1235', 'Wall mount' , 10, 0),
('2017-06-01', '1236', 'Sony Speakers' , 25, 100),
('2017-06-01', '1236', 'Sony Tv' , 23, 250),
('2017-06-01', '1236', 'Tv stand' , 11, 0),
('2017-06-01', '1237', 'Apple mobiles' , 29, 900),
('2017-06-01', '1237', 'Apple cable' , 30, 800)
;
SELECT freegifttable.description
,SUM(freegifttable.freegift) as Free_Gifts
,SUM(totalamount.orderamount) as Total_Orderamount
FROM (
SELECT description
,orderguid
,SUM(IIF(amount = 0, 1,0)) as freegift
FROM mygifttable
GROUP BY description, orderguid
HAVING SUM(IIF(amount = 0, 1,0)) != 0
) freegifttable
INNER JOIN
(
SELECT orderguid
,SUM(amount) as orderamount
FROM mygifttable
GROUP BY orderguid
) totalamount
ON totalamount.orderguid = freegifttable.orderguid
GROUP BY freegifttable.description
