Specifying a column to compare in HAVING subquery - sql

Question

I am trying to compare sales from different quarters by stores in adventureworks 2014.
My code is as following
SELECT store.BusinessEntityID as "StoreID", "Name"
from sales.SalesOrderHeader
inner join sales.customer
on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store
on sales.customer.StoreID= sales.store.BusinessEntityID
where (OrderDate between '2014-01-01' and '2014-03-31')
and (OnlineOrderFlag = 0)
group by store.BusinessEntityID, "Name"
having format(round(sum(subtotal),2),'###,###,###.##') > format(round(sum(subtotal),2),'###,###,###.##') IN
(
SELECT store.BusinessEntityID as "StoreID",
format(round(sum(subtotal),2),'###,###,###.##') "Ventes2013_Q4"
from sales.SalesOrderHeader
inner join sales.customer on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store on sales.customer.StoreID= sales.store.BusinessEntityID
where (orderdate between '2013-10-01' and '2013-12-31') and OnlineOrderFlag = 0
group by store.BusinessEntityID
)
Both my main query and my subquery work individually, but I am not able to specify the column i want to compare it with in the second part of the having. When trying IN it gives me an incorrect syntax, and it does not work when using the column name either. It also did not work when adding a sales column in the main query
Can anyone point me in the right direction?

This is a simple way to do it (translating from your code)
SELECT StoreID, Name
FROM (
SELECT store.BusinessEntityID as "StoreID", "Name", sum(stubtotal) as sum
from sales.SalesOrderHeader
inner join sales.customer on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store on sales.customer.StoreID= sales.store.BusinessEntityID
where (OrderDate between '2014-01-01' and '2014-03-31') and (OnlineOrderFlag = 0)
group by store.BusinessEntityID, "Name"
) first
JOIN (
SELECT BusinessEntityID, sum(subtotal) as sum
from sales.SalesOrderHeader
inner join sales.customer on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store on sales.customer.StoreID= sales.store.BusinessEntityID
where (orderdate between '2013-10-01' and '2013-12-31') and OnlineOrderFlag = 0
group by store.BusinessEntityID
) as sub on sub.BusinessEntityID = furst.BusinessEntityID
AND sub.sum < first.sum
However there is a better way in sql server... one sec.
This will give to you totals by quarter and store:
SELECT
store.BusinessEntityID as StoreID,
Name,
year(OrderDate) as y,
quarter(orderdate) as q,
sum(stubtotal) as sum
from sales.SalesOrderHeader
inner join sales.customer on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store on sales.customer.StoreID= sales.store.BusinessEntityID
group by store.BusinessEntityID, Name, year(OrderDate), quarter(orderdate)
Now create a view
CREATE VIEW quarterview as
SELECT
store.BusinessEntityID as StoreID,
Name,
year(OrderDate) as y,
quarter(orderdate) as q,
sum(stubtotal) as sum
from sales.SalesOrderHeader
inner join sales.customer on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store on sales.customer.StoreID= sales.store.BusinessEntityID
group by store.BusinessEntityID, Name, year(OrderDate), quarter(orderdate)
"I want to show the stores that have more sales in 2014Q1 than in 2013Q4"
SELECT *
FROM quarterview first
WHERE q = 1 and year = 2014
then
SELECT *
FROM quarterview first
JOIN quarterview second ON second.q = 4 and second.year=2013 and first.sum > second.sum
WHERE first.q = 1 and first.year = 2014
With your fab new quarter view all the client request are easy to do with just a couple of lines of code.

With Ventes2014_Q1 as(
SELECT store.BusinessEntityID as "StoreID", "Name",format(round(sum(subtotal),2),'###,###,###.##') "Ventes2014_Q1"
from sales.SalesOrderHeader
inner join sales.customer
on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store
on sales.customer.StoreID= sales.store.BusinessEntityID
where (OrderDate between '2014-01-01' and '2014-03-31')
and (OnlineOrderFlag = 0)
group by store.BusinessEntityID, "Name"
),Ventes2013_Q4
(
SELECT store.BusinessEntityID as "StoreID",
format(round(sum(subtotal),2),'###,###,###.##') "Ventes2013_Q4"
from sales.SalesOrderHeader
inner join sales.customer on sales.SalesOrderHeader.CustomerID = sales.customer.CustomerID
inner join sales.store on sales.customer.StoreID= sales.store.BusinessEntityID
where (orderdate between '2013-10-01' and '2013-12-31') and OnlineOrderFlag = 0
group by store.BusinessEntityID
)
select "StoreID", "Name" from Ventes2014_Q1
where "StoreID" exists
(select "StoreID" from Ventes2013_Q4 where Ventes2013_Q4."StoreID"=Ventes2014_Q1."StoreID" and Ventes2014_Q1."Ventes2014_Q1">Ventes2013_Q4."Ventes2013_Q4")
