SQLZoo

I've been practicing SQL a lot recently. SQLZoo is a classic and great place to practice SQL. Today, I worked through the
Adventure Works set of problems...I liked this one a lot because of the cycling related theme. Spring is around the corner and this problem set made me excited to be thinking about my bicycle. Anyway, below is some of the problem set:

-- How many items with ListPrice more than $1000 have been sold?

SELECT COUNT(*) AS count
FROM SalesOrderDetail
JOIN Product
ON SalesOrderDetail.ProductID = Product.ProductID
WHERE Product.ListPrice > 1000;

-- Give the CompanyName of those customers with orders over $100000. Include the subtotal plus tax plus freight.

SELECT Customer.CompanyName
FROM SalesOrderHeader
JOIN Customer
ON SalesOrderHeader.CustomerID = Customer.CustomerID
WHERE SalesOrderHeader.SubTotal + SalesOrderHeader.TaxAmt + SalesOrderHeader.Freight > 100000;


 -- Find the number of left racing socks ('Racing Socks, L') ordered by CompanyName 'Riding Cycles'

SELECT SUM(SalesOrderDetail.OrderQty) 
FROM SalesOrderDetail
JOIN Product
ON SalesOrderDetail.ProductID = Product.ProductID
JOIN SalesOrderHeader
ON SalesOrderDetail.SalesOrderID = SalesOrderHeader.SalesOrderID
JOIN Customer
ON SalesOrderHeader.CustomerID = Customer.CustomerID
WHERE Product.Name = 'Racing Socks, L' AND Customer.CompanyName = 'Riding Cycles';```
