### Question
Calculate the percentage of order via in-store channel of customer "Medline".

### Hint
Medline is the name of the customer; DIVIDE(COUNT(OrderNumber where Sales Channel = 'In-Store' and Customer Names = 'Medline'), COUNT(OrderNumber where Customer Names = 'Medline')) as percentage;

### SQL
SELECT CAST(SUM(CASE WHEN T1.`Sales Channel` = 'In-Store' THEN 1 ELSE 0 END) AS REAL) * 100 / COUNT(T1._CustomerID) FROM `Sales Orders` AS T1 INNER JOIN Customers AS T2 ON T2.CustomerID = T1._CustomerID WHERE T2.`Customer Names` = 'Medline '

### Question
Describe the customer names and lasting delivery periods for the product of "Bedroom Furniture" by wholesale channel in 2019.

### Hint
delivery period in 2019 means time between placing of an order and the receipt of product and refers to SUBTRACT(DeliveryDate, OrderDate) where SUBSTR(OrderDate, -2 ) = '19'; Sales Channel = 'Wholesale'; Product Name = 'Bedroom Furniture';

### SQL
SELECT T1.`Customer Names`, T2.DeliveryDate FROM Customers AS T1 INNER JOIN `Sales Orders` AS T2 ON T2._CustomerID = T1.CustomerID INNER JOIN Products AS T3 ON T3.ProductID = T2._ProductID WHERE T2.`Sales Channel` = 'Wholesale' AND T3.`Product Name` = 'Bedroom Furniture' AND T2.OrderDate LIKE '%/%/19'

### Question
Describe the customer names and product names which had over 3800 USD in net profit.

### Hint
over 3800 USD in net profit refers to SUBTRACT(Unit Price, Unit Cost) where Net Profit > 3800;

### SQL
SELECT DISTINCT `Customer Names`, `Product Name` FROM ( SELECT T1.`Customer Names`, T3.`Product Name` , REPLACE(T2.`Unit Price`, ',', '') - REPLACE(T2.`Unit Cost`, ',', '') AS T FROM Customers T1 INNER JOIN `Sales Orders` T2 ON T2._CustomerID = T1.CustomerID INNER JOIN Products T3 ON T3.ProductID = T2._ProductID ) WHERE T > 3800

### Question
Calculate the total net profit of the store located in highest median income city.

### Hint
net profit can be computed as SUBTRACT(Unit Price, Unit Cost); highest median income city refers to City Name where MAX(Median Income);

### SQL
SELECT SUM(REPLACE(T1.`Unit Price`, ',', '') - REPLACE(T1.`Unit Cost`, ',', '')) FROM `Sales Orders` AS T1 INNER JOIN `Store Locations` AS T2 ON T2.StoreID = T1._StoreID ORDER BY T2.`Median Income` DESC LIMIT 1

### Question
Among the sales team in South region, write down the numbers of orders made by the sales team ID of one digit.

### Hint
sales team ID of one digit refers to _SalesTeamID BETWEEN 1 AND 9; numbers of orders refer to COUNT(OrderNumber);

### SQL
SELECT COUNT(T1.OrderNumber) FROM `Sales Orders` AS T1 INNER JOIN `Sales Team` AS T2 ON T2.SalesTeamID = T1._SalesTeamID WHERE T2.Region = 'South' AND T2.SalesTeamID BETWEEN 1 AND 9 GROUP BY T2.SalesTeamID HAVING COUNT(T1.OrderNumber)
