- PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6USE NORTHWIND DATABASE Write a SELECT statement using the CASE function. The statement returns two columns basedon how many orders the customer has in the database. The first column is the customer name andthe second column, Membership Type, is based on which case applies to the customer:If the customer has more than 25 orders they are a Diamond Customer.If the customer has more than 15 orders they are a Gold Customer.If the customer has more than 10 orders they are a Silver Customer.If the customer has more than 5 orders they are an Iron Customer.Otherwise the customer is a Valued Customer.Database: CUSTOMER (CustomerID, LastName, FIrstName, Phone, EmailAddress) PURCHASE (InvoiceNumber, InvoiceDate, PreTaxAmount, CustomerID) PURCHASE_ITEM (InvoiceNumber, InvoiceLineNumber, Item Number, RetailPrice) ITEM (ItemNumber, ItemDesciption, Cost, ArtistLastName, ArtistFirstName) Write an SQL statement to show which cutomers bought which items, and include any items that have not been sold. Include CUSTOMER.LastName, CUSTOMER.FirstName, IvoiceNumber, InvoiceDate, ItemNumber, ItemDescription, ArtistLastName, and ArtistFirstName,. Use a join using JOIN ON syntax, and sort the results by ArtistLastName and ArtistFirstName in ascending order. Note that in Microsoft Access this require multiple queries.

- Description The Employee table holds all employees including their managers. Every employee has an Id, and there is also a column for the manager Id. +--- | Id | Name | Salary | ManagerId | +---- | 1 | 2 | 3 | 4 +---- | Joe | 70000 | 3 | Henry | 80000 | 4 | Sam | Max Given the Employee table, write a SQL query that finds out employees who earn more than their managers. For the above table, Joe is the only employee who earns more than his manager. + | Employee | + | Joe + | 60000 | NULL | 90000 | NULL ISQL A table Products have: a name (TEXT) a description (TEXT) a unit cost stored in cents (INTEGER) and of course we also add an id column to identify them. Separately, we'd like to track the number of items in stock for each product. To do so we'll have a store and an inventory table. Stores have just an id and a name. Then, our inventory table should combine stores and products, listing how much of each product each store has in stock. a product_id (INTEGER) a store_id (INTEGER) a quantity (INTEGER) in stock Now we can insert some stores, products and inventory into our database. There are 2 stores -- one called NY and one called NJ. There are 2 products we are concerned with. Their names are sneakers, costing $220 (remember this is dollars!) and boots costing $350. Use any description for each that you'd like. NY has 4 sneakers in stock and 3 boots. NJ has 5 sneakers in stock and no boots. Insert the above data into the tables you have created.sqlList all students WHO have reserve a Book with theme drama
- Write the following SQL Statements: Write a SELECT statement that returns one row for each customer that has orders with these columns: The email_address from the Customers table A count of the number of orders The total amount for each order (Hint: First, subtract the discount amount from the price. Then, multiply by the quantity.) Return only those rows where the customer has more than 1 order. Sort the result set in descending sequence by the sum of the line item amounts. Write a SELECT statement that answers this question: What is the total amount ordered for each product? Return these columns: The product name from the Products table The total amount for each product in the Order_Items (Hint: You can calculate the total amount by subtracting the discount amount from the item price and then multiplying it by the quantity) Use the ROLLUP operator to include a row that gives the grand total.
