Modify the query in Problem 13 to include the number of individual product purchases made by each customer. (In other words, if the customer’s invoice is based on three products, one per LINE_NUMBER, you count three product purchases. Note that in the original invoice data, customer 10011 generated three invoices, which contained a total of six lines, each representing a product purchase.) Your output values must match those shown in Figure P7.14, sorted by customer code.
Write a query to display the patron ID, first and last name of all patrons that have never checked out any book. Sort the result by patron last name and then first name. (See the figure below for the output) Write a query to display the patron ID and the average number of days that patron keeps books during a checkout. Limit the results to only patrons who have at least three checkouts.  Sort the results in descending order by the average days the book is kept. (See the figure below for the output)
3.) Find the goalkeepers of teams that played more than four games. List the surname of the goalkeeper, the team, and the number of minutes the goalkeeper played. 4) How many players who play on a team with ranking<10played more than 350 minutes? Return one number in a column named 'superstar'. 5) What is the average number of passes made by forwards? By midfielders? Write one query that gives both values with the corresponding position. 6) Which team has the highest average number of passes per minute played? Return the team and average passes per minute. Hints: (1) You can compute a team's average number of passes per minute played by dividing the total number of passes by the total number of minutes. To force floating point division, multiply one operand by 1.0. (2) Consider using Limit.
