*Important – Do Not Use the Query Wizard as these are exercises in learning to write SQL.  It will be apparent in the syntax if you completed the assignment with the Query Wizard.  Please practice honesty and integrity as you complete the assignment.

#1)  Number of Orders with Credit Card Payment

Write a SQL statement that will count the number of orders in the [Order Details] table that were paid by credit card.

Example:

FROM [table]

WHERE [field] = “value”

GROUP BY [field]

#2)  Top Selling Product based on Order Amount (One Join)

Write a SQL statement that will join the [Order Details ] table and [Products] table to determine the top selling product based on [Quantity]*[Unit Price].

Example:

SELECT B.[field], sum(A.[field]*A.[field]) as Orders

FROM ( [table] A

INNER JOIN [table] B

on A.[field] = B.[field] )

GROUP BY B.[field]

ORDER BY sum(A.[field] *A.[field] ) desc

#3)  Products with Less Than \$2500 in Orders

Write a SQL statement that will join the [Order Details] table and [Products] table to determine only those products with less than \$2500 in Orders based on [Quantity]*[Unit Price].

Example:

SELECT B.[field], sum(A.[field] * A.[field]) as Orders

FROM ([table] A

INNER JOIN [table] B

on A.[field] = B.[field])

GROUP BY B.[field]

HAVING sum(A.[field]*A.[field]) value

ORDER BY sum(A.[field] *A.[field]) desc

#4) Top Producing Employee base on Order Amount (Two Joins)

Write a SQL statement that will join the [Orders] table, [Order Details] table and [Employees] table to determine the highest producing employee based on the employees first name and [Quantity]*[Unit Price].

FROM (([table] A

INNER JOIN [table] B

on A.[field] = B.[field])

INNER JOIN [table] C

on B.[field] = C.[field])

GROUP BY C.[field]

ORDER BY sum(A.[field] *A.[field] ) desc
