6. Imagine that you have a client that has a UI for reviewing his many thousands of orders, 50 per page. The UI also

allows the client to limit the orders based on the current status of the order. The orders are in a database table

called [ORDERS] with a numeric, incrementing primary key named [ORDER_ID]. The table also has a column

[ORDER_STATUS] with three possible values:

• “PROCESSING”

• “COMPLETED”

• “CANCELLED”

Please write out a MS SQL statement that will output the third page of “CANCELLED” orders (the 101-150th

cancelled orders). Bear in mind that while the [ORDER_ID] values are probably sequential in the database, the

[ORDER_ID] values for the “CANCELLED” orders are not. Please note that MS SQL does not support MySQL’s

LIMIT command. Your answer should contain only SQL statements and not make use of other technologies (such

as ASP/PHP/Java/etc…) Please write your answer on the back of this sheet.

Par: 10-15 minutes

8. You have 26 constants, labeled A through Z. Let A equal 1. The other constants have values equal to the letter's

2^1 = 2. C = 3^B = 3^2 = 9, D = 4^C = 4 ^ 9 and so on.

The value for this expression: (X-A) * (X-B) * (X-C) * ... * (X-Y) * (X-Z) will

A. Fit into an Int32

B. Fit into an Int64

C. Not fit into either

Explain your answer.

Par: 5-10 minutes
