Question 262

View the exhibit and examine the structure of the STORES table.

You must display the NAME of stores along with the ADDRESS, START_DATE, PROPERTY_PRICE, and the projected property price, which is 115% of property price.
The stores displayed must have START_DATE in the range of 36 months starting from 01-Jan-2000 and above.
Which SQL statement would get the desired output?

A.SELECT name, concat(address||', '||city||', ',country) AS full_address, start_date, property_price, property_price*115/100FROM storesWHERE MONTHS_BETWEEN(start_date,'01-JAN-2000') <=36;

B.SELECT name, address||', '||city||', '||country AS full_address, start_date,property_price, property_price*115/100FROM storesWHERE MONTHS_BETWEEN(start_date,TO_DATE('01-JAN-2000','DD-MON-RRRR')) <=36;

C.SELECT name, concat(address||', '||city||', ', country) AS full_address, start_date,property_price, property_price*115/100FROM storesWHERE MONTHS_BETWEEN(start_date,TO_DATE('01-JAN-2000','DD-MON-RRRR')) <=36;

D.SELECT name, concat(address||', '||city||', ',country) AS full_address, start_date,property_price, property_price*115/100FROM storesWHERE TO_NUMBER(start_date-TO_DATE('01-JAN-2000','DD-MON-RRRR')) <=36;

Question 263

View the exhibit and examine the structure in ORDERSand ORDER_ITEMStables.

You need to create a view that displays the ORDER_ID, ORDER_DATE, and the total number of items in each order.
Which CREATEVIEWstatement would create the views successfully?

A.CREATE OR REPLACE VIEW ord_vu
AS SELECT o.order_id, o.order_date, COUNT (i.line_item_id) ||
"NO OF ITEMS"
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
WHITH CHECK OPTION;

B.CREATE OR REPLACE VIEW ord_vu
AS SELECT o.order_id, o.order_date, COUNT (i.line_item_id)
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
GROUP BY o.order_id, o.order_date;

C.CREATE OR REPLACE VIEW ord_vu
AS SELECT o.order_id, o.order_date, COUNT (i.line_item_id)
" NO OF ITEMS"
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
GROUP BY o.order_id, o.order_date;

D.CREATE OR REPLACE VIEW ord_vu (order_id, order_date)
AS SELECT o.order_id, o.order_date, COUNT (i.line_item_id)
" NO OF ITEMS"
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
GROUP BY o.order_id, o.order_date;

Question 264

View the exhibit and examine the structures of the EMPLOYEESand DEPARTMENTStables.

You want to update EMPLOYEEStable as follows:
* Update only those employees who work in Boston or Seattle (locations 2900 and 2700).
* Set department_idfor these employees to the department_idcorresponding to London (location_id
2100).
* Set the employees' salary in location_id2100 to 1.1 times the average salary of their department.
* Set the employees' commission in location_id2100 to 1.5 times the average commission of their department.
You issue the following command:

What is outcome?

A.It executes successfully and gives the desired update

B.It executes successfully but does not give the desired update

C.It generates an error because a subquery cannot have a join condition in a UPDATEstatement.

D.It generates an error because multiple columns (SALARY, COMMISSION)cannot be specified together in an UPDATEstatement.

Question 265

View the Exhibit and examine the structure of the CUSTOMERS table.

Which two tasks would require subqueries or joins to be executed in a single statement? (Choose two.)

A.listing of customers who do not have a credit limit and were born before 1980

B.finding the number of customers, in each city, whose marital status is 'married'

C.finding the average credit limit of male customers residing in 'Tokyo' or 'Sydney'
