Oracle Database SQL Sample Questions (Q206-Q211):

NEW QUESTION # 206
View the Exhibits and examine the structure of the COSTS and PROMOTIONS tables.
You want to display PROD IDS whose promotion cost is less than the highest cost PROD ID in a pro motion time interval.
Examine this SQL statement:
SELECT prod id
FROM costs
WHERE promo id IN
(SELECT promo id
FROM promotions
WHERE promo_cost < ALL
(SELECT MAX (promo cost)
FROM promotions
GROUP BY (promo_end date-promo_begin_date)) );
What will be the result?

A. It gives an error because the GROUP BY clause is not valid
B. It gives an error because the ALL keyword is not valid.
C. It executes successfully and gives the required result.
D. It executes successfully but does not give the required result.

Answer: C

Explanation:
This SQL query checks for product IDs (prod_id) from the costs table where the promotion ID (promo_id) is associated with promotions whose costs are less than the maximum promotional cost of all promotions, grouped by the duration of each promotion (calculated as promo_end_date - promo_begin_date). The query is correctly written to fulfill these conditions.
* The subquery SELECT MAX(promo_cost) FROM promotions GROUP BY (promo_end_date - promo_begin_date) computes the maximum cost of promotions grouped by their duration, returning the highest cost for each distinct promotion length.
* The WHERE promo_cost < ALL (...) clause then filters out the promotions where the promo_cost is less than all of the maximum costs returned by the subquery, ensuring that only promo_ids associated with costs less than the highest cost for any promotion length are considered.
* Since this logical structure correctly implements the given requirement, the statement executes successfully and yields the correct results.

NEW QUESTION # 207
View the Exhibit and examine the details of PRODUCT_INFORMATIONtable.

You have the requirement to display PRODUCT_NAMEfrom the table where the CATEGORY_IDcolumn has values 12or 13, and the SUPPLIER_IDcolumn has the value 102088. You executed the following SQL statement:
SELECT product_name
FROM product_information
WHERE (category_id = 12 AND category_id = 13) AND supplier_id = 102088; Which statement is true regarding the execution of the query?

A. It would execute but the output would return no rows.
B. It would not execute because the same column has been used in both sides of the ANDlogical operator to form the condition.
C. It would not execute because the entire WHEREclause condition is not enclosed within the parentheses.
D. It would execute and the output would display the desired result.
