問題 #97
Examine the description of the PROMOTIONS TABLE:
You want to display the unique is promotion costs in each promotion category.
Which two queries can be used?
- A. SELECT DISTINCT promo_cost ||'in'IIDISTINCT promo_category promotions ORDER BY1:
- B. select DISTINCT promo_categoryIl 'has'||promol_cost as COSTS FROM promotions ORDER BY 1:
- C. SELECT promo_category, DISTINCT promo_cost FROM promotiong ORDER BY 2:
- D. SELECT DISTINCT promo_category, promo_cost FROM promotions ORDER BY 1;
- E. SELECT promo_cost, promo_category FROM promotions ORDER BY 1
答案：B,D
解題說明：
For displaying unique promotion costs in each promotion category from the PROMOTIONS table:
* A: SELECT DISTINCT promo_category, promo_cost FROM promotions ORDER BY 1: This query correctly retrieves unique combinations of promo_category and promo_cost, sorting the results based on the promo_category.
* D: SELECT DISTINCT promo_category || ' has ' || promo_cost AS COSTS FROM promotions ORDER BY 1: This query correctly combines the category and cost into a single string for each unique combination, using string concatenation and the DISTINCT keyword to ensure uniqueness, sorting by the concatenated string.
Incorrect options:
* B: This does not ensure that the combinations of promo_cost and promo_category are unique because DISTINCT was not specified for both columns together.
* C: The syntax is incorrect; DISTINCT cannot be applied to a single column partway through a SELECT clause.
* E: This is syntactically incorrect as DISTINCT cannot be used twice in the way shown; it must apply to all columns if used at the beginning of a SELECT statement.
問題 #98
Evaluate the following CREATE TABLE commands:
CREATE_TABLE orders
(ord_no NUMBER (2) CONSTRAINT ord_pk PRIMARY KEY,
ord_date DATE,
cust_id NUMBER (4) );
CREATE TABLE ord_items
(ord _no NUMBER (2),
item_no NUMBER(3),
qty NUMBER (3) CHECK (qty BETWEEEN 100 AND 200),
expiry_date date CHECK (expiry_date> SYSDATE),
CONSTRAINT it_pk PRIMARY KEY (ord_no, item_no),
CONSTARAINT ord_fk FOREIGN KEY (ord_no) REFERENCES orders (ord_no) );
The above command fails when executed. What could be the reason?
- A. The CHECK constraint cannot be placed on columns having the DATE data type.
- B. The BETWEEN clause cannot be used for the CHECK constraint.
- C. ORD_NO and ITEM_NO cannot be used as a composite primary key because ORD_NO is also the FOREIGN KEY.
- D. SYSDATE cannot be used with the CHECK constraint.
答案：D
問題 #99
Which statement fails to execute successfully?
答案：D
解題說明：
In Oracle SQL, when performing a JOIN operation, the ON clause is used to specify the condition that relates the two tables being joined. The WHERE clause can be used to further filter the result set.
A) This is a valid join condition using the WHERE clause to filter the rows after the join has been made.
B) This statement will fail because the ON clause should only contain conditions that relate the two tables. The condition for filtering the departments table should be in the WHERE clause, not in the ON clause. This is a common mistake when writing JOIN statements.
C) This is a correct statement. The ON clause specifies how the tables are related and the WHERE clause specifies an additional filtering condition for the query.
D) This statement is also correct. It's similar to the first statement (A) and properly places the department_id filter in the ON clause, which is acceptable though not typically best practice as it can be less readable than using a WHERE clause for non-join conditions.
When the JOIN operation is executed, the database first pairs rows from the joined tables that meet the join condition specified by the ON clause. Then, it filters the result of the JOIN operation based on the condition specified in the WHERE clause.

問題 #100
Examine the structure of the PROGRAMS table:
Which two SQL statements would execute successfully?
- A. SELECT NVL (ADD_MONTHS (END_DATE,1) SYSDATE) FROM programs;
- B. SELECT TO_DATE (NVL (SYSDATE-END_DATE, SYSDATE)) FROM programs;
- C. SELECT NVL (TO_CHAR (MONTHS_BETWEEN (start-date, end_date)), 'Ongoing') FROM programs
- D. SELECT NVL (MONTHS_BETWEEN (start_date, end_date), 'Ongoing') FROM programs;
答案：A,C
問題 #101
View the Exhibit and examine the structure of the ORDER_ITEMS table.
Examine the following SQL statement:
SELECT order_id, product_id, unit_price
FROM order_items
WHERE unit_price
(SELECT MAX(unit_price)
FROM order_items
GROUP BY order_id);
You want to display the PRODUCT_ID of the product that has the highest
UNIT_PRICE per ORDER_ID. What correction should be made in the above SQL statement to achieve this?
- A. Remove the GROUP BY clause from the subquery and place it in the main query
- B. Replace = with the IN operator
- C. Replace = with the >ANY operator
- D. Replace = with the >ALL operator
答案：B
