NEW QUESTION 139
Examine the ORDER _ITEms table:

Which two queries return rows where QUANTITY is a multiple of ten?

SELECT * FROM order_ items WHERE quantity = TRUNC (quantity, -1);

SELECT * FROM order_ items WHERE MOD (quantity, 10) = 0;

SELECT” FROM order_ items WHERE FLOOR (quantity / 10) = TRUNC (quantity / 10);

SELECT FROM order_ items WHERE quantity / 10 = TRUNC (quantity);

SELECT” FROM order_ _items WHERE quantity = ROUND (quantity, 1);

A: This statement will not work because TRUNC(quantity, -1) will truncate the quantity to zero decimal places when the number is a negative power of ten, which does not guarantee that the quantity is a multiple of ten.
B: This statement is correct. The MOD function returns the remainder of a division. If MOD(quantity, 10) equals zero, it means that quantity is a multiple of ten.
C: This statement is correct. FLOOR(quantity / 10) equals TRUNC(quantity / 10) when quantity is an exact multiple of ten, as FLOOR returns the largest integer less than or equal to a number, and TRUNC will truncate the decimal part.
D: This statement is incorrect because TRUNC(quantity) would remove any decimal places from quantity, and comparing it to quantity / 10 will not guarantee that the quantity is a multiple of ten.
E: This statement is incorrect. ROUND(quantity, 1) will round the quantity to one decimal place, not check if it’s a multiple of ten.

NEW QUESTION 140
You execute this query:

What is the result?

NEW QUESTION 141
Examine the description of the PRODUCT_STATUS table:

The STATUS column contains the values ‘IN STOCK’ or ‘OUT OF STOCK’ for each row.
Which two queries will execute successfully?

Option A

Option B

Option C

Option D

Option E

Option F

NEW QUESTION 142
View the Exhibit and examine the structure of the PRODUCT table.

Which two tasks would require subqueries? (Choose two.)

display all products whose PROD_MIN_PRICE is more than the average PROD_LIST_PRICE of all products, and whose status is orderable

display the total number of products supplied by supplier 102 and have product status as ‘OBSOLETE’

display the number of products whose PROD_LIST_PRICE is more than the average PROD_LIST_PRICE.

display suppliers whose PROD_LIST_PRICE is less than 1000

display the minimum PROD_LIST_PRICE for each product status

NEW QUESTION 143
You need to calculate the number of days from 1st January 2019 until today.
Dates are stored in the default format of DD-MON-RR.
Which two queries give the required output?

SELECT SYSDATE-TO_DATE (’01-JANUARY-2019′) FROM DUAL;

SELECT TO_DATE (SYSDATE, ‘DD/MONTH/YYYY’)-’01/JANUARY/2019′ FROM DUAL;

SELECT ROUND (SYSDATE-TO_DATE (’01/JANUARY/2019′)) FROM DUAL;

SELECT TO_CHAR (SYSDATE, ‘DD-MON-YYYY’)-’01-JAN-2019′ FROM DUAL;

SELECT ROUND (SYSDATE- ’01-JAN-2019′) FROM DUAL:

To calculate the number of days between two dates in Oracle SQL, you can simply subtract the earlier date from the later date, and Oracle will return the number of days between them.
Option A uses SYSDATE to get the current date and TO_DATE to convert the string ’01-JANUARY-2019′ to a date using the default date format, which matches ‘DD-MON-RR’. The subtraction here will correctly give the number of days between these two dates.
Option C is similar to A but includes the ROUND function, which is used to round the number to the nearest whole number. Since the difference between two dates in Oracle SQL is a decimal value representing the number of days and fractional days, rounding will give us the whole number of days, which is what we want.
Options B, D, and E are incorrect because they either use an invalid date format (the default format is
‘DD-MON-RR’, not ‘DD/MONTH/YYYY’ or ‘DD-MON-YYYY’), perform invalid operations (such as subtracting a string from a date), or misuse SYSDATE.

NEW QUESTION 144
Which three statements are true about Data Manipulation Language (DML)?

delete statements can remove multiple rows based on multiple conditions.

insert statements can insert nulls explicitly into a column.

insert into. . .select. . .from statements automatically commit.

DML statements require a primary key be defined on a table.

update statements can have different subqueries to specify the values for each updated column.

Data Manipulation Language (DML) operations in Oracle 12c are critical for handling data within tables.
Here’s the validity of each statement based on Oracle SQL documentation:
* Option A: True. The DELETE statement can remove multiple rows from a table and supports the use of multiple conditions in the WHERE clause to specify which rows should be removed. This allows for flexibility in managing data deletion based on various criteria.
* Option B: True. The INSERT statement can explicitly insert NULL values into a column, assuming there are no constraints (like NOT NULL) preventing such entries. This is useful for representing the absence of data or when data is unknown.
* Option C: False. DML statements like INSERT INTO…SELECT…FROM do not automatically commit in Oracle. Transactions in Oracle require explicit COMMIT commands to finalize changes, unless in an autocommit mode set by a client tool or environment, which is generally not the default behavior for server-side operations.
* Option D: False. DML statements do not require a primary key to be defined on a table. While having a primary key is a best practice for identifying each row uniquely, it’s not a prerequisite for performing DML operations like INSERT, UPDATE, or DELETE.
* Option E: True. The UPDATE statement can include different subqueries within the SET clause to determine the values for each column being updated. This allows for complex calculations and data retrieval to be part of an update, increasing the power and flexibility of data modification.

NEW QUESTION 145
View the exhibit and examine the descriptions of the DEPT and LOCATIONS tables.

You want to update the CITY column of the DEPT table for all the rows with the corresponding value in the CITY column of the LOCATIONS table for each department.
Which SQL statement would you execute to accomplish the task?

UPDATE dept dSET city = ALL (SELECT cityFROM locations lWHERE d.location_id = l.location_id);

UPDATE dept dSET city = (SELECT cityFROM locations l)WHERE d.location_id = l.location_id;

UPDATE dept dSET city = ANY (SELECT cityFROM locations l)

UPDATE dept dSET city = (SELECT cityFROM locations lWHERE d.location_id = l.location_id);

NEW QUESTION 146
View the Exhibit and examine the structure of ORDERS and CUSTOMERS tables. (Choose the best answer.)

You executed this UPDATE statement:
UPDATE
( SELECT order_date, order_total, customer_id FROM orders)
Set order_date = ’22-mar-2007′
WHERE customer_id IN
(SELECT customer_id FROM customers
WHERE cust_last_name = ‘Roberts’ AND credit_limit = 600);
Which statement is true regarding the execution?

It would not execute because a subquery cannot be used in the WHERE clause of an UPDATE statement.

It would not execute because two tables cannot be referenced in a single UPDATE statement.

It would execute and restrict modifications to the columns specified in the SELECT statement.

It would not execute because a SELECT statement cannot be used in place of a table name.

NEW QUESTION 147
View the Exhibit and examine the data in the PROMOTIONStable.

PROMO_BEGIN_DATEis stored in the default date format, dd-mon-rr.
You need to produce a report that provides the name, cost, and start date of all promos in the POST category that were launched before January 1, 2000.
Which SQL statement would you use?
SELECT promo_name, promo_cost, promo_begin_date

FROM promotions
WHERE promo_category = ‘post’ AND promo_begin_date < ’01-01-00′;
SELECT promo_name, promo_cost, promo_begin_date

FROM promotions
WHERE promo_category LIKE ‘P%’ AND promo_begin_date < ‘1-JANUARY-00’;
SELECT promo_name, promo_cost, promo_begin_date

FROM promotions
WHERE promo_cost LIKE ‘post%’ AND promo_begin_date < ’01-01-2000′;
SELECT promo_name, promo_cost, promo_begin_date

FROM promotions
WHERE promo_category LIKE ‘%post%’ AND promo_begin_date < ‘1-JAN-00’;

NEW QUESTION 148
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?

Remove the GROUP BY clause from the subquery and place it in the main query

Replace = with the >ANY operator

Replace = with the >ALL operator

Replace = with the IN operator

NEW QUESTION 149
Which two are true about multiple table INSERT statements?

They always use subqueries.

They can transform a row from a source table into multiple rows in a target table.

The conditional INSERT FIRST statement always inserts a row into a single table.

The conditional INSERT ALL statement inserts rows into a single table by aggregating source rows.

The unconditional INSERT ALL statement must have the same number of columns in both the source and target tables.

B: True. Multiple table insert statements, specifically the conditional INSERT ALL, can transform a single row from the source table into multiple rows in one or more target tables depending on the conditions specified in the WHEN clauses.
E: True. The unconditional INSERT ALL statement will insert rows into multiple target tables without any conditions. However, it does not require the same number of columns in both the source and target tables. The INSERT ALL syntax allows you to specify different columns for each target table into which rows will be inserted.
Multiple table insert operations allow for complex insert scenarios, where based on the data, one can insert into different tables or multiple times into the same table based on different conditions.
Reference:
Oracle SQL reference details the use of INSERT ALL and INSERT FIRST clauses for inserting into multiple tables based on conditions specified.

NEW QUESTION 150
Examine the structure of the CUSTOMERS table: (Choose two.)

CUSTNO is the PRIMARY KEY.
You must determine if any customers’ details have been entered more than once using a different CUSTNO, by listing all duplicate names.
Which two methods can you use to get the required result?

Subquery

Self-join

Full outer-join with self-join

Left outer-join with self-join

Right outer-join with self-join

NEW QUESTION 151
View the Exhibit and examine the description of the EMPLOYEES table.

You want to calculate the total remuneration for each employee. Total remuneration is the sum of the annual salary and the percentage commission earned for a year. Only a few employees earn commission.
Which SQL statement would you execute to get the desired output?

SELECT first_name, salary, salary*12+(salary*NVL2 (commission_pct, salary,salary+commission_pct))”Total”FROM EMPLOYEES;

SELECT first_name, salary, salary*12+salary*commission_pct “Total”FROM EMPLOYEES;

SELECT first_name, salary (salary + NVL (commission_pct, 0)*salary)*12 “Total”FROM EMPLOYEES;

SELECT first_name, salary, salary*12 + NVL(salary,0)*commission_pct, “Total”FROM EMPLOYEES;

NEW QUESTION 152
Examine this SQL statement:

Which two are true? (Choose two.)

The subquery is not a correlated subquery.

The subquery is executed before the DELETEstatement is executed.

The DELETE statement executes successfully even if the subquery selects multiple rows.

The subquery is executed for every row in the EMPLOYEEStable.

All existing rows in the EMPLOYEEStable are deleted.

NEW QUESTION 153
Which two are true about the WITH GRANT OPTION clause?

The grantee must have the GRANT ANY OBJECT PRIVILEGE system privilege to use this option.

It can be used when granting privileges to roles.

It cannot be used to pass on privileges to PUBLIC by the grantee.

It can be used for system and object privileges.

It can be used to pass on privileges to other users by the grantee.

The grantee can grant the object privilege to any user in the database, with or without including this option.

NEW QUESTION 154
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?

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;

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;

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;

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;

NEW QUESTION 155
The SALES table has columns PROD_ID and QUANTITY_SOLD of data type NUMBER.
Which two queries execute successfully?

SELECT prod_id FROM sales WHERE quantity_sold > 55000 GROUP BY prod_id HAVING COUNT(*) >10;

SELECT prod_id FROM sales WHERE quantity_sold > 55000 AND COUNT(*) > 10 GROUP BY prod_id HAVING COUNT(*) >10;

SELECT COUNT (prod_id) FROM sales WHERE quantity_sold > 55000 GROUP BY prod_id;

SELECT prod_id FROM sales WHERE quantity_sold > 55000 AND COUNT(*) > 10 GROUP BY COUNT(*) >10;

SELECT COUNT(prod_id) FROM sales GROUP BY prod_id WHERE quantity_sold > 55000;

NEW QUESTION 156
Which two are true?

CONCAT joins two or more character strings together.

FLOOR returns the largest integer less than or equal to a specified number.

CONCAT joins two character strings together.

INSTR finds the offset within a string of a single character only.

INSTR finds the offset within a character string, starting from position 0.

FLOOR returns the largest positive integer less than or equal to a specified number.

The CONCAT function and FLOOR function in Oracle SQL have specific behaviors:
A . CONCAT function joins two or more character strings into one string, making this statement true.
B . FLOOR function returns the largest integer that is less than or equal to the specified number, making this statement true.
C . While CONCAT can join two strings together, this statement is incomplete as it can join more than two.
D . INSTR can find the offset of a substring within a string, not just a single character.
E . INSTR starts searching the string from position 1 in Oracle SQL, not position 0.
F . FLOOR does return the largest integer less than or equal to the specified number, but it can be any integer, not just positive ones.
