QUESTION 198
Examine the commands used to create DEPARTMENT_DETAILSand COURSE_DETAILS tables:

You want to generate a list of all department IDs that do not exist in the COURSE_DETAILStable.
You execute the SQL statement:

What is the outcome?

It fails because the join type used is incorrect.

It executes successfully and displays the required list.

It executes successfully but displays an incorrect list.

It fails because the ON clause condition is not valid.

QUESTION 199
Examine the business rule:
Each student can work on multiple projects and each project can have multiple students.
You need to design an Entity Relationship Model (ERD) for optimal data storage and allow for generating reports in this format:
STUDENT_ID FIRST_NAME LAST_NAME PROJECT_ID PROJECT_NAME PROJECT_TASK
Which two statements are true in this scenario?

The ERD must have a 1:M relationship between the STUDENTSand PROJECTSentities.

The ERD must have a M:M relationship between the STUDENTSand PROJECTSentities that must be resolved into 1:M relationships.

STUDENT_IDmust be the primary key in the STUDENTSentity and foreign key in the PROJECTSentity.

PROJECT_IDmust be the primary key in the PROJECTSentity and foreign key in the STUDENTSentity.

An associative table must be created with a composite key of STUDENT_ID and PROJECT_ID, which is the foreign key linked to the STUDENTS and PROJECTS entities.

QUESTION 200
You execute this command:
TRUNCATE TABLE dept;
Which two are true?

It drops any triggers defined on the table.

It retains the indexes defined on the table.

It retains the integrity constraints defined on the table.

A ROLLBACK statement can be used to retrieve the deleted data.

It always retains the space used by the removed rows.

A FLASHBACK TABLE statement can be used to retrieve the deleted data.

When using the TRUNCATE TABLE command in Oracle, several aspects of the table’s structure and associated database objects are impacted. Here’s an explanation of each option:
* A: Incorrect. TRUNCATE TABLE does not drop triggers associated with the table; they remain defined.
* B: Correct. Indexes on the table are retained and not dropped when you truncate a table. However, if the index is a domain index, it may be dropped depending on its type.
* C: Correct. Integrity constraints such as primary keys, foreign keys, etc., are retained unless they are on a disabled state where truncation can lead to constraint being dropped.
* D: Incorrect. A TRUNCATE TABLE operation cannot be rolled back. It is a DDL (Data Definition Language) operation and commits automatically.
* E: Incorrect. The TRUNCATE TABLE operation deallocates the space used by the data unless the REUSE STORAGE clause is specified.
* F: Incorrect. TRUNCATE TABLE operation removes all the rows in a table and does not log individual row deletions, thus FLASHBACK TABLE cannot be used to retrieve the data.

QUESTION 201
Using the CUSTOMERStable, you need to generate a report that shows 50% of each credit amount in each income level. The report should NOT show any repeated credit amounts in each income level.
Which query would give the required result?

SELECT cust_income_level || ‘ ‘ || cust_credit_limit * 0.50 AS “50% Credit Limit” FROM customers.

SELECT DISTINCT cust_income_level || ‘ ‘ || cust_credit_limit * 0.50 AS “50% Credit Limit” FROM customers.

SELECT DISTINCT cust_income_level, DISTINCT cust_credit_limit * 0.50 AS “50% Credit Limit” FROM customers.

SELECT cust_income_level, DISTINCT cust_credit_limit * 0.50 AS “50% Credit Limit” FROM customers

QUESTION 202
Examine this description of the PRODUCTStable:

Rows exist in this table with data in all the columns. You put the PRODUCTStable in read-only mode.
Which three commands execute successfully on PRODUCTS? (Choose three.)

DROP TABLE products;

ALTER TABLE products DROP COLUMN expiry_date;

ALTER TABLE products SET UNUSED (expiry_date);

ALTER TABLE products DROP UNUSED COLUMNS;

CREATE INDEX price_idx ON products (price);

TRUNCATE TABLE products;

QUESTION 203
View the Exhibit and examine the data in EMP and DEPT tables.

In the DEPT table, DEPTNO is the PRIMARY KEY.
In the EMP table, EMPNO is the PRIMARY KEY and DEPTNO is the FOREIGN KEY referencing the DEPTNO column in the DEPT table.
What would be the outcome of the following statements executed in the given sequence?
DROP TABLE emp;
FLASHBACK TABLE emp TO BEFORE DROP;
INSERT INTO emp VALUES (2, ‘SCOTT’, 10);
INSERT INTO emp VALUES (3, ‘KING’, 55);

Both the INSERT statements would fail because the constraints are automatically retrieved when the table is flashed back.

Both the INSERT statements would succeed because none of the constraints on the table are automatically retrieved when the table is flashed back.

Only the first INSERT statement would succeed because all constraints except the primary key constraint are automatically retrieved after a table is flashed back.

Only the SECOND INSERT statement would succeed because all the constraints except referential integrity constraints that reference other tables are retrieved automatically after the table is flashed back.

QUESTION 204
View the Exhibits and examine PRODUCTSand SALES tables.
Exhibit 1

Exhibit 2

You issue the following query to display product name the number of times the product has been sold:

What happens when the above statement is executed?

The statement executes successfully and produces the required output.

The statement produces an error because a subquery in the FROM clause and outer-joins cannot be used together.

The statement produces an error because the GROUP BY clause cannot be used in a subquery in the clause.
FROM

The statement produces an error because ITEM_CNT cannot be displayed in the outer query.

QUESTION 205

You must display the maximum and minimum salaries of employees hired 1 year ago.
Which two statements would provide the correct output? (Choose two.)

SELECT MIN(Salary) minsal, MAX(salary) maxsalFROM employeesWHERE hire_date < SYSDATE-365GROUP BY MIN(salary), MAX(salary);

SELECT minsal, maxsalFROM (SELECT MIN(salary) minsal, MAX(salary) maxsalFROM employeesWHERE hire_date < SYSDATE-365)GROUP BY maxsal, minsal;

SELECT minsal, maxsalFROM (SELECT MIN(salary) minsal, MAX(salary) maxsalFROM employeesWHERE hire_date < SYSDATE-365GROUP BY MIN(salary), MAX(salary));

SELECT MIN(Salary), MAX(salary)FROM (SELECT salary FROMemployeesWHERE hire_date < SYSDATE-365);

QUESTION 206
Examine the description of the SALES1 table:

SALES2 is a table with the same description as SALES1.
Some sales data is duplicated in both tables.
You want to display the rows from the SALES1 table which are not present in the SALES2 table.
Which set operator generates the required output?

SUBTRACT

INTERSECT

UNION ALL

UNION

MINUS

SET (job_id, salary) =
(SELECT job_id, salary
FROM employees
WHERE employee_id = 200)
WHERE employee id=100;
Which two statements are true?

Employees 100 and 200 will have the same SALARY as before the update command.

Employee 100 will have SALARY set to the same value as the SALARY of employee 200.

Employee 100 will have JOB_ID set to the same value as the JOB_ID of employee 200.

Employees 100 and 200 will have the same JOB ID as before the update command.

Employee 200 will have SALARY set to the same value as the SALARY of employee 100.

Employee 200 will have JOB_ID set to the same value as the JOB_ID of employee 100

QUESTION 208
Examine the structure of the EMPLOYEES table.

You must display the details of employees who have manager with MANAGER_ID 100, who were hired in the past 6 months and who have salaries greater than 10000.
Which query would retrieve the required result?

SELECT last_name, hire_date, salaryFROM employeesWHERE salary > 10000UNION ALLSELECT last_name, hire_date, salaryFROM employeesWHERE manager_ID = (SELECT employee_id FROM employees WHERE employee_id = 100)INTERSECTSELECT last_name, hire_date, salaryFROM employeesWHERE hire_date > SYSDATE-180;

SELECT last_name, hire_date, salaryFROM employeesWHERE manager_id = (SELECT employee_id FROM employees WHERE employee_id = 100)UNION ALL(SELECT last_name, hire_date, salaryFROM employeesWHERE hire_date > SYSDATE-180INTERSECTSELECT last_name, hire_date, salaryFROM employeesWHERE salary > 10000);

SELECT last_name, hire_date, salaryFROM employeesWHERE manager_id = (SELECT employee_id FROM employees WHERE employee_id = ‘100’)UNIONSELECT last_name, hire_date, salaryFROM employeesWHERE hire_date > SYSDATE-180INTERSECTSELECT last_name, hire_date, salaryFROM employeesWHERE salary > 10000;

(SELECT last_name, hire_date, salaryFROM employeesWHERE salary > 10000UNION ALLSELECT last_name, hire_date, salaryFROM employeesWHERE manager_ID = (SELECT employee_id FROM employees WHERE employee_id = 100))UNIONSELECT last_name, hire_date, salaryFROM employeesWHERE hire_date > SYSDATE-180;
