Oracle Database SQL Sample Questions (Q41-Q46):

NEW QUESTION # 41
Examine this statement:
SELECT last name
FROM employees
ORDER BY CASE WHEN salary = (SELECT MAX(salary) FROM employees)
THEN 'A'
ELSE last_ name
END ,last_name DESC;
Which two statements are true?

  • A. All remaining employee names will appear in descending order.
  • B. The names of employees earning the maximum salary will appear first in descending order.
  • C. The names of employees earning the maximum salary will appear first In ascending order.
  • D. All remaining employee names will appear in ascending order.
  • E. The names of employees earning the maximum salary will appear first in an unspecified order.
  • F. All remaining employee names will appear in an unspecified order.

Answer: A,C

Explanation:
The ORDER BY clause with a CASE statement allows for conditional sorting based on the results of the CASE expression.
A . This is not true, as the 'A' in the THEN clause would cause the employees earning the maximum salary to be sorted at the top, but it does not determine the order in which their last names would appear.
B . This is true, the 'A' in the THEN clause will result in all maximum salary earners to be sorted at the top, and since 'A' comes before any last names alphabetically, they will be in ascending order.
C . This is not true, as the ELSE clause sorts the remaining employees by last_name but does not specify an order; hence, it defaults to ascending which contradicts the second part of the ORDER BY clause which specifies DESC.
D . This is not true, as the order of the remaining employee names is specified by the ORDER BY clause, which states last_name DESC.
E . This is true, after the employees with the maximum salary are sorted, the remaining employees' names will appear in descending order due to the last_name DESC in the ORDER BY clause.
F . This statement is not true as the specified 'A' in the CASE statement provides a definite order for employees earning the maximum salary.

  • C. When a database instance shuts down abnormally, sequence numbers that have been cached but not used are available again when the instance is restarted.

NEW QUESTION # 43
View the Exhibit and examine the structure of the CUSTOMERS table.

Evaluate the following SQL statement:

Which statement is true regarding the outcome of the above query?

  • A. It executes successfully.
  • B. It returns an error because the BETWEEN operator cannot be used in the HAVING clause.
  • C. It returns an error because WHERE and HAVING clauses cannot be used to apply conditions on the same column.

Answer: A


NEW QUESTION # 44

FROM employees
WHERE department_id= 50 ORDER BY department_id
UNION
SELECT employee_id, department_id
FROM employees
WHERE department_id= 90
UNION
SELECT employee_id, department_id
FROM employees
WHERE department_id= 10;
What would be the outcome of the above SQL statement?

  • A. The statement would not execute because the positional notation instead of the column name should be used with the ORDER BY clause.
  • B. The statement would execute successfully but it will ignore the ORDER BY clause and display the rows in random order.
  • C. The statement would not execute because the ORDER BY clause should appear only at the end of the SQL statement, that is, in the last SELECT statement.
  • D. The statement would execute successfully and display all the rows in the ascending order of DEPARTMENT_ID.

Answer: C
