Oracle Database SQL Sample Questions (Q132-Q137):

NEW QUESTION # 132
Refer to the exhibit.

For each employee in department 90 you want to display:
1. their last name
2. the number of complete weeks they have been employed
The output must be sorted by the number of weeks, starting with the longest serving employee first.Which statement will accomplish this?

A. SELECT last_name, TRUNC( (SYSDATE - hire_ date) 1 7) AS tenure
FROM employees
WHERE department_ id = 90
ORDER BY tenure ;
B. SELECT last_name, TRUNC ( (SYSDATE - - hire_ date) 1 7) AS tenure
FROM employees
WHERE department_id = 90
ORDER BY tenure DESC;
C. SELECT last_name, ROUND( (SYSDATE - hire_ date) 17) AS tenure
FROM employees
WHERE department_ id = 90
ORDER BY tenure DESC;
D. SELECT last_name, ROUND( (SYSDATE - hire_ date) 1 7) AS tenure
FROM employees
WHERE department_ id = 90
ORDER BY tenure ;

Answer: B

Explanation:
D . True. The TRUNC function, when applied to the difference between SYSDATE and hire_date divided by 7, will return the number of complete weeks of employment. The ORDER BY tenure DESC will sort the result in descending order, starting with the longest-serving employee.
A is incorrect because it does not include the DESC keyword necessary to start with the longest-serving employee. B is incorrect because ROUND could result in rounding up to the next week, which does not give the number of complete weeks. C is incorrect because the division is done by 17 instead of 7, which is likely a typo, and ROUND is used instead of TRUNC.
