Oracle Database SQL Sample Questions (Q305-Q310):

NEW QUESTION # 305
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 DESC;
B. SELECT last_name, ROUND( (SYSDATE - hire_ date) 1 7) AS tenure
FROM employees
WHERE department_ id = 90
ORDER BY tenure ;
C. SELECT last_name, TRUNC( (SYSDATE - hire_ date) 1 7) AS tenure
FROM employees
WHERE department_ id = 90
ORDER BY tenure ;
D. SELECT last_name, ROUND( (SYSDATE - hire_ date) 17) AS tenure
FROM employees
WHERE department_ id = 90
ORDER BY tenure DESC;

Answer: A

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.

NEW QUESTION # 308
In the PROMOTIONS table, the PROMO_ BEGIN_DATE column is of data type and the default date format is DD-MON-RR Which two statements are true about expressions using PROMO_ BEGIN_DATE in a query?

A. PROMO_ BEGIN_DATE - SYSDATE will return an error
B. PROMO_ BEGIN_DATE - 5 will return a date
C. PROMO_ BEGIN_DATE - SYSDATE will return a number
D. TODATE(PROMO BEGIN_DATE *5) will return a date
E. TONUMBER (PROMO BEGIN_DATE) - 5 will return a number

Answer: B,C

Explanation:
In Oracle SQL, when you subtract a number from a date, the result is a date. When you subtract one date from another, the result is the number of days between the two dates.
* B: PROMO_BEGIN_DATE - 5 will subtract 5 days from the PROMO_BEGIN_DATE, resulting in a new date that is 5 days earlier than PROMO_BEGIN_DATE.
* C: PROMO_BEGIN_DATE - SYSDATE will return the number of days between the PROMO_BEGIN_DATE and the current date (SYSDATE).
The incorrect options are:
* A: TONUMBER(PROMO_BEGIN_DATE) - 5 will not return a number because
PROMO_BEGIN_DATE is a date, and TONUMBER is not a valid function to convert dates to numbers in Oracle.
* D: PROMO_BEGIN_DATE - SYSDATE will not return an error; it will return the number of days between the two dates as explained above.
* E: TODATE(PROMO_BEGIN_DATE * 5) will not return a date because PROMO_BEGIN_DATE
* 5 is not a valid operation in Oracle SQL as you cannot multiply a date by a number, and TODATE is not a valid function. The correct function name is TO_DATE.
