Oracle Database SQL Sample Questions (Q206-Q211):

NEW QUESTION # 206
In your session, the NLS._DAE_FORMAT is DD- MM- YYYY.There are 86400 seconds in a day.Examine this result:
DATE
02-JAN-2020
Which statement returns this?

  • A. SELECT To CHAR(TO _DATE('29-10-2019') + INTERVAL '2' NONTH + INTERVAL '5' DAY INEERVAL '120' SECOND, ' DD-MON-YYY) AS "date" FROM DUAL;
  • B. SELECT-TO_CHAR(TO _DATE('29-10-2019'+ INTERVAL '2' MONTH+INTERVAL '6' DAYINTERVAL
    '120' SECOND, 'DD-MON-YY') AS "daTe"
    FROM DUAL;
  • C. SELECT TO_ CHAR(TO_ DATE('29-10-2019') + INTERVAL '3' MONTH + INTERVAL '7' DAY - INTERVAL '360' SECOND, ' DD-MON-YYYY') AS "date" FROM DUAL;
  • D. SELECT-TO_CHAR(TO _DATE('29-10-2019'+ INTERVAL '2' MONTH+INTERVAL '4' DAYINTERVAL
    '120' SECOND, 'DD-MON-YY') AS "daTe"
    FROM DUAL;
  • E. SELECT TO_ CHAR(TO_ DATE('29-10-2019') +INTERVAL '2'; MONTH + INTERVAL '5'; DAY - INTERVAL '86410' SECOND, ' DD-MON-YYYY') AS "date" FROM DUAL;

Answer: C

Explanation:
To calculate the date from a given base date with intervals, Oracle allows you to add or subtract intervals from dates. Since the NLS_DATE_FORMAT is set to DD-MM-YYYY, the output is expected to be in that format.
Option B seems to calculate a date that is 3 months and 7 days ahead of October 29, 2019, and then subtracts 360 seconds (which is 6 minutes), resulting in a time that is still within the same day.
Here's how the calculation in option B would work out:
Start date: 29-10-2019
Add 3 months: 29-01-2020
Add 7 days: 05-02-2020
Subtract 360 seconds: Since it's only a few minutes, the date remains 05-02-2020.
However, this does not match the provided result of 02-JAN-2020. We would need to consider the exact amount of time being subtracted or added to find the correct answer.
But upon reviewing the options, they all have various syntax errors such as a missing TO_CHAR function, incorrect quotes, and date formats not matching the session's NLS_DATE_FORMAT. Therefore, we would need to correct these issues to find the right answer.
