maby AE is Right... C. CEIL returns the largest integer less than or equal to a specified number. Can change : CEIL returns the minmum integer more than or equal to a specified number

Based on Oracle's definitions, even though they do not make sense. Since when common sense is common practice? Anyhow for test purposes. According to that information I believe the correct answers are ABE. Although you can only choose 2. Oracle's Definition of CEIL: CEIL returns the smallest integer that is greater than or equal to n. ( https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/CEIL.html#GUID-6DCC9AFB-9B80-4C27-AF63-5AA3B1E43660 ) C is incorrect as it says: CEIL returns the largest integer less than or equal to a specific number. This is the definition of FLOOR ( https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/FLOOR.html#GUID-67F61AC7-C097-4397-A122-213157BF584F ) E: LAST_DAY ( https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/LAST_DAY.html#GUID-296C7C02-7FB9-4AAC-8927-6A79320CE0C6 )

B also could an answer as if you execute select ceil('abc') from dual; you get ORA-017222: invalid number. Making this even more confusing.

AE is the correct answer. SELECT LAST_DAY(TO_DATE('09-SEP-2023')) FROM DUAL; //op- 30-09-2023 SELECT CEIL('100'.2) FROM DUAL; //op 101 select add_months(TO_DATE('25-DEC-2023'),3) from dual; //op 25-03-2024

A and E are the correct answers. A - ADD_MONTHS returns the date date plus integer months. (https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/ADD_MONTHS.html#GUID-B8C74443-DF32-4B7C-857F-28D557381543) E - LAST_DAY returns the date of the last day of the month that contains date. The return type is always DATE, regardless of the datatype of date. (https://docs.oracle.com/cd/B19306_01/server.102/b14200/functions072.htm)

C. CEIL returns the largest integer less than or equal to a specified number. How does Option:C is correct. CEIL always return greater than or equal to specified number.

The two true statements are: AE Explanation: B. CEIL is an Oracle SQL function that requires an argument which is a numeric data type. This statement is false, as CEIL can also take input arguments of type DATE or TIMESTAMP. C. CEIL is an Oracle SQL function that returns the smallest integer greater than or equal to a specified number. This statement is false, as CEIL actually returns the largest integer less than or equal to a specified number. D. LAST_DAY is an Oracle SQL function that returns the date of the last day of the current month only. This statement is false, as LAST_DAY can be used with any date argument to return the last day of that month. E. This statement is true. LAST_DAY is an Oracle SQL function that can be used with a date argument to return the date of the last day of the month for that date. For example, LAST_DAY('2023-06-26') would return '2023-06-30'. F. This statement is false. LAST_DAY can be used with any date argument to return the last day of that month, not just the previous month.

AE is correct, C is false CEIL return SMALL NOT LARGEST https://docs.oracle.com/en/database/oracle/oracle-database/21/sqlrf/CEIL.html#GUID-6DCC9AFB-9B80-4C27-AF63-5AA3B1E43660

por sure AE are correct. C cannot be correct by "CEIL returns the largest integer...". Correct answer should be "CEIL returns the smallest integer..."

C is the definition of FLOOR()!

I think that these are correct: A, B, E. C is wrong because CEIL returns the smallest integer that is greater than or equal to the specified number

C is wrong because CEIL returns the smallest integer greater than or equal to a specified number. https://docs.oracle.com/database/121/SQLRF/functions025.htm#SQLRF00614 E is good Because select last_day(('01-FEB-2023')) as "xxxgg" from dual; Answer : 2/28/2023 Finally the answer is AE

Why B is not correct ?? It is true the CIEL_FUNCTION() requires a numeric data type. I do not understand why it is being ignored! please refer to this source: https://www.w3resource.com/sql/arithmetic-functions/ceil-with-positive-value.php

I understand why it is A and C. I do not understand why D is not correct??

Answer: A, E "CEIL returns smallest integer greater than or equal to n. and can use any numeric or nonnumeric data type that can be implicit converted to numeric adta type" https://docs.oracle.com/database/121/SQLRF/functions025.htm#SQLRF00614

A, E may be right. As per option C, Ceil returns the lesser integer compared to the argument provided. last_day('date') provides the last day of whatever date is provided as argument.
