Oracle Database SQL Sample Questions (Q107-Q112):

NEW QUESTION # 107
Which three are true about privileges and roles?

A. System privileges always set privileges for an entire database.
B. A user has all object privileges for every object in their schema by default.
C. PUBLIC acts as a default role granted to every user in a database.
D. All roles are owned by the SYS schema.
E. PUBLIC can be revoked from a user.
F. A role can contain a combination of several privileges and roles.
G. A role is owned by the user who created it.

Answer: B,C,F

NEW QUESTION # 108
In the PROMOTIONS table, the PROMO_BEGTN_DATE column is of data type DATE and the default date format is DD-MON-RR.
Which two statements are true about expressions using PROMO_BEGIN_DATE contained in a query?

A. TO_DATE(PROMO_BEGIN_DATE * 5) will return a date
B. PROMO_BEGIN_DATE-5 will return a date.
C. PROMO_BEGIN_DATE-SYSDATE will return an error.
D. TO_NUMBER(PROMO_BEGIN_DATE)-5 will return number
E. PROMO_BEGIN_DATE-SYSDATE will return a number.

Answer: B,E

Explanation:
A . This statement is incorrect because TO_NUMBER expects a character string as an argument, not a date. Directly converting a date to a number without an intermediate conversion to a character string would result in an error. B. This statement is incorrect. Multiplying a date by a number does not make sense in SQL, and attempting to convert such an expression to a date will also result in an error. C. This statement is correct. Subtracting two dates in Oracle SQL results in the number of days between those dates, hence the result is a number. D. This statement is correct. Subtracting a number from a date in Oracle SQL will subtract that number of days from the date, returning another date. E. This statement is incorrect. As stated in C, subtracting a date from SYSDATE correctly returns the number of days between those two dates, not an error.
These concepts are explained in the Oracle Database SQL Language Reference, which details date arithmetic in SQL.
