NEW QUESTION # 83
Examine this statement:
SELECT1 AS id,' John' AS first_name, NULL AS commission FROM dual
INTERSECT
SELECT 1,'John' null FROM dual ORDER BY 3;
What is returned upon execution?[
- A. An error
- B. 2 rows
- C. 0 rows
- D. 1 ROW
Answer: D
Explanation:
Regarding the provided SQL INTERSECT query:
* D. 1 ROW: The INTERSECT operation will compare the two SELECT statements and return rows that are identical between them. Both queries are designed to return the same values ('1' for the ID, 'John' for the name, and NULL for the commission), hence one row that is identical between the two datasets will be returned.
Incorrect options:
* A: Only one identical row exists between the two datasets.
* B: There is an identical row; thus, it is not zero.
* C: There is no error in the syntax or execution of the query.
NEW QUESTION # 84
Which three statements about roles are true?
- A. A single user can be assigned multiple roles.
- B. Roles are assigned to roles using the ALTER ROLE statement.
- C. Roles are assigned to users using the ALTER USER statement.
- D. Privileges are assigned to a role using the GRANT statement.
- E. Privileges are assigned to a role using the ALTER ROLE statement.
- F. A single role can be assigned to multiple users.
- G. A role is a named group of related privileges that can only be assigned to a user.
Answer: A,D,F
Explanation:
Roles in Oracle Database are designed to simplify the management of privileges. The following statements about roles are true:
* B: A single user can indeed be assigned multiple roles. This allows for easy management of user privileges as they can be grouped into roles, and these roles can be granted to users.
* D: A single role can be assigned to multiple users. This is one of the primary purposes of roles, to provide an efficient way to grant the same set of privileges to different users.
* G: Privileges are granted to a role using the GRANT statement. This allows the role to encapsulate the privileges which can then be granted to users.
The incorrect options are:
* A: Roles cannot be assigned to other roles using the ALTER ROLE statement; they are granted to other roles using the GRANT statement.
* C: Roles are not assigned to users using the ALTER USER statement; roles are granted to users using the GRANT statement.
* E: Privileges are not assigned to a role using the ALTER ROLE statement; they are granted using the GRANT statement.
* F: A role is not limited to being assigned to just one user; it can be assigned to multiple users.
