NEW QUESTION # 417
Examine the data in the PRODUCTS table:
Examine these queries:
1. SELECT prod name, prod list
FROM products
WHERE prod 1ist NOT IN(1020) AND category _id=1;
2. SELECT prod name, | prod _ list
FROM products
WHERE prod list < > ANY (1020) AND category _id= 1;
SELECT prod name, prod _ list
FROM products
WHERE prod_ list <> ALL (10 20) AND category _ id= 1;
Which queries generate the same output?
Answer: A
Explanation:
Based on the given PRODUCTS table and the SQL queries provided:
* Query 1: Excludes rows where prod_list is 10 or 20 and category_id is 1.
* Query 2: Includes rows where prod_list is neither 10 nor 20 and category_id is 1.
* Query 3: Excludes rows where prod_list is both 10 and 20 (which is not possible for a single value) and category_id is 1.
The correct answer is A, queries 1 and 3 will produce the same result. Both queries exclude rows where prod_list is 10 or 20 and include only rows from category_id 1. The NOT IN operator excludes the values within the list, and <> ALL operator ensures that prod_list is not equal to any of the values in the list, which effectively excludes the same set of rows.
Query 2, using the <> ANY operator, is incorrect because this operator will return true if prod_list is different from any of the values in the list, which is not the logic represented by the other two queries.
NEW QUESTION # 418
Which two statements are true? (Choose two.)
Answer: C,D

Incorrect options:
B: The SYSTEM user does not own all base tables of the data dictionary; some are owned by SYS.
C: Not all users have access to dynamic performance views prefixed with V$; access is restricted based on privileges.
D: The USER_OBJECTS view lists all objects owned by the user, not just tables and views but also other types of schema objects like procedures and functions.
