Which among the following suffixes is not suitable for the root word ‘prevent’?

Option A. able
Option B. ing
Option C. ive
Option D. ious
True Answer D

Explanation :
When the suffix given in the options are added to the root word “prevent” we get the following new words: 1. Prevent + able = Preventable (Which means able to be prevented or avoided.) 2. Prevent + ing = Preventing (Which means keep (something) from happening.) 3. Prevent + ive = Preventive (Meaning designed to keep something undesirable such as illness or harm from occurring.) When the suffix – ious is added with ‘prevent’ it leads to formation of a new word which is meaningless. Hence suffix - ious is not suitable for the root word ‘prevent’

Given the following schema:

employees (emp-id, first-name, last-name, hire-date, dept-id, salary)
departments(dept-id, dept-name, manager-id, location-id)
You want to display the last names and hire dates of all latest hires in their respective departments in the location ID 1700. You issue the following query:
SQL>SELECT last-name, hire-date
FROM employees
WHERE (dept-id, hire-date) IN
(SELECT dept-id, MAX(hire-date)
FROM employees JOIN departments USING(dept-id)
WHERE location-id = 1700
GROUP BY dept-id);
What is the outcome?

Option A. It executes but does not give the correct result.
Option B. It executes and gives the correct result.
Option C. It generates an error because of pair wise comparison.
Option D. It generates an error because the GROUP BY clause cannot be used with table joins in a sub query.
True Answer B

Explanation :

 The given query uses below inner query,
SELECT dept-id, MAX (hire-date)
FROM employees JOIN departments USING (dept-id)
WHERE location-id = 1700
GROUP BY dept-id
The inner query produces last max hire-date in every department located at location id 1700. The outer query simply picks all pairs of inner query. Therefore, the query produces correct result.
SELECT last-name, hire-date
FROM employees
WHERE (dept-id, hire-date) IN
(Inner-Query);
Thus it executes and gives the correct result.
