Consider the table employee (empId, name, department, salary) and the two queries Q1 and Q2 below.
Assuming that department 5 has more than one employee, and we want to find the employees who get higher salary in department 5, which one of the statements is TRUE for any arbitrary employee table?
Q1: Select e. empId
From employee
Where not exists
(Select * From employee s where s. department = "5" and s. salary > = e. salary)
Q2: Select e. empId
From employee e
Where e. salary > any
(select distinct salary From employee s where s. Where s. department = "5")

5 and s. salary > e. salary)
Q2: Select e. empId
From employee e
Where e. department = 5 and e. salary = (
Select max(salary) From employee where department = 5)
A. Q1 will always return the correct result
B. Q2 will always return the correct result
C. Both Q1 and Q2 will always return the correct result
D. Neither Q1 nor Q2 will always return the correct result
The correct answer is C. Both Q1 and Q2 will always return the correct result.
Explanation:
Q1 uses a subquery with the "not exists" condition to find employees in department 5 who do not have any other employee with a higher salary. This ensures that only the employees with the highest salary in department 5 are selected.
Q2 uses a subquery with the "max" function to find the maximum salary in department 5, and then selects the employees who have that maximum salary.
Both queries achieve the same result of finding the employees with the highest salary in department 5. Therefore, both Q1 and Q2 will always return the correct result for any arbitrary employee table.
Q2: Select e. empId
From employee e
Where e. department = 5 and e. salary = (
Select max(salary) From employee where department = 5)
A. Q1 will always return the correct result
B. Q2 will always return the correct result
C. Both Q1 and Q2 will always return the correct result
D. Neither Q1 nor Q2 will always return the correct result
The correct answer is C. Both Q1 and Q2 will always return the correct result.

Query Q2 is correct to calculate all the employee ids where salary is greater than any employee of department 5. So, it is correct.
But Q's sub-query is opposite and also incorrect as there is no comparison after the where clause.
