NEW QUESTION # 280
Examine the description of the EMPLOYEES table:

Which statement increases each employee's SALARY by the minimum SALARY for their DEPARTM ENT_ID?

A. UPDATE employees e1
SET salary=
(SELECT e1.salary + MIN(e2.salary)
FROM employees e2
WHERE e1. department_ id = e2.department_id);
B. UPDATE employees e1
SET salary =(SELECT e2. salary + MIN(e2.salary)
FROM employees e2
WHERE e1.department_ id = e2. department_id GROUP BY e2. department_id) ;
C. UPDATE employees e1
SET salary = salary+(SELECT MIN (salary)
FROM employees e2) ;
D. UPDATE employees e1
SET salary = salary +
(SELECT MIN(e1. salary)
FROM employees e2
WHERE e1.department_id = e2 .department_id);

Answer: A

Explanation:
The correct statement to increase each employee's salary by the minimum salary for their department is:
D: This option correctly increases each employee's salary by the minimum salary in their department. The subquery calculates the minimum salary for the department of the current row being updated (e1) in the outer UPDATE statement. The subquery does not use GROUP BY since it returns a single value - the minimum salary for the matching department.A, B, and C are incorrect. Specifically:
* A uses a subquery with an aggregate function combined with GROUP BY, which is not needed and will result in an error.
* B incorrectly references MIN(e1.salary) within the subquery, which is incorrect since e1 is the alias for the outer query's table and should not be used within the subquery.
* C sets the salary to itself plus the minimum salary across all employees, not filtered by the department.
References:
* Oracle Database SQL Language Reference, 12c Release 1 (12.1): "UPDATE"
