To find duplicate salaries within each department, you can modify the query as follows:

 SELECT Salary, Department, COUNT(*) AS DuplicateCount

FROM Employees

GROUP BY Salary, Department

HAVING COUNT(*) > 1;

Explanation:

• GROUP BY Salary, Department ensures that duplicates are checked within each department.
• COUNT(*) counts occurrences of each (Salary, Department) combination.
• HAVING COUNT(*) > 1 filters out unique salaries, showing only duplicates.

Example:

Given Employees Table:

EmployeeID	Name	Salary	Department
1	John	5000	IT
2	Alice	6000	HR
3	Mark	5000	IT
4	David	7000	Sales
5	Steve	6000	HR
6	Bob	5000	HR

Query Output:

Salary	Department	DuplicateCount
5000	IT	2
6000	HR	2

This means that:

• Salary 5000 appears twice in the IT department.
• Salary 6000 appears twice in the HR department.
