Code:
-- Selecting the first_name, last_name, and salary columns
SELECT first_name, last_name, salary,
-- Calculating 15% of the salary and aliasing it as "PF" (Provident Fund)
salary * 0.15 AS PF
-- Selecting data from the employees table
FROM employees;
Explanation:
- This SQL query selects specific columns (first_name, last_name, salary) from the employees table.
- It also calculates a new column by multiplying the salary by 0.15 (which represents 15% of the salary).
- The result of this calculation is aliased as "PF", representing the Provident Fund.
- This query is useful for generating a report that includes employee names, their salaries, and the corresponding Provident Fund contribution based on a 15% deduction from their salaries.
