Code:
-- Selecting the first_name, last_name, and calculating the monthly salary
SELECT first_name, last_name,
-- Dividing the salary by 12 to calculate the monthly salary and rounding it to 2 decimal places
ROUND(salary / 12, 2) AS 'Monthly Salary'
-- Selecting data from the employees table
FROM employees;
Explanation:
- This SQL query selects the first_name and last_name columns from the employees table.
- It also calculates the monthly salary by dividing the salary column by 12, assuming the salary is given on an annual basis.
- The ROUND() function is used to round the result of the division to 2 decimal places.
- The result is displayed in the result set with the alias 'Monthly Salary'.
- This query is useful when you want to convert annual salaries into monthly figures for easier comparison or reporting purposes.
