I started studying SQL from a very famous site - HackerRank. Here I will try to provide multiple approaches & solutions to the same problem. It will help you learn and understand SQL in a better way.

Please make use of my blog posts for learning purpose only and feel free to ask your questions in the comment box below in case of any doubt.

SQL Problem Statement:

Write a query that prints a list of employee names (i.e.: the name attribute) for employees in Employee having a salary greater than \$2000 per month who have been employees for less than 10 months. Sort your result by ascending employee_id.

Input Format:

The Employee table containing employee data for a company is described as follows:

where employee_id is an employee's ID number, name is their name, months is the total number of months they've been working for the company, and salary is their monthly salary.

Sample Input:

Sample Output:
Angela
Michael
Todd
Joe

Explanation:
Angela has been an employee for 1 month and earns \$3443 per month.
Michael has been an employee for 6 months and earns \$2017 per month.
Todd has been an employee for 5 months and earns \$3396 per month.
Joe has been an employee for 9 months and earns \$3573 per month.
We order our output by ascending employee_id.

### Solution: (MySQL Query):

SELECT NAME
FROM EMPLOYEE
WHERE SALARY > 2000
AND MONTHS < 10
ORDER BY EMPLOYEE_ID ASC;

NOTE:
1. The ORDER BY clause is used to get an ascending ordered list of Employees by their IDs.

### Sample Output:

Rose
Patrick
Lisa
Amy
Pamela
Jennifer
Julia
Kevin
Paul
Donna
Michelle
Christina
Brandon
