SQL Challenge #DAY2: Calculate the Year-over-Year Sales Growth

Hey everyone!

Today, we're diving into a new SQL challenge. Given the dataset below, your task is to calculate the year-over-year (YoY) sales growth percentage for each employee. Use a window function to compare the sales of the current year with the previous year.

Sample Data:

Sale_ID Sale_Date Employee_ID Amount ($)
1 2023-09-01 101 1500
2 2023-09-01 102 1700
3 2024-09-01 101 1600
4 2024-09-02 103 1800
5 2024-09-02 101 1400
6 2024-09-02 102 1900
7 2023-09-03 103 1500
8 2023-09-03 101 1600
9 2024-09-03 102 2000
10 2024-09-14 103 2100

Your task:
Write a SQL query to calculate the year-over-year sales growth for each employee using window functions. How much did their sales grow or decline compared to the same period in the previous year?

The market is slow, jobs are drying up and unfortunately a lot of students graduating this year won't find a job ( At Least not right away)
. With a passion for empowering young people to achieve their dreams I plan to do my part by assisting 3 students find their 1st job.
I am offering a free 100 days data analyst program to 3 chosen students whom I will personally teach on a weekday basis.

2. Querying Relational Database using SQL
3. Business Analysis Projects of 3 Different Domains.
4. Data Extraction and Transformation using an ETL tool
5. Data Visualization using PowerBI
6. Version Management using GIT


The course will be challenging, but highly rewarding, consisting of 100 practice exercises, all of which will have to be completed on the same day of assignment.
Also six marathon coding sessions of eight hours each will be conducted in the program.

Dedication and commitment are essential for success in this program, and students will be expected to devote eight hours each day for the next 100 days to completing the course.
If you know a recent or soon-to-be graduate who is hard-working, committed, and eager to take on this challenge,
please encourage them to apply. This opportunity is a rare chance to gain valuable hands-on experience, learn from industry experts,
and propel their career in data analytics to new heights. Don't let them miss out!
