BETWEEN

🎬 Scenario: Finding Mid-Range Netflix Releases

Your manager at Netflix, Alex, is analyzing mid-era releases and wants to focus on shows released between 2015 and 2020.

Alex asks:

Can you retrieve all Netflix series that were released between 2015 and 2020?

Your task is to query the netflix_series table and provide the requested data.

1. Filtering Data with BETWEEN

The BETWEEN operator filters results within a specified range, including both the lower and upper values.

Syntax

1SELECT column1, column2  
2FROM table_name  
3WHERE column_name BETWEEN value1 AND value2;

• BETWEEN value1 AND value2 includes both value1 and value2 in the result.
• It’s equivalent to: WHERE column_name >= value1 AND column_name <= value2;

2. Using BETWEEN for Release Year Filtering

Instead of writing:

1SELECT title, release_year  
2FROM netflix_series  
3WHERE release_year >= 2015 AND release_year <= 2020;

You can write:

1SELECT title, release_year  
2FROM netflix_series  
3WHERE release_year BETWEEN 2015 AND 2020;

What’s Happening?

• BETWEEN 2015 AND 2020 filters results to only include release years from 2015 to 2020.
• The same query using >= and <= would be longer and harder to read.

3. Using BETWEEN for Ratings

You can also apply BETWEEN to numeric values like ratings.

Example Query: Finding Shows with Ratings Between 8.0 and 9.0

1SELECT title, rating  
2FROM netflix_series  
3WHERE rating BETWEEN 8.0 AND 9.0;

What’s Happening?

• BETWEEN 8.0 AND 9.0 filters results to only include shows with ratings between 8.0 and 9.0.
• The query still includes 8.0 and 9.0.

✍️ SQL Exercises

Exercise 1: Finding Shows Released Between 2015 and 2020

Alex wants a report showing all series released between 2015 and 2020, sorted by release_year in ascending order, then title in ascending order.

Filter condition:

• release_year must be between 2015 and 2020.
• Sort by release_year in ascending order, then title in ascending order.

Write an SQL query to return the requested data.

Exercise 2: Finding Shows with Ratings Between 8.0 and 9.0

Alex wants to focus on highly-rated Netflix shows that have ratings between 8.0 and 9.0.

Filter condition:

• rating must be between 8.0 and 9.0.
• Sort by rating in ascending order, then title in ascending order.

Write an SQL query to return the requested data.
