SQL BETWEEN

Starting here? This lesson is part of a full-length tutorial in using SQL for Data Analysis. Check out the beginning.

In this lesson we'll cover:

• The SQL BETWEEN operator
• Practice problem

The SQL BETWEEN operator

BETWEEN is a logical operator in SQL that allows you to select only rows that are within a specific range. It has to be paired with the AND operator, which you'll learn about in a later lesson. Here's what BETWEEN looks like on a Billboard Music Chart Dataset:

SELECT *
  FROM tutorial.billboard_top_100_year_end
 WHERE year_rank BETWEEN 5 AND 10

BETWEEN includes the range bounds (in this case, 5 and 10) that you specify in the query, in addition to the values between them. So the above query will return the exact same results as the following query:

SELECT *
  FROM tutorial.billboard_top_100_year_end
 WHERE year_rank >= 5 AND year_rank <= 10

Some people prefer the latter example because it more explicitly shows what the query is doing (it's easy to forget whether or not BETWEEN includes the range bounds).
