SQL BETWEEN Operator

What is the BETWEEN Operator?

BETWEEN filters rows where a column value falls within an inclusive range. It is shorthand for >= low AND <= high.

Syntax

SELECT * FROM table_name
WHERE column BETWEEN low AND high;

When to Use

  • Filtering dates within a range
  • Selecting products in a price range
  • Finding ages between two values

Key Points

  1. InclusiveBETWEEN 10 AND 20 includes both 10 and 20.
  2. NOT BETWEEN — Excludes the range: WHERE age NOT BETWEEN 18 AND 25.
  3. Date Ranges — Works well with dates: WHERE created_at BETWEEN '2024-01-01' AND '2024-12-31'.
  4. Order Matters — The lower bound must come first. BETWEEN 20 AND 10 returns no rows.
  5. Timestamps — Be careful with timestamps: BETWEEN '2024-01-01' AND '2024-01-31' may miss records on Jan 31 after midnight. Use < '2024-02-01' for precision.

Frequently Asked Questions

Is BETWEEN inclusive or exclusive?
BETWEEN is inclusive on both ends. WHERE age BETWEEN 18 AND 25 includes ages 18 and 25.
Can I use BETWEEN with strings?
