PostgreSQL Operators

Use operators to compare values, combine conditions, calculate values, and match patterns.

Comparison operators

Comparison operators return true or false. Common operators include =, <>, >, <, >=, and <=.

SELECT * FROM products
WHERE year >= 2025;

Logical and arithmetic operators

SELECT * FROM products
WHERE year >= 2024 AND name <> 'Laptop';

SELECT year + 1 AS next_year
FROM products;

Use AND, OR, and NOT to combine conditions. Parentheses make complex conditions clear.
