ORDER BY Syntax in PostgreSQL

PostgreSQL uses a straightforward ORDER BY clause, but it differs slightly in handling NULLs and expressions compared to other databases. The basic syntax:

SELECT column1, column2
FROM table_name
ORDER BY column1 [ASC|DESC] [NULLS FIRST|NULLS LAST];

• ASC (default): sorts in ascending order.

• DESC: sorts in descending order.

• NULLS FIRST/LAST: control where NULL values appear (PostgreSQL only).
