GREATEST in MySQL - Examples & AI Generator

MySQL’s GREATEST function helps you find the highest value among two or more columns or expressions—vital for reporting, ranking, and conditional business logic. Yet, GREATEST’s syntax can differ between database platforms, and memorizing MySQL’s quirks is often a pain for multi-database developers and analysts.

GREATEST Syntax in MySQL

The MySQL GREATEST function compares two or more expressions and returns the one with the highest value. It works with strings, numbers, and dates.

Syntax

GREATEST(expr1, expr2 [, exprN...])

  • At least two expressions are required.

  • If any argument is NULL, the result is NULL.

  • Slightly different from other SQL flavors (e.g., NOT supported in SQL Server), so MySQL syntax awareness is crucial.
