DENSE RANK in MySQL - Examples & AI Generator

Understanding DENSE RANK in MySQL is essential for data analysts, developers, and database engineers working with complex ranking queries. Unlike simpler ranking functions, DENSE RANK assigns consecutive ranks without gaps, which is especially useful for grouped business reports. The challenge: MySQL’s ranking syntax can be verbose, and remembering DENSE_RANK() usage—not to mention adapting it for different business scenarios—can slow you down.

With AI2sql, you skip manual SQL construction entirely. Instantly turn natural-language descriptions into production-ready DENSE RANK queries for MySQL—no coding required.

DENSE RANK Syntax in MySQL

MySQL DENSE RANK Function

MySQL supports the DENSE_RANK() window function from version 8.0 onward. Typical syntax:

DENSE_RANK() OVER (PARTITION BY column1 ORDER BY column2 [ASC|DESC])

• PARTITION BY: Resets the rank for each group (e.g., per department).

• ORDER BY: Specifies sorting within each partition.

Note: MySQL’s DENSE RANK differs slightly from other databases—syntax and order clause placement matter.
