# Function Differences Between MariaDB 11.4 and MySQL 8.0

The following is a list of all function differences between [MariaDB 11.4](https://mariadb.com/docs/release-notes/community-server/11.4/what-is-mariadb-114) and MySQL 8.0. It is based on functions available in the MySQL 8.0.36 and the [MariaDB 11.4.1](https://mariadb.com/docs/release-notes/community-server/11.4/11.4.1) releases. For a more complete list of differences, see [Incompatibilities and Feature Differences Between MariaDB 11.4 and MySQL 8.0](https://mariadb.com/docs/release-notes/community-server/about/compatibility-and-differences/incompatibilities-and-feature-differences-between-mariadb-11-4-and-mysql-8)
