# Function Differences Between MariaDB 10.3 and MySQL 5.7

The following is a list of all function differences between [MariaDB 10.3](/docs/release-notes/community-server/old-releases/10.3/what-is-mariadb-103.md) and MySQL 5.7. It is based on functions available in the stable versions MySQL 5.7.18 and [MariaDB 10.3.29](/docs/release-notes/community-server/old-releases/10.3/10.3.29.md).

For a description of all differences, see [Incompatibilities and Feature Differences Between MariaDB 10.3 and MySQL 5.7](/docs/release-notes/community-server/about/compatibility-and-differences/incompatibilities-and-feature-differences-between-mariadb-and-mysql-unmaint/compatibility-differences-incompatibilities-and-feature-differences-between.md).
