What is a Change type?
Last updated: August 12, 2026
A Change Type is a database-independent XML, YAML, or JSON formatted change that you can specify to update your database with Liquibase. Change Types correspond to SQL statements applied to your database, such as CREATE TABLE. You specify the Change Type you want to use within a Changeset in your Changelog. It is a best practice to include only one Change Type per changeset. Doing so avoids failed auto-commit statements that can leave the database in an unexpected state.
You can browse in this category in the sidebar navigation to see all change types that you can apply to your database with the default Liquibase installation. You can also write your own changes through the extension system.
Notes
Property values are strings unless otherwise noted.
Boolean parameters are defaulted to false unless otherwise noted.
Some change types automatically create rollback statements when you run rollback commands.
