rollback-one-changeset

Note: This is a Liquibase Pro command, so you need a Liquibase Pro License Key to use it.


The rollback-one-changeset command reverts (rolls back) one non-sequential changeset made during a previous change to your database. It is only available for Liquibase Pro users.

Uses

The rollback-one-changeset command is typically used when you want to undo a change made to your database and revert it to a previous state without affecting any other changes made to your database.

While the rollback command reverts all changesets deployed sequentially to a specified point by using rollbackDate, rollback-count, or rollback <tag_name>, the rollback-one-changeset command allows you to target a specific changeset without impacting changesets that came before or after it.

The image above shows changesets A through I, with changeset I being the most recently deployed. As you can see, the rollback-one-changeset command allows you to target changeset B and revert it to its previous state without impacting the others.

Impact

Like any targeted tool, using the rollback-one-changeset command comes with risks of unintended consequences. Because of this, the command requires a --force flag to indicate that you intend to run it.

Warning: Look for potential unintended consequences before using this command.

It is a best practice to run the rollback-one-changeset-sql command because it allows you to inspect the rollback SQL and search for any potential mistakes before you execute rollback-one-changeset.

Syntax

Before running the rollback-one-changeset command, gather the following information from your DATABASECHANGELOG table or by running the history command:

  • The author of the changeset you want to revert
  • The ID of the changeset you want to revert
  • The file path and name of the changeset you want to revert

Then run the rollback-one-changeset command, with your information:

liquibase rollback-one-changeset --changelog-file=example-changelog.xml --changeset-author="LiquibaseProUser" --changeset-id="createProc-proschema" --changeset-path=changelog.xml --force

For more command-specific help, type liquibase rollback-one-changeset --help into the command prompt.

Global arguments

Tip: For best results, specify all commands and parameters in the --kebab-case format in the CLI. If your preference is camelCase, it also works in the CLI.

Attribute Definition Requirement
--license-key

Your Liquibase Pro license key

Command arguments

Attribute Definition Requirement
--changeset-author

The name of the author for the changeset. Supports * as a wildcard.

Required
--changeset-id

The changeset ID from the changelog.

Required
--changelog-file

The root changelog

Required
--changeset-path

The path to the changelog containing the changeset you want to roll back.

Required
--force

A required parameter which indicates you intend to use this feature.

Required
--url

The JDBC database connection URL. See Using JDBC URL in Liquibase.

Required
--change-exec-listener-class

Optional
--default-catalog-name

Name of the default catalog to use for the database connection

Optional
--default-schema-name

Name of the default schema to use for the database connection. If defaultSchemaName is set, then objects do not have to be fully qualified. This means you can refer to just mytable instead of myschema.mytable.

Tip: In Liquibase v4.23.0+, camelCase for defaultSchemaName works successfully. If you are on an earlier version, camelCase may not work as expected.

Note: The syntax liquibase.command.defaultSchemaName is valid for v4.19.0+. For prior versions, use defaultSchemaName.

Optional
--driver

The JDBC driver class

Optional
--driver-properties-file

The JDBC driver properties file

Optional
--password

Password to connect to the target database.

Tip: It is a best practice to store sensitive data in a Secrets Management tool with Liquibase Pro.

Optional
--rollback-script

The path to the script to use to perform the rollback. Only needed if the rollback is not already defined in the changelog, and if it is not a rollback statement that is automatically generated by Liquibase.

Optional *
--username

Username to connect to the target database.

Tip: It is a best practice to store sensitive data in a Secrets Management tool with Liquibase Pro.

Optional

Note: The username and password attributes are not required for connections and systems which use alternate means of authentication. Also, you can specify database credentials as part of the url attribute.
