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.

The impacts of rollback-one-changeset

Like any cherry-picking tool, using the rollback-one-changeset command comes with risks which may be unintended.

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.

Also, the use of rollback-one-changeset comes with risk of unintended consequences, because of this, the command requires a --force flag to indicate that you intend to run the command.

Running the rollback-one-changeset command

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

  • The Author of the changeset you want to revert
  • The changeset ID of the changeset you want to revert
  • The file name (changeset path) of the changeset you want to revert

Note: The --rollbackScript is only needed if the rollback is not already defined in the changelog, and if it is not a rollback that is automatically provided by Liquibase.

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

liquibase --changelog-file=changelog.xml rollback-one-changeset --changeSetAuthor="LiquibaseProUser" --changeSetId="createProc-proschema" --changeSetPath=changelog.xml --force

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