rollback-one-update
Note: This is a Liquibase Pro command, so you need a Liquibase Pro License Key to use it.
The rollback-one-update command reverts (rolls back) all changesets related by a specific deploymentId that was made during a previous change to your database. It is only available for Liquibase Pro users.
Uses
The rollback-one-update command is typically used when you want to undo a series of changes made to your database during a specific deployment and revert those changesets to their previous state without affecting any other changes made to your database.
The rollback-one-update command allows you to target a specific deploymentId without impacting other changes or deployments that came before or after it.
The image above shows deploymentIds 1 through 5, with deploymentId 2 incorporating all the changesets we want to roll back. As you can see, the rollback-one-update command allows you to target deploymentId 2 and revert all changesets associated with the same deploymentId to its previous state without impacting the others.
The impacts of rollback-one-update
Like any cherry-picking tool, using the rollback-one-update 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-update-sql command because it allows you to inspect the rollback-one-update SQL and search for any potential mistakes before you execute the rollback-one-update command.
The use of rollback-one-update comes with risk of unintended consequences, so you must also specify --force to indicate that you intend to run the command.
Additional impacts to the DATABASECHANGELOG table
Running the rollback-one-update command will remove the deployment record from the DATABASECHANGELOG table. As a user, you must decide on what to do with your changesets after the rollback-one-changeset command has been run.
Depending on your desired outcome, consider doing one of the following:
- Modify the changeset in the changelog file and re-deploy it.
- Do nothing to the changeset in the changelog file and have it be re-deployed.
- Delete the changeset in the changelog file.
Running the rollback-one-update command
Before running the rollback-one-update command, you can get the optional deploymentId of the deployment you want to revert by running the history command.
Note: If the deploymentId is not supplied, Liquibase Pro will look up the most recent deploymentId from the DATABASECHANGELOG table and use it for the rollback.
Then run the rollback-one-update command, with your information:
liquibase rollback-one-update --deploymentId=068379006 --forceFor more command specific help, type liquibase rollback-one-update --help into the command prompt.
