rollbackOneChangeSet command


The rollbackOneChangeSet 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 rollbackOneChangeSet 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, rollbackCount, or rollback <tag_name>, the rollbackOneChangeSet 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 rollbackOneChangeSet command allows you to target changeset B and revert it to its previous state without impacting the others.

The impacts of rollbackOneChangeSet

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

Please look for potential unintended consequences before using this command.

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

Also, the use of rollbackOneChangeSet 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 rollbackOneChangeSet command

Before running the rollbackOneChangeSet 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 rollbackOneChangeSet command, with your information:

liquibase --changeLogFile=changelog.xml rollbackOneChangeSet --changeSetAuthor="Liquibase Pro User" --changeSetId="1::createProc-proschema" --changeSetPath=changelog.xml --force

For more command specific help, type liquibase rollbackonechangeset --help into the command prompt.
