Maven rollbackOneChangeSet

rollbackOneChangeSet rolls back one non-sequential changeset that is deployed to your database. It is only available for Liquibase Pro users.

Uses

rollbackOneChangeSet 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 goal reverts all the deployed changesets sequentially to a specified point, the rollbackOneChangeSet goal allows you to target a specific changeset without impacting changesets that came before or after it.

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

The impacts of rollbackOneChangeSet

Using the rollbackOneChangeSet goal comes with risks of unintended consequences. For this reason, it is a best practice to run the rollbackOneChangeSetSQL goal because it allows you to inspect the rollback SQL and search for any potential mistakes before you execute rollbackOneChangeset.

Also, as the use of rollbackOneChangeSet comes with risks of unintended consequences, the goal requires a liquibase.force attribute to specify that you intend to run the goal.

Maven configuration

Liquibase Maven can be configured in multiple ways. One way is to define your Liquibase configuration properties in your pom.xml file. To configure your pom.xml file, refer to Configuring Liquibase Attributes in your Maven POM File. If your pom.xml does not reference a liquibase.properties file, include <changeLogFile>specify your changelog file here</changeLogFile> and <ProLicenseKey>specify your Liquibase Pro license key here</ProLicenseKey> to the pom.xml file.

Running the rollbackOneChangeSet Maven goal

Before running the rollbackOneChangeSet goal, gather the following information from your DATABASECHANGELOG table:

• The author of the changeset you want to revert
• The id of the changeset you want to revert
• The filename (changeset path) of the changeset you want to revert

Note: The liquibase.rollbackScript script is only needed if the rollback is not yet defined in the changelog and if it is not a rollback that is automatically provided by Liquibase.

Also, you can run the history goal to see the history of all deployments against the configured database:

mvn liquibase:history

Next, run the rollbackOneChangeSet goal, with your information:

Note: Running the rollbackOneChangeSet goal requires a Maven project to be implemented.

mvn liquibase:rollbackOneChangeSet
-Dliquibase.changeSetAuthor="LiquibaseProUser"
-Dliquibase.changeSetId="createProSchema"
-Dliquibase.changeSetPath="changelog.xml" -Dliquibase.force

Note: Enter the name of the changeset author, id, and the path with the changelog filename that you want to use in place of LiquibaseProUser, createProSchema, and changelog.xml. For more information, run mvn liquibase:help -Ddetail=true -Dgoal=rollbackOneChangeSet.

liquibase.emptyPassword [boolean]	Deprecated. Use an empty or null value for the password instead. Default value is: false.
expressionVariables	Specifies a map-based collection of changelog properties to apply.
expressionVars	Specifies a property-based collection of changelog properties to apply.
liquibase.includeArtifact [boolean]	Includes a Maven project artifact in the class loader which obtains the liquibase.properties file and changelog files. Default value is: true.
liquibase.includeTestOutputDirectory [boolean]	Includes the Maven test output directory in the class loader which obtains the liquibase.properties file and changelog files. Default value is: true.
liquibase.labels	Specifies which labels Liquibase will execute, which can be separated by a comma if multiple labels are required or you need to designate a more complex expression. If a label is not specified, then all labels will be executed.
liquibase.outputDefaultCatalog [boolean]	Specifies whether to ignore the catalog or database name. Default value is: false.
liquibase.outputDefaultSchema [boolean]	Specifies whether to ignore the schema name. Default value is: false.
liquibase.outputFileEncoding	Indicates that you want to set the character encoding of the output file during the updateSQL phase.

liquibase.propertyFile	Specifies the liquibase.properties file you want to use to configure Liquibase.
liquibase.propertyFileWillOverride [boolean]	Indicates that you want the liquibase.properties file to override any settings provided in the Maven plugin configuration. By default, if a property is explicitly specified, it is not overridden if it also appears in the properties file. Default value is: false.
