rollback-sql

The rollback-sql tag is a helper command that produces the raw SQL Liquibase would run when using the rollback command.

Uses

The rollback-sql command is typically used to inspect the SQL Liquibase uses to revert changes associated with a tag you specify when you run the rollback command. It is best practice to use the rollback-sql command before running the rollback command to ensure that you eliminate any potential risks.

Syntax

To run the rollback-sql command, specify the driver, classpath, and URL in the Liquibase properties file. For more information, see Create and Configure a liquibase.properties File. You can also specify these properties in your command line.

Then run the rollback-sql command:

liquibase rollback-sql --tag=myTag --changelog-file=example-changelog.xml

Note: The --tag=myTag syntax was added in Liquibase 4.4. If you use an older version, specify your tag as a positional argument: <command> myTag.

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.

Attributes Definition Requirement
--output-file

File path to where the command output will be written. If not specified, output goes to STDOUT. See --output-file.

 Optional

Command arguments

Attribute Definition Requirement
--changelog-file*

The root changelog

 Required
--url

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

 Required
--tag

The tag identifying which tagged changesets in the changelog to evaluate. Specify as --tag=myTag. Positional format <command> <tag> deprecated in 4.4+.

 Required
--change-exec-listener-class

Fully-qualified class which specifies a ChangeExecListener. For more information, see Implementing a Custom ChangeExecListener Class with Liquibase and ChangeExecListenerCommandStep.

 Optional
--change-exec-listener-properties-file

Path to a properties file for the ChangeExecListener class. For more information, see Implementing a Custom ChangeExecListener Class with Liquibase and ChangeExecListenerCommandStep.

 Optional
--context-filter

Specifies the changeset contexts to match. Contexts are tags you can add to changesets to control which changesets are executed in any particular migration run.

Note: If you use Liquibase 4.23.0 or earlier, use the syntax --contexts instead of --context-filter.

 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
--label-filter

Specifies the changeset labels to match. Labels are tags you can add to changesets to control which changesets will be executed in any migration run.

 Optional
--output-default-catalog

Control whether names of objects in the default catalog are fully qualified or not. If true, they are. If false, only objects outside the default catalog are fully qualified Default: true.

 Optional
--output-default-schema

Control whether names of objects in the default schema are fully qualified or not. If true, they are. If false, only objects outside the default schema are fully qualified Default: true.

 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
--tag-version

Tag version to use for multiple occurrences of a tag. Valid values are NEWEST and OLDEST. If set to NEWEST, Liquibase rolls back changes up to the most recent instance of the tag. Any older instances of the tag remain in the DATABASECHANGELOG table. If set to OLDEST, Liquibase rolls back changes up to the first instance of the tag. Default: OLDEST

 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

* Liquibase checks nested changelogs for definitions of the changesets to rollback.

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.
