future-rollback-sql

The future-rollback-sql command is a helper command that produces the raw SQL Liquibase would need to roll back changes that have not yet been deployed to your database.

Uses

You can use the future-rollback-sql command to inspect the raw SQL Liquibase would use to revert changes associated with undeployed changesets.

It is best practice to inspect SQL Liquibase would run when using the update command so you can review any changes the command would make to your database.

Note: The update-sql command is a helper command that you can also use before running the update command. The main difference is that update-sql creates objects associated with undeployed changesets, and future-rollback-sql drops objects associated with undeployed changesets.

Syntax

To run the future-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 future-rollback-sql command:

liquibase --output-file=example-file.txt future-rollback-sql --changelog-file=example-changelog.xml

Parameters

Global parameters

Attribute Definition Requirement

--output-file=<string>

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

Optional

Command parameters

Attribute Definition Requirement

--changelog-file=<string>

The root changelog

Required

--url=<string>

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

Required

--context-filter=<string>

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=<string>

Name of the default catalog to use for the database connection

Optional

--default-schema-name=<string>

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=<string>

The JDBC driver class

Optional

--driver-properties-file=<string>

The JDBC driver properties file

Optional

--label-filter=<string>

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=<true|false>

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=<true|false>

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=<string>

Password to connect to the target database.
