future-rollback-count-sql

The future-rollback-count-sql command generates the SQL that Liquibase would use to sequentially revert the number of changes associated with undeployed changesets, which are added to a changelog file.

Uses

The future-rollback-count-sql command is typically used to inspect the SQL before rolling back the number of changesets that you have not deployed to your database but added to your changelog. The command shows the output starting with the most recent changes until the value specified is reached.

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

Syntax

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

liquibase future-rollback-count-sql --count=2 --changelog-file=example-changelog.xml

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

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

--count=<int>

Integer specifying how many changes Liquibase applies the command to. Specify as --count=myCount. Positional format <command> <count> deprecated in 4.4+.

 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.

 Optional

--username=<string>

Username to connect to the target database.
