unexpected-changesets

The unexpected-changesets command produces a list of changesets that were run in the database but do not exist in the current changelog.

Uses

The unexpected-changesets command is typically used to detect and compare the changes between the DATABASECHANGELOG table and the current changelog. If any of the changesets in the DATABASECHANGELOG table do not exist in the current changelog, the unexpected-changesets command will detect those changesets and produce them in your output.

The unexpected-changesets command also produces all the changesets that were previously deployed and deleted from your current changelog.

The following image shows the changelog file, which includes changesets for release 1 that are already applied to the database but removed from the changelog file and new changesets for release 2 that are not applied to the database. Running the unexpected-changesets command will produce the number of changesets applied for release 1.

So, if you want to identifying unexpected changesets that were previously applied to the database, run the unexpected-changesets command.

Syntax

To run the unexpected-changesets 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 unexpected-changesets command:

liquibase unexpected-changesets --changelog-file=example-changelog.xml

By default, the output shows the number of unexpected changesets. To see the list of unexpected changesets, add the --verbose flag:

liquibase unexpected-changesets --verbose --changelog-file=example-changelog.xml

Command 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.

Attribute Definition Requirement
--changelog-file

The root changelog

Required
--url

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

Required
--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
--password

Password to connect to the target database.

Optional
--username

Username to connect to the target database.

Optional
--verbose

Specifies the detail level of the command's output.

Optional

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.
