`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

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
`--password=<string>`	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
`--username=<string>`	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
`--verbose=<true\|false>`	Specifies the detail level of the command's output.	Optional
