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.

Running the unexpected-changesets command

To run the unexpected-changesets command, specify the driver, classpath, and URL in the Liquibase properties file. For more information, see Specifying Properties in a Connection Profile. You can also specify these properties in your command line.

Then run the unexpected-changesets command:

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

Note: Enter the name of the changelog you want to use in place of changelog.xml. You can also specify the changelog file in the properties file. The output shows the number of unexpected changesets.

To see the list of unexpected changesets, add the --verbose flag while running the command:

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