update-to-tag

The update-to-tag command applies sequential changes to your database from the newest changeset to the changeset with the tag you specified and applied earlier.

Uses

The update-to-tag command is mainly used to apply changes sequentially, starting with the changesets from the top of the changelog file until the specified tag is reached. Even though there are other undeployed changes in the changelog, the command deploys only the changesets associated with a specific tag.

The update-to-tag command will deploy changes only when you have tagDatabase Change Type in your changelog file. You cannot use the update-to-tag command with the reference to a tag created in the DATABASECHANGELOG table using the tag command.

The following image shows that if you run the update-to-tag command with the tag version1, which should be specified in the changelog file as a tagDatabase changeset, Liquibase will deploy createTable A, createTable B, and version1 without deploying createTable C.

Note: Currently, the tagDatabase Change Type is not supported in the formatted SQL changelog. The supported formats are XML, YAML, and JSON. If you have a root XML changelog that includes formatted SQL files, you can apply a changeset with a tag between the formatted SQL files. For more information, see Best Practices.

Additionally, it is best practice to run the update-to-tag-sql helper command to inspect the update-to-tag SQL, so you can correct any issues that may arise before running the command.

Running the update-to-tag command

To run the update-to-tag command, specify the driver, classpath, and URL in the Liquibase properties file. You can also specify these properties in your command line.

Then run the update-to-tag command:

liquibase --changelog-file=communityOnly.xml update-to-tag version1

Note: Enter the name of the changelog and the tag that you want to use in place of communityOnly.xml and version1.

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.
