tag
The tag
command marks the current database state so you can roll back changes in the future.
Tip: If you want to apply a tag to your database within your changelog, write a changeset containing the tagDatabase
Change Type. To check whether a tag exists, use the tag-exists
command.
Uses
The tag
command is typically used to mark the current database state, version, release, or any other information by adding the tag to the last row in the DATABASECHANGELOG table. After setting the tag, you can use the rollback command to roll back all changes up to that tag.
The image below shows the DATABASECHANGELOG table structure. Running the command tag version1
applies the tag version1
to the last row in the DATABASECHANGELOG table. If you run rollback version1
command, it will roll back only createTable C
value.
Note: It is best practice to tag your changesets before running any other commands against your database.
Syntax
To run the tag
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 tag
command:
liquibase tag --tag=myTag
Note: The --tag=myTag
syntax was added in Liquibase 4.4. If you use an older version, specify your tag as a positional argument: <command> myTag
.
