The rollback-count-sql command is a helper command that allows you to inspect the SQL Liquibase will run while using the rollback-count command.


The rollback-count-sql command is used when you want to inspect the raw SQL before running the rollback-count command, so you can correct any issues that may arise before running the command. Liquibase uses the raw SQL to revert any changesets between the most recent and the value you specified.

Running the rollback-count-sql command

Before running the rollback-count-sql command, you can run the history command to see all your previously executed changes.

Note: rollback-countSQL works from the bottom of the list towards the top. Also, unlike the rollback-count command, there is no impact of this command. See the rollback-count topic for more information.

To run the rollback-count-sql 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 rollback-count-sql command:

liquibase --changelog-file=mychangelog.postgresql.sql rollback-count-sql 1

Note: Enter the name of the changelog and value you want to use in place of mychangelog.postgresql.sql and 1.

rollback-count-sql global attributes

Tip: All commands and parameters use the --kebab-case format in the CLI environment. This is the format Liquibase recommends for best results. If your preference is camelCase, it will still work in the CLI.

Attribute Definition Requirement
--changelog-file * Specifies the root changelog Required
--url Specifies the JDBC database connection URL Required
--username Specifies the database username Required
--password Specifies the database password Required
