rollback-to-date-sql

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

Uses

The rollback-to-date-sql command is typically used when you want to inspect the raw SQL before running the rollback-to-date command, so you can correct any issues that may arise before running the command.

Running the rollback-to-date-sql command

Before running the rollback-to-date-sql command, you can see the dates of all previous changes by running the history command.

Note: Unlike the rollback-to-date command, there is no impact to your database while using this command.

To run the rollback-to-date-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-to-date-sql command:

liquibase --changelog-file=postgres_lbpro_master_changelog.xml rollback-to-date-sql 2020-05-07

Note: Enter the name of the changelog and date you want to use in place of postgres_lbpro_master_changelog.xml and 2020-05-07.
