The rollbackCountSQL command is a helper command that allows you to inspect the SQL Liquibase will run while using the rollbackCount command.


The rollbackCountSQL command is used when you want to inspect the raw SQL before running the rollbackCount 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 rollbackCountSQL command

Before running the rollbackCountSQL command, you can run the history command to see all your previously executed changes.

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

To run the rollbackCountSQL command, you can specify the driver, classpath, and URL in your file. For more information, see Creating and configuring a file. You can also specify these properties in your command line.

Then run the rollbackCountSQL command:

liquibase --changeLogFile=mychangelog.postgresql.sql rollbackCountSQL 1

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