rollback-count-sql
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.
Uses
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.
Syntax
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 Create and Configure a liquibase.properties File. You can also specify these properties in your command line.
Then run the rollback-count-sql
command:
liquibase rollback-count-sql --count=2 --changelog-file=example-changelog.xml
Note: The --count=myCount
syntax was added in Liquibase 4.4. If you use an older version, specify your count as a positional argument: <command> myCount
.
