I have configured the maven pluggin for liquibase as specified in maven configuration.
Now created a changeset like :-
Created the sql to update DB using command line :- mvn liquibase:updateSQL
But just want to know how to rollback using a "rollbackTag" parameter. i.e. If run the command "mvn liquibase:rollbackSQL", what should be the value of "rollbackTag" parameter.
And is it possible to rollback using the changeset id ?
Rollback tags are designed to checkpoint your database's configuration.
The following commands will roll the database configuration back by 3 changesets and create a tag called "checkpoint":
mvn liquibase:rollback -Dliquibase.rollbackCount=3 mvn liquibase:tag -Dliquibase.tag=checkpoint You can now update the database, and at any stage rollback to that point using the rollback tag:
mvn liquibase:rollback -Dliquibase.rollbackTag=checkpoint or alternatively generate the rollback SQL:
mvn liquibase:rollbackSQL -Dliquibase.rollbackTag=checkpoint I initially found it difficult to figure out how to configure the liquibase Maven plugin. Just in case it helps here's the example I've used.
The liquibase update is configured to run automatically, followed by tagging the database at the current Maven revision number.
4.0.0 com.myspotontheweb.db liquibase-demo 1.0-SNAPSHOT jdbc:h2:target/db1/liquibaseTest;AUTO_SERVER=TRUE org.h2.Driver user pass com/myspotontheweb/db/changelog/db-changelog-master.xml false com.h2database h2 1.3.162 dbupdate true org.liquibase liquibase-maven-plugin 2.0.2 process-resources ${project.version} update tag Liquibase is now configured as part of the standard life-cycle so can be run as follows:
mvn clean compile I personally prefer to put the tag as part of the changeset files, so if you have to rollback or delete all the records in the DATABASECHANGELOG you won't loose your tagging records.
