Hi,
I am currently trying to understand the rollback feature of liquibase. I am unable to understand the execution of the rollback.
Here is my scenario.
I have an application A with the following DB schema
Id----firstname-----lastname------phonenumber
I update the application with email address so now my table looks like this
Id----firstname-----lastname------phonenumber------emailAddress
If the application is not successfully started then I wish to execute the rollback so that I remove the emailAddress.
How can I do it ? I fail to find any examples on the liquibase website so an example will be helpful
Regards
