Oracle Demo: Sync Database Schema Changes with Liquibase
$ sqlcl -nolog @run-liquibase.sql
lb generate-schema
lb generate-schema captures the schema to which SQLcl is connected into a controller.xml file in the current working directory.
This controller file is acts as a change log that includes all files in the proper order to allow the schema to be deployed correctly.
cd liquibase/out
lb generate-schema
cd ../..
Compare generate-schema with generate-changelog.
