Liquibase
provides an update
command, which executes all the ChangeSets
in a ChangeLog
file. To verify the executed ChangeSets
, Liquibase
provides a history
command that lets the DBA
inspect the history
of all the ChangeSets
to ensure they have been executed successfully.
The history
command will list all the deployed ChangeSets
along with its deploymentId
