Liquibase conditional changeset

Liquibase

Liquibase allows you to run certain migrations depending on the dmbs you are executing the migration on. This can be done as follows:

  - changeSet:
      - id: 3-1
      - author: "Liam Clark"
      - preconditions:
            dbms: "h2"
      - changes:
            - createSequence:
                sequenceName: "HIBERNATE_SEQUENCE"

The names of the dmbs liquibase expects can be found here

apply liquibase changelog from cli:

liquibase --driver=org.h2.Driver \
            --classpath=$HOME/.m2/repository/com/h2database/h2/1.4.197/h2-1.4.197.jar \
            --changeLogFile=migrations.yaml \
            --url="jdbc:h2:./testdb" \
            --username=sa \
            --password="" \
            --logLevel=debug \
            update

More detailed instructions can be found in the TAM repository, in the CONTRIBUTION.MD file.
