Prerequisites

Install drivers

To use Liquibase and MaxDB, you need:

Place your JAR file(s) in the liquibase/lib directory. Read more: Adding and Updating Liquibase Drivers.

If you use Maven, note that this database does not provide its driver JAR on a public Maven repository, so you must install a local copy and add it as a dependency to your pom.xml file. Read more: Configuring Liquibase Attributes in your Maven POM File.

<dependency>
    <groupId>com.sap</groupId>
    <artifactId>sapdbc</artifactId>
    <version>7.4.4</version>
</dependency>
<dependency>
    <groupId>org.liquibase.ext</groupId>
    <artifactId>liquibase-maxdb</artifactId>
    <version>4.17.2</version>
</dependency>

Test your connection

  1. Ensure your MaxDB database is configured. See MaxDB Installation on Microsoft Windows and Linux for more information.
  2. Specify the database URL in the Liquibase properties file. Liquibase does not parse the URL. You can either specify the full database connection string or specify the URL using your database's standard JDBC format:
  3. url: jdbc:sapdb://localhost:7200/MaxDB1

    Tip: To apply a Liquibase Pro key to your project, add the following property to the Liquibase properties file: liquibaseProLicenseKey: <paste code here>

  1. Create a text file called changelog (.xml, .sql, .json, or .yaml) in your project directory and add a changeset.
  2. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful:
  3. liquibase --username=test --password=test --changelog-file=<changelog.xml> status

    Note: You can pass arguments in the CLI or keep them in the Liquibase properties file.

  4. Inspect the SQL with the update-sql command. Then make changes to your database with the update command.
  5. liquibase --changelog-file=<changelog.xml> update-sql
    liquibase --changelog-file=<changelog.xml> update
  6. From a database UI tool, ensure that your database contains the test_table you added along with the DATABASECHANGELOG table and DATABASECHANGELOGLOCK table.
