Maven changelogSyncSQL

changelogSyncSQL is a helper goal that produces the raw SQL Liquibase would run when using the changelogSync goal.

Uses

changelogSyncSQL is typically used when you want to inspect the SQL Liquibase will use to baseline a new database environment and update the DATABASECHANGELOG table to mark all changes that are not applied to the database as executed.

It is best practice to inspect any SQL that Liquibase would run when using the changelogSync goal so you can review any changes the goal would make to your database before running the goal.

Maven configuration

You can configure Liquibase Maven in multiple ways. You can pass arguments like <changeLogFile> in Maven directly in your pom.xml file, in a liquibase.properties file referenced in your POM, as environment variables, or as JVM system properties.

Tip: For more information about the Maven configuration, see Configuring Maven.

Running the changelogSyncSQL Maven goal

Running the changelogSyncSQL goal requires a Maven project to be implemented.

To run the goal, type the following in your command prompt:

mvn liquibase:changelogSyncSQL

Note: You can also add the liquibase.migrationSqlOutputFile attribute and specify the file to output the migration SQL script to. The default file is migrate.sql. If it exists, it will be overwritten.

When successful, the changelogSyncSQL Maven goal produces the following output:
