Maven updateSQL

updateSQL is a helper goal that allows you to inspect the SQL Liquibase will run while using the Maven update goal.

Uses

updateSQL is typically used when you want to inspect the raw SQL before running the update goal, so you can correct any issues that may arise before running the goal. Liquibase uses the raw SQL to apply changes that you have added to the changelog file to the database.

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 updateSQL Maven goal

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

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

mvn liquibase:updateSQL

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 updateSQL Maven goal produces the following output:
