How to specify an Empty Rollback using SQL Dialect

Environment

Liquibase Version: 4.13 Liquibase Integration & Version: GitHub Action Liquibase Extension(s) & Version: 7 Database Vendor & Version: Snowflake Operating System Type & Version: Linux Infrastructure Type/Provider: Azure

Description

Unable to specify an empty rollback for a changeset using the SQL dialect.

Steps To Reproduce

Using a SQL dialect, consider a change set like:

-- liquibase formatted sql

-- changeset anthonyr:create-table-AW_TEST-1 runOnChange:true
create or replace table AW_TEST (
  ID int not null autoincrement,
  valueDate date not null
)
-- rollback

When I test a rollback, Liquibase throws an error:

Unexpected error running Liquibase: No inverse to liquibase.change.core.RawSQLChange created

I am legitimately OK with an empty rollback. Note that I don’t really see a SQL Example in the documentation.

Actual Behavior

When I test a rollback, Liquibase throws an error:

Unexpected error running Liquibase: No inverse to liquibase.change.core.RawSQLChange created

Expected/Desired Behavior

When I test a rollback, Liquibase should basically do nothing for this changeset since the rollback is empty.

Thank you @filipelautert! Yes I should’ve mentioned that I saw the workaround in this thread and it worked for me 👍🏻 glad to hear it will be released soon.

@rorysaur sory for that, seems the documentation team jumped the gun on this one - this feature will be released in Liquibase 4.18 . Meanwhile you need to use an workaround as -- rollback select 'N/A' or something like that .
