# is it possible for @liquibase to auto-generate changeset Id's? The ID field in \[DATABASECHANGELOG\] is NVARCHAR(255), which means there's plenty of space for e.g. GUID? #LiquibaseHelp

Can you share your changelog and how you are executing Liquibase? I tried creating an XML changelog with no id field on any of the changesets and run the update command from the console and got what I expected to see - an error:

Unexpected error running Liquibase: cvc-complex-type.4: Attribute ‘id’ must appear on element ‘changeSet’.
