Cascade Left Database Schema Out of Sync
Application crashes because JPA expects columns that don't exist in database, or database has columns that entity model doesn't know about. Cascade generated entity changes without creating corresponding database migrations.
This typically manifests as 'column not found' errors or unexpected NULL values in queries.
Error Messages You Might See
Common Causes
- Cascade added fields to entity model without creating migration script
- Cascade deleted entity fields without removing database columns
- Cascade renamed fields in code but database column names unchanged
- Data type changes (Integer to String) not reflected in migration
How to Fix It
Generate migration script manually to align schema with entity model. Use database diff tools to identify discrepancies. Review Cascade's entity changes against migration files. Create new migration with ALTER TABLE statements for changed columns.

How do I generate a migration for schema changes?
Create V{next_number}__describe_changes.sql with appropriate ALTER TABLE, ADD COLUMN, DROP COLUMN statements.
Can I auto-generate migrations?
Tools like Liquibase can generate changelogs, but manual review is recommended for safety.
