عرض عملي: تأسيس خط أساس لـ Shop باستخدام Flyway وإضافة V2

خطوة بخطوة

1. Add Flyway; copy the current schema.sql into V1__baseline.sql.
2. Set spring.jpa.hibernate.ddl-auto=validate.
3. Start on a fresh empty database; show the history table.
4. For the existing database, enable baseline on migrate with baseline version 1 and start; V1 is skipped.
5. Planned mistake: edit V1 after it ran; show the checksum error, revert, and add V2__add_sku.sql with a backfill instead.
6. Compare both databases: same state.
