Cursor database

Database Transaction Not Atomic After Changes

After Cursor refactored your database transaction code, operations that should succeed or fail together are now failing partially. Data consistency is compromised.

Transaction wrapping or commit/rollback logic was broken.

Error Messages You Might See

Data inconsistency Partial transaction applied Duplicate entries Inconsistent state

Common Causes

  1. Removed BEGIN/START TRANSACTION statement
  2. COMMIT missing, changes never persisted
  3. ROLLBACK not called on error, partial changes remain
  4. Mixing transactions with non-transactional queries
  5. Auto-commit enabled, breaking transaction isolation

How to Fix It

Wrap multi-step operations: BEGIN; query1; query2; COMMIT; or ROLLBACK on error. Use ORM transaction helpers: await sequelize.transaction(async t => { ... }). Always rollback on error. Test with failures injected.

Frequently Asked Questions

What's ACID?

Atomicity (all or nothing), Consistency (valid state), Isolation (concurrent ops don't interfere), Durability (persisted). Transactions guarantee ACID.

How do I handle transaction errors?

Wrap in try/catch. Catch errors rollback transaction. Finally commit if success. ORM abstracts this.
