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
- Removed BEGIN/START TRANSACTION statement
- COMMIT missing, changes never persisted
- ROLLBACK not called on error, partial changes remain
- Mixing transactions with non-transactional queries
- 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.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently 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.
