Table of Contents
Overview
Implement robust transaction management with ACID compliance, concurrency control, and error handling. Covers isolation levels, locking strategies, and deadlock resolution.
When to Use
- ACID transaction implementation
- Concurrent data modification handling
- Isolation level selection
- Deadlock prevention and resolution
- Transaction timeout configuration
- Distributed transaction coordination
- Financial transaction safety
Quick Start
Simple Transaction:
-- Start transaction
BEGIN;
-- Multiple statements
UPDATE accounts SET balance = balance - 100 WHERE id = 1;
UPDATE accounts SET balance = balance + 100 WHERE id = 2;
-- Commit changes
COMMIT;
-- Or rollback
ROLLBACK;
