Manage database transactions for data consistency. Use when implementing ACID compliance, handling concurrency, or managing transaction isolation levels.
Implement robust transaction management with ACID compliance, concurrency control, and error handling. Covers isolation levels, locking strategies, and deadlock resolution.
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;
