- Injection Attacks:Raw queries can be prone to injection attacks if not handled properly. Using a query builder mitigates this risk.
- Human Error: Building complex queries manually can lead to errors. Using a library helps ensure that your queries are correct and optimized.
- Maintainability: As your queries grow in complexity, managing them through a builder makes the code more maintainable and easier to understand.
