HQL Validator

Purpose-built tool for HQL query validation, enabling static analysis of Hibernate queries without a live database. It tokenizes the input, applies HQL grammar rules, and flags syntax errors, invalid paths, and alias inconsistencies. It can optionally simulate entity attribute checks when minimal metadata is provided. This helps developers catch issues early and improves query reliability across Hibernate-based codebases. The tool produces a structured report detailing issue type, location, and suggested fixes, making it suitable for local development and CI pipelines. By isolating structure and semantics from runtime execution, teams can enforce coding standards and reduce debugging time in data access layers. The validator focuses on the most common failure modes in HQL: improper joins, ambiguous path expressions, and unsupported functions. It is particularly valuable for migrations, code reviews, and quick sanity checks before integration testing. Unique value lies in its lightweight, metadata-assisted mode and its ability to surface actionable guidance without requiring a database connection.
