QueryPilot

Schema-aware natural-language-to-SQL workflow with validation and explainability.

August 5, 2024ยท 6 min read

Problem

Text-to-SQL assistants often produce unsafe or invalid queries when they lack schema context and execution safeguards.

Solution

Built a schema-aware generation pipeline that reads live metadata, produces SQL from user intent, validates before execution, and returns both query output and human-readable SQL explanations.

Workflow

  1. Inspect live database schema and relationships.
  2. Build constrained prompt context for query generation.
  3. Validate generated SQL before any execution step.
  4. Return results plus explanation for user verification.

Key Outcome

By combining schema grounding and a validation gate, QueryPilot balances usability with safer execution behavior.
