  • Most SQL validators only report the first syntax error with generic messages, lacking actionable guidance.
  • Common shortcomings include reporting only the first error, vague messages, no suggested fixes, and no side-by-side diff.
  • A better SQL validator should report multiple errors, provide exact locations, explain issues, suggest fixes, and allow side-by-side comparison.
  • Example validation highlights errors like missing commas, mixed aggregates, incorrect ORDER BY placement, column mismatches, and quoting issues.
  • Existing validators like RunSQL, Aiven, and SQLValidator fail to address multiple errors or provide correct fixes.
  • The proposed validator supports multiple SQL dialects and integrates inline annotations and explanations.
