Schema-Aware Localisation (SAL): Live Schema Grounding and Hallucination Validation for Oracle NL2SQL
TL;DR
Schema-Aware Localisation (SAL) enhances Oracle NL2SQL by integrating live schema grounding, significantly reducing SQL execution errors from 97.6% to 2.6%. SAL achieves 62.6% execution-grounded truth without manual schema curation.
✦ Why It Matters
Implement SAL to improve SQL query accuracy and reduce execution errors in your Oracle database applications.
Key Takeaways
- Integrate SAL to enhance SQL generation from natural language.
- Utilize live schema mapping to reduce execution errors.
- Leverage the Hallucination Index for SQL validation.
- Achieve higher execution-grounded truth without manual schema curation.
How It Works
SAL queries the USER_TAB_COLUMNS catalog to create a live schema map, ensuring that the LLM has accurate context for generating SQL. It selects relevant tables for each query and uses the Hallucination Index to validate and correct generated SQL against the live database schema.
