A case study using sewage metagenomic data for assessment of text-to-SQL capabilities in large language models
This study evaluates the text-to-SQL capabilities of large language models (LLMs) using a complex database of sewage metagenomic data. It highlights the potential for simplifying database interaction for non-experts, while also identifying crucial limitations regarding ambiguity and the need for human oversight. The integration of LLMs with direct database connectivity significantly enhances query generation, statistical analysis, and visualization.

ChatGPT-4o Outperforms Other Models
GPT-4o Leading Model in AccuracyThe latest ChatGPT-4o model demonstrated substantial performance improvements over ChatGPT 3.5 and Anthropic models in generating accurate SQL queries.
Addressing Ambiguous Queries with SewageGPT
A key challenge in Text-to-SQL is handling ambiguous or unanswerable questions. Our SewageGPT tool demonstrated this, requiring careful prompting and expert oversight.
Challenge: When users ask questions for which relevant data is absent or unclear in the database, LLMs can generate partially correct, incorrect, or misleading answers. For example, queries about 'yellowish color' in samples or 'chicken farms' were unanswerable due to lack of specific metadata.
Solution: Providing detailed database schema, column descriptions, and background information significantly improves accuracy. Furthermore, encouraging users to first query the LLM about database contents helps them formulate answerable questions. Human oversight remains critical for validating complex or ambiguous queries to avoid incorrect conclusions.
