Benchmarking the Text-to-SQL Capability of Large Language Models: A Comprehensive Evaluation
arxiv(2024)
摘要
Large Language Models (LLMs) have emerged as a powerful tool in advancing the
Text-to-SQL task, significantly outperforming traditional methods.
Nevertheless, as a nascent research field, there is still no consensus on the
optimal prompt templates and design frameworks. Additionally, existing
benchmarks inadequately explore the performance of LLMs across the various
sub-tasks of the Text-to-SQL process, which hinders the assessment of LLMs'
cognitive capabilities and the optimization of LLM-based solutions.To address
the aforementioned issues, we firstly construct a new dataset designed to
mitigate the risk of overfitting in LLMs. Then we formulate five evaluation
tasks to comprehensively assess the performance of diverse methods across
various LLMs throughout the Text-to-SQL process.Our study highlights the
performance disparities among LLMs and proposes optimal in-context learning
solutions tailored to each task. These findings offer valuable insights for
enhancing the development of LLM-based Text-to-SQL systems.
