Abstract: Converting natural language queries into SQL queries is a crucial challenge
in both industry and academia, aiming to increase access to databases and
large-scale applications. This work examines how in-context learning and
chain-of-thought can be utilized to develop a robust solution for text-to-SQL
systems. We propose SQL-of-Thought: a multi-agent framework that decomposes the
Text2SQL task into schema linking, subproblem identification, query plan
generation, SQL generation, and a guided correction loop. Unlike prior systems
that rely only on execution-based static correction, we introduce
taxonomy-guided dynamic error modification informed by in-context learning.
SQL-of-Thought achieves state-of-the-art results on the Spider dataset and its
variants, combining guided error taxonomy with reasoning-based query planning.
