Developer's schemagate library outperforms other methods for text-to-SQL table selection

By PulseAugur Editorial · [1 sources] ·

A developer compared four methods for selecting relevant database tables for text-to-SQL prompts, finding that their open-source library, schemagate, significantly outperformed other approaches. Using the same MiniLM model, schemagate successfully identified all necessary tables in tests on Spider 2.0 and BIRD datasets, whereas the embedding-based method missed tables multiple times. This improved selection comes at a modest cost of 8-11% more tokens, largely due to the inclusion of tables needed for joins. AI

IMPACT Improves efficiency and accuracy for text-to-SQL applications by optimizing table selection.

    I compared four ways to pick tables for a text-to-SQL prompt

    <p>Every text-to-SQL prompt carries a schema. Send all of it and you pay for every table on every call. Send a few and you risk leaving out the one the question needs. So how you pick the tables matters.</p> <p>I tested four ways on the same questions, with no model calls at all:…
