Reliable Answers for Recurring Questions: Boosting Text-to-SQL Accuracy with Template Constrained Decoding
Summary: Builds reusable NL–SQL templates from labeled workloads and uses a fine-tuned NLI selector to match/reject incoming queries. Enforces chosen template via partitioned grammar-constrained decoding for valid, efficient SQL, yielding up to +36% exec accuracy over ICL and 2.2× lower latency on matched queries.
