Effi-SQL
Update 2026-06-12
We release Effi-SQL, a dataset suite for SQL efficiency optimization.
This collection includes:
- Effi-SQL Benchmark: a benchmark for evaluating SQL efficiency optimization methods.
- Diff-SQL Training Dataset: training data used by Diff-SQL, including data for the Patch Generator and Constraint Aligner.
Dataset Fields
Effi-SQL Benchmark
- id: A unique identifier for each benchmark instance.
- db: The database name.
- base_sql: The original slow SQL query.
- optimized_sql: The human-verified optimized SQL query.
- base_time: Execution time of the original SQL query.
- fast_time: Execution time of the optimized SQL query.
- base_explain_analyze: Query execution plan (QEP) output for the original SQL query.
- optimized_explain_analyze: Query execution plan (QEP) output for the optimized SQL query.
- difficulty: The difficulty label of the benchmark instance.
Diff-SQL Training Dataset
- instance_id: A unique identifier for each training instance.
- prompt: The model input prompt, including the slow SQL query, relevant database information, and the query execution plan of the slow SQL query.
- response: The target response, including optimization or refinement reasoning and the target patch.
- db: The database name of the slow SQL query.
- base_sql: The original slow SQL query.
- optimized_sql: The optimized SQL query used as the reference target.
