Spider (complete)

The Spider text-to-SQL dataset with its questions, the DDL and metadata of every database, and the SQLite files, in the same layout as birdsql_complete_devset.

Splits

Split	Questions	Databases
train	8,656	146
validation	1,034	20
test	2,147	40

No database appears in more than one split.

Structure

questions: question_id (unique within the split), source (spider or others), source_index (position in the original file), db_id, question, sql, question_toks, query_toks, query_toks_no_value and sql_parsed (the original parsed query, as JSON text).

schemas: one row per database, in the split that uses it: db_id, schema_raw (DDL from sqlite_master) and the original metadata table_names, table_names_original, column_names, column_names_original, column_types, primary_keys and foreign_keys (nested fields as JSON text).

databases/<db_id>/<db_id>.sqlite: the SQLite file of every database.

Usage

import json
from datasets import load_dataset

repo = "EuricoGVP/spider_sql_complete"
questions = load_dataset(repo, "questions", split="train")
schemas = {row["db_id"]: row for row in load_dataset(repo, "schemas", split="train")}

row = questions[0]
print(schemas[row["db_id"]]["schema_raw"])
print(row["question"], row["sql"])
print(json.loads(row["sql_parsed"]))

Changes from the original release

• train merges train_spider.json and train_others.json, the official training set; dev.json is validation.
• query is renamed to sql, and the parsed sql structure to sql_parsed.
• Metadata comes from tables.json (with the 2020 fixes for scholar and formula_1) and from test_tables.json for the test-only databases.
• Only the .sqlite files are included, taken from test_database, which holds all 206 databases.
• Queries that do not compile in SQLite were removed:

Split	Source	Source index	Database
train	spider	3153	assets_maintenance
train	spider	4513	document_management
train	spider	4514	document_management

Notes

• schema_raw is the DDL exactly as stored in each database, with inconsistent quoting and formatting.
• The formula_1 database in train shares its domain and tables with the formula_1 database of the BIRD dev set. Exclude it when training models that are evaluated on BIRD.
