sql-sidekick

A simple SQL assistant (WIP) Turn ★ into ⭐ (top-right corner) if you like the project! 🙏

Motivation

Historically, it’s common for data to be stored in Databases, democratizing insight generation.
Enable a helpful assistant to help write complex queries across different database dialects with acceptable efficient execution accuracy (not just matching accuracy)
Push to derive consistent generation without errors using smaller OSS models to save on compute costs.
Provide a toolkit for users to mix and match different model sizes to optimize compute cost - e.g., smaller models for generation, remote bigger models for syntax correction or spell correction …
Build a smart search engine for Databases/structured data, Text to SQL as a Natural Language interface (NLI) for data analysis

Key Features

An interactive UI to capture feedback along with a python-client and CLI mode.
Ability for auto DB schema generation for input data using custom input format.
Support for in-context learning (ICL) pipeline with RAG support to control hallucination
Guardrails: to check for SQL injections via SELECT statements, e.g., SELECT * FROM SleepStudy WHERE user_id = 11 OR 1=1;
Entity mapping/Schema linking: Ability to build memory for mapping business context to the data schema dynamically; **Note: currently enabled only via CLI, others WIP.
Ability to save the chat history of query/answer pairs for future reference and improvements.
Self-correction loop back: Validates syntactic correction of generation. **Note: Self-correction is currently enabled for all openAI GPT models. WIP for other OSS models.
Integration with different database dialects - currently, SQLite/Postgres(might be broken temporarily)/Databricks is enabled. WIP to add support for Duckdb and others.
Debug mode: Ability to evaluate/modify and validate SQL query against the configured database via UI
Recommend sample questions: Often, given a dataset, we are unsure what to ask. To come around this problem, we have enabled the ability to generate recommendations for possible questions.

Installation

Requirements

This project requires Python version to be within the range "3.8.1" to "3.10.0". You can check your Python version by running the following command in your terminal:

python --version

If your Python version is not within the specified range, you may need to update or downgrade it.

Dev

1. git clone git@github.com:h2oai/sql-sidekick.git
2. cd sql-sidekick
3. make setup
4. source ./.sidekickvenv/bin/activate
5. poetry install (in case there is an error, try `poetry update` before `poetry install`)
6. python sidekick/prompter.py

Usage

Dialect: postgres
- docker pull postgres (will pull the latest version)
- docker run --rm --name pgsql-dev -e POSTGRES_PASSWORD=abc -p 5432:5432 postgres

Default: sqlite
Step:
- Download and install .whl --> s3://sql-sidekick/releases/sql_sidekick-0.0.3-py3-none-any.whl
- python3 -m venv .sidekickvenv
- source .sidekickvenv/bin/activate
- python3 -m pip install sql_sidekick-0.0.3-py3-none-any.whl

Start

`sql-sidekick`

Welcome to the SQL Sidekick! I am an AI assistant that helps you with SQL
queries. I can help you with the following:
  0. Generate input schema:
  `sql-sidekick configure generate_schema configure generate_schema --data_path "./sample_passenger_statisfaction.csv" --output_path "./table_config.jsonl"`

  1. Configure a local database(for schema validation and syntax checking):
  `sql-sidekick configure db-setup -t "<local_dir_path_to_>/table_info.jsonl"` (e.g., format --> https://github.com/h2oai/sql-sidekick/blob/main/examples/telemetry/table_info.jsonl)

  2. Ask a question: `sql-sidekick query -q "avg Gpus" -s "<local_dir_path_to_>/samples.csv"` (e.g., format --> https://github.com/h2oai/sql-sidekick/blob/main/examples/telemetry/samples.csv)

  3. Learn contextual query/answer pairs: `sql-sidekick learn add-samples` (optional)

  4. Add context as key/value pairs: `sql-sidekick learn update-context` (optional)

Options:
  --version  Show the version and exit.
  --help     Show this message and exit.

Commands:
  configure  Helps in configuring local database.
  learn      Helps in learning and building memory.
  query      Asks question and returns SQL
