This is the official repository for the paper "MAC-SQL: A Multi-Agent Collaborative Framework for Text-to-SQL".

In this paper, we propose a multi-agent collaborative Text-to-SQL framework MAC-SQL, which comprises three agents: the Selector, the Decomposer, and the Refiner.

• [2024.11] Our work has been accepted by COLING 2025 conference paper version. Welcome to cite this paper version.
• [2024.04] We have updated the sql-llama-instruct-v0.5.jsonl and training scripts in training_scripts dir of this project. Please check it out.Download the sql-llama-data.zip from Baidu Dsik or Google Drive. Unzip sql-llama-data.zip and get the data dir, which contains sql-llama-instruct-v0.5.jsonl (3375 instances).
• [2024.04] We have updated the SQL-Llama-v0.5 model and data.zip (update dev_gold_schema.json in bird and spider) The download links of the updated data are available on Baidu Disk and Google Drive.
• [2024.02] We have updated the paper, with updates mainly focusing on experiments and framework details, check it out! link.
• [2023.12] We have updated the paper, with updates mainly focusing on the title, abstract, introduction, some details, and appendix. In addition, we give some bad case examples on bad_cases folder, check it out!
• [2023.12] We released our first version paper, code. Check it out!

1. Config your local environment.

conda create -n macsql python=3.9 -y
conda activate macsql
pip install -r requirements.txt
python -c "import nltk; nltk.download('punkt')"

Note: we use openai==0.28.1, which use openai.ChatCompletion.create to call api.

2. Edit openai config at core/api_config.py, and set related environment variables of Azure OpenAI API.

Currently, we use gpt-4-1106-preview (128k version) by default, which is 2.5 times less expensive than the gpt-4 (8k) on average.

export OPENAI_API_BASE="YOUR_OPENAI_API_BASE"
export OPENAI_API_KEY="YOUR_OPENAI_API_KEY"

In order to prepare the data more quickly, I have packaged the files including the databases of the BIRD dataset and the Spider dataset into data.zip and uploaded them. All files were downloaded on December 19, 2023, ensuring they are the latest version at that moment. The download links are available on Baidu Disk and Google Drive(update on 2024-04-22).

After downloading the data.zip file, you should delete the existing data folder in the project directory and replace it with the unzipped data folder from data.zip.

The run script will first run 5 examples in Spider to check environment. You should open code comments for different usage.

• run.sh for Linux/Mac OS
• run.bat for Windows OS

For SQL execution demo, you can use app_bird.py or app_spider.py to get the execution result of your SQL query.

cd ./scripts
python app_bird.py
python app_spider.py

If occur error /bin/bash^M: bad interpreter in Linux, use sed -i -e 's/\r$//' run.sh to solve it.

We evaluate our method on both BIRD dataset and Spider dataset.

EX: Execution Accuracy(%)

VES: Valid Efficiency Score(%)

Refer to our paper for the details.

Download the SQL-Llama(current v0.5 version) and follow the SQL-Llama-deployment.md to deploy.

Uncomment the MODEL_NAME = 'CodeLlama-7b-hf' in core/api_config.py to set the global model and comment other MODEL_NAME = xxx lines.

Uncomment the export OPENAI_API_BASE='http://0.0.0.0:8000/v1' in run.sh to set the local model api base.

Then, run run.sh to start your local inference.
