# SQLchat
|
| 2 |
+
|
| 3 |
+
This project is a **SQL Chatbot** built with **LangChain** and **Streamlit**, designed to generate SQL queries and execute queries
|
| 4 |
+
based on database table schemas and structure. The chatbot can interact with users to understand their requirements
|
| 5 |
+
and translate them into SQL queries, leveraging relational database information provided via URI and schema definitions.
|
| 6 |
+
|
| 7 |
+
## Features
|
| 8 |
+
|
| 9 |
+
- **SQL Query Generator**: Automatically generates SQL queries based on user inputs and database structure.
|
| 10 |
+
- **SQL Query Execution**: Automatically executes SQL queries generated by chatbot.
|
| 11 |
+
- **Interactive Chat Interface**: Built with Streamlit for a user-friendly conversational experience.
|
| 12 |
+
- **Database Schema Integration**: Parses table schemas from a database URI to provide accurate SQL generation capabilities.
|
| 13 |
+
- **Customizable LLM Configuration**: Supports various large language models (LLMs) for generating responses.
|
| 14 |
+
|
| 15 |
+
## Installation
|
| 16 |
+
|
| 17 |
+
1. Clone the repository:
|
| 18 |
+
|
| 19 |
+
```bash
|
| 20 |
+
git clone https://github.com/arthiondaena/SQLchat.git
|
| 21 |
+
cd SQLchat
|
| 22 |
+
```
|
| 23 |
+
|
| 24 |
+
2. Set up a virtual environment:
|
| 25 |
+
|
| 26 |
+
```bash
|
| 27 |
+
python -m venv venv
|
| 28 |
+
source venv/bin/activate # On Windows: venv\Scripts\activate
|
| 29 |
+
```
|
| 30 |
+
|
| 31 |
+
3. Install dependencies:
|
| 32 |
+
|
| 33 |
+
```bash
|
| 34 |
+
pip install -r requirements.txt
|
| 35 |
+
```
|
| 36 |
+
|
| 37 |
+
## Usage
|
| 38 |
+
|
| 39 |
+
Run the application using Streamlit:
|
| 40 |
+
|
| 41 |
+
```bash
|
| 42 |
+
streamlit run app.py
|
| 43 |
+
```
|
| 44 |
+
|
| 45 |
+
This will launch the chatbot interface in your default web browser. The chatbot can then process user inputs and generate SQL queries based on the database schema.
|
| 46 |
+
|
| 47 |
+
## Setup
|
| 48 |
+
|
| 49 |
+
1. **Configure Database Connection**:
|
| 50 |
+
- Set up the `URI` configuration in the streamlit app to connect to your relational database.
|
| 51 |
+
- Ensure the database has the necessary permissions to allow schema queries.
|
| 52 |
+
|
| 53 |
+
2. **Table Schemas**:
|
| 54 |
+
- The chatbot extracts table structures and schemas from the database for generating SQL queries. Make sure the database contains valid schema definitions.
|
| 55 |
+
|
| 56 |
+
3. **API Key Configuration**:
|
| 57 |
+
- Provide your Groq API key for LLM integration within the script.
|
| 58 |
+
|
| 59 |
+
4. **System Prompt Customization**:
|
| 60 |
+
- Adjust the instructions as per your specific SQL generation use case.
|
| 61 |
+
- The chatbot can remember upto last 4 conversations.
|
| 62 |
+
|
| 63 |
+
## Features in Detail
|
| 64 |
+
|
| 65 |
+
1. **SQL Query Generation**:
|
| 66 |
+
- The chatbot uses relational database schemas to intelligently generate SQL queries.
|
| 67 |
+
- Supports basic and complex queries tailored to the provided database structure.
|
| 68 |
+
|
| 69 |
+
2. **Database Schema Utilization**:
|
| 70 |
+
- Extracts table information (columns, types, relationships) from the connected database.
|
| 71 |
+
- Leverages this knowledge to produce highly precise SQL queries.
|
| 72 |
+
|
| 73 |
+
3. **Customizable Model Prompts**:
|
| 74 |
+
- Custom system prompts and instructions can be added to suit diverse database use cases.
|
| 75 |
+
|
| 76 |
+
## Example Workflow
|
| 77 |
+
1. Connect the chatbot to your database by specifying the database URI.
|
| 78 |
+
2. Provide the chatbot with your SQL query requirement in plain language (e.g., "Fetch the top 10 customers by revenue").
|
| 79 |
+
3. The chatbot generates and returns an accurate SQL query based on the schema.
