# Chat-DBT
Interact with your database using human queries through OpenAI GPT.
https://user-images.githubusercontent.com/24897252/233864066-2110a65e-3337-40c2-a1e5-3756e21d6ed6.mp4
## Features
- Supported databases: PostgreSQL, ClickHouse
- Both Command line and Web interfaces
- Pipe from/to standard input/output
- Keeps the history between queries (unless specified otherwise)
- Use OpenAI to auto-correct SQL errors
- Multiple result formats (table, JSON, CSV)
## Getting started
```sh
npm i -g chat-dbt
chat-dbt --database postgres://username:password@localhost:5432/postgres --key openai-key
```
## Usage
All the available options can be shown using `chat-dbt --help`
### Command-line interface
```sh
chat-dbt --database postgres://username:password@localhost:5432/postgres --key openai-key
```
### Web interface
```sh
chat-dbt web --database postgres://username:password@localhost:5432/postgres --key openai-key
```
https://user-images.githubusercontent.com/24897252/233865764-2a8c4716-f052-47f5-9e48-0ec3a4cc818f.mp4
### Database connection string
#### ClickHouse
```sh
chat-dbt --database clickhouse://username:[email protected]?secure=true
```
The `secure` option will translate into an `https` entrypoint. Its default is `false`, which corresponds to `http`.
No other ClickHouse option is supported, please file an issue or create a pull request if you need some of them.
### Adapting context between queries
By default, Chat-DBT keeps a history of previous exchanges with OpenAI. Although this feature provides more context to OpenAI and enables queries using previous results, it uses more tokens and is therefore more costly. If you plan to extract a significant amount of data to send back to OpenAI, you may reach the token limit quickly. Here's an example of how context can be reused between queries:
https://user-images.githubusercontent.com/24897252/235167307-8d5fe81e-567a-43be-8300-852930ce9238.mp4
You can either disable the history with the `--history-mode=none` option, or only keep the previous queries without sending their database result with the `--history-mode=queries` option. Please note that the previous query will however always be sent when you asked to retry a query that failed.
```sh
chat-dbt --history-mode=[all|none|queries]
```
### Handling of errors
Sometimes OpenAI's response may include an incorrect SQL query that fails. In such cases, you have the following options:
- Retry: In this case, the error will be sent back to OpenAI, and it will be asked to correct its response.
- Edit prompt: You can reformulate the request to OpenAI for it to adjust its response.
- Edit SQL: You can manually change the SQL query generated by OpenAI to correct its error and then execute it.
It is possible to automatically request corrections from OpenAI while sending errors back to it. This feature is deactivated by default, but you can enable it by using the `--auto-correct nb-attempts` flag, where `nb-attempts` is the number of attempts OpenAI will have to solve the error.
Each attempt is iterative and builds upon the previous ones, so OpenAI is supposed to take the context into account to reach a successful query eventually.
```sh
chat-dbt --auto-correct 3
```
### Working with input and output files
You can use a file as a source of a batch of instructions, that you can pipe through chat-dbt, for instance, given the following `instructions.txt` file:
```sh
list authors
add a famous author from the 20th century
list authors
```
You can then execute the instructions with:
```sh
cat instructions.txt | chat-dbt
```
It is also possible to define which part of the output should be redirected to stderr, stdout, or nowhere, with the `--output-sql`, `--output-result` and `--output-info` options. For instance, the following instruction will output the SQL query to `stderr`, and the SQL result into `authors.csv`:
```sh
echo "list authors" | chat-dbt \
--output-sql stderr \
--output-result stdout \
--output-info none \
--format csv > authors.csv
```
### Environment variables
```sh
export DB_CONNECTION_STRING=postgres://username:password@localhost:5432/postgres
export OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
export OPENAI_ORGANIZATION=org-xxxxxxxxxxxxxxxxxxxxxxxx
chat-dbt
```
Chat-DBT will also read the secrets mentioned above from a `.env` file, if it exists:
```
DB_CONNECTION_STRING=postgres://username:password@localhost:5432/postgres
OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
OPENAI_ORGANIZATION=org-xxxxxxxxxxxxxxxxxxxxxxxx
```
You can also pass a different `.env` file name as an option:
```sh
chat-dbt --env .env.custom
```
### Choose another OpenAI model
The OpenAI model is set to `gpt-4` by default. You can choose another chat model with the `--model` option, for instance:
```sh
chat-dbt --model gpt-3.5-turbo
```
You can have a look at the [list of compatible chat completion models in the OpenAI documentation](https://platform.openai.com/docs/models/model-endpoint-compatibility).
### Ask for confirmation before executing the SQL query
You may not feel comfortable executing a query before previewing it. To preview the SQL query and confirm before running it, use the `--confirm` option. This option prompts you for confirmation and allows you to modify the SQL query if needed before its execution.
```sh
chat-dbt --confirm
```
### Change the format of the result
By default, Chat-DBT renders the results as a table. You can however output the result in CSV or JSON, in passing the `--format` option:
```sh
chat-dbt --format json
chat-dbt --format csv
```
## Development
```sh
# Clone the repository
git clone https://github.com/plmercereau/chat-dbt
cd chat-dbt
# Install Node dependencies
pnpm i
# Create a .env.local file
cp .env.local.example .env.local
# Then, edit the .env.local file to fill your OpenAI API key and organisation
# Start the demo database
docker-compose up -d
```
### Develop the CLI
```sh
pnpm run dev:cli
```
### Develop the Web interface
```sh
pnpm run dev:web
```
