# sqrl duckdb

> Open DuckDB CLI (optionally with UI) initialized for the project

The `duckdb` command launches the DuckDB command-line tool.

## Usage

```bash wrap theme={null}
sqrl duckdb [options]
```

## Options

In addition to the [global options](/references/cli/index#global-options), this command supports:

| Option | Description                |
| ------ | -------------------------- |
| `--ui` | Launch the local DuckDB UI |

## Examples

Open DuckDB CLI:

```bash theme={null}
sqrl duckdb
```

Open the local DuckDB UI:

```bash theme={null}
sqrl duckdb --ui
```

## Notes

* Exit the DuckDB CLI with `.exit`
* If a `duckdb_init.sql` file exists, it will be written to `target/duckdb_init.sql` (with additional DuckDB commands) and loaded.
* The DuckDB CLI must be installed for this command to work. If the DuckDB CLI is not installed, install it from `https://duckdb.org/install`
