### Windows MSI

[Download the MSI installer](https://dbc.columnar.tech/latest/dbc-latest-x64.msi)

For more installation options, see the [installation docs](docs/getting_started/installation.md).

## Getting Started

Search for available drivers:

```sh
dbc search
```

Install a driver:

```sh
dbc install snowflake
```

Use it with Python:

```sh
pip install "adbc-driver-manager>=1.8.0"
```

```python
import adbc_driver_manager.dbapi as adbc

with adbc.connect(
    driver="snowflake",
    db_kwargs={
        "username": "USER",
        "password": "PASS",
        "adbc.snowflake.sql.account": "ACCOUNT-IDENT",
        # ... other connection options
    },
) as con, con.cursor() as cursor:
    cursor.execute("SELECT * FROM CUSTOMER LIMIT 5")
    print(cursor.fetch_arrow_table())
```

You can also manage drivers in a project using a [driver list](docs/guides/driver_list.md). And you can store connection options in a [connection profile](https://arrow.apache.org/adbc/current/format/connection_profiles.html) instead of in your code.

For more details, see the [dbc documentation](https://docs.columnar.tech/dbc) and the [ADBC Quickstarts](https://github.com/columnar-tech/adbc-quickstarts).
