dbc Skill

Install and manage drivers for the user with the dbc command line program.

Installing dbc

If the user does not have

dbc

available, try to install it for them.

Prefer installing it with with these commands, in order of preference, if the tool is available:

If
```
uv
```
is available:
```
uv tool install dbc
```
If
```
pipx
```
is available:
```
pipx install dbc
```

Otherwise install dbc with the appropriate command for their operating system:

macOS & Linux: Run

curl -LsSf https://dbc.columnar.tech/install.sh | sh

Windows: Run

powershell -ExecutionPolicy ByPass -c "irm https://dbc.columnar.tech/install.ps1 | iex"

Most Important Commands

dbc install <driver>

- Install a driver (e.g.,

dbc install snowflake

)

```
dbc search [pattern]
```
- Search for a driver using a pattern (e.g.,
```
dbc search sql
```
). Also lists installed drivers.
```
dbc info <driver>
```
- Get driver details

Run

dbc --help

to learn about other commands.

Project Workflow

For reproducible driver management, prefer using this workflow over

dbc install

:

```
dbc init
```
- Create a
```
dbc.toml
```
file
```
dbc add <driver>
```
- Add drivers to the list (supports version constraints like
```
dbc add "postgresql>=13.0"
```
)
```
dbc sync
```
- Install all drivers and create
```
dbc.lock
```

Using Drivers

Drivers installed with dbc must be used with an ADBC driver manager. dbc cannot load a driver or query a data source directly. Don't install drivers from any other source like PyPI, prefer drivers installed with dbc always.
