0.42.0

You can now use all_columns at the root. For example:

await Band.select(
    Band.all_columns(),
    Band.manager.all_columns()
).run()

You can also exclude certain columns if you like:

await Band.select(
    Band.all_columns(exclude=[Band.id]),
    Band.manager.all_columns(exclude=[Band.manager.id])
).run()
