QuackDB.Result (quackdb v0.3.0)

Copy Markdown View Source

Normalized query result.

The shape mirrors what Ecto.Adapters.SQL expects from DBConnection-backed drivers: rows and num_rows are always present, while columns, connection_id, messages, and metadata keep Quack-specific result information available.
