def df(chunk_size: int = None, **kwargs: None) -> Optional[DataFrame]

[view_source]

Fetches the results as data frame. For large queries the results may be chunked

Fetches the results into a data frame. The default implementation uses helpers in pandas.io.sql to generate Pandas data frame. This function will try to use native data frame generation for particular destination. For BigQuery: QueryJob.to_dataframe is used. For duckdb: `DuckDBPyConnection.df'

Arguments:

  • chunk_size int, optional - Will chunk the results into several data frames. Defaults to None
  • **kwargs Any - Additional parameters which will be passed to native data frame generation function.

Returns:

  • Optional[DataFrame] - A data frame with query results. If chunk_size > 0, None will be returned if there is no more data in results
