title: How can i get the result of an query from BigQuery in Airflow, and attach it into an email auto-send to me
body: <p>I want to use dynamic time <code>{{ macros.ds_add(ds, 0) }}</code>, so <code>pandas_gbq.read_gbq</code> doesn't work.</p>
  
  <p>I also used the <code>get_pandas_df</code> of <code>BigQueryHook</code>, it showed <code>'BigQueryPandasConnector'</code> object has no attribute <code>'http_error'</code>, the document says that I need to override <code>DbApiHook</code> method, but I don't know how.</p>
  
  <p>And is there any solution for this issue? Appreciate for your help, guys.</p>
