> I am attempting to query an [external data source|https://cloud.google.com/bigquery/external-data-sources], a MySQL database that is exposed via the BigQuery API, located in the EU region. I have the following format query string:
> {code:python}
> query = """
>     SELECT * 
>     FROM EXTERNAL_QUERY("my-project-one-253518.eu.external-source", 
>     "SELECT * FROM my schema.mytable;");
>     """
> {code}
> And the following pipeline instantiation:
> {code:python}
>     pcoll = p | "Load " + name >> beam.io.Read(
>         beam.io.BigQuerySource(query=query, use_standard_sql=True)
>     )
> {code}
> When run this, I see the following output:
> {code:python}
