   .. py:method:: field_to_bigquery(field)

      Convert a DBAPI field to BigQuery schema format.


   .. py:method:: convert_type(value, schema_type, **kwargs)

      Takes a value from Oracle db, and converts it to a value that's safe for
      JSON/Google Cloud Storage/BigQuery.

      * Datetimes are converted to UTC seconds.
      * Decimals are converted to floats.
      * Dates are converted to ISO formatted string if given schema_type is
        DATE, or UTC seconds otherwise.
      * Binary type fields are converted to integer if given schema_type is
        INTEGER, or encoded with base64 otherwise. Imported BYTES data must
        be base64-encoded according to BigQuery documentation:
        https://cloud.google.com/bigquery/data-types

      :param value: Oracle db column value
      :param schema_type: BigQuery data type
