docs: Retrieves table of results for the query. May block if the query must be executed first.
  
      Args:
        use_cache: whether to use cached results or not. Ignored if append is specified.
        dialect : {'legacy', 'standard'}, default 'legacy'
            'legacy' : Use BigQuery's legacy SQL dialect.
            'standard' : Use BigQuery's standard SQL (beta), which is
            compliant with the SQL 2011 standard.
        billing_tier: Limits the billing tier for this job. Queries that have resource
            usage beyond this tier will fail (without incurring a charge). If unspecified, this
            will be set to your project default. This can also be used to override your
            project-wide default billing tier on a per-query basis.
      Returns:
        A QueryResultsTable containing the result set.
      Raises:
        Exception if the query could not be executed or query response was malformed.
