示例1: createTable

  /**
   * Create a table given a tableId or configuration object.
   *
   * @see [Tables: insert API Documentation]{@link https://cloud.google.com/bigquery/docs/reference/v2/tables/insert}
   *
   * @param {string} id Table id.
   * @param {object} [options] See a
   *     [Table resource](https://cloud.google.com/bigquery/docs/reference/v2/tables#resource).
   * @param {string|object} [options.schema] A comma-separated list of name:type
   *     pairs. Valid types are "string", "integer", "float", "boolean", and
   *     "timestamp". If the type is omitted, it is assumed to be "string".
   *     Example: "name:string, age:integer". Schemas can also be specified as a
   *     JSON array of fields, which allows for nested and repeated fields. See
   *     a [Table resource](http://goo.gl/sl8Dmg) for more detailed information.
   * @param {function} [callback] The callback function.
   * @param {?error} callback.err An error returned while making this request
   * @param {Table} callback.table The newly created table.
   * @param {object} callback.apiResponse The full API response.
   * @returns {Promise}
   *
   * @example
   * const BigQuery = require('@google-cloud/bigquery');
   * const bigquery = new BigQuery();
   * const dataset = bigquery.dataset('institutions');
   *
   * const tableId = 'institution_data';
   *
   * const options = {
   *   // From the data.gov CSV dataset (http://goo.gl/kSE7z6):
   *   schema: 'UNITID,INSTNM,ADDR,CITY,STABBR,ZIP,FIPS,OBEREG,CHFNM,...'
   * };
   *
   * dataset.createTable(tableId, options, (err, table, apiResponse) => {});
   *
   * //-
   * // If the callback is omitted, we'll return a Promise.
   * //-
   * dataset.createTable(tableId, options).then((data) => {
   *   const table = data[0];
   *   const apiResponse = data[1];
   * });
   */

      datasetId: this.id,
      projectId: this.bigQuery.projectId,
      tableId: id,
    };

      {
        method: 'POST',

示例3: getQueryResults

  /**
   * @callback QueryResultsCallback
   * @param {?Error} err An error returned while making this request.
   * @param {array} rows The results of the job.
   */
  /**
   * @callback ManualQueryResultsCallback
   * @param {?Error} err An error returned while making this request.
   * @param {array} rows The results of the job.
   * @param {?object} nextQuery A pre-made configuration object for your next
   *     request. This will be `null` if no additional results are available.
   *     If the query is not yet complete, you may get empty `rows` and
   *     non-`null` `nextQuery` that you should use for your next request.
   * @param {object} apiResponse The full API response.
   */

   *     the `nextQuery` argument of your callback.
   * @param {number} [options.startIndex] Zero-based index of the starting row.
   * @param {number} [options.timeoutMs] How long to wait for the query to
   *     complete, in milliseconds, before returning. Default is to return

   *     will fail with a `TIMEOUT` error.

   *     callback function. If `autoPaginate` is set to false a
   *     {@link ManualQueryResultsCallback} should be used.
