method createJob

createJob: {
    (options: JobOptions): Promise<JobResponse>;
    (options: JobOptions, callback: JobCallback): void;

• Creates a job. Typically when creating a job you'll have a very specific task in mind. For this we recommend one of the following methods:

  - BigQuery.createQueryJob - Table#createCopyJob - Table#createCopyFromJob - Table#createExtractJob - Table#createLoadJob

  However in the event you need a finer level of control over the job creation, you can use this method to pass in a raw Job resource object.

  See Jobs Overview See Jobs: insert API Documentation

  Parameter options

  Object in the form of a Job resource;

  Parameter

  {string} [options.jobId] Custom job id.

  Parameter

  {string} [options.jobPrefix] Prefix to apply to the job id.

  Parameter

  {string} [options.location] The geographic location of the job. Required except for US and EU.

  Parameter callback

  The callback function.

  Parameter

  {?error} callback.err An error returned while making this request.

  Parameter

      query: {
        query: 'SELECT url FROM `publicdata.samples.github_nested` LIMIT 100'
      }
    }

      // Error handling omitted.
    }
  
    job.getQueryResults(function(err, rows) {});

createQueryJob: {
    (options: Query | string): Promise<JobResponse>;

  {Table} [options.destination] The table to save the query's results to. If omitted, a new table will be created.

  Parameter

  {boolean} [options.dryRun] If set, don't actually run this job. A valid query will update the job with processing statistics. These can be accessed via job.metadata.
