job_id is optional now that the client library can generate it, so probably can be removed from this sample

We can remove this job_id generation.

We can remove this job_id, too.

We should use the return value for result instead of getting the table after this.

Use the rows from the return value for result here.

Let the client library generate the job ID.
| job_config.query_parameters = query_params | ||
| query_job = client.query(query, job_config=job_config, job_id=job_id) | ||
|
|

Use the return value from result.

Love it! It's much nicer to show accessing the specific columns in this sample.

We can actually pass max_results to list_rows now.
Use max_results in list_rows.
