Gcloud::Bigquery::Job

Job ↑

Represents a generic Job that may be performed on a Table.

See Managing Jobs, Datasets, and Projects for an overview of BigQuery jobs, and the Jobs API reference for details.

The subclasses of Job represent the specific BigQuery job types: CopyJob, ExtractJob, LoadJob, and QueryJob.

A job instance is created when you call Gcloud::Bigquery::Project#query_job, Gcloud::Bigquery::Dataset#query_job, Gcloud::Bigquery::Table#copy, Gcloud::Bigquery::Table#extract, Gcloud::Bigquery::Table#load, or Gcloud::Bigquery::View#data.

require "gcloud"

gcloud = Gcloud.new
bigquery = gcloud.bigquery

q = "SELECT COUNT(word) as count FROM publicdata:samples.shakespeare"
job = bigquery.query_job q

loop do
  break if job.done?
  sleep 1
  job.refresh!
end

if job.failed?
  puts job.error
else
  puts job.query_results.first
end
