@param [String] project_id Identifier for a BigQuery project. If not
present, the default project for the credentials is used.
@param [String, Hash, Google::Auth::Credentials] credentials The path to
the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See {Bigquery::Credentials})
@param [String, Array<String>] scope The OAuth 2.0 scopes controlling the
set of resources and operations that the connection can access. See [Using OAuth 2.0 to Access Google APIs](https://developers.google.com/identity/protocols/OAuth2). The default scope is: * `https://www.googleapis.com/auth/bigquery`
@param [Integer] retries Number of times to retry requests on server
error. The default value is `5`. Optional.
@param [Integer] timeout Default timeout to use in requests. Optional.
@return [Google::Cloud::Bigquery::Project]
@example
require "google/cloud" bigquery = Google::Cloud.bigquery dataset = bigquery.dataset "my_dataset" table = dataset.table "my_table"
# File lib/google-cloud-bigquery.rb, line 112 def self.bigquery project_id = nil, credentials = nil, scope: nil, retries: nil, timeout: nil require "google/cloud/bigquery" Google::Cloud::Bigquery.new project_id: project_id, credentials: credentials, scope: scope, retries: retries, timeout: timeout end
Public Instance Methods

@param [String, Array<String>] scope The OAuth 2.0 scopes controlling the
set of resources and operations that the connection can access. See [Using OAuth 2.0 to Access Google APIs](https://developers.google.com/identity/protocols/OAuth2). The default scope is: * `https://www.googleapis.com/auth/bigquery`
@param [Integer] retries Number of times to retry requests on server
error. The default value is `5`. Optional.
@param [Integer] timeout Default request timeout in seconds. Optional.
@return [Google::Cloud::Bigquery::Project]
@example
require "google/cloud" gcloud = Google::Cloud.new bigquery = gcloud.bigquery dataset = bigquery.dataset "my_dataset" table = dataset.table "my_table" data = table.data # Iterate over the first page of results data.each do |row| puts row[:name] end # Retrieve the next page of results data = data.next if data.next?
@example The default scope can be overridden with the `scope` option:
require "google/cloud" gcloud = Google::Cloud.new platform_scope = "https://www.googleapis.com/auth/cloud-platform" bigquery = gcloud.bigquery scope: platform_scope
# File lib/google-cloud-bigquery.rb, line 73 def bigquery scope: nil, retries: nil, timeout: nil Google::Cloud.bigquery @project, @keyfile, scope: scope, retries: (retries || @retries), timeout: (timeout || @timeout) end
