Methods

#cache=

def cache=(value)

Specifies to look in the query cache for results.

Parameter
  • value (Boolean) — Whether to look for the result in the query cache. The query cache is a best-effort cache that will be flushed whenever tables in the query are modified. The default value is true. For more information, see query caching.

#cancel

def cancel()

#clustering_fields=

def clustering_fields=(fields)

Sets the list of fields on which data should be clustered.

Only top-level, non-repeated, simple-type fields are supported. When you cluster a table using multiple columns, the order of columns you specify is important. The order of the specified columns determines the sort order of the data.

BigQuery supports clustering for both partitioned and non-partitioned tables.

See #clustering_fields, Table#clustering_fields and Table#clustering_fields=.

Parameter
  • fields (Array<String>) — The clustering fields. Only top-level, non-repeated, simple-type fields are supported.
Example 
require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
destination_table = dataset.table "my_destination_table",
                                  skip_lookup: true

job = dataset.query_job "SELECT * FROM my_table" do |job|
  job.table = destination_table
  job.time_partitioning_type = "DAY"
  job.time_partitioning_field = "dob"
  job.clustering_fields = ["last_name", "first_name"]
end

job.done? #=> true

#create=

def create=(value)

Sets the create disposition for creating the query results table.

create new tables. The default value is needed.

The following values are supported:

  • needed - Create the table if it does not exist.
  • never - The table must already exist. A 'notFound' error is raised if the table does not exist.
Parameter
  • value (String) — Specifies whether the job is allowed to

#create_session=

def create_session=(value)

Sets the create_session property. If true, creates a new session, where session id will be a server generated random id. If false, runs query with an existing #session_id=, otherwise runs query in non-session mode. The default value is false.

value is false.

Parameter
  • value (Boolean) — The create_session property. The default

#dataset=

def dataset=(value)

#dry_run=

def dry_run=(value)
Alias Of: #dryrun=

Sets the dry run flag for the query job.

Parameter
  • value (Boolean) — If set, don't actually run this job. A valid query will return a mostly empty response with some processing statistics, while an invalid query will return the same error it would if it wasn't a dry run..

#dryrun=

def dryrun=(value)
Aliases

Sets the dry run flag for the query job.

Parameter
  • value (Boolean) — If set, don't actually run this job. A valid query will return a mostly empty response with some processing statistics, while an invalid query will return the same error it would if it wasn't a dry run..

#encryption=

def encryption=(val)

job = bigquery.query_job "SELECT 1;" do |job|
  job.table = dataset.table "my_table", skip_lookup: true
  job.encryption = encrypt_config
end

#external=

def external=(value)

Sets definitions for external tables used in the query.

Parameter
  • value (Hash<String|Symbol, External::DataSource>) — A Hash that represents the mapping of the external tables to the table names used in the SQL query. The hash keys are the table names, and the hash values are the external table objects.

#flatten=

def flatten=(value)

Flatten nested and repeated fields in legacy SQL queries.

Parameter
  • value (Boolean) — This option is specific to Legacy SQL. Flattens all nested and repeated fields in the query results. The default value is true. large_results parameter must be true if this is set to false.

#labels=

def labels=(value)

Sets the labels to use for the job.

Parameter
  • value (Hash) —

    A hash of user-provided labels associated with the job. You can use these to organize and group your jobs.

    The labels applied to a resource must meet the following requirements:

    • Each resource can have multiple labels, up to a maximum of 64.
    • Each label must be a key-value pair.
    • Keys have a minimum length of 1 character and a maximum length of 63 characters, and cannot be empty. Values can be empty, and have a maximum length of 63 characters.
    • Keys and values can contain only lowercase letters, numeric characters, underscores, and dashes. All characters must use UTF-8 encoding, and international characters are allowed.
    • The key portion of a label must be unique. However, you can use the same key with multiple resources.
    • Keys must start with a lowercase letter or international character.

#large_results=

def large_results=(value)

Allow large results for a legacy SQL query.

Parameter
  • value (Boolean) — This option is specific to Legacy SQL. If true, allows the query to produce arbitrarily large result tables at a slight cost in performance. Requires table parameter to be set.

#legacy_sql=

def legacy_sql=(value)

Sets the query syntax to legacy SQL.

Parameter
  • value (Boolean) — Specifies whether to use BigQuery's legacy SQL dialect for this query. If set to false, the query will use BigQuery's standard SQL dialect. Optional. The default value is false.

#location=

def location=(value)

Sets the geographic location where the job should run. Required except for US and EU.

Parameter
  • value (String) — A geographic location, such as "US", "EU" or "asia-northeast1". Required except for US and EU.

  query.location = "EU"
end

#maximum_bytes_billed=

def maximum_bytes_billed=(value)

Sets the maximum bytes billed for the query.

Parameter
  • value (Integer) — Limits the bytes billed for this job. Queries that will have bytes billed beyond this limit will fail (without incurring a charge). Optional. If unspecified, this will be set to your project default.

#params=

def params=(params)

Sets the query parameters. Standard SQL only.

Use #set_params_and_types to set both params and types.

Parameter
  • params (Array, Hash) — Standard SQL only. Used to pass query arguments when the query string contains either positional (?) or named (@myparam) query parameters. If value passed is an array ["foo"], the query must use positional query parameters. If value passed is a hash { myparam: "foo" }, the query must use named query parameters. When set, legacy_sql will automatically be set to false and standard_sql to true.
