# File 'lib/google/apis/bigquery_v2/classes.rb', line 5110

def connection_properties
  @connection_properties
end

#create_session ⇒ Boolean Also known as: create_session?

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 passed in ConnectionProperty, otherwise runs query in non-session mode. Corresponds to the JSON property createSession

Returns:

  • (Boolean)

def create_session
  @create_session
end

#default_dataset ⇒ Google::Apis::BigqueryV2::DatasetReference

[Optional] Specifies the default datasetId and projectId to assume for any unqualified table names in the query. If not set, all table names in the query string must be qualified in the format 'datasetId.tableId'. Corresponds to the JSON property defaultDataset

Returns:

# File 'lib/google/apis/bigquery_v2/classes.rb', line 5125

def default_dataset
  @default_dataset
end

#dry_run ⇒ Boolean Also known as: dry_run?

[Optional] If set to true, BigQuery doesn't run the job. Instead, if the query is valid, BigQuery returns statistics about the job such as how many bytes would be processed. If the query is invalid, an error returns. The default value is false. Corresponds to the JSON property dryRun

Returns:

  • (Boolean)

# File 'lib/google/apis/bigquery_v2/classes.rb', line 5139

def kind

end

#labels ⇒ Hash<String,String>

The labels associated with this job. You can use these to organize and group your jobs. Label keys and values can be no longer than 63 characters, can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. Label values are optional. Label keys must start with a letter and each label in the list must have a different key. Corresponds to the JSON property labels

Returns:

def location
  @location
end

#max_results ⇒ Fixnum

[Optional] The maximum number of rows of data to return per page of results. Setting this flag to a small value such as 1000 and then paging through results might improve reliability when the query result set is large. In addition to this limit, responses are also limited to 10 MB. By default, there is no maximum row count, and only the byte limit applies. Corresponds to the JSON property maxResults

Returns:

  • (Fixnum)

# File 'lib/google/apis/bigquery_v2/classes.rb', line 5163

def max_results
  @max_results
end

#maximum_bytes_billed ⇒ Fixnum

[Optional] Limits the bytes billed for this job. Queries that will have bytes billed beyond this limit will fail (without incurring a charge). If unspecified, this will be set to your project default. Corresponds to the JSON property maximumBytesBilled

Returns:

  • (Fixnum)

# File 'lib/google/apis/bigquery_v2/classes.rb', line 5170

def maximum_bytes_billed
  @maximum_bytes_billed
end

#parameter_mode ⇒ String

Standard SQL only. Set to POSITIONAL to use positional (?) query parameters or to NAMED to use named (@myparam) query parameters in this query. Corresponds to the JSON property parameterMode

Returns:

  • (String)

end

#query ⇒ String

[Required] A query string, following the BigQuery query syntax, of the query to execute. Example: "SELECT count(f1) FROM [myProjectId:myDatasetId.myTableId] ". Corresponds to the JSON property query

Returns:

  • (String)

def query_parameters
  @query_parameters
end

#request_id ⇒ String

A unique user provided identifier to ensure idempotent behavior for queries. Note that this is different from the job_id. It has the following properties:

  1. It is case-sensitive, limited to up to 36 ASCII characters. A UUID is recommended. 2. Read only queries can ignore this token since they are nullipotent by definition. 3. For the purposes of idempotency ensured by the request_id, a request is considered duplicate of another only if they have the same request_id and are actually duplicates. When determining whether a request is a duplicate of the previous request, all parameters in the request that may affect the behavior are considered. For example, query, connection_properties, query_parameters, use_legacy_sql are parameters that affect the result and are considered when determining whether a request is a duplicate, but properties like timeout_ms don't affect the result and are thus not considered. Dry run query requests are never considered duplicate of another request. 4. When a duplicate mutating query request is detected, it returns: a. the results of the mutation if it completes successfully within the timeout. b. the running operation if it is still in progress at the end of the timeout. 5. Its lifetime is limited to 15 minutes. In other words, if two requests are sent with the same request_id, but more than 15 minutes apart, idempotency is not guaranteed. Corresponds to the JSON property requestId

Returns:

  • (String)

5218
5219
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 5217

def request_id
  @request_id
end

#timeout_ms ⇒ Fixnum

[Optional] How long to wait for the query to complete, in milliseconds, before the request times out and returns. Note that this is only a timeout for the request, not the query. If the query takes longer to run than the timeout value, the call returns without any results and with the 'jobComplete' flag set to false. You can call GetQueryResults() to wait for the query to complete and read the results. The default value is 10000 milliseconds (10 seconds). Corresponds to the JSON property timeoutMs

Returns:

  • (Fixnum)

# File 'lib/google/apis/bigquery_v2/classes.rb', line 5227

def timeout_ms
  @timeout_ms
end

#use_legacy_sql ⇒ Boolean Also known as: use_legacy_sql?

Specifies whether to use BigQuery's legacy SQL dialect for this query. The default value is true. If set to false, the query will use BigQuery's standard SQL: https://cloud.google.com/bigquery/sql-reference/ When useLegacySql is set to false, the value of flattenResults is ignored; query will be run as if flattenResults is false. Corresponds to the JSON property useLegacySql

Returns:

  • (Boolean)

5238
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 5236

def use_legacy_sql
  @use_legacy_sql
end

#use_query_cache ⇒ Boolean Also known as: use_query_cache?

[Optional] 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. Corresponds to the JSON property useQueryCache

Returns:

  • (Boolean)
