end

#create_session ⇒ Boolean Also known as: create_session?

Optional. If true, creates a new session using a randomly generated session_id. If false, runs query with an existing session_id passed in ConnectionProperty, otherwise runs query in non-session mode. The session location will be set to QueryRequest.location if it is present, otherwise it's set to the default location based on existing routing logic. Corresponds to the JSON property createSession

Returns:

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)

def job_creation_mode
  @job_creation_mode
end

#job_timeout_ms ⇒ Fixnum

Optional. Job timeout in milliseconds. If this time limit is exceeded, BigQuery will attempt to stop a longer job, but may not always succeed in canceling it before the job completes. For example, a job that takes more than 60 seconds to complete has a better chance of being stopped than a job that takes 10 seconds to complete. This timeout applies to the query even if a job does not need to be created. Corresponds to the JSON property jobTimeoutMs

Returns:

  • (Fixnum) 


8078

# File 'lib/google/apis/bigquery_v2/classes.rb', line 8099

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) 


8108

8110
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8108

def max_results
  @max_results
end

#max_slots ⇒ Fixnum

Optional. A target limit on the rate of slot consumption by this query. If set to a value > 0, BigQuery will attempt to limit the rate of slot consumption by this query to keep it below the configured limit, even if the query is eligible for more slots based on fair scheduling. The unused slots will be available for other jobs and queries to use. Note: This feature is not yet generally available. Corresponds to the JSON property maxSlots

Returns:

  • (Fixnum) 


8118
8119
8120
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8118

def max_slots
  @max_slots
end

#maximum_bytes_billed ⇒ Fixnum

Optional. Limits the bytes billed for this query. Queries with bytes billed above this limit will fail (without incurring a charge). If unspecified, the project default is used. Corresponds to the JSON property maximumBytesBilled

Returns:

  • (Fixnum)

end

#query ⇒ String

Required. A query string to execute, using Google Standard SQL or legacy SQL syntax. Example: "SELECT COUNT(f1) FROM myProjectId.myDatasetId.myTableId". Corresponds to the JSON property query

Returns:

  • (String)

# File 'lib/google/apis/bigquery_v2/classes.rb', line 8148

def query_parameters
  @query_parameters
end

#request_id ⇒ String

Optional. 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 another request, all parameters in the request that may affect the result 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)

8172
8173
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8171

def request_id
  @request_id
end

#reservation ⇒ String

Optional. The reservation that jobs.query request would use. User can specify a reservation to execute the job.query. The expected format is projects/ project/locations/location/reservations/reservation`. Corresponds to the JSON propertyreservation`

Returns:

  • (String) 


8178
8179
8180
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8178

def reservation
  @reservation
end

#timeout_ms ⇒ Fixnum

Optional. Optional: Specifies the maximum amount of time, in milliseconds, that the client is willing to wait for the query to complete. By default, this limit is 10 seconds (10,000 milliseconds). If the query is complete, the jobComplete field in the response is true. If the query has not yet completed, jobComplete is false. You can request a longer timeout period in the timeoutMs field. However, the call is not guaranteed to wait for the specified timeout; it typically returns after around 200 seconds (200,000 milliseconds), even if the query is not complete. If jobComplete is false, you can continue to wait for the query to complete by calling the getQueryResults method until the jobComplete field in the getQueryResults response is true. Corresponds to the JSON property timeoutMs

Returns:

  • (Fixnum) 


8192
8193
8194
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8192

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 uses BigQuery's GoogleSQL. 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) 


8201
8202
8203
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8201

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) 


8209
8210
8211
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8209

def use_query_cache
  @use_query_cache
end

#write_incremental_results ⇒ Boolean Also known as: write_incremental_results?

Optional. This is only supported for SELECT query. If set, the query is allowed to write results incrementally to the temporary result table. This may incur a performance penalty. This option cannot be used with Legacy SQL. This feature is not yet available. Corresponds to the JSON property writeIncrementalResults

Returns:

  • (Boolean) 


8218
8219
8220
 
# File 'lib/google/apis/bigquery_v2/classes.rb', line 8218

def write_incremental_results
  @write_incremental_results
