#bignumeric(name, description: nil, mode: :nullable, policy_tags: nil, precision: nil, scale: nil, default_value_expression: nil) ⇒ Object

Adds a bignumeric number field to the schema. BIGNUMERIC is a decimal type with fixed precision and scale. Precision is the number of digits that the number contains. Scale is how many of these digits appear after the decimal point. It supports:

Precision: 76.76 (the 77th digit is partial) Scale: 38 Min: -5.7896044618658097711785492504343953926634992332820282019728792003956564819968E+38 Max: 5.7896044618658097711785492504343953926634992332820282019728792003956564819967E+38

This type can represent decimal fractions exactly, and is suitable for financial calculations.

See Schema#bignumeric

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
job = dataset.load_job "my_table", "gs://abc/file" do |schema|
  schema.bignumeric "total_cost", mode: :required
end

#clustering_fields=(fields) ⇒ Object

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 Google::Cloud::Bigquery::LoadJob#clustering_fields, Table#clustering_fields and Table#clustering_fields=.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"

gcs_uri = "gs://my-bucket/file-name.csv"
load_job = dataset.load_job "my_new_table", gcs_uri do |job|
  job.time_partitioning_type  = "DAY"
  job.time_partitioning_field = "dob"
  job.schema do |schema|
    schema.timestamp "dob", mode: :required
    schema.string "first_name", mode: :required
    schema.string "last_name", mode: :required
  end
  job.clustering_fields = ["last_name", "first_name"]
end

load_job.wait_until_done!
load_job.done? #=> true

Parameters:

  • fields (Array<String>) —

    The clustering fields. Only top-level, non-repeated, simple-type fields are supported.

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
job = dataset.load_job "my_table", "gs://abc/file" do |schema|
  schema.record "cities_lived", mode: :repeated do |cities_lived|
    cities_lived.geography "location", mode: :required
    cities_lived.integer "number_of_years", mode: :required
  end
end

Add field with default value.

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
job = dataset.load_job "my_table", "gs://abc/file" do |schema|
  schema.geography "location", default_value_expression: "ST_GEOGPOINT(-122.084801, 37.422131)"
end

Parameters:

  • name (String) —

    The field name. The name must contain only letters ([A-Za-z]), numbers ([0-9]), or underscores (_), and must start with a letter or underscore. The maximum length is 128 characters.

  • description (String) (defaults to: nil) —

    A description of the field.

  • mode (Symbol) (defaults to: :nullable) —

#hive_partitioning_mode=(mode) ⇒ Object

Sets the mode of hive partitioning to use when reading data. The following modes are supported:

  1. auto: automatically infer partition key name(s) and type(s).
  2. strings: automatically infer partition key name(s). All types are interpreted as strings.
  3. custom: partition key schema is encoded in the source URI prefix.

Not all storage formats support hive partitioning. Requesting hive partitioning on an unsupported format will lead to an error. Currently supported types include: avro, csv, json, orc and parquet.

See #format= and #hive_partitioning_source_uri_prefix=.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"

gcs_uri = "gs://cloud-samples-data/bigquery/hive-partitioning-samples/autolayout/*"
source_uri_prefix = "gs://cloud-samples-data/bigquery/hive-partitioning-samples/autolayout/"
load_job = dataset.load_job "my_new_table", gcs_uri do |job|
  job.format = :parquet
  job.hive_partitioning_mode = :auto
  job.hive_partitioning_source_uri_prefix = source_uri_prefix
end

load_job.wait_until_done!
load_job.done? #=> true

Parameters:

  • mode (String, Symbol) —

    The mode of hive partitioning to use when reading data.

end

#hive_partitioning_source_uri_prefix=(source_uri_prefix) ⇒ Object

Sets the common prefix for all source uris when hive partition detection is requested. The prefix must end immediately before the partition key encoding begins. For example, consider files following this data layout:

gs://bucket/path_to_table/dt=2019-01-01/country=BR/id=7/file.avro
gs://bucket/path_to_table/dt=2018-12-31/country=CA/id=3/file.avro

When hive partitioning is requested with either AUTO or STRINGS mode, the common prefix can be either of gs://bucket/path_to_table or gs://bucket/path_to_table/ (trailing slash does not matter).

See #hive_partitioning_mode=.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"

gcs_uri = "gs://cloud-samples-data/bigquery/hive-partitioning-samples/autolayout/*"

#schema(replace: false) {|schema| ... } ⇒ Google::Cloud::Bigquery::Schema

Returns the table's schema. This method can also be used to set, replace, or add to the schema by passing a block. See Schema for available methods.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
job = dataset.load_job "my_table", "gs://abc/file" do |j|
  j.schema do |s|
    s.string "first_name", mode: :required
    s.record "cities_lived", mode: :repeated do |r|

    end
  end
end

Parameters:

  • replace (Boolean) (defaults to: false) —

    Whether to replace the existing schema with the new schema. If true, the fields will replace the existing schema. If false, the fields will be added to the existing schema. When a table already contains data, schema changes must be additive. Thus, the default value is false.

Yields:

  • (schema) —

    a block for setting the schema

Yield Parameters:

  • schema (Schema) —

    the object accepting the schema

end

#schema_update_options=(new_options) ⇒ Object

Sets the schema update options, which allow the schema of the destination table to be updated as a side effect of the load job if a schema is autodetected or supplied in the job configuration. Schema update options are supported in two cases: when write disposition is WRITE_APPEND; when write disposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema. One or more of the following values are specified:

  • ALLOW_FIELD_ADDITION: allow adding a nullable field to the schema.
  • ALLOW_FIELD_RELAXATION: allow relaxing a required field in the original schema to nullable.

Parameters:

  • new_options (Array<String>) —
