Example

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
routine = dataset.create_routine "my_routine" do |r|
  r.routine_type = "SCALAR_FUNCTION"
  r.language = :SQL
  r.body = "(SELECT SUM(IF(elem.name = \"foo\",elem.val,null)) FROM UNNEST(arr) AS elem)"
  r.arguments = [
    Google::Cloud::Bigquery::Argument.new(
      name: "arr",
      argument_kind: "FIXED_TYPE",
      data_type: Google::Cloud::Bigquery::StandardSql::DataType.new(
