        [--description=DESCRIPTION] [--expiration=EXPIRATION]
        [--relax-columns=[FIELD_NAME,...]]

          | --add-columns-file=PATH_TO_FILE] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION

    table or view.

    the value and tags columns in a table with ID my-other-table in dataset
    my-other-dataset:

        $ gcloud alpha bq tables update my-other-table \
            --dataset my-other-dataset --relax-columns name,tags

     --relax-columns=[FIELD_NAME,...]
        A comma-separated list of field names in the current schema that should
        have their mode changed from REQUIRED to NULLABLE.

        For more details on updating and managing BigQuery schemas see:
        https://cloud.google.com/bigquery/docs/managing-table-schemas

     Specify changes to the table schema.

     At most one of these can be specified:

       --add-columns=[FIELD_NAME=FIELD_TYPE,...]
          A comma-separated list of entries of the form FIELD_NAME[=FIELD_TYPE]
          specifying field names and types for the columns being added to the
          table. FIELD_TYPE defaults to string if not present. Possible
          FIELD_TYPES are string, integer, float, boolean, record, and
          timestamp.

          For more details on BigQuery schemas see:
          https://cloud.google.com/bigquery/docs/schemas.

       --add-columns-file=PATH_TO_FILE
          The name of a JSON file containing a single object containing an
          array each element of which is an object with properties name, type,
          and, optionally a mode (one of: NULLABLE or REPEATED), specifying the
          columns to be added to the table. If mode is omitted the default is
          'NULLABLE'.

          For example: { 'schema': [ { 'name': 'field1', 'type': 'string',
          'mode': 'REQUIRED' }, { 'name': 'field2', 'type': 'integer', 'mode':
          'REPEATED' }, [ { 'name': 'fieldN', 'type': TYPE, ['mode': MODE] }
          ... ] ] }

          For more details on BigQuery schemas see:

          Use a full or relative path to a local file containing the value of
          add_columns_file.
