end

#default_value_expression ⇒ String

Optional. A SQL expression to specify the default value for this field. It can only be set for top level fields (columns). You can use struct or array expression to specify default value for the entire struct or array. The valid SQL expressions are: - Literals for all data types, including STRUCT and ARRAY.

  • Following functions: - CURRENT_TIMESTAMP - CURRENT_TIME - CURRENT_DATE - CURRENT_DATETIME - GENERATE_UUID - RAND - SESSION_USER - ST_GEOGPOINT - Struct or array composed with the above allowed functions, for example, [CURRENT_DATE( ), DATE '2020-01-01'] Corresponds to the JSON property defaultValueExpression

Returns:

  • (String)

#fields ⇒ Array<Google::Apis::BigqueryV2::TableFieldSchema>

end

#max_length ⇒ Fixnum

[Optional] Maximum length of values of this field for STRINGS or BYTES. If max_length is not specified, no maximum length constraint is imposed on this field. If type = "STRING", then max_length represents the maximum UTF-8 length of strings in this field. If type = "BYTES", then max_length represents the maximum number of bytes in this field. It is invalid to set this field if type ≠ "STRING" and ≠ "BYTES". Corresponds to the JSON property maxLength

Returns:

  • (Fixnum)

def max_length
  @max_length
end

#mode ⇒ String

[Optional] The field mode. Possible values include NULLABLE, REQUIRED and REPEATED. The default value is NULLABLE. Corresponds to the JSON property mode

Returns:

  • (String)

# File 'lib/google/apis/bigquery_v2/classes.rb', line 7466

def mode
  @mode
end

#name ⇒ String

[Required] The field name. The name must contain only letters (a-z, A-Z), numbers (0-9), or underscores (_), and must start with a letter or underscore. The maximum length is 300 characters. Corresponds to the JSON property name

Returns:

  • (String)

Corresponds to the JSON property policyTags

Returns:

# File 'lib/google/apis/bigquery_v2/classes.rb', line 7478

def policy_tags
  @policy_tags
end

#precision ⇒ Fixnum

[Optional] Precision (maximum number of total digits in base 10) and scale ( maximum number of digits in the fractional part in base 10) constraints for values of this field for NUMERIC or BIGNUMERIC. It is invalid to set precision or scale if type ≠ "NUMERIC" and ≠ "BIGNUMERIC". If precision and scale are not specified, no value range constraint is imposed on this field insofar as values are permitted by the type. Values of this NUMERIC or BIGNUMERIC field must be in this range when: - Precision (P) and scale (S) are specified: [-10P- S + 10-S, 10P-S - 10-S] - Precision (P) is specified but not scale (and thus scale is interpreted to be equal to zero): [-10P + 1, 10P - 1]. Acceptable values for precision and scale if both are specified: - If type = "NUMERIC": 1 ≤ precision - scale ≤ 29 and 0 ≤ scale ≤ 9. - If type = "BIGNUMERIC": 1 ≤ precision - scale ≤ 38 and 0 ≤ scale ≤ 38. Acceptable values for precision if only precision is specified but not scale (and thus scale is interpreted to be equal to zero): - If type = "NUMERIC": 1 ≤ precision ≤ 29. - If type = " BIGNUMERIC": 1 ≤ precision ≤ 38. If scale is specified but not precision, then it is invalid. Corresponds to the JSON property precision

Returns:

  • (Fixnum)

def scale
  @scale
end

#type ⇒ String

[Required] The field data type. Possible values include STRING, BYTES, INTEGER, INT64 (same as INTEGER), FLOAT, FLOAT64 (same as FLOAT), NUMERIC, BIGNUMERIC, BOOLEAN, BOOL (same as BOOLEAN), TIMESTAMP, DATE, TIME, DATETIME, INTERVAL, RECORD (where RECORD indicates that the field contains a nested schema) or STRUCT (same as RECORD). Corresponds to the JSON property type

Returns:

  • (String)
