STRUCT<x STRING, y ARRAY>: {
type_kind="STRUCT",
struct_type={
fields=[
{name="x", type={type_kind="STRING"}},

}
RANGE: {type_kind="RANGE", range_element_type="DATETIME"}
Parameters | |
---|---|
Name | Description |
type_kind |
typing.Optional[google.cloud.bigquery.enums.StandardSqlTypeNames]
The top level type of this field. Can be any standard SQL data type, e.g. INT64, DATE, ARRAY. |
array_element_type |
typing.Optional[StandardSqlDataType]
The type of the array's elements, if type_kind is ARRAY. |
struct_type |
typing.Optional[StandardSqlStructType]
The fields of this struct, in order, if type_kind is STRUCT. |
range_element_type |
typing.Optional[StandardSqlDataType]
The type of the range's elements, if type_kind is RANGE. |
StandardSqlField
StandardSqlField(
name: typing.Optional[str] = None,
type: typing.Optional[
google.cloud.bigquery.standard_sql.StandardSqlDataType
