StandardSqlDataType(
    type_kind: typing.Optional[
        google.cloud.bigquery.enums.StandardSqlTypeNames
    ] = StandardSqlTypeNames.TYPE_KIND_UNSPECIFIED,
    array_element_type: typing.Optional[
        google.cloud.bigquery.standard_sql.StandardSqlDataType
    ] = None,
    struct_type: typing.Optional[
        google.cloud.bigquery.standard_sql.StandardSqlStructType
    ] = None,
)

The type of a variable, e.g., a function argument.

See: https://cloud.google.com/bigquery/docs/reference/rest/v2/StandardSqlDataType

Examples:

INT64: {type_kind="INT64"}
ARRAY: {type_kind="ARRAY", array_element_type="STRING"}
STRUCT<x STRING, y ARRAY>: {
    type_kind="STRUCT",
    struct_type={
        fields=[
            {name="x", type={type_kind="STRING"}},
            {
                name="y",
                type={type_kind="ARRAY", array_element_type="DATE"}
            }
        ]
    }
}

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.

StandardSqlField

StandardSqlField(
    name: typing.Optional[str] = None,
    type: typing.Optional[
        google.cloud.bigquery.standard_sql.StandardSqlDataType
    ] = None,
)

A field or a column.

See: https://cloud.google.com/bigquery/docs/reference/rest/v2/StandardSqlField

Parameters
Name	Description
`name`	`typing.Optional[str]` The name of this field. Can be absent for struct fields.
`type`	`typing.Optional[google.cloud.bigquery.standard_sql.StandardSqlDataType]` The type of this parameter. Absent if not explicitly specified. For example, CREATE FUNCTION statement can omit the return type; in this case the output parameter does not have this "type" field).

StandardSqlStructType

StandardSqlStructType(
    fields: typing.Optional[
        typing.Iterable[google.cloud.bigquery.standard_sql.StandardSqlField]
    ] = None,
)

Type of a struct field.

See: https://cloud.google.com/bigquery/docs/reference/rest/v2/StandardSqlDataType#StandardSqlStructType

Parameter
Name	Description
`fields`	`typing.Optional[typing.Iterable[google.cloud.bigquery.standard_sql.StandardSqlField]]` The fields in this struct.

StandardSqlTableType

StandardSqlTableType(
    columns: typing.Iterable[google.cloud.bigquery.standard_sql.StandardSqlField],
)

A table type.

See: https://cloud.google.com/workflows/docs/reference/googleapis/bigquery/v2/Overview#StandardSqlTableType

Parameter
Name	Description
`columns`	`typing.Iterable[google.cloud.bigquery.standard_sql.StandardSqlField]` The columns in this table type.
