stored in a table cell or returned from an SQL query.
Attributes
| Name | Description |
| code |
google.cloud.spanner_v1.types.TypeCode
Required. The TypeCode][google.spanner.v1.TypeCode] for
this type.
|
| array_element_type |
google.cloud.spanner_v1.types.Type
If code][google.spanner.v1.Type.code] ==
ARRAY][google.spanner.v1.TypeCode.ARRAY], then
array_element_type is the type of the array elements.
|
| struct_type |
google.cloud.spanner_v1.types.StructType
If code][google.spanner.v1.Type.code] ==
STRUCT][google.spanner.v1.TypeCode.STRUCT], then
struct_type provides type information for the struct's
fields.
|
| type_annotation |
google.cloud.spanner_v1.types.TypeAnnotationCode
The TypeAnnotationCode][google.spanner.v1.TypeAnnotationCode]
that disambiguates SQL type that Spanner will use to
represent values of this type during query processing. This
is necessary for some type codes because a single
TypeCode][google.spanner.v1.TypeCode] can be mapped to
different SQL types depending on the SQL dialect.
type_annotation][google.spanner.v1.Type.type_annotation]
typically is not needed to process the content of a value
(it doesn't affect serialization) and clients can ignore it
on the read path.
