Reference documentation and code samples for the Cloud Spanner V1 Client class Type.
Type
indicates the type of a Cloud Spanner value, as might be stored in a
table cell or returned from an SQL query.
Generated from protobuf message google.spanner.v1.Type
Namespace
Google \ Cloud \ Spanner \ V1Methods
__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ code
↳ array_element_type
↳ struct_type
↳ type_annotation
int
The 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 can be mapped to different SQL types depending on the SQL dialect. 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.
getCode
Required. The TypeCode for this type.
setCode
Required. The TypeCode for this type.

If code
== ARRAY
, then array_element_type

is the fully
