↳ type_annotation
int
TheTypeAnnotationCodethat 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 singleTypeCodecan be mapped to different SQL types depending on the SQL dialect.type_annotationtypically is not needed to process the content of a value (it doesn't affect serialization) and clients can ignore it on the read path.
↳ proto_type_fqn
string
Ifcode==PROTOorcode==ENUM, thenproto_type_fqnis the fully qualified name of the proto type representing the proto/enum definition.
