Class TypeAnnotationCode (3.19.0)

TypeAnnotationCode(value)

TypeAnnotationCode is used as a part of Type][google.spanner.v1.Type] to disambiguate SQL types that should be used for a given Cloud Spanner value. Disambiguation is needed because the same Cloud Spanner type can be mapped to different SQL types depending on SQL dialect. TypeAnnotationCode doesn't affect the way value is serialized.
