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.

Values: TYPE_ANNOTATION_CODE_UNSPECIFIED (0): Not specified. PG_NUMERIC (2): PostgreSQL compatible NUMERIC type. This annotation needs to be applied to Type][google.spanner.v1.Type] instances having NUMERIC][google.spanner.v1.TypeCode.NUMERIC] type code to specify that values of this type should be treated as PostgreSQL NUMERIC values. Currently this annotation is always needed for NUMERIC][google.spanner.v1.TypeCode.NUMERIC] when a client interacts with PostgreSQL-enabled Spanner databases. PG_JSONB (3): PostgreSQL compatible JSONB type. This annotation needs to be applied to Type][google.spanner.v1.Type] instances having JSON][google.spanner.v1.TypeCode.JSON] type code to specify that values of this type should be treated as PostgreSQL JSONB values. Currently this annotation is always needed for JSON][google.spanner.v1.TypeCode.JSON] when a client interacts with PostgreSQL-enabled Spanner databases.
