Class TypeAnnotationCode (3.46.0) 

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.

Enum 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.
PG_OID (4):
    PostgreSQL compatible OID type. This
    annotation can be used by a client interacting
    with PostgreSQL-enabled Spanner database to
    specify that a value should be treated using the
    semantics of the OID type.
