Reference documentation and code samples for the Cloud Spanner V1 API module Google::Cloud::Spanner::V1::TypeAnnotationCode.
TypeAnnotationCode
is used as a part of 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.
Constants
TYPE_ANNOTATION_CODE_UNSPECIFIED
value: 0
Not specified.
PG_NUMERIC
value: 2
PostgreSQL compatible NUMERIC type. This annotation needs to be applied to
Type instances having
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 when a client interacts with
PostgreSQL-enabled Spanner databases.
PG_JSONB
value: 3
PostgreSQL compatible JSONB type. This annotation needs to be applied to
Type instances having
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
when a client interacts with PostgreSQL-enabled Spanner databases.
PG_OID
value: 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.
