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.
