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.
