public enum TypeAnnotationCode
Reference documentation and code samples for the Google Cloud Spanner v1 API enum TypeAnnotationCode.
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.

Name | Description |
PgJsonb |
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. |
PgNumeric |
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. |
PgOid |
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. |
Unspecified |
Not specified. |
