Module fdb_rl_proto::fdb_rl::key_expression::v1::field::field_null_interpretation

Nested message and enum types in FieldNullInterpretation.

Structs

• Distinct
  Missing value (NULL) are allowed multiple times in unique index (PostgreSQL NULLS DISTINCT, Java RecordLayer NOT_UNIQUE). This is the default for PostgreSQL and Java RecordLayer.
• NotDistinct
  Missing value (NULL) cannot be repeated in a unique index. This is very restrictive as a column can have only one NULL value. (PostgreSQL NULLS NOT DISTINCT, Java RecordLayer UNIQUE).
• NotNull
  Field is not NULL. As mentioned in the above table, in proto3 this is only possible for a singular numeric, enum, bytes, string, bool type.

Enums
