public static final class FlightSql.CommandGetImportedKeys extends com.google.protobuf.GeneratedMessageV3 implements FlightSql.CommandGetImportedKeysOrBuilder

 Represents a request to retrieve the foreign keys of a table on a Flight SQL enabled backend.
 Used in the command member of FlightDescriptor for the following RPC calls:
  - GetSchema: return the Arrow schema of the query.
  - GetFlightInfo: execute the catalog metadata request.

 The returned Arrow schema will be:
 <
  pk_catalog_name: utf8,
  pk_db_schema_name: utf8,
  pk_table_name: utf8 not null,
  pk_column_name: utf8 not null,
  fk_catalog_name: utf8,
  fk_db_schema_name: utf8,
  fk_table_name: utf8 not null,
  fk_column_name: utf8 not null,
  key_sequence: int32 not null,
  fk_key_name: utf8,
  pk_key_name: utf8,
  update_rule: uint8 not null,
  delete_rule: uint8 not null
 >
 The returned data should be ordered by pk_catalog_name, pk_db_schema_name, pk_table_name, pk_key_name, then key_sequence.
 update_rule and delete_rule returns a byte that is equivalent to actions:
    - 0 = CASCADE
    - 1 = RESTRICT
    - 2 = SET NULL
    - 3 = NO ACTION
    - 4 = SET DEFAULT
