      Description

      When a generated column is present in a table, an INSERT DISTINCT fail:
      Repro:

      create table t(i integer,
      j integer not null generated always as (i*66));
      insert into t values 1,2;
      insert into t select distinct i from t;

      In an insane build we see this assertFailure:

      ij version 10.5
      ij> connect 'jdbc:derby:wombat2;create=true';
      ij> create table t(i integer,
      j integer not null generated always as (i*66));
      0 rows inserted/updated/deleted
      ij> insert into t values 1,2;
      2 rows inserted/updated/deleted
      ij> insert into t select distinct i from t;
