> 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(i) values 1,2;
> insert into t(i) 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
