> Cannot insert row when a generated column references an identity column
> -----------------------------------------------------------------------
>
> Key: DERBY-4146
> URL: https://issues.apache.org/jira/browse/DERBY-4146
> Project: Derby
> Issue Type: Bug
> Affects Versions: 10.5.1.0
> Reporter: Knut Anders Hatlen
>
> ij> create table t (c1 int generated always as identity, c2 generated always
> as (c1));
> 0 rows inserted/updated/deleted
> ij> insert into t values (default, default);
> ERROR 23502: Column 'C2' cannot accept a NULL value.
> Preferably, this should work. Alternatively, if it is not supposed to work,
> it should fail when the table is created and the error message should state
> that a generated column is not allowed to reference an identity column.
