Subject [jira] Created: (DERBY-4146) Cannot insert row when a generated column references an identity column
Date Sun, 05 Apr 2009 20:47:13 GMT
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.
