Dag H. Wanvik updated DERBY-4451:
---------------------------------
Attachment: derby-4451c.stat
derby-4451c.diff
Uploading derby-4451c, which fixes the case seen by Knut. It also now handles
INTERSECT/EXCEPT and any nested use of DEFAULT, i.e. use of DEFAULT is only
allowed in a top level table constructor. Note that this does not solve
DERBY-4426, which does not have an explicit target column list, and so is not
checked by forbidGenerationOverrides#forbidGenerationOverrides. We do need to
add this logic here, though, for otherwise we would lose the information that
the user provided a default in a nested table constructor (it would be pruned
away). The alternative would be to just throw
LANG_CANT_OVERRIDE_GENERATION_CLAUSE, but that could be confusing for the
following query:
insert into t(a,b) values (3,default) union all values (3,default)
Added more test cases, rerunning regressions.
> ArrayIndexOutOfBoundsException or ASSERT FAILED when inserting generated
> columns out of order

> Components: SQL
> Affects Versions: 10.5.3.0, 10.6.0.0
> Reporter: Knut Anders Hatlen

> I see this error when I specify the columns in a different order than in the
> table definition. It only fails if a multi-row table constructor is used.
> ij> create table t(a int, b generated always as (-a));
> 0 rows inserted/updated/deleted
> ij> insert into t(b,a) values (default,1);
> 1 row inserted/updated/deleted
> ij> insert into t(b,a) values (default,1), (default, 2);
> ERROR XJ001: Java exception: '1 >= 1:
> java.lang.ArrayIndexOutOfBoundsException'.
> And in a sane build:
> ij> insert into t(b,a) values (default,1),(default,2);
> ERROR XJ001: Java exception: 'ASSERT FAILED More columns in result column
> list than in base table: org.apache.derby.shared.common.sanity.AssertFailure'.
> This bug may be similar to DERBY-4448, but the stack trace is different, and
> DERBY-4448 does not raise an ASSERT FAILED in sane builds.
