----------------------------------------------------------------
Wondering if perhaps it is {{CreateIndexConstantAction}} for the deferred
primary key that is responsible for associating the {{ConstraintDescriptor}}
with the corresponding UUID? If so it does not appear to be doing so - the
braindump patch removes
{code}
if (initiallyDeferred) {
DeferredConstraintsMemory.associateDuplicatesWithConglomerate(
lcc, conglomId);
}
{code}
but does not add a replacement based on UUIDs, AFAICT...

> Key: DERBY-6665
> URL: https://issues.apache.org/jira/browse/DERBY-6665
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.11.0.0
> Reporter: Knut Anders Hatlen
> Attachments: braindump.diff, junit.diff
>
>
> See the following script:
> {noformat}
> ij version 10.11
> ij> connect 'jdbc:derby:memory:db;create=true';
> ij> create table t1(x int primary key);
> 0 rows inserted/updated/deleted
> ij> create table t2(x int primary key);
> 0 rows inserted/updated/deleted
> ij> create table t3(x int, constraint fk1 foreign key (x) references t1
> initially deferred, constraint fk2 foreign key (x) references t2 initially
> deferred);
> 0 rows inserted/updated/deleted
> ij> insert into t1 values 1;
> 1 row inserted/updated/deleted
> ij> autocommit off;
> ij> insert into t3 values 1;
> 1 row inserted/updated/deleted
> ij> insert into t2 values 1;
> 1 row inserted/updated/deleted
> ij> delete from t1;
> 1 row inserted/updated/deleted
> ij> commit;
> ij> select * from t1;
> X
> -----------
> 0 rows selected
> ij> select * from t2;
> X
> -----------
> 1
> 1 row selected
> ij> select * from t3;
> X
> -----------
> 1
> 1 row selected
> {noformat}
> Since T3.X contains a value (1) that is not present in T1, the foreign key
> FK1 is violated, and the COMMIT statement should have failed.
