Mike Matrigali updated DERBY-3963:
----------------------------------
Component/s: SQL
> Referential action ON DELETE SET DEFAULT does not work correctly
> ----------------------------------------------------------------
>
> Key: DERBY-3963
> URL: https://issues.apache.org/jira/browse/DERBY-3963
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Reporter: Dag H. Wanvik
> Attachments: SetDefaultOnDeleteError.java
>
>
> The ON DELETE SET DEFAULT action is not documented (cf. DERBY-3962), but
> Derby accepts the construct.
> Example from JUnit repro SetDefaultOnDeleteError.java:
> > create table dhw( a int default 2, constraint y foreign key(a) references
> > referencedTable(a) on delete set default)
> However, it does not work as expected. It would seem that when the referenced
> table's row is deleted,
> the constraint is checked with the old value of the referencing table (DHW.A)
> instead of the value
> after updating the column with the default as required. After updating to the
> default value the new value should
> be checked again against the referenced table, and if there is a row
> corresponding to the default value, the
> operation should succeed. Derby fails with error:
> ERROR 23503: DELETE on table 'REFERENCEDTABLE' caused a violation of foreign
> key constraint 'YYY' for key (1). The statement has been rolled back
> Stacktrace:
> 1)
> test_1(org.apache.derbyTesting.functionTests.tests.lang.SetDefaultOnDeleteError)java.sql.SQLIntegrityConstraintViolationException:
> DELETE on table 'REFERENCEDTABLE' caused a violation of foreign key
> constraint 'YYY' for key (1). The statement has been rolled back.
