Dag H. Wanvik created DERBY-6576:
------------------------------------
Summary: A immediate Fk constraint blows up iff its referenced PK
is deferred and we modify a duplicate key column
Key: DERBY-6576
URL: https://issues.apache.org/jira/browse/DERBY-6576
Project: Derby
Issue Type: Bug
Components: SQL
Reporter: Dag H. Wanvik
Similar to the issue in DERBY-6559, except here we modify the key in the
referenced table. This leads Derby to check for any referencing FK and throw,
even if there are other (formerly) duplicate rows that satisfy the FK
constraint.
