Subject [jira] [Created] (DERBY-6576) A immediate Fk constraint blows up iff its referenced PK is deferred and we modify a duplicate key column
Date Tue, 13 May 2014 18:56:14 GMT
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.
