Subject [jira] [Commented] (DERBY-6527) Fix errors in foreign keys documentation
Date Sat, 10 May 2014 21:56:53 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993717#comment-13993717

Kim Haase commented on DERBY-6527:
----------------------------------

Oops, I think I see what you mean. You are talking about a delete analogue to the following
statement about the update rule:

"When a value in a column of the dependent table is updated, and that value is part of a foreign
key, NO ACTION is the implicit update rule."

So I gather it is correct to say exactly the same thing for delete --

"When a value in a column of the dependent table is deleted, and that value is part of a foreign
key, NO ACTION is the implicit delete rule."
