Subject [jira] Commented: (DERBY-5121) Data corruption when executing an UPDATE trigger
Date Tue, 15 Mar 2011 17:55:29 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13007049#comment-13007049
] 

Mamta A. Satoor commented on DERBY-5121:
----------------------------------------

Rick, this data corruption should only occur with row level triggers which are using columns
in trigger action through REFERENCING clause. All the other kinds of triggers including statement
level triggers should not be impacted.

I will soon submit a patch for review which will have the test cases provided by you in triggeredBug2.sql.
