Subject [jira] Commented: (OPENJPA-1132) Dropping constraints fails on MySQL
Date Thu, 11 Jun 2009 02:51:07 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12718284#action_12718284
] 

Michael Dick commented on OPENJPA-1132:
---------------------------------------

Looks like ALTER TABLE xxx DROP FOREIGN KEY yyy should work [1]. I'm not sure if there's a
more general name we can use  though.
