[ http://issues.apache.org/jira/browse/DERBY-1686?page=comments#action_12431095 ] Yip Ng commented on DERBY-1686: -------------------------------
Hmm... I probably should not make any assumptions for the equals method since it could changed in the future and not rely on the compilation schema. I'll remove the dba check at compilation time and resubmit the patch. Thanks for your comment, Mamta. > Grant/Revoke: Attempt to GRANT access to another user on a VIEW, created by > the current user with only SELECT privilege on the base table does not fail > ------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: DERBY-1686 > URL: http://issues.apache.org/jira/browse/DERBY-1686 > Project: Derby > Issue Type: Bug > Components: SQL > Affects Versions: 10.2.1.0 > Environment: Any > Reporter: Rajesh Kartha > Assigned To: Yip Ng > Fix For: 10.2.1.0 > > Attachments: derby1686-trunk-diff01.txt, derby1686-trunk-diff02.txt, > derby1686-trunk-stat01.txt, derby1686-trunk-stat02.txt, > select_table_no_privilege.sql > > > With authentication on, attempting to execute a GRANT privilege to 'user3' > on a VIEW created by the 'user2' - who has only SELECT privilege > on the base table created by 'user1' does not fail.
