[ http://issues.apache.org/jira/browse/DERBY-1057?page=comments#action_12427584 ] Laura Stewart commented on DERBY-1057: --------------------------------------
Mamta - I have re-written the text about PUBLIC and user-level privileges re: views, triggers, and contstrants. Below is the updated text. Please review and let me know if I have the correctly documented now :-) Exception: When you create a view, trigger, or constraint, Derby first checks to determine if you have the required privileges at the user-level. If you have the user-level privileges, the object is created and is dependent on that user-level privilege. If you do not have the required privileges at the user-level, Derby checks to determine if you have the required privileges at the PUBLIC level. If you have the PUBLIC level privileges, the object is created and is dependent on that PUBLIC level privilege. After the object is created, if the privilege on which the object depends on is revoked, the object is automatically dropped. Derby does not try to determine if you have other privileges that can replace the privileges that are being revoked. Example 1 User zhi creates table t1 and grants SELECT privileges to user harry on table t1. User zhi grants SELECT privileges to PUBLIC on table t1. User harry creates view v1 with the statement SELECT * from zhi.t1. The view depends on the user-level privilege that user harry has on t1. Subsequently, user zhi revokes SELECT privileges from user harry on table t1. As a result, the view harry.v1 is dropped. Example 2 User anita creates table t1 and grants SELECT privileges to PUBLIC. User harry creates view v1 with the statement SELECT * from anita.t1. The view depends on the PUBLIC level privilege that user harry has on t1 since user harry does not have user-level privileges on table t1. Subsequently, user anita revokes SELECT privileges from PUBLIC on table t1. As a result, the view harry.v1 is dropped. > documentation to address Grant/Revoke (Derby-464) > ------------------------------------------------- > > Key: DERBY-1057 > URL: http://issues.apache.org/jira/browse/DERBY-1057 > Project: Derby > Issue Type: Sub-task > Components: Documentation > Affects Versions: 10.0.2.0 > Reporter: Eric Radzinski > Assigned To: Laura Stewart > Fix For: 10.2.0.0 > > Attachments: derby1057_devguide.diff, derby1057_devguide3.diff, > derby1057_devguide_html.zip, derby1057_devguide_html3.zip, > derby1057_ref.diff, derby1057_ref3.diff, derby1057_ref_html.zip, > derby1057_tuning3.diff, derby1057_tuning4.diff, derby1057_tuning_html.zip, > derby1058_ref_html3.zip, devguide_html2.zip, ref_html2.zip, > rtunpropersqlauth.html > > -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
