Subject [jira] Commented: (DERBY-3959) Reference Manual needs information on generated columns
Date Wed, 07 Jan 2009 21:48:46 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12661723#action_12661723

Rick Hillegas commented on DERBY-3959:
--------------------------------------

Thanks for the patch, Kim. Looks good. Some comments follow:

Two typos:

rrefsqlj81859
  "Column definition" section: "if" should be capitalized.

rrefsqlj30540
  1st paragraph: "if" should be capitalized.

Substantive issue:

Both rrefsqlj30540 and rrefsqljrevoke say that a table will be dropped if one of its generation
clauses depends on a role-based EXECUTE privilege which is subsquently dropped. The functional
spec says that this is the expected behavior but subsequent discussion on DERBY-481 has failed
to find good motivation for this harsh behavior and, in fact, this is not how Derby behaves
right now. A little more discussion may happen related to this issue on DERBY-3949. However,
I suspect that I will end up removing this harsh assertion from the functional spec and we
should therefore remove this from the user documentation too.

Thanks,
-Rick
