Subject [jira] [Commented] (DERBY-6605) "Derby support for SQL-92 features" topic in Reference Manual needs updating
Date Thu, 12 Jun 2014 10:29:02 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14029004#comment-14029004
] 

Knut Anders Hatlen commented on DERBY-6605:
-------------------------------------------

The entry for ALTER domain says "nNo".

I believe the entry for CASE expression can say "Yes" now with the extra bits we've put into
10.11.

"predicates: OVERLAPS" says "Yes, with Java methods". I guess that actually means "No". Derby
does not support the OVERLAPS predicate. Same with "datetime math", but there are supported
JDBC escape functions for doing datetime arithmetics that we could point to.

> The topic "Derby support for SQL-92 features" in the Reference Manual (http://db.apache.org/derby/docs/10.10/ref/rrefsql9241891.html)
seems not to have been substantively updated since about 2007.
> For one thing, the parenthesis "(non-deferrable)" needs to be removed from Table 8 (constraint
support). Also, I think we've supported natural joins for some time. 
> Could someone more knowledgeable than I am go through the items marked "No" and see if
any more need updating? I think those two might be the only ones, but I am not quite sure.
