Subject Re: [jira] Created: (DERBY-179) Hibernate bad support
Date Thu, 24 Mar 2005 17:10:17 GMT
Derby doesn't have a built-in rownumber() function -- built-in functions 
are summarized at 
http://incubator.apache.org/derby/manuals/reference/sqlj57.html 
(Reference Manual -> SQL Language Reference -> Built-In Functions).

So, unless the rownumber() function is provided by the user, this 
statement will get a syntax error:

     select * from ( select rownumber() over(order by auctionite0_.ends 
desc) as rownumber_, ...

Also the "over(order by auctionite0_.ends desc)" syntax isn't supported 
by Derby. Derby doesn't have a built-in rownumber() function -- built-in 
functions are summarized at 
http://incubator.apache.org/derby/manuals/reference/sqlj57.html 
(Reference Manual -> SQL Language Reference -> Built-In Functions).

Unless the rownumber() function is provided by the user, this statement 
will get a syntax error:

     select * from ( select rownumber() over(order by auctionite0_.ends 
desc) as rownumber_, ...

Also the "over(order by auctionite0_.ends desc)" syntax isn't supported 
by Derby.

Has anyone else encountered trouble running the Hibernate examples? 
Other list traffic cites success with hibernate -- see 
http://article.gmane.org/gmane.comp.apache.db.derby.user/1000 -- so it 
might be helpful for us to build a list of the examples that work and 
the ones that don't.

If hibernate/derby users will post specifics about what does and doesn't 
work, I'll volunteer to organize that info and put it on the derby web site.
