Re: how does one use JDO to run ALTER TABLE sql command?
JDO API doesn't allow schema updating. If you want to make it, you had to use a direct SQL command. -- bye, Luca Garulli www.OrienTechnologies.com On Sun, 19 Sep 2004 18:09:09 -0700 (PDT), Paul Joseph <[EMAIL PROTECTED]> wrote: > hmm...interesting...Thank you for your reply. > > We use JDO a lot in the application but we need the > ability to alter tables alsoit would have been > nice if JDO could have done it! > > thx > Paul > > > > > --- Joerg Heinicke <[EMAIL PROTECTED]> wrote: > > > On 19.09.2004 04:30, Paul Joseph wrote: > > > > > My colleague and I are trying to use jdo to do an > > > "alter table" command. > > > > JDO is an O2R mapper, not a SQL replacement.

Thank you for your reply. I was not able to find an active non-proprietary JDO list. If you know of any, I would be grateful if you could let me know. thx Paul --- Tony Collen <[EMAIL PROTECTED]> wrote: > Paul Joseph wrote: > > Hi, > > > > My colleague and I are trying to use jdo to do an > > "alter table" command. > > > > There don't seem to be any examples showing how > this > > is done and we are having a bit of a tough time. > > > > This isn't the list for it.

hmm...interesting...Thank you for your reply. We use JDO a lot in the application but we need the ability to alter tables alsoit would have been nice if JDO could have done it! thx Paul --- Joerg Heinicke <[EMAIL PROTECTED]> wrote: > On 19.09.2004 04:30, Paul Joseph wrote: > > > My colleague and I are trying to use jdo to do an > > "alter table" command. > > JDO is an O2R mapper, not a SQL replacement.

I would not wonder if it does not work at all. From the error message I guess the query is not pre-tested, but as it does not return a resultset, it fails. There might be a super-duper JDO implementation, that can change the mappings dynamically (as it is needed in your case), but I don't think the reference implementation will do it.

This isn't the list for it. Best to ask on the JDO lists. Regards, Tony - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
