Re: Feedback about issue with MySQL and get primary key
Could it be that the NO_Sent_Notification_Request_
Log_TEST is a new table that you have created lately and that your
EO_PK_TABLE could not locate it for primary key. Just curious.

I don't want to bug the list too much because I can deal easily with this

However my curiosity would be happy if someone knows the reason.
That's said, Cheong, I doubt the cause are those you think for 2 reasons:
- informations inserted in raw SQL are not fetched as EO, never (they are
used for statistics in another WO app) and I pass a new fresh EC to
EOUtilities.raw...
- NONotificationRequestLog object is also new, inserted also in a new
EC as showed in the code.
So I can't invalidate any object because one is not known by EOF and the
other one is just created.
I made another test: I put the raw insert command in the same method as
below using only one EC and I get the same issue: exception when EOF tries
to get a primary key. So I'm pretty sure that the insert command causes the
exception when I call saveChanges

Hi Philippe
I think somehow 'NO_Sent_Notification_Request_Log_TEST' is already
registered as an existing object in your ec. This caused the ec to fetch
the object again and therefore failed and aborted. I may be just reiterated
your point to be sure : )
Just to test, you may need to invalidate all objects in the ec and try to
save the log object again.

Hi Ray,
Thank you for the tip. That's something interesting to change the sql
expression on the fly. I was looking for that too.
But you don't get me so I gonna try to be explain with more concise
explanations.
The algorithm is the following:
1 - get data from the DA, check data and return a result (basically 2
results : data accepted or not)
2 - if result = data_accepted, I insert new data using raw sql
3 - write into a log entity (in any circumstances) using EOF aka create an
object and insert it into an ec.
What I tried to explain is that when the EOUtilities.rawRowsForSQL is
executed in step 2 (and it works, I don't have any issue here), the step 3
fails because he can't get a primary key. If the step 2 is not executed, the
step 3 is executed successfully.
I put the simple code below that is executed, just in case but nothing
weird I guess (I removed the try/catch).
Cheers,
Philippe

I recall that being a bug in earlier 5.4 versions, is it not fixed in 5.4.3? Are you using Wonder? I think that was fixed somewhere. If you go to the website http://www.mydomain.com and click around the non-secure area, it will show the URL always as http://www.mydomain.com. As soon as it goes to a secure URL, it displays as https://mydomain.com(without the www in front). Does anyone know where this is generated from? I'd guess from the virtual host in Apache. Possibly with an incorrect DNS record somewhere. It is clearly setting the value from somewhere. Perhaps it has something to do with my adaptor URL? In the JavaMonitor page is says to specify the full URL to the adaptor but I have always just used /app/WebObjects as I use the same adaptor for various apps running on different domains. Would it be related to that? I'd doubt it. I would just like it to come back with https://www.mydomain.com instead as once it changes to the URL with the www, it stays that way.

Hi Stefan
I dare to suggest that it is not due to respnse/request. I think it has
to do with the Windows/Java that the file size it could handle in memory
when using FileInputStream. IIRC I had encountered similar file size
limitation when doing file encryption with size more than 30M some time ago.
Just 2c.

Re: Binary primary keys
Hi
I think it will be easier to do it from Cascade Delete Rule (define at
EOModeler). Such as:
organization -departments - users - projects - projectStatuses...
By deleting organization alone, all objects defined in the CasCade Delete
Rule will just being deleted in single line:
ec.deleteObject(anOrganizaton);
It saves you time to do delete iterations, and this is the beauty of WO
without raw SQL.
Cheers
Cheong Hee
Well the idea is to select a single primary key and then yes it to quickly
delete a large number of records from a table.
Using SQL query like this:
DELETE FROM cms.ms_contestant WHERE contest_id = (SELECT contest_id
FROM cms.ms_contestant WHERE contest_event = '2009 Contest');
Rather then WebObjects code like this:
NSArray contestants = contest.contestants();
for(int i = 0; i contestants.count(); i++){
Contestant contesant = (Contestant)contestants.objectAtIndex(i);
ec.deleteObject(contestant);
}
Well, that seems like the hard way.
How about:
contest.deleteAllContestantRelationships();
That will do basically what you've written above, but it's one line of code
and will properly handle both sides of the relationship.
Or, if the contestant() relationship on Contest either Owns Destination or
has a Cascade delete rule:
ec.deleteObject(contest);
I'm not sure what the SQL will look like for that though.
Are you running into performance problems, or simply anticipating them?
