Re: Multiple addJoin with OR
Hi Ludwig, never done that, but I would suppose you could use criteria.getNewCriterion and use the SqlEnum.JOIN as your comparison. Than use criteria.criterion.or to create an or between the two. See: http://db.apache.org/torque/releases/torque-3.3/runtime/apidocs/org/apache/torque/util/Criteria.html http://db.apache.org/torque/releases/torque-3.3/runtime/apidocs/org/apache/torque/util/SqlEnum.html http://db.apache.org/torque/releases/torque-3.3/runtime/apidocs/org/apache/torque/util/Criteria.Criterion.html Regards, Hidde. - Ludwig Magnusson lud...@itcatapult.com wrote: Hi!

Re: Antwort: Correct way to getRelatedObjects with each relatedObject reference to this object?
Hi Thomas,
as an user / programmer I would expect parent.getChildren().getParent() to
return the original parent object. Thus I would agree that it feels natural to
set the parent of the children upon retrieval of those children.
Regards,
Hidde.

I would believe that the behaviour you describe would make sense
generally. Any opinions on that from other people ? By doing this one
would increase coupling between objects.

Re: SQL TIMESTAMP and Torque java.util.Date mapping.
Hi, criteria.add(TestPeer.EXPIRES, (Object) null, Criteria.ISNULL) doesn't work? Regards, Shinkan wrote: Hi again there ! I have a TIMESTAMP type column in a schema, and the Torque maps it to java.util.Date, which is really convenient most of the time. BUT, I would like to check for this column nullity, SQL point-of-view. That's to say, I have to check that this field, let's call it expires, is NULL Timestamp (00-00- 00:00:00). Trying to compare expires against new Date(0) fails as new Date(0) gives (and that's obvious), the first UNIX timestamp date. I can use New Date(int, int, int, int, int, int) BUT it is deprecated, and I really would like to avoid this. So, how can I build a Criteria to check if my field expires from table test is NULL timestamp (00-00- 00:00:00) ? timeCrit.add( TestPeer.EXPIRES, ?); Thanks in advance ! -- Hidde Boonstra Us Media B.V.

Re: Log4J + Torque ... gonna drive me mad.
Hi Shinkan, I'm glad to hear you fixed it :-) An application should not output warnings if there is nothing to worry about, I agree. Are you 100% sure that Log4J is configured before anything else happens? I've seen those kind of messages, but mostly because things where being configured / started, or used before Log4J was up and running... B.t.w. if you want to be sure nothing is written to the standard out or err, you can redirect the outputs using System.setErr and System.setOut. This might be a smart thing to do if your running as a deamon? Kind regards, Shinkan wrote: As you say, this don't prevent Log4J from working. But these 2 lines are really annoying as my app is a server app, which is run in background as a daemon on Linux. Thus, they are outputed from System.err, and I can't guarantee that production tasks in production env which will use this server will not require stop on standard error output.

Re: Plural Tables Names
Hi Graham, you can specify the java name of your table in the schema xml. You can specify it using the javaName attribute on the table element.

Re: idbroker generates existing ID's
Thanks Adam Alvaro, I use a normal size integer, so I should be save for a while. The case of the table name is a good issue. I have been struggling with MySQL and the id_table for a while. I have checked both databases, but alas, no double id tables. I think I'll fall back to Torque 3.2 for now and see if the problems reoccur. I might be 'blaming' Torque while the problems might be related to some other package:-) Thanks for your input, and I'll keep the list informed if I find anything relevant...

idbroker generates existing ID's
Hi all, we're experiencing some weird trouble while using the IDBroker. Two of our sites (one running on MySQL 5.x + Torque 3.3-RC1 and one running on Postgres 8.x + Torque 3.3-RC2) start throwing duplicate key exceptions after running (without problems) for a while. The IDs generated are much lower than the next_id entry in the id_table. When I restart the application the problem is gone, but after a while (days/weeks) it returns. Does anybody know what is going on, or has experienced similar problems? Thanks in advanced, with kind regards, -- Hidde Boonstra Us Media B.V.

Re: Torque is very slow to do a .copy of an object :( Why?
Hi Alain, does your object have many relations (foreign key constraints)? I just looked into the copy method and I see it does a deep copy, so if you have many relations, or many related entries in your database, these will all be copied into your copy. This might explain why it gets slower when there is more data... Greetz, Hidde. philipina wrote: Hello, I'm using torque to connect to my Mysql database.

Re: Torque is very slow to do a .copy of an object :( Why?
Hi, sorry, but I think that's what I mean:-) So if you have object1 and object2 which references to object1 and you do a copy on object1 it will also copy and add all object2 instances that refer to object1. It looks like this is recursive, because objects that refer to object2 will probably be copied as well... Hope this helps to explain your slowdown, Hidde. philipina wrote: Hi, One other object has a reference to the object I want to copy but the object I want to copy has no reference (foreign key) to any other object.

torque-maven-plugin 3.3-RC1: 'subpackageManager' property - TorqueException
Hi all, I'm using the Maven2 torque plugin to generate my object model. When using the 'subpackageManager' configuration property the generated classes end up in the specified package. However, the field 'DEFAULT_MANAGER_CLASS' in my Base...Manager is missing the specified subpackage. This results in a TorqueException caused by a ClassNotFoundException. I have looked for another property but couldn't find any. Can anybody tell me if I'm missing something, or if this is perhaps a feature of the current version of the generator plugin? Thanks, -- Hidde Boonstra Us Media B.V.

Re: torque-maven-plugin 3.3-RC1: 'subpackageManager' property - TorqueException
Ok, my bad.
It says:
protected static final String DEFAULT_MANAGER_CLASS
= ${packageManager}.${interfaceName}Manager;
in the head, in stead of
protected static final String DEFAULT_MANAGER_CLASS
= ${package}.${interfaceName}Manager;
as in mine.
I've already created the issue (TORQUE-81), so feel free to close it as
invalid / duplicate:)
Thanks greets,
Hidde.
