Worse than that, the example provided gives you the certainty of never getting a unique identifier. :-D To be precise, undoubtedly you're right :):) Darek

Subject: Trouble with oracle 10g selectKey
Wow, seems I'm dumb-minded today, can not make selectKey work
Following the SQL-Maps-2.pdf I have:
select services_seq.nextval as service_id from dual
insert into Services ( service_id,service_name)
values ( #service_id#,#service_name#)
and dao (I'm using spring) looks like
public class ObjectDao extends SqlMapClientDaoSupport
public int insertObject(Object object) throws DataAccessException
{
//Service service = (Service) object;
//if (service.getService_id() == 0)
//{
//service.setService_id(((Integer) //
//
getSqlMapClientTemplate().queryForObject("getServiceSeq",0)).intValue());
//}
return getSqlMapClientTemplate().update("insert" +
object.getClass().getSimpleName(),object);
}
It tries to insert '0' for service_id. However all works fine if I
uncomment those commented lines where I select sequence manually and
omit the selectKey from sql-map
Can someone indicate any direction where I should look?

Re: daoManager start/end/commit transaction problem - solved:)
Thanks for your answer,I solved the problem
It is difficult to say, but It was very
obvious fault:)
By the way I have one dao
manager.
Problem was that, I had my code different,
than I wrote in my post.
I didn't excecute endTransaction() (It was in
my catch exception section instead of finally section), so after
commitTransaction, transaction was still in progress.
I was tricked by the fact, that commit
transaction should release all resources and locks. Database transaction was
commited, but still locked the tables
Can you explain that magic. I always thought,
that commit releases resources?
Anyway thanks for help
Best regards

transaction problem
Three things:1) You should only have one DAO
manager, even with multiple databases.2) In my opinion, your
transactions should be at the service level. Make more coarse grained
service methods that demarcate transactional scope. 3) Be very
careful with multiple start/commit/end blocks. You should consider a
global transaction manager if you're working with multiple
databases.Cheers,Clinton

Re: Stored procedure with queryForList skipresults and maxresults
I wonder if it is possible to use skip/max in sql statement. Every database has it's own solution for limiting rows: - sql server has top - postgresql : limit and offset - mysql: also limit and offset ( if I have a good memory:) - oracle prior to 9i combination of: rownum, order like this: select * from (select kol1, kol2 from table order by kol1) where rownum <15 - oracle 9i provides analytic function like rownumber and so on and on ...

Re: synchronization between DB and ibatis sqlmaps
Because of laziness:) Writting test cases takes some time. I'm developing application using Tomcat, and I start to realize, that testing on real application takes to much time, including deploying, logging on, and so on. At the beginning it seemed to be a good choice, but it isn't. I have the problem with refreshing sqlmap files by tomcat (it was mentioned on this group, but doesn't work for me), so I have to deploy and reload application. Even using ant to reloadTask and than logon is a little slow. So test case seems to be the fastest way. What is your advice. Is building test cases the best practise and fastest of doing this?

Re: I must restart Tomcat when I modify some SQL Map XML files in SQLMapConfig.xml
Can't you just use manager included in Tomcat, you can reach it at /manager/html/list and then just reload application ? I do that:) Darek - Original Message - From: Zarar Siddiqi To: user-java@ibatis.apache.org ; Sylvain Pelletier Sent: Monday, July 11, 2005 7:20 PM Subject: Re: I must restart Tomcat when I modify some SQL Map XML files in SQLMapConfig.xml Instead of restarting Tomcat, perhaps you should setup your application so that you just have to reload/redeploy the context for the startup listeners to kick in. Restarting tomcat can be slow while reploying works like a breeze. I'm using Intellij and you can run Tomcat within it. I'm sure Eclipse has the same feature.

I'm using sqlmap without using the dao manager of ibastis. I work under myeclipse and when I modify the content of SQL MAP xml files (to add a select statement for example), the changes are not do in real-time. I'm actually restarting tomcat each times I changes SQL MAP xml files and it's a quite boring !! Thanks Sylvain
Re: Best mechanism to read large datasets
Title: Best mechanism to read large datasets Can you explain or anyone else, how it works or what is the best practise? I think that statement is open, and for each row method public void handleRow (Object object); is invoked or something like that I assume, that we want to process a large datasets, and do some operations. Should't be better in that case to use stored procedure, and use i.e cursor in database to handle this, if we have such opportunity? It seems to be much faster, then using JDBC. We are working on large datasets. I don't have time for excercise now, but for 500 000 records to process, using only stored procedure, should be much faster. What are your opinions?

Is there a way for ibatis to read each row from table and discard it as soon as it is processed, so I don't run into out of memory issues?
Re: Best mechanism to read large datasets
Title: Best mechanism to read large datasets Can't you divide your result into pages with smaller number of records ? queryForList with proper parameters should do that.

Avoiding N+1 selects
Hi According to the documentation it is possible to ommit N+1 selects using i.e: What if category has several attributes, I wouldn't like to recopy them to other resultMap. Adding new attributes, requires to place it in two or more resultMaps. I would like just to reuse categoryMap from somewhere else. Something like this on page 28 (resultMap): But according to the documentation calendarQuarter is expected to have get and set methods for months, as a List, I would like to have only one month of class calendarMonth Example mentioned above, throws exception: ClastCastException, I suppose it expects months to be List, but I would like it to be one CalendarMap Is it possible, to point down, that I want only one Bean, not the List?
