Hi Sergey,
now I get your point, you are right this is a bug.
Your attached patch was removed by the apache-server (I don't get it),
please open an issue in jira
http://issues.apache.org/jira/browse/OJB
and add your patch. I will integrate it ASAP.
Thanks much!
regards,
Armin

Hi Armin,
I am using OJB 1.0.3 and only used "link", didn't try "object". I made a
quick fix in MtoNBroker, that looks like it works for me now, please see
the attached file. And find it under "FIXED" comment,
The example I gave is simplified from the real. But I think it gives the
idea where problem is-> OJB assumes that (M to N) table has only
different fields for M key and N key when actually in my case both keys
are composite and some fields are common.
M key: k1,m1
N key: k1,n1
So (M to N) table has only 3 keys: k1,m1,n1
, not 4: k1,m1,k1,n1.
If you still need a full descriptor let me know, and I will send it to
you...
Regards,
Sergey

Hi Sergey,
which version of OJB do you use?
Could you post the whole class-descriptor for MyClass and the m-side
class.
Is the wrong sql-statement only be generated with auto-update="link" or
for "object" too?

Armin

Folks,
When I have :
<class-descriptor class="com.lear.app.sqs.beans.MyClass">
...
<collection-descriptor name="allUsers"
collection-class="org.apache.ojb.broker.util.collections.ManageableArray
List"
element-class-ref="com.lear.app.sqs.beans.MyUser"
auto-update="link"
indirection-table="CLASS">
<fk-pointing-to-this-class column="SPUNIT" />
<fk-pointing-to-this-class column="SPCLASS" />
<fk-pointing-to-element-class column="SPUNIT"
/>
<fk-pointing-to-element-class column="SPUSER"
/>
</collection-descriptor>
</class-descriptor>
And then call create(myClass) on Persistent Broker, when storing link
for a collection it generates INSERT SQL with duplicated field SPUNIT
->
results in SQL exception:
[org.apache.ojb.broker.accesslayer.StatementsForClassImpl] ERROR:
[SQL0121] Duplicate name SPUNIT not allowed.
INSERT INTO CLASS (SPUNIT, SPCLASS, SPUNIT,SPUSER) VALUES (?,?,?,?)
Any workaround ideas?
Thank you,
Sergey
