Hi, I have a database table with PK as a 'identity' (SQL2000Server),
and I'm using hbm2hbmxml to generate my *.hbm.xml files.
My question is the hbm.xml genrated have:



What I want is <generator class="identity" />

can I make hbm2hbmxml do this? Or I have to manually change the hbm.xml file?

Thanks!

that is controllable via a reveng.xml

please not that hbm2hbmxml has nothing to do with the reverse engineering - it is the jdbcconfiguration that does this.

But when my application tried to insert a record into DB, the A.hbm.xml will instruct Hibernate how to do the insertion, right?

In my table A, I have a PK A_ID as is a 'identity' PK, which means the PK should be generated by DB, not specified by the application.

So if in my A.hbm.xml, I have
<id name="fileId" type="long">
<column name="A_ID" />
<generator class="assigned"/>
</id>

Hibernate will complain about that I'm trying to insert a PK with a explicit value.
what I want is that make hbm2hbmxml to generate A.hbm.xml as:

<id name="fileId" type="long">
<column name="A_ID" />
<generator class="identity"/>
</id>
So Hibernate will not complain when I insert.

Please advice, thanks!

Quoting Max.


hbm2hbmxml does not do the reverse engineering of the database.

David:
Thank you for your reply, but I'm not trying to do reverse engineering here, am I?
I'm trying to insert data using Hibernate, and A.hbm.xml is guiding the insertion, right? but my A.hbm.xml is not instructing the insertion correctly because the 'identity' problem. I can manually change my A.hbm.xml, and it works. My question is, I want the A.hbm.xml to be generated correctly, so I do not have to manually change it after it is generated, is there a way to do this? Or I have to fix my A.hbm.xml manually?

Thanks,

you are talking about "generating hbm.xml" that definitly sounds like you are doing some kind of reverse engineering....
