Martin,

Is is possible to set an option to have a single ref table created for
many-to-many relationships. Currently I see two table created for such
relationships, my DB guys would like to see just a single table for each
relationship.

I read on the Elver site that many-to-many relationships have two table
created, also a mention that if an option is set to exclude indexes a
single talble is create...

Thanks,
Mark.

Mark,
Yes Hibernate can't work with indexed many-to-many in a single join table therefore the m-t-m is
split in two o-t-m's.
To set indexed to false for the many-to-many: can you try the following annotation on the
many-to-many ereference: @ManyToMany(indexed=false).

There is a global option to set indexed to false for all one-to-many ereferences but this option is
not implemented for many-to-many. Please enter a bugzilla if this feature is also helpfull for
many-to-many.

Martin,

Thanks. Does this annotation go in the mapping file or the ecore file..?

In the ecore file (or a separate xml), but it is only picked up when you regenerate the mapping file
(or do not use a mapping file).

Martin,

I am trying to place the annotation in my ecore file. But I know zero xml
and can
not make this work...

Do you have the acutal xml block of code, and where it should be located
in the
ecore file for me..?

Thanks again,
Mark.

Mark,
It is easier to open the ecore in the default ecore editor and then right click on the ereference
and choose add child > eannotation.
The source of the eannotation should be teneo.jpa
Then add a details entry in the eannotation (right click on it). The key of the details should be
appinfo (or value) and the Value should then be:
@ManyToMany(indexed=false)

Probably you have to add the same annotation on the other side of the eannotation.

Martin,

Did this. But I see no difference in the mapping file after re-generating.

In the ecore file I find the following:

<eStructuralFeatures xsi:type="ecore:EReference" name="services"
upperBound="-1"
eType="#//Service" eOpposite="#//Service/contacts">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@ManyToMany(indexed=false)"/>
</eAnnotations>
</eStructuralFeatures>


and...

<eStructuralFeatures xsi:type="ecore:EReference" name="contacts"
upperBound="-1"
eType="#//Contact" eOpposite="#//Contact/services">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@ManyToMany(indexed=false)"/>
</eAnnotations>
</eStructuralFeatures>

but the mapping file contains

<list name="services" lazy="true"
cascade="merge,persist,save-update,lock,refresh" table="`contact_service`">
<key update="true">
<column name="`contact_e_id`" not-null="true" unique="false"/>
</key>
<list-index column="`contact_services_idx`"/>
<many-to-many entity-name="Service" unique="false">
<column name="`service_e_id`" not-null="true" unique="false"/>
</many-to-many>
</list>


and ...

<list name="contacts" lazy="true"
cascade="merge,persist,save-update,lock,refresh" table="`service_contact`">
<key update="true">
<column name="`service_e_id`" not-null="true" unique="false"/>
</key>
<list-index column="`service_contacts_idx`"/>
<many-to-many entity-name="Contact" unique="false">
<column name="`contact_e_id`" not-null="true" unique="false"/>
</many-to-many>
</list>



Which looks like two tables will be used as before.

Thanks,
Mark.

Did you regenerate the java source code? This is required after an ecore change (the ecore is not
read from the ecore file but from the runtime generated EPackage class).

Martin,

Yes I did. I re-generated the model code, then right clicked on the ecore
and
created the hibernate mapping file using super-class option.

The annotation is in the effected java source for the modeled classes.

Can you try indexed="false" instead of indexed=false?

If this works then this is a bug...

You can debug into the class DefaultAnnotator and then the method
processBidirectionalManyToManyReference. In the end of this method (after if (joinTable.getName() ==
null) the name of the jointable is set.

With the double quotes around false, the mapping file created is emtpy,

Hmm I have a testcase with this approach which works fine. Okay back to the old way then (without
quotes).
What happens when you debug into the DefaultAnnotator?

Martin,

Debugging results in the annotation working.

In order to debug I used my program which creates the dataStore and then
calls getMappingXML(). The file returned looked correct, and the resulting
database only has a single table.

Generating the mapping file manually by right clicking on the ecore file
did not work, but I will verify.

Mark.

Hmm that's strange, can it be that the generated mapping file was not refreshed (so the change was
not visible)?

There is also a direct method in HbHelper to create the mapping file.

Martin,

I can not verify that the manual method fails to generate the correct
mapping file. It looks fine now. I did however restart Eclipse prior the
test.

I would also let you know that I had a similar problem to the other thread
in this group, [Teneo] Blank hibernate.hbm.xml?, when I first tried the
manual generation method. Later on, certainly after an Eclipse restart the
process worked fine, but the first couple of times I tried the mapping
file was empty. And there was no ecore change.

Mark.

Did this. But I see no difference in the mapping file after re-generating.

In the ecore file I find the following:

<eStructuralFeatures xsi:type="ecore:EReference" name="services"
upperBound="-1"
eType="#//Service" eOpposite="#//Service/contacts">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@ManyToMany(indexed=false)"/>
</eAnnotations>
</eStructuralFeatures>


and...

<eStructuralFeatures xsi:type="ecore:EReference" name="contacts"
upperBound="-1"
eType="#//Contact" eOpposite="#//Contact/services">
<eAnnotations source="teneo.jpa">
<details key="appinfo" value="@ManyToMany(indexed=false)"/>
</eAnnotations>
</eStructuralFeatures>

but the mapping file contains

<list name="services" lazy="true"
cascade="merge,persist,save-update,lock,refresh" table="`contact_service`">
<key update="true">
<column name="`contact_e_id`" not-null="true" unique="false"/>
</key>
<list-index column="`contact_services_idx`"/>
<many-to-many entity-name="Service" unique="false">
<column name="`service_e_id`" not-null="true" unique="false"/>
</many-to-many>
</list>


and ...

<list name="contacts" lazy="true"
cascade="merge,persist,save-update,lock,refresh" table="`service_contact`">
<key update="true">
<column name="`service_e_id`" not-null="true" unique="false"/>
</key>
<list-index column="`service_contacts_idx`"/>
<many-to-many entity-name="Contact" unique="false">
<column name="`contact_e_id`" not-null="true" unique="false"/>
</many-to-many>
</list>



Which looks like two tables will be used as before.

Thanks,
Mark.

Martin,

Yes I did. I re-generated the model code, then right clicked on the ecore
and
created the hibernate mapping file using super-class option.

The annotation is in the effected java source for the modeled classes.

Can you try indexed="false" instead of indexed=false?

If this works then this is a bug...

You can debug into the class DefaultAnnotator and then the method
processBidirectionalManyToManyReference. In the end of this method (after if (joinTable.getName() ==
null) the name of the jointable is set.

Martin,

With the double quotes around false, the mapping file created is emtpy,
except for the header...

Hmm I have a testcase with this approach which works fine. Okay back to the old way then (without
quotes).
What happens when you debug into the DefaultAnnotator?

Martin,

Debugging results in the annotation working.

In order to debug I used my program which creates the dataStore and then
calls getMappingXML(). The file returned looked correct, and the resulting
database only has a single table.

Generating the mapping file manually by right clicking on the ecore file
did not work, but I will verify.

Mark.

Mark,
Hmm that's strange, can it be that the generated mapping file was not refreshed (so the change was
not visible)?

There is also a direct method in HbHelper to create the mapping file.

Martin,

I can not verify that the manual method fails to generate the correct
mapping file. It looks fine now. I did however restart Eclipse prior the
test.

I would also let you know that I had a similar problem to the other thread
in this group, [Teneo] Blank hibernate.hbm.xml?, when I first tried the
manual generation method. Later on, certainly after an Eclipse restart the
process worked fine, but the first couple of times I tried the mapping
file was empty. And there was no ecore change.

Mark.
