Hi,

I have several classes in a EMF model and these classes will be mapped
into ONE table . How to write the mapping file to only let one class to
insert/update/delete the table record and the others just mapped to some
fields?

Thanks in advance!


Anthony

Hi Anthony,
I think you mean embedded but to be sure can you give a small example of what you want to achieve?

Martin,

Thank you for help.

I just learn to write my mapping file.

It seems that when a new persistable object was saved
a new record will be inserted into its mapped table.

In my case, the sample structure of my EMF model list below:

Model
|____Network
|
|____OptimizedResult


There is a table called T_Model which will store all the attribute in

Model,Netwrok and OptimizedResult.

So I cannot map 3 classes into T_Model.

But I am not sure if it is possible to map into DB View.


Regards,

Anthony

Anthony,
Model refers to one instance of Network and one instance of OptimizedResult and you want the
features of Network and OptimizedResult to be mapped to the same table as Model. When a Model is
saved also the Network and OptimizedResult are saved.
Is this what you want?

Anthony,
To achieve this you can set the @Embedded annotation in the ereferences Model.Network and
Model.OptimizedResult.

If there are nameclashes between Network, OptimizedResult and Model then you can use
@AttributeOverrides.

Martin,

OK. I will try it.

I have another question :

In my case ,the model structure list as below:

Network
|________ProductCatalog
| |_______Product collection
|
|________CustomerCatlog
|_______Customer collection


When UI want to show product collections,
the ProductCatalog object will act as collection's
parent object to avoid getting customer collecitons.

(If no ***catalog, ContentProvider will return Network's children)


Do I have to have table to mapped ***Catalog class?

Anthony,
You can try to set @Embedded also on Network.ProductCatalog/CustomerCatalog to get it into the same
table as Model and Network. Is that whay you want/mean?

Martin,

Thank you for help.

I just learn to write my mapping file.

It seems that when a new persistable object was saved
a new record will be inserted into its mapped table.

In my case, the sample structure of my EMF model list below:

Model
|____Network
|
|____OptimizedResult


There is a table called T_Model which will store all the attribute in

Model,Netwrok and OptimizedResult.

So I cannot map 3 classes into T_Model.

But I am not sure if it is possible to map into DB View.


Regards,

Anthony

To achieve this you can set the @Embedded annotation in the ereferences Model.Network and
Model.OptimizedResult.

If there are nameclashes between Network, OptimizedResult and Model then you can use
@AttributeOverrides.

Martin,

OK. I will try it.

I have another question :

In my case ,the model structure list as below:

Network
|________ProductCatalog
| |_______Product collection
|
|________CustomerCatlog
|_______Customer collection


When UI want to show product collections,
the ProductCatalog object will act as collection's
parent object to avoid getting customer collecitons.

(If no ***catalog, ContentProvider will return Network's children)


Do I have to have table to mapped ***Catalog class?
