CDS modeling problem

Hi all,

I'm trying to figure out how to model my entities..

I have a big table that contains all my entities, and a smaller one that contains only some of the entities with some more data (for the same entities)

In MSSQL I did LEFT JOIN to get all entities (with or without the extra data)

I made a small example of my model in CDS:

@Catalog.tableType: #COLUMN  entity FullEntity  {       key ID : Integer; //My Key for the entities       anyField : String(50);  };  entity DescriptiveEntity  {       key FullEntID : Association [1..1] to FullEntity {ID} ; //the ID from the fullEntity table       Description : String(50);  };

How can I write a view, that will basically do:

SELECT * FROM FullEntity as F     LEFT JOIN DescriptiveEntity as D     ON F.ID = D.FullEntID;

The opposite is very easy but gives me basically a right join

VIEW RightView as select from DescriptiveEntity
{      DescriptiveEntity.FullEntID.ID,      DescriptiveEntity.FullEntID.anyField,      DescriptiveEntity.Description
};

Thank you,

Yaron
