Hi,
I've not used olingo/odatav2. All my developpement was based on
olingo/odatav4.
Maybee have a look to examples available directly in olingo source code. It
helps me a lot :

Hi,
Our main requirement is adding new column with out changing entity class .
We may use jpa ,may be Apache odata olingo...but essentially we need to add
column with out changing code ...
Odata has several opportunities to work with data..but how can we add new
column...
Feel free to call me...or any number where I can call and understand...
Thanks Atanu

Thanks for the reply.
Suppose we have one entity with two fields...now using odata Apache oilingo
can I add one more column to the existing entity with out changing
code...may be some changes in meta data would be enough...at the same time
I will get new column in db for the table.
Thanks Atanu
