entity framework - how to create a EF data model like a sql server view -

any suggestions ?

thanks reading.

edit: tried sql server view got fallowing error when want insert sql server view:

msg 4406, level 16, state 1, line 1 update or insert of view or function 'viewname' failed because contains derived or constant field.

you need create database view + stored procedures insert, update , delete. map view new entity , map imported stored procedures insert, update , delete operations entity.

you don't need database view - can write query straight edmx using definingquery requires manual modification of edmx. default ef tools delete manual modification 1 time run update database again.

even defining query still need stored procedures. there no other way create entity based on defining query (view imported defining query) updatable.
