You should use a stored procedure mapped to a ‘function’.

• Create a stored procedure which returns your data.
• Update your EF model (Update from database...)
  • Add the stored procedure to the model
• Right click on the EF designer and choose Add function import... (it’s one of the top options), which will open the function import dialog.
• Enter the name that you want the function to be called, and the return type. The easiest way is to click the button at the very bottom (‘show columns’ or something) and then choose Create new complex type. A class will be created that contains a result of the stored procedure.

Now you’ll have a function on your ObjextContext, named according to the choices you made. You call it very simply:

var result = objectContext.MyStoredProcFunction(a, b, c);
return result;
