Whoot!

I remember IIF() from the VFP days. The CASE syntax is damn fugly in comparison.

We can't enjoy any of these unless we create a storeproc to run them...

And btw, every time I have to write a stored procedure because there's a feature I needed missing or performed inefficiently in EF. I'm at loss... what good does it brings over standard strong typed dataset if you only use storeproc to perform database access? /rant

And unless I'm wrong, you could also use table functions, and still get strong typing.

This is exactly why I wonder what does I gain by using EF. I could just use System.Data.ODBC.* (Note that in MSSQL vNext, ODBC will become first class citizen and OLEDB will be dropped in vNextNext) to get strongly typed dataset to get virtually all what EF offers, without concern about performance issues.
