MSDE 2K vs SQL2K

Hello,
For my application I need to know how I can see the difference (by query) between a MSDE and SQL server.
I need to know if the server is MSDE or SQL...
Is there any information in the system tables where I can see it?
Thank a lot for your informationsI believe this will do it

select @.@.version|||This query returns a string wich described the version of the server.
I'm looking after a number version or something else wich does the same thing. I don't know if it exist... Maybe i'm looking for something that doesn't exist?|||select @.@.version on my pc gives this

Microsoft SQL Server 2000 - 8.00.760 (Intel X86) Dec 17 2002 14:22:05 Copyright (c) 1988-2003 Microsoft Corporation Enterprise Evaluation Edition on Windows NT 5.0 (Build 2195: Service Pack 4)

I believe you can check whether or not your pc is a MSDE or SQL server 200o etc using this.

I just forgot this ... from the Holy Book (SQL server Books Online)
