SQLServer: What am I running anyway?

Microsoft has enough crazy patches and service packs to drive a dba nuts! (that said, Oracle, Mysql, and most other databases have their fair share as well).

Question is though, what version are we running anyway? For those that don't come from the Microsoftie world, the whole daily build number thing in the version is a little out of control.

IE:

Server A:

1> SELECT @@VERSION
2> go
Microsoft SQL Server 2005 - 9.00.2164.00 (X64)
Jun 14 2006 12:39:07
Copyright (c) 1988-2005 Microsoft Corporation
Enterprise Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 1)

Server B:

1> SELECT @@VERSION
2> go

Microsoft SQL Server 2005 - 9.00.2047.00 (Intel X86)
Apr 14 2006 01:12:25
Copyright (c) 1988-2005 Microsoft Corporation
Enterprise Edition on Windows NT 5.2 (Build 3790: Service Pack 1)

So, what is the difference between these two servers?

Besides the obvious X86 vs X64, the only really difference is the nightly build number. They are both actually SP1.

So we should really be checking this way:

Server A:

1> SELECT SERVERPROPERTY('productversion'),SERVERPROPERTY('productlevel')
2> GO

9.00.2047.00 SP1

Server B:

1> SELECT SERVERPROPERTY('productversion'),SERVERPROPERTY('productlevel')
2> GO

9.00.2164.00 SP1

Just another dorky pet peeve of mine :)
