There are two different command you can use to check if you are running 32-bit or 64-bit version of SQL Server.

Using @@VERSION:

You can user @@VERSION system variable to determine edition and architecture of SQL Server as below:

SELECT @@VERSION

Result Set:

Microsoft SQL Server 2012 (SP1) – 11.0.3000.0 (Intel X86)

       Oct 19 2012 13:43:21

       Copyright (c) Microsoft Corporation

       Developer Edition on Windows NT 6.0 <X86> (Build 6002: Service Pack 2)

(1 row(s) affected)

This command returns both SQL Server and Operating system information. In the first line you get information about SQL Server, it's version and architecture. Here, x86 = 32-bit architecture and x64 = 64-bit architecture. Same it true for operating system.

Using SERVERPROPERTY():

We can also user SERVERPROPERTY() function to get information about SQL Server Edition and architecture.

SELECT SERVERPROPERTY('Edition')

Result Set:

Developer Edition

(1 row(s) affected)

From the output we can see that it's a Developer Edition instance and architecture is 32-bit. If it is 64-bit then '(64-bit)' will be appended to edition. i.e. For 64-bit the output will be 'Developer Edition (64-bit)'

Hope This Helps!
