SQL Script to Compare SQL Server Settings

How to Compare SQL Server Settings ?

This is pretty simple, we can run sp_configure on individual server and can do the comparison manually but what if we can have a script where we just need to supply the servername, that that script will automatically do a comparison and let you know the results.

At times while debugging an issue or setting up a environment we have to compare the server configurations across the SQL Servers. So this script made that pretty easy.

-- Enable Server Remote adhoc queries at server level
sp_configure 'show advanced options', 1
reconfigure
go      
sp_configure 'Ad Hoc Distributed Queries', 1
reconfigure
go
-- End of Server settings
      
      declare @ServerNames VARCHAR(1000) 
set @ServerNames = '<Enter Server Names here> and use comma (,)as server delimiter'

/*
Parameters 
@ServerNames = The servers configurations to compared should be passed in the parameter as a comma seperated value as shown in the below usage.
               This parameter cannot be blank. 

Usage : set @ServerNames ='Server1,Server2,Server3'
