Report - Serial, Computer Name, & Last Client Date

Sorry for the basic SQL question, but I need a report that only shows 3 columns for all computers in CMS - computer name, hardware serial number and last date that computer communicated to CMS.  I think Client Date is close enough as I need the day it last communicated, the exact time isn't as important.

I have this report that has the info I need in it, but it also has about 15 other columns my boss doesn't want to get.  How can I narrow down the report to only show those 3 columns?

select * 
 
FROM dbo.Inv_AeX_AC_Identification ac
left join (SELECT     _ResourceGuid, MAX([user]) AS [primary user]  
FROM         dbo.Inv_AeX_AC_Primary_User   
WHERE     ([User] IS NOT NULL) AND ([User] <> '') 
GROUP BY _ResourceGuid  ) Prime                          
on ac._resourceguid =  Prime._ResourceGuid
LEFT OUTER JOIN  dbo.Inv_Global_Windows_Users  T20                                                                                        
ON Prime.[primary user] = t20.[USERID] 
LEFT OUTER JOIN dbo.Inv_Global_User_General_Details  T10                                                                                        
ON t20._ResourceGuid = T10._ResourceGuid 

Thank you.  I wish I had the time to truly understand how to do reporting in CMS, or if their was a better web interface for building reports.  Our Mac Management tool is so much more user friendly in that regard.
