Hi samira.emami,gbritton has a good point. I would take a further look into the IO statistics by using the command SET STATISTICS IO ON and take a look at the Output in the Messages section of your query results.More information on that here:https://msdn.microsoft.com/en-us/library/ms184361.aspxAlso, have you checked the execution plan?This will give you insight into the most intensive operations within your query and give you an opportunity to see if a change could improve the execution.Here's a nice video by Jes Borland from Brent Ozar Unlimited going over execution plans:https://www.youtube.com/watch?v=I-jjgZ51_SwHope this helps!
