Measuring the cpu and ram consumption of a given query in sql server

Question

hello there how you doing and am new to this sql server forum and i suddenly popped to ask questions related to sql server
and my question goes like this
in sql server i have table called testt and it have more thna10000000 records
and i have written a query select * from testt limit 9000000; and what i want is to measure the
CPU consumption of this given query=???????????????
and
RAM consumption of this given query=???????????????
Time consumption of this given query=?????????????? this i will get it from the result bar but i don't know whether it is correct or not
any help on this it may be query, tool or configurations all are acceptable and appreciated
10Q for letting me ask questions and feeling freely.

Answer 1

Please check these queries and this may helps you to get whats happening on with CPU currently..
SELECT getdate() as "RunTime", st.text, qp.query_plan, a.* FROM sys.dm_exec_requests a CROSS APPLY sys.dm_exec_sql_text(a.sql_handle) as st CROSS APPLY sys.dm_exec_query_plan(a.plan_handle) as qp order by CPU_time desc
Top 50 CPU usage :
SELECT TOP 50 st.text
               ,st.dbid
               ,st.objectid
               ,qs.total_worker_time
               ,qs.last_worker_time
               ,qp.query_plan
FROM sys.dm_exec_query_stats qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) st
CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp
ORDER BY qs.total_worker_time DESC

Activity Monitor and sp_who2 active also will give some idea...

================
Execute this script and and start doing your analysis in your server so that you will get more idea how its working and all the details...
Sample CPU Test : Dont try this in production and try this in your test or Dev server..
-- Query to Keep CPU Busy for 2 0 Seconds
DECLARE    @T DATETIME, @F BIGINT;
SET @T = GETDATE();
WHILE DATEADD(SECOND,20,@T)>GETDATE()
SET    @F=POWER(2,30);
You can easily change the parameter in the DATEADD and can make it run for 50 seconds.
