SQL Server Management Studio, how to get execution time down to milliseconds

Question

What you want to do is this:

set statistics time on

-- your query

set statistics time off

That will have the output looking something like this in your Messages window:

SQL Server Execution Times: CPU time = 6 ms, elapsed time = 6 ms.

Turn on Client Statistics by doing one of the following:

• Menu: Query > Include client Statistics
• Toolbar: Click the button (next to Include Actual Execution Time)
• Keyboard: Shift-Alt-S

Then you get a new tab which records the timings, IO data and rowcounts etc for (up to) the last 10 exections (plus averages!):

I was struggling with that until i found this...

Also, if you open the Properties window you may find some magical "Connection elapsed time" that may give you some execution time... Hope it helps...

To get the execution time as a variable in your proc:

DECLARE @EndTime datetime
DECLARE @StartTime datetime 
SELECT @StartTime=GETDATE() 

-- Write Your Query


SELECT @EndTime=GETDATE()

--This will return execution time of your query
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in millisecs] 

AND see this

Measuring Query Performance : "Execution Plan Query Cost" vs "Time Taken"

I was after the same thing and stumbled across the following link which was brilliant:

http://www.sqlserver.info/management-studio/show-query-execution-time/

It shows three different ways of measuring the performance. All good for their own strengths. The one I opted for was as follows:

---

DECLARE @Time1 DATETIME

DECLARE @Time2 DATETIME

SET @Time1 = GETDATE()

-- Insert query here

SET @Time2 = GETDATE()

SELECT DATEDIFF(MILLISECOND,@Time1,@Time2) AS Elapsed_MS

---

This will show the results from your query followed by the amount of time it took to complete.

Hope this helps.

I don't know about expanding the information bar.

But you can get the timings set as a default for all queries showing in the "Messages" tab.

When in a Query window, go to the Query Menu item, select "query options" then select "advanced" in the "Execution" group and check the "set statistics time" / "set statistics IO" check boxes. These values will then show up in the messages area for each query without having to remember to put in the set stats on and off.

You could also use Shift + Alt + S to enable client statistics at any time

You can try this code:

USE AdventureWorks2012;
GO
SET STATISTICS TIME ON;
GO
SELECT ProductID, StartDate, EndDate, StandardCost 
FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;
GO
SET STATISTICS TIME OFF;
GO
