how can I get the execution time in millisecond of an MDX query in SSAS?For sql we can get it by:
Code:
set statistics time on
--query----
set statistics time off.But I am not getting anything for MDX.
I have a view in SQLServer 2005. It took 30 sec. to finish. Then I deleted 4500 records from one table that is used in view. It took 90 sec. to finish now. I did a comparison on Actual Execution Plan between before I deleted data and after I deleted data, they are almost same, only different is Actual Number Rows become less after deleted data. So, I wonder why data become less but time become more. When I look closely on the Actual Execution Plan, the ridiculous thing is, there are only Estimated Operation Cost on each step, no Actual Operation Cost. I guess there are something wrong with optimizer because reuse same Execution Plan, but how can I tell which step wrong without Actual Operation Cost.
Thanks!

I have two queries yielding the same result that I wanted to compare for performance. I did enter both queries in one Mangement Studio query window and execute them as one batch with the actual query plan included.Query 1 took 8.2 seconds to complete and the query plan said that the cost was 21% of the batchQuery 2 took 2.3 seconds to complete and the query plan said that the cost was 79% of the batch.The queries were run on my local development machine. I was the only user. No other programs were running at the time of this test. The results are repeatable.I understand that the query with the lowest cost is not necessarily the fastest query. On the other hand, the difference is quite big. The query that has approx. 80% of the cost takes 20% of the time and the other way around. I have two questions:
Is such a discrepancy normal?Can conclusions be drawn from the cost distribution? For instance, does the query that takes 8.2 seconds but only costs 21% scale better?
A query that runs in a second or so in Query Analyzer requires 20 seconds in a linked Access Project.
What's the secret of MS_Access poor performance, and can it be improved?

How to get the execution time of a query in sql server 2000?
Thanks in advance
Hi All
Is there anyway you can estimate the execution time/cost of a query prior to actually executing it?

hello friends,
how can we findout the query execuetion time in mili seconds.
for sample
select * from tabelname;
how much time it will take to retrive result.
thanks.
Hell All,
Following query takes 7 minutes to execute while using search criteria as shown below in blue text(ie. IN(2006,2007)
if criteria changes to =2006 as shown in 2),this takes 2minutes
But I want expected output as in query 1) in less time.
How to optimize following query for execution time?

Hello,I ran a query that I thought would take an hour, but instead took 14hours to run. The consequence was it bogged down our data warehouseand the overnight build was adversely impacted.Is there a local setting I can set to limit the execution time myquery will take? I dont want to have a server setting and impact otherqueries, just the one I am running.I know there will be people asking about the 14 hour build and what isit doing and so forth. I will address that but I also look to thesesituations as a learning opportunity.Thanks in advance.Rob
View 3 Replies View RelatedI have problems sometimes with a package.
There is and SQL Agent job that starts a package (from a file system using cmd command). Usually job takes 8-10 minutes. But sometimes it get stuck for a long time (1+ hour).
DTexec process can be found with procmon, but it seems it just not doing anything (And package is not logging to file Start of the execution) After long wait it just runs a package quickly.
I've moved a package to SSIS catalog to try to get more detailed logging, but with no luck.
Job starts at 1 PM, package execution starts at 1:49 PM. Without any messages about the execution in SSISDB log.
First I've thought it might be long validation problem, but when package executes validation messages are there and they perform quick.
I have created 2 tables in a database which are mostly similar, the table1 will execute with more speed (take only less than or equal to 1 sec) but the table2 will take 4 or 5 secs to execute the query,moreover the similar datas was presented in both the tables. the eg:- query that i have executed is select max(c_code) from table1 and select max(c_code) from table2, the first one take less than 1 sec and the second one take more than 4 or 5 secs, also there is a procedure i hve written to update both the tables, and i got the time out error, if the table1 alone is updated using the procedure it is OK but the table2 alone is updated using the procedure the time out error will be shown, pls reply the reason for this problem as early as possible, it will be a grateful if anybody reply for this trouble?

Hi all,
I have a query, rather complex one to deal with more than 1 million rows, used to run 40 minutes in SQL Server 2000 in query analyzer. Now, it has been 10 hours in SQL Server 2005 in management studio. And still has not finished yet! Anything can go wrong here. Basically nothing changes, except for I have my server upgrade from SQL Server 2000 to SQL Server 2005. Seems something is wrong crazy in SQL Server 2005. Any suggestions?
Thanks,
Ning
The benefit of the actual execution plan is that you can see the actual number of rows passing through each step - compared to the estimated number of rows.But what about the "cost percentages" ?I believe I've read somewhere that these percentages is still just an estimate and is not based on the real execution.Does anyone know this and preferable have a link to something that documents it?Thanks
View 1 Replies View RelatedHI,
I have an interesting situation. I have created a stored procedure which has a select union query and it accepts some parameters. When I execute this procedure it takes 8 minutes. When I copy the script in stored procedure and run it directly in Query Analyzer it takes 2 1/2 minutes?? Same numbers of rows are returned either way in the result set with about 13,000.
I cannot figure this out and it is almost the same thing except that in Query Analyzer I declare the parameters variables and its values?
Any feedback would be appreciated!
Thanks in advance...
I am using a stored procedure that is behaving badly - the subtree cost is about 2000 and it takes between 3-4 seconds to run, and sometimes it takes over a minute to run. I have made some optimizations that cause the stored procedure to run in generally under 1 second (at most under 2 seconds), but the subtree cost of it jumps to 4000!! All of this while the server was experiencing similar load (the tests were done within minutes of each other).
I know that the subtree cost is a way to gauge the performance of a query against other queries, but I have typically seen the cost go in the same direction as the execution time (they both go up or the both go down).
How does SQL Server determine the cost (I know that is based on statistics, but I was wondering if anyone had more details)? Is it more important to have a lower subtree cost, or a lower execution time? Am I going to get into trouble later with this high subtree cost?
I would appreciate any help on this matter.
If I have 6-8 queries running in parallel, Whether having a Single connection Manager (for the same source) for all the Extract performs faster or having Distinct Connection Manager for each of the extract performs faster ?

Hello everyone!
Whenever i insert a new row i would like to have the current date and time in the column DATE. How is that possible?

I want to save every query executed from a given software, let's say Multi Script for example, and save in a table query text, execution time and rows count among other possible useful information. Right now I've created a sp and a job that runs every 1 milliseconds but I can't figure out how to get execution time and rows count. Another problem with this is that if the query takes too long I end up with several rows in my table.
View 5 Replies View RelatedHaving a SQL Server 2012 Enterprise (x64) on a Windows 2012 R2. We need to know, a reliable way, the number of processor sql server is using at a give time. We already know how many total processor are available to sql by getting info from sys.dm_os_sys_info.
For instance, a server has 40 processors, we want to know how many of those are being used at a given time. Since the load on the server may not be that high, we would like to know how many processors we can eliminate and the load will still be unaffected.
After watching the server performance for a while, we are predicting we may only need 16. But we would like to get some statistics before we reduce it to this number.
Hi,
I have built a Sales Forecast model to predict the sales
value.
Along with making historic predictions for previous time
periods I also want to retrieve the actual sales values for those periods.
How can I achieve this in a time series model?
I also would like to know how do mining models store the data.
Do they store the data in the same table/view format
as their respecive data source view or in the Model Content format.
Is there a way to keep track in real time on how long a stored procedure is running for? So what I want to do is fire off a trace in a stored procedure if that stored procedure is running for over like 5 minutes.

I want to get the execution time of a query, I mean I will run the one sql statement like this " SELECT * FROM tblname WHERE field1 = '009' and then I want to get from my program execution time of this query. I think I just keep the sys time before run it and compare with sys time when finished it. But I don't like this one, So, can I get the execution time from sql server by running their sys s-procedure or something like.
Thanks.
Is it possible that a stored procedure runs slower when called by an application,and runs faster when executed as 'exec xxxxx' on query analyzer?

i observed a strange problem in my production setup. i have a job which updates usage metrics (for reporting) which is scheduled to run once in a day. (the job invokes an sp to do this. the sp refers two tables to retrieve/update information, say TableA and TableB).
the job normally takes an average of 25 seconds to complete. all of a sudden the job execution time increased to 6 minutes and 52 seconds. now, the average job execution time is 8 minutes. there is no table/sp change in the DB
the only thing i observed is that one of the tables referred by the sp has 30,000 records added to it, on the day from which the job execution time increaed to 6 minutes.
i have updated the statistics on the Table, but the execution time remains unchanged. can any one suggest any possible causes for such a scenario.
i expect a few hints with which i can explore my production DB and find out the causes for the increased execution time for the sp.
Pl discuss...
Thanks in advance
Hello,
What is the built-in-function to check the Query execution time in milli seconds.

When I manually run the ssis package i.e. by clicking the run button) it takes about a second to complete.
This package is scheduled to run as a job every two minutes. In the history window of jobs in sql server 2005, I see that each time the job takes about 31 seconds. Do you know why it takes 31 seconds where it should take about 1 second to complete?
Thanks
I am trying to run a SQL Server procedure from a program in ASP.Net 2005. This procedure is to insert around 500 records(can exceed every month) in a table with 4 columns and is also containing another small procedure also. When this procedure is executed from online server, it shows timeout message as:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
But when the same procedure is run from SQL Query Anayser it excute within seconds. How can i solve this problem , i need this solution urgently too.
Hope to get ur response soon.
Hi,

I have a query that is taking 30-40sec to execute in a SQL Server 2005 Standard Edition database. However, when I use that same query to create a named view, and then try to open the view, I get the following error (eventually) after I attempt to open the view:
Executed SQL Statement: select ....
Error Source: .net sql data provider
Error Message: Timeout expired. The timeout period elapsed prior to completion of the operation, or the server is not responding.
Is there a server or set parameter that I can adjust that will allow my view to complete execution?
Hi!
How can i find the querey execution time in sql 2000.
If u have any article or books online please suggest me.
Thanks!
