Hello,
I ran a query that I thought would take an hour, but instead took 14
hours to run. The consequence was it bogged down our data warehouse
and the overnight build was adversely impacted.
Is there a local setting I can set to limit the execution time my
query will take? I dont want to have a server setting and impact other
queries, just the one I am running.
I know there will be people asking about the 14 hour build and what is
it doing and so forth. I will address that but I also look to these
situations as a learning opportunity.
Thanks in advance.
Rob
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?

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?
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?
HI, 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?
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?
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 ?
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.
I were thinking, if ther was a way to restrict people(hackers) from executing transactions too frequently, my database could be much more secure. Such capability is available within My Sql. I there such a thing in sql server?
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 was asked if there was a limit on the amount of clock time that the Replication agents may be down without snapshotting the subscribers. I think that the only factor is if the MSDB database contains the necessary data to feed a restarted Replication Agent.
Hello Anybody ! 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? It's actually happening to us.Any clue?? thanks. Di.
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.
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.

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?

Currently I have around 4 million records. I have normalized the table the best I know how. I am using SQL Server 2008 r2 express running on a local instance. I am trying to create a view in the View designer. I run the query in query editor it takes just under a minute to run. When I run it in the view designer it times out in 30 sec.
If I use the following query for a Dataset and the execution takes a few seconds to show results
SELECT *
FROM dbo.ICParameter
WHERE (PatientID = @ID ) AND (LogTime > DATEADD(day, -1, GETDATE()))
ORDER BY LogTime
If I replace '99010200101' with @ID and enter '99010200101' when prompted for ID, the execution takes forever. Actually I have never got any results even after waiting for 10 minutes.
Hi all,I have a problem with a stored procedure.This stored procedure inserts around bout 500,000 records but when it is executed it takes about 15-16 hours to do so.The stored procedure is using a temporary table to do this and is also calling a function.Please let me know if there is a way to reduce the execution time.will a cursor help? Thanks, Anne.
i am currently in the process of moving a bunch of jobs into SSIS from another ETL tool. I would like to benchmark the two products against each other by comparing how long each step of an ETL process would take.
I see no way to do this in SSIS, there is the Progress tab but it doesnt list start/time and end/time. Plus I having loops and things which I want to know how long each iteration takes.
