Turn On The Query Governor Cost Limit Option For 20 Minutes?
Sep 18, 2014
I want to turn on the query governor cost limit option for 20 minutes so that queries do not run longer than 20 minutes but I could not find any info as if this option would also not allow database backup job or other maintenance jobs to run more than 20 minutes. We have backups (Via RedGate) run over 3.5 hours and others like rebuild indexes and integrity checks even more than 3.5 hours....
I have enabled the query governor on our SQL2000 SP2 server with athreshold of 3600. Now, some of the maintenance jobs fail due to thelimit being to low (e.g. one of the user databases integrity checkfails nightly).I have tried to put the command 'SET QUERY_GOVERNOR_COST_LIMIT 0' justbefore the line in the step which reads 'EXECUTEmaster.dbo.xp_sqlmaint N'-Plan etc'but it has no effect.Does anyone know how to get around this situation without usingsp_configure to change the query governor settings at a systemwidelevel?GC.
I was looking for a little insight on Resource Governor. I have a request from my manager to limit the resources a certain third party's DB can use on our system. We allow them to keep a DB on our SQL 2012 server so they can run query's to compare data to their server without linking the two machines.
I was looking into resource manager to perhaps accomplish this task but I'm not real familiar with it. If Resource governor can be used to only allow a DB named UserDB1 to use only 1GB or Memory at any one time?
Or perhaps there is another way aside from Resource governor?
I want to bring up a report via a URL and pass parameters to initialize the report parameters in the report. But I do not want the report to execute, to give the user the opportunity to change the passed report parameters. How do I turn off the &rs:Command=Render option since it is also the default?
I know that the query governor works off of estimated query plans, but the estimation is usually so far off from reality that it might as be generating a random number to determine whether a query should run.
Right now I have query governor set at 300. I've been able to run queries that take more than 10 minutes without any complaint from query governor.
What's really annoying though, is that it has also blocked queries that take less than a second to run. It blocked a query for having an estimated executing time of 338 seconds. When I set the limit up to 400, the query ran virtually instantly.
Is this just how query governor is suppose to work? Is there any way to make it work better?
I need to build TSQL query to return the Last unit Cost from my table of movement of goods SL (on CTE) but the MAX(Datalc) must be Less or Equal to my HeaderInvoice.
This is my script:
With MaxDates as ( SELECT ref, MAX(epcpond)[Unitcostprice], MAX(datalc) MaxDate FROM sl
[code]....
the problem I have right now is that the Unitcostprice of my table of goods movements has a top date greather than the date of my bill.
Example:
invoice date : 29.01.2015 unitcost on invoice line = 13,599722 Maxdate (CTE) : 19.03.2015 unitCost from my table of movement of goods = 14,075
That ´s not correct because the MAxdates > invoice date and the unitCost of 14,075 is the cost on 19.03.2015 and not just before my invoice date.
I right in thinking that if the estimated subtree cost is higher than the cost threshold for parallelism then it will use a parallel plan? If so, I've read the cost threshold is measured in minutes but is the subtree cost measured in something else, the mysterious cost number? And if so, how are the two compared?
I have 2 different queries which produce same result. I want to know which querry is better and why? The query is used to display the employee details who is handling the maximum number of project.
Queries are the following
Query A
Code Snippet
SELECT EmployeeDetails.FirstName+' '+EmployeeDetails.LastName AS EmpName, COUNT(LUP_EmpProject.Empid) AS Number_Of_Projects FROM LUP_EmpProject INNER JOIN EmployeeDetails ON LUP_EmpProject.Empid=EmployeeDetails.Empid GROUP BY EmployeeDetails.FirstName+' '+EmployeeDetails.LastName, LUP_EmpProject.Empid HAVING COUNT(LUP_EmpProject.Empid)>0 AND COUNT(LUP_EmpProject.Empid)=(SELECT MAX(Number_Of_Projects) FROM (SELECT COUNT(LUP_EmpProject.Empid) Number_Of_Projects FROM LUP_EmpProject GROUP BY LUP_EmpProject.Empid)AS sub)
Query B
Code Snippet
SELECT LUP_EmpProject.EmpID, EmployeeDetails.FirstName + ' ' + EmployeeDetails.LastName AS EmpName, COUNT(*) AS NumberOfProjects FROM LUP_EmpProject INNER JOIN EmployeeDetails ON LUP_EmpProject.EmpID = EmployeeDetails.EmpID GROUP BY LUP_EmpProject.EmpID, EmployeeDetails.FirstName + ' ' + EmployeeDetails.LastName HAVING COUNT(*)=(SELECT MAX(Number_Of_Projects) FROM (SELECT COUNT(LUP_EmpProject.Empid) Number_Of_Projects FROM LUP_EmpProject GROUP BY LUP_EmpProject.Empid)AS sub
I have a query i have been optimizing. Now runs in about 15 minutes but was wondering if there is any way tr educe the SORT cost.
Currently the high costs left are the Table insert which is 58% and the Sort cost of 36%
The inner query below is around 400million rows and aggregates to around 15,000,000 rows)
SELECT@1 = DateKey FROM dbo.DimDate WHERE TheDate = CAST(DATEADD(WEEK, -1, GETDATE() -1) as DATE) SELECT@2 = DateKey FROM dbo.DimDate WHERE TheDate = CAST(DATEADD(WEEK, -2, GETDATE() -1) as DATE) SELECT@3 = DateKey FROM dbo.DimDate WHERE TheDate = CAST(DATEADD(WEEK, -3, GETDATE() -1) as DATE) SELECT@4 = DateKey FROM dbo.DimDate WHERE TheDate = CAST(DATEADD(WEEK, -4, GETDATE() -1) as DATE) SELECT@5 = DateKey FROM dbo.DimDate WHERE TheDate = CAST(DATEADD(WEEK, -5, GETDATE() -1) as DATE)
So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.
From Books Online: • This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician. • The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.
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?
SqlDataSource1.SelectCommand = "select * from [tblproperty]";
}
else
{
SqlDataSource1.SelectCommand = "select * from [tblproperty] where " + item + "" + criteria.Trim() + "'" + txtSearch.Text.Trim() + "'";
}
}
}
Now the item contains any value from a combo box, the criteria would be having (All, =, <,>, like, <>) and txtsearch would be having the exact search field value. How can i transform it into a stored procedure so that I do not have to write 2 procedure plus i would be getting all the values back when the procedure executes?
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?

I'm creating a website for a student organization at my university. Basically, I have an Excel file with a list of contacts that the members of our organization need to be able to search on our website.
The only field that I need our members to be able to search is "contact location." So for example, a member might want to know if our organization has any contacts in Spain, so the member would type "spain" into the "contact location search" field" and would get results.
I really don't known where to turn... I need the easiest thing that would be manageable for a novice. It doesn't need to be an intense search function; just something to make the website functional (so it obviously needs to be uploadable to a server; the server has PHP capability...no idea if that has any relevance). I've been searching around all day and have come across potentials like PHP, SQL, XML, etc. but have no idea which way to turn... I have Office and Adobe Studio programs at my disposal.
Thank you all-powerful and all-knowing web gods! I owe you my deepest gratitude!
We built a Cache component that take advantage of the SQL Server 2005 query notification mechanism, all went well , we tested the component in a console application , and notifications kept coming for as long time as the console application ran.
When we initiate our Cache Component in our web service global.asx application start event , the query notification works for a few minutes , but if we came after 10 minutes or so , we stoped getting notifications from sql, the SQL Server queue is empty , and all is showing that there is nothing wrong on the DB side...
Our Cache component is a Singleton class , that perform all registrations ,catch the notification events and resubscribe for notifications.
What can be the problem? is our Cache component object are being collected by GC?
Does IIS disposes the SQL Connection that the Query notification uses?
The query below runs in sub second time if I don't call it as a stored procedure. I have looked at the execution plan for both the query and the query as a stored procedure and they are the same.

Hi - does the workload governor kick in when more than 8 concurrent operations take place on MSDE as a whole, or does it kick on each database.
Ie. if I have 8 databases within MSDE - and there is 1 operation happening on each one at any given time, will one additional operation on any of the databases invoke the workload governor across ALL databases?
I am in the process of porting over an application from Access To SQL implementing SQL Server 2005 Express. My intention is to implement this database on a full time server and upgrade to a full blown version of SQL later. Am I correct in assuming that there is not limit on the number of concurrent connections to SQL Server Express since it was stated that the "Workload Governor" has been removed? Or does something else control the number of users that can be simultaneously connected to the server.
My reason for asking is I have 7 machines that need to access the server. I also have 2 databases that need to be accessed from each machine. If there is no limit, I will keep my databases seperate. However, if there is a limit, I will most likely merge the tables into 1 db.
I am trying to load data from sql server to sybase. SQL Server is our source databse and I want to do this task in unix server using isql and bcp options.
I want to limit the changes on source tables and also I cannot use DTS or SSIS since we dont own SQL server.
Does any have any idea how to use query option in bcp. It is not direct table load. I need to run select statements with Joins in it.
Any ideas on how to script run and save results in to file and then bcp in to our sybase server.
I am not suposed to craete any views on source db. So just need to run sql statements and take the results to text file.
I'm working on a VB.NET project where we are intending to use MSDE as ourback-end database. The actual number of users is expected to be low and Idon't have any concerns as to whether MSDE will be up to the job (most ofthe time). I'm aware that if we end up with lots of users connecting to oursite at once (which may happen as certain times in the year when people needinformation for deadlines) then the performance governor in MSDE will kickin and slow everything down.What I don't know is how do I find out whether the performance governor haskicked in?I would like to know how to monitor this so we can make an educated decisionas to when we need to migrate to a full version of SQL Server (if at all).Can anyone point me in the right direction for finding this out?thanks,Brian Cryer.
What is the reason everything here executes except the very last "INSERT INTO forums_UsersInRoles VALUES ((@@identity),11) "? IF I change the order of the last two queries it is the other one (now last) that is not executed. Is there a limit to how many you can run at a time?
strSQL = " BEGIN INSERT INTO forums_Users (UserName, Password, Email) VALUES ('" & request.form("UserName") & "','" & Request("UserPassword") & "','" & Request("UserEmail") & "'); INSERT INTO forums_UserProfile (UserID) VALUES (@@identity) ;INSERT INTO forums_UsersInRoles VALUES ((@@identity),11) END;"
I want to run a query overnight through the SQL agent using osql. However I need to turn off the print header option that you normally turn off through the advanced options tab in the Query Analyzer. Does anyone know if this is possible?? Many Thanks in advance..
