LongestRunningQueries.vbs - Using A VB Script To Show Long-running Queries, Complete With Query Plans
Jul 17, 2006
Try this script to see what queries are taking over a second.
To get some real output, you need a long-running query. Here's one
(estimated to take over an hour):
PRINT GETDATE()
select count_big(*)
from sys.objects s1, sys.objects s2, sys.objects s3,
sys.objects s4, sys.objects s5
PRINT GETDATE()
Output is:
session_id elapsed task_alloc task_dealloc runningSqlText FullSqlText
query_plan
51 32847 0 0 select count_big(*) from sys.objects s1, sys.objects s2,
sys.objects s3, sys.objects s4, sys.objects s5 SQL Plan
Clicking on SQL opens the full SQL batch as a .txt file, including the PRINT
statements
Clicking on Plan allows you to see the .sqlplan file in MSSMS

Title: Using a VB Script to show long-running queries, complete with query
plans.
Today (July 14th), I found a query running for hours on a development box.
Rather than kill it, I decided to use this opportunity to develop a script
to show long-running queries, so I could see what was going on. (Reference
Roy Carlson's article for the idea.)
This script generates a web page which shows long-running queries with the
currently-executing SQL command, full SQL text, and .sqlplan files. The full
SQL query text and the sqlplan file are output to files in your temp
directory. If you have SQL Management Studio installed on the local
computer, you should be able to open the .sqlplan to see the query plan of
the whole batch for any statement.

Hello All
I have queries which take over 30 secs to run, which I wish to monitor.
Currently, I am monitoring using sql profiler.
Is there any way of setting up mail to e-mail me when such a query happens.
Could I set up an Alert, or is there some other method.
I want to be able to react to these events faster before the users complain.
I am using sql server 7 enterprise and I have exchange set up.
Any help would be great

When I execute this stored proc it runs for more than 5 minutes. Is there anything i can do to speed it up? Maybe there is a faster way of writing these queries?

Is there any way to measure the progress of a long running query,
for instance, to find where in a query plan a query is in SQL 7.0?
I have a query I am running that is currently 2 1/2 hours into the
query. Since it's joining three large tables, one with 42 million rows
and two with 7 million rows, I'm expecting the query to take a
while. However, I have no way of estimating exactly how long
it will take. Before I ran it, I optimized it the best I could in
Query Analyzer using an estimated query plan, making sure I had
all the right indexes, etc. I've been trying to use the estimated cost
to project query time, but that hasn't been working since queries
with similar costs can take radically different amounts of time to
execute.
Now I'm sitting here waiting, wondering if the query is just taking
too long, and I should stop it and work on optimizing it some more
(since I will have to run a couple more queries like it), or let it
finish. But I have no clue how close it is to finishing. I've tried looking
at the Physical I/O given by sp_who2 and then trying to calculate the
number of pages it would have to read if it had to read everything
from disk, then estimating it's progress by that, but this seems dubious
at best, since I don't know a whole slew of factors (ie: how many
pages are being read from the cache, is my page calculation correct,
etc).
So, does anyone know of any way to figure out how soon a long
running query will finish in SQL 7.0?
Thanks.

I can't seem to find a step-by-step guide to how to detect orcontinuously monitor for long-running queries that is suitablefor a comparative SQL Server novice. I know that it is possibleto monitor for such with other database products - can anyoneenlighten me as to how this is done with SQL Server? Ideally,I'd like to snapshot running queries (preferably with querytext) at a particular instant via a script, although any helpto show what queries are running at an instant will be muchappreciated. Any ideas?__________________________________________________ ___________Are you Catholic ?http://www.CatholicEmail.com100s of FREE email addresses --->http://www.UltimateEmail.comSend an Online Greeting Card http://www.UltimateEcards.com

Here's a little SP to break up those long-running, massively-locking, bring-app-to-a-halt queries. By default it does 500 rows at a time and allows for a maximum SQL query size of 4000 characters; it should be trivial to adjust those.
Cheers

Here I am can not know how tackle and do reaserch on the same.
Question infront me as:
1. why timeout not happen on com+ components.

All -
I am using SQL Server 2005 and I have an endpoint that exposes some stored procedures as web-methods in the endpoint.
One particular stored procedure I have exposed takes a long time to execute: about 10 - 15 minutes. While, it is OK, that this stored procedure takes this long, it is not desirable for the HTTP Request that executed this proc to not wait for that long.
What I want to be able to do is to call the stored procedure and have the call return immidetaly but the stored proc continues what its doing. I will call another stored proc at a later time to retrive the result of the first stored proc. The first proc will store its results in a temp table. I am thinking of using SQL Server Service Broker to achieve this.
Is there a better a way to achieve this? And how does SQL Server process the Service Broker requests, i.e., I dont want the query to be executed when the server is busy. Are there any hints that I need to give to Service Broker to be able to do this?
Thanks.

If I start a long running query running on a background thread is there a way to abort the query so that it does not continue running on SQL server?
The query would be running on SQL Server 2005 from a Windows form application using the Background worker component. So the query would have been started from the background workers DoWork event using ado.net. If the user clicks an abort button in the UI I would want the query to die so that it does not continue to use sql server resources.
Is there a way to do this?
Thanks

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.
Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.

I have a pretty complex query that aggregates lots of data and inserts multiple rows of that data into a reporting table. When I call this SPROC from SQL Server Management Studio, it executes in under 3 seconds. When I try to execute the same SPROC using .NET's SqlCommand object the query runs indefinitely until the CommandTimeout is reached. Why would this SPROC behave differently with the same inputs, but being called from .NET? Thanks for your help!

Hi,
I'm trying to optimize a long running (several hours) query. This query is a cross join on two tables. Table 1 has 3 fields - ROWID, LAt and Long. Table 2 has Name, Addr1,Addr2,City,State,Zip,Lat,Long.
Both tables has LatRad - Lat in radians, LonRad- Lon in Radians. Sin and Cos values of Lat and Lon are calulated and stored to be used in the distance formula.
What I'm trying to do here is find the nearest dealer (Table 2) for each of Table 1 rows. The Select statement takes a long time to execute as there are about 19 million recs on table 1 and 1250 rows in table 2. I ran into Log issues- filling the transaction log, so I'm currently using table variables and split up the process into 100000 recs at a time. I cross join and calculate the distance (@DistValues) and then find the minimum distance (tablevar2) for each rowid and then the result is inserted into another Table (ResultTable).
My Code looks like this:
Declare @DistValues table (DataSeqno varchar(10),Lat2 numeric(20,6),Lon2 numeric(20,6),StoreNo varchar(60), Lat1 numeric(20,6),Long1 numeric(20,6),Distance numeric(20,15))
Declare @MinDistance table (DataSeqno varchar(10) primary key,distance numeric(20,15))
Insert into @DistValues
Select DataSeqno,T.Lat Lat2,T.Lon Lon2,S.StoreNo,S.Lat Lat1,S.Long Long1,
distance=3963.1*Case when cast(S.SinLat * T.SinLat + S.CosLat * T.cosLat * cos(T.Lonrad - s.Lonrad) as numeric(20,15)) not between -1.0 and 1.0 then 0.0 else acos(cast(S.SinLat * T.SinLat + S.CosLat * T.cosLat * cos(T.Lonrad - s.Lonrad) as numeric(20,15))) end
from dbo.TopNForProcess T , dbo.Table2 S where Isnull(T.Lat,0) <> 0 and Isnull(T.Lon,0)<> 0
Insert into @MinDistance
Select DataSeqno,Min(distance) From @DistValues Group by DataSeqno
Insert into ResultTable (DataSeqno,Lat2,Lon2,StoreNo,LAt1,Long1,distance)
Select D.DataSeqno, D.Lat2, D.Lon2, D.StoreNo, D.LAt1, D.Long1, M.distance from @DistValues D Inner Join @MinDistance M on D.DataSeqno = M.DataSeqno and D.Distance = M.Distance
I created a View called TopNForProcess which looks like this. This cut down the processing time compared to when I had this as the Subquery.
SELECT TOP (100000) DataSeqno, lat, Lon, LatRad, LonRad, SinLat, cosLat, SinLon, CosLon FROM Table1 WHERE (DataSeqno NOT IN (SELECT DataSeqno FROM dbo.ResultTable)) AND (ISNULL(lat, 0) <> 0) AND (ISNULL(Lon, 0) <> 0)
I have indexes on table table1 - Rowid and another one with Lat and lon. Table2 - Lat and Long.
Is there any way this can be optimized/improved? This is already in a stored procedure.
Thanks in advance.

The query show below is designed to use seasonal profiles to compute 53 weeks of forecast data and then from that compute the number of weeks of supply of each item at each location. The query works but the volume of data produced (20+M rows) is substantial. If I limit the CTE to a single location, it run is 2 seconds and returns 41,000 rows. But when run for all locations and items, it runs for more than 4 hours. Would I do better converting the CTE to a sub-query and adding an index to improve the performance of the main query?
WITH Forecast AS
(SELECT Location_Idx
,Item_Idx
,Week_Code
,(CAST(AnnualQty AS DECIMAL(9))/53.0)*[Profile] AS fcst
FROM dbo.FactReplenishmentProfile rp
INNER JOIN dbo.FactSeasonalProfile sp
ON sp.SeasonalProfile_Idx = rp.SeasonalProfile_Idx
)
SELECT fcst1.Location_Idx
,fcst1.Item_Idx
,fcst1.Week_Code
,fcst1.fcst AS WeekQty
,SUM(fcst2.fcst) AS CumQty
FROM Forecast fcst1
INNER JOIN Forecast fcst2
ON fcst2.Location_Idx = fcst1.Location_Idx
AND fcst2.Item_Idx = fcst1.Item_Idx
AND fcst2.Week_code <= fcst1.Week_Code

I am having a problem executing long running queries from an ASP applicationwhich connects to SQL Server 2000. Basically, I have batches of queries thatare run using ADO in a loop written in VBScript. This works pretty welluntil the execution time of a single query starts to exceed some threshold,which I am trying to narrow down. I can typically run 2 - 10 queries in aloop, with the run time being anywhere from under a minute to an hour ormore. Now that this application is being subjected to run against some largedatabases (25 - 40G), I'm having problems getting the application tocontinue beyond the first query if it takes a while to run.I used SQL Profiler to try to diagnose what was going on. I can see thequery executes to completion, but immediately after completing I can see an"Audit Logout" message, which apparently means that the client hasdisconnected. The query durations vary from 45 or 50 minutes to up to over90 minutes. I have the ADO connection and query timeouts set to very largevalues, e.g. 1000 minutes, so I can't think its that. My guess is that thereis some IIS setting or timeout that I am running up against and theconnection to SQL Server is just dropped for some reason.The configuration isNT 4.0 SP6SQL Server 2000 SP3IIS 4.0Internet Explorer 5.5I'm only running into this problem on the very largest databases we runagainst. The vast majority continue to function properly, but this is goingto happen more often as time goes on the databases continue to grow in size.Any advice is appreciated,-Gary

I have a simple update statement that is running forever in SQL 2005 but works fine in SQL 2000. We have a new server we put SQL 2005, restored db. The table in question WEEKLYSALESHISTORY I even re-indexed all the indexes and rebuilt the stats as well. But still no luck, still running extremely long. 1 hour 20 minutes.
I'll try to give you some background on these table. Weeklysalehistory has approx 30 fields. I have 11 indesxes set up weekending date being one of them. And replication control has index on lasttrandatetime as well. So I think my indexes are fine.
/* Update WeekEnding Date for current weeks WeeklySales Records */
Update WeeklySalesHistory set
weekendingdate =
(SELECT LastTransDateTime from ReplicationControl
where TableName = 'WEEKHST')
where weekendingdate is null
Weekly sales has approx 100,000,000 rows
Replication control has 631,000 (Ithink I can delete some from here to bring it down to 100 or 200 records) Although I don't think this is issue since on 2000 has same thing and works fine.
I was trying to do this within SSIS and thought that was issue. I am new so SSIS but it runs long even if I just run it as a job with this simple Update statement so I think its something with tables, etc that is wrong.
One thing on noticed if I look at the statistics in SQL Server Management studio there is a ton of stats. some being statistics on indexes which makes sense then I have a ton of hind_113_9_6 and simiiar one like this. I must have 90 or so named like this. Not sure how to check on SQL 2000 all the stats to see if they moved over from there or what. I checked a few other tables and don't have all these extra stats. Could this be causing the issue do I need to delete all these extras? Any help would be greatly appreciated.

Just curious if there's a reason why everytime I try to apply the Microsoft SQL Server 2005 Express Edition Service Pack 2 from Windows Update that it will sit at "Installing" and appear to do nothing (no hard drive activity, but the MSI and setup processes are chewing a little bit of CPU time). How long should I give this update to complete? I am running a 2-CPU dual-core Xeon 3.0GHz w/ 2GB of RAM setup, so I would have thought it would be completed very quickly. :(
Edit:
Disregard; I had to wait for a full 15 minutes! :O

Hello:
We are running some test on our application which involves long-running transaction in an application that was purchased from a vendor. It is a PB
and we don't have access to all of the code. We are not sure why it runs so slow when we start this long_running process. We are not sure if they are using a stored procedure or not.
We ran updaet statistics becuase alot of data was added before we kicked off the process. We want to capture all of the sql code that is running so we can perhaps add indices.
Under EM, we click on the thread and can get a dialog box that shows the running sql code but the dialog box isn't expandable
THerefore I am wondering if there is a storec provedure or if someone has a script, to see what the complete text of sql is for a running proess? Any shareware tools?
Any information that you can provide will be appreciated. Thanks.

I have a question that has a co-worker and myself confused. We are using the SQL Server Enterprise Manager. When I select return all rows in my tables, any content that is too long will appear as <Long Text> on my co-workers machine, but the column is blank on my machine. Is there a property or configuration that enables/disables <Long Text>? I am confused as to why it appears on other machines, but not mine.
Your help is appreciated.
Live Life.

I am having a problem while converting datetime to varchar with code 106. Here is the code and result I get:
TSQL Code:
SELECT CONVERT(VARCHAR(100), GETDATE(), 106)
Result:
"26 10 2007"
My expected result:
"26 Oct 2007" or "26 October 2007"
Have you encountered this problem before? Is it related to the SQL server setting? Please help and thank you in advance.

Hello-
i have a fairly big SQL query that is used to display data into a datagrid. Each query grabs data from two seperate databases. Is there anyway to combine these queries into one so all the data appears in 1 datagrid and not 2.
here is the 1st query:
SQL = "SELECT sum(case when month(pb_report_shippers.shipper_date_time) = 1 then pb_report_shippers_lots.quantity else 0 end) as Jan ,sum(case when month(pb_report_shippers.shipper_date_time) = 2 then pb_report_shippers_lots.quantity else 0 end) as Feb ,sum(case when month(pb_report_shippers.shipper_date_time) = 3 then pb_report_shippers_lots.quantity else 0 end) as Mar ,sum(case when month(pb_report_shippers.shipper_date_time) = 4 then pb_report_shippers_lots.quantity else 0 end) as Apr ,sum(case when month(pb_report_shippers.shipper_date_time) = 5 then pb_report_shippers_lots.quantity else 0 end) as May ,sum(case when month(pb_report_shippers.shipper_date_time) = 6 then pb_report_shippers_lots.quantity else 0 end) as Jun ,sum(case when month(pb_report_shippers.shipper_date_time) = 7 then pb_report_shippers_lots.quantity else 0 end) as Jul ,sum(case when month(pb_report_shippers.shipper_date_time) = 8 then pb_report_shippers_lots.quantity else 0 end) as Aug ,sum(case when month(pb_report_shippers.shipper_date_time) = 9 then pb_report_shippers_lots.quantity else 0 end) as Sept ,sum(case when month(pb_report_shippers.shipper_date_time) = 10 then pb_report_shippers_lots.quantity else 0 end) as Oct ,sum(case when month(pb_report_shippers.shipper_date_time) = 11 then pb_report_shippers_lots.quantity else 0 end) as Nov ,sum(case when month(pb_report_shippers.shipper_date_time) = 12 then pb_report_shippers_lots.quantity else 0 end) as Dec FROM pb_customers INNER JOIN pb_jobs ON pb_customers.customer_id = pb_jobs.customer_id INNER JOIN pb_recipes_sub_recipes ON pb_jobs.recipe_id = pb_recipes_sub_recipes.recipe_id INNER JOIN pb_jobs_lots ON pb_jobs.job_id = pb_jobs_lots.job_id INNER JOIN pb_sub_recipes ON pb_recipes_sub_recipes.sub_recipe_id = pb_sub_recipes.sub_recipe_id INNER JOIN pb_report_shippers_lots ON pb_jobs_lots.intrack_lot_id = pb_report_shippers_lots.intrack_lot_id INNER JOIN pb_report_shippers ON pb_report_shippers_lots.job_id = pb_report_shippers.job_id AND pb_report_shippers_lots.shipper_id = pb_report_shippers.shipper_id WHERE pb_customers.customer_deleted <> 1 AND pb_jobs.job_deleted <> 1 AND pb_jobs_lots.lot_deleted <> 1 AND pb_report_shippers.shipper_date_time between cast('01/01/2003 00:01AM' as datetime) and cast('12/31/2003 23:59PM' as datetime)"
Here is the 2nd query:
SQL = "SELECT ISNULL(sum(case when month(nonconformance.nc_date) = 1 then nonconformance.nc_wafer_qty else 0 end),0) as Jan , ISNULL(sum(case when month(nonconformance.nc_date) = 2 then nonconformance.nc_wafer_qty else 0 end),0) as Feb ,ISNULL(sum(case when month(nonconformance.nc_date) = 3 then nonconformance.nc_wafer_qty else 0 end),0) as Mar ,ISNULL(sum(case when month(nonconformance.nc_date) = 4 then nonconformance.nc_wafer_qty else 0 end),0) as Apr , ISNULL(sum(case when month(nonconformance.nc_date) = 5 then nonconformance.nc_wafer_qty else 0 end),0) as May ,ISNULL(sum(case when month(nonconformance.nc_date) = 6 then nonconformance.nc_wafer_qty else 0 end),0) as Jun ,ISNULL(sum(case when month(nonconformance.nc_date) = 7 then nonconformance.nc_wafer_qty else 0 end),0) as Jul ,ISNULL(sum(case when month(nonconformance.nc_date) = 8 then nonconformance.nc_wafer_qty else 0 end),0) as Aug ,ISNULL(sum(case when month(nonconformance.nc_date) = 9 then nonconformance.nc_wafer_qty else 0 end),0) as Sept ,ISNULL(sum(case when month(nonconformance.nc_date) = 10 then nonconformance.nc_wafer_qty else 0 end),0) as Oct ,ISNULL(sum(case when month(nonconformance.nc_date) = 11 then nonconformance.nc_wafer_qty else 0 end),0) as Nov ,ISNULL(sum(case when month(nonconformance.nc_date) = 12 then nonconformance.nc_wafer_qty else 0 end),0) as Dec FROM nonconformance INNER JOIN nc_department on nonconformance.department_id = nc_department.department_id INNER JOIN nc_major_category ON nonconformance.major_category_id = nc_major_category.major_category_id AND nonconformance.status_id <> '5' WHERE nc_department.scrap_category = '1' AND nonconformance.nc_date between cast('01/01/2004 00:01AM' as datetime) and cast('12/31/2004 23:59PM' as datetime)"
I know there has to be someway to combine these into 1. The issue I have is they are in different databases.
ANY HELP would be appreciated.

Hi everyone.... I'm trying to execute this update statement... It takes an eternity... any ideas on how to rewrite or speed it up?
It's a several step process... below is everything that i run, one step at a time. The final update statement is what takes so long. It should only affect about 2600 rows out of a potential 9000. That's why I'm confused on the response time
select d.olddevicename, de.device, d.newdevicename into #temp9
from dns d, devices de
where de.device = d.olddevicename
update #temp9 set device = newdevicename where olddevicename = device
update devices set device = #temp9.device from #temp9, devices where #temp9.device in
(select #temp9.device from #temp9, devices where #temp9.olddevicename = devices.device)
Thank you!
J.

Hi all,
I have 3 three scheduled job: one runs onece a day, one runs once per hour, and another runs every 17 minutes. It is a NetIQ application. I just scheduled SQL Server maintianace job last night which ran at 2:00Am and 4:00Am. This morning, I came in office and found all my jobs were still running; and they were all blocked by the first 3 jobs. I had to kill all of them. In this afternoon, I kicked off one of my many DTS packages which runs usually about 40 minutes, but it failed. I tried several times but no luck. I suspected one of user tables corrupted or one of stored procedures corrupted. After I recycle the server, and dropped the table and the stored procedure, and recreated them, the package went fine. The store procedure involves many updates and inserts.
The question I have is: is it possible to cause this problem because I killed the unfinished jobs (especially the sql maintanace job)?
NOTE: the sql maintanace job does not include the backup of database and transaction log.
