Slow Report From Simple Query

Apr 2, 2007

Hi all, I've been building a set of traffic based reports on our website and I've run into a strange problem.

The reports are pretty basic, and up till now I've been really impressed with RS overall.

Recently I've added a StartDate and EndDate and since then the performance has gone from ~10 secs to ~10 minutes.

I've taken a really simple query from my reports. Running this query in Management Studio on the same data returns in less than a second. When its run from a test report with nothing else in it it takes ~1 minute. Even stranger when I run the same query with the same values for parameters inside of RS in the data view it takes less than 1 second. ARG!


SELECT COUNT(DISTINCT SessionID) as Occurences
FROM WebAppSummary
JOIN WebAppLocalizations
ON WebAppSummary.ClientIp = WebAppLocalizations.ClientIp
where FirstTime BETWEEN @StartDate AND @EndDate


The last line that was just added is this part:
where FirstTime BETWEEN @StartDate AND @EndDate

So whats going on here? Is this a really poorly performing query that management studio is optimizing but RS isnt? Is RS messing up the databind and getting a bunch of DSs instead of just one?

Simple Insert Query VERY Slow !

Mar 7, 2005

Hello,

I don't know what to do anymore ;o(

I've got 2 servers, with sql server 2000 sp3 and ms windows 2003 server.
I've written a very simple stored procedure to insert 20,000 rows into a very simple table TEST (id int, msg varchar_50)

On the first server (P-IV 2 GHz), it takes 700 ms / 1000 insertions
and on the second (2x Xeon 2,6 GHz), it takes 13 s / 1000 insertions...

(insertion is : INSERT INTO TEST (id, msg) VALUES (@id, 'dummy text'))

...



SQL Server was installed exactly in the same way...

what could I do see where the problem is ? With profiler, I see no difference while logging all events....

please help or give ideas

Slow Performance With A Simple Query In A Small Table?

it take over 30s. Why it's slow? How can I check for reason? How to configure my server to improve performance?

Report Running Very Slow Compared To Query Analyzer - High TimeDataRetrieval

Jun 26, 2007

Hi,



I have a report in SQL Reporting Services 2005 which calls a stored proc and the report takes a very long time to run and sometimes returns zero records. But when i run the stored proc in query analyzer it takes about 4 seconds!!



I have checked the execution log on the RS using the below sql:






Code Snippet

use ReportServer

Select * from ExecutionLog with (nolock) order by TimeStart DESC



It shows that i have a large amount of time for the dataretrieval (601309ms, about 10mins) and does not return any records most likely because of a query timeout:



TimeDataRetrieval TimeProcessing TimeRendering Source Status ByteCount RowCount
601309 2227 3 1 rsSuccess 4916 0



The weird thing is that when i run it in query analyzer, i get about 400 records in 4 seconds !!



I dont understand what RS is doing to take up so much time like this to retrieve data.



The report is very simple - it basically returns the records straight out into a table.



The only thing I somewhat suspected was a parameter data type conflict between RS and SQL, specifically dates. I have a start and end date parameter in the report - i tried specifying this as date and string to see if it made any difference but it didn't.



Any help would be greatly appreciated.

Why Is A Simple WHERE Clause So Slow?

Jan 12, 2007

Dear Experts,I have a fairly simple query in which adding a where clause slowsthings down by at least a factor of 100. The following is the slowversion of the query-------------------------SELECT * FROM( Select x.event_date From x FULL OUTER JOIN yON x.event_date = y.event_date) innerQWHERE ( innerQ.event_date >= {ts '1980-01-01 00:00:00'} )------------------------Removing the where clause makes the query run quickly. This seemsextremely strange because it seems like SQL Server should simply beable to take the results of innerQ and discard anything with a datethat doesn't match. If I instead split the query into two pieces whereI create a temp table and put innerQ into that and then do the select *WHERE (...) from the temp table things work fine.Any thoughts on what SQL Server might be doing to make things slow andhow I can fix it?Thanks,-Emin

SQL Server Express Excruciatingly Slow With Simple Quries

Mar 10, 2008



I am running simple queries against test SQL Express installation and they take a very long time to return data. I have two SQL Express instances installed on colleagues' machines to which I connect for my testing and both exhibit the same problem. The setup is Windows XP SP 2 with 2 GB RAM and 3.6 GHz CPU. I am querying a table with around 7000 records and my query is simply SELECT TOP 1000 * FROM MyTable. It takes over 10 seconds to return the recordset!



I have done the research and found posts, which talk about AUTO_CLOSE option, indexes, query execution plan, etc. I have done everything those posts recommend, but performance is still terrible. All the instances have SQL 2005 SP2 applied.



I also found that the query runs fast locally on each SQL Express instance, the problem seem to happen when I am trying to pull the data over the network.



I am really not sure what else to look for.



Thank you,



Michael

Reporting Services :: SSRS Report Very Slow In Report Server?

Slow Report

Jan 18, 2007

As I sit here waiting for a test run of the report to complete, I'm forced to wonder why it's taking over 10 minutes... so far.

The query itself, when run through Management Studio takes about 50 seconds, so why would it take over 10 minutes to generate the report?  It's the only query being run, and it's not doing anything especially tricky with the data.  It's all actually being processed in the query, returning some counts and displaying them in a simple list.

Any thoughts?

EDIT:  I should mention that the query itself isn't very simple, so I can understand the query itself being slow... just not the report being 10 times slower than the query in management studio.

Slow Report Generation

Dec 14, 2005

I have developed several reports with selectable parameters.  When the report is first requested three stored procedures are triggered and return the parameters (+2 min), following parameters being returned the default report is returned (+3 min), this time is unacceptable.  Is there anything I can do to speed up the report generation?  Any help here is greatly appreciated.

Slow Initial Upload Of Report From .net

Jan 14, 2008

Hi,
In a .net application there is a link that brings up a SSRS report.
I have noticed that if it is the first time this report is requested i.e. Application has just been opened and the report button is clicked, then it takes a while to get this report to appear on the screen. But if this report is requested again (i.e. for the second time or more) then it only takes a few moments for the report to appear on the screen.
So it seems that only the first time the report is requested it takes a longer time to get this report. Is there a way to reduce this initial load of the report?
Thanks

SSRS Slow Waking Up On First Report

Jan 8, 2007



Greetings,

I continue to see this similar post all over the place, but no resolutions.

We have SSRS installed and operational in production. There are reports that get accessed from either an aspx page or from the built in IIS site for SSRS.

First time access is the performance problem. Here are two scenarios:

1) from your browser, pull up the front page to SSRS: http://myserver/reports. This simple operation will take about 2 minutes to come up. Drill to the report in question and it runs fairly well first time through. Throw a different query at it and it runs faster. If you wait a while (maybe 15 minutes +) the whole thing will spin back down and take 2 minutes to come up again. If you exit the website and come back immediately, everything still stays quick.

2) from an aspx page, same thing... if the service is spun down, the end user will typically get tired of waiting or timeout. Once everything is spun up, the process runs fine.

We setup another report that just does some simple statistics and added in a timed subscription for every 15 minutes hoping it would keep the service up and running.... no joy. Still the same.

Also adjusted the app pool to about every option to see if we could keep it running, but no joy.

====

So -- any ideas? Forget about running a report.... just think about pulling the website up. 2 minutes to get it to display in the browser the first time...

arghhhhhh

Thanks in advanced.

Initial Report Load Is Slow

Apr 14, 2008

Each day, the first user who launches our RS reports always gets a long wait time. Subsequent report launches are normal.
Does anyone know what is going on? If yes, what is the remedy?

Report Design Environment - Tool Is Slow!

Mar 5, 2008

Does anyone else have problems with the speed of the design environment for SSRS reports? We are using visual studio to create and manage hundreds of production reports (Oil and Gas).

It literally takes 5 seconds for the design environment to react to each change in the report layout. For instance, a common change is to reposition a text box, change the length, text, font size, font weight etc...:



Grab the text box - 5 seconds until designer responds - then reposition

Grab the edge to change the length - ditto

change text - 5 seconds for designer to "save" the change and allow next action....

blah - blah - blah....
So, performing the simple change above takes at least 30 seconds in addition to whatever time it took to edit the text box.

I've talked to the other developers using SSRS here and they all report that's "just the way it is".

Is this normal or is there an environment issue/setting we are overlooking.

Thanks, Mike

Charts Slow Report Rendering To A Crawl

Aug 23, 2006

I've searched the forums on this issue, haven't really found the answer.

I have several nifty little sales reports which crunch a ton of data quite efficiently and render in just a few seconds in Report Manager. I've pushed as much of the data processing back to the server as possible, use a stored procedure (with parameters) in a shared datasource, don't return unneccessary data, all that. It works great.

When I first developed the reports, I continued generating my charts (which use the same data as the reports, just grouped differently) in Excel and pasting them in as images. Now I want to stop that nonsense and use the SSRS charts. I fooled around with the charting function and got a reasonable facimile of my Excel charts, two per report, which use their own separate stored procedures and the same shared datasource.

Now, reports that used to render in 5-8 seconds may take 1-5 MINUTES. Help! It's definitely the charts--taking them back out fixes the problem.

I have complete control over the datasources--would it make more sense to use non-shared sources, or to create totally separate shared sources? I saw a post that recommended "making data calls non-synchronous," but I have no idea how to do that.

Thanks for any suggestions.

ASP.NET Report Viewer, Slow Rendering, Image Broken

Jan 29, 2008

Hi,

I have been using the report viewer to render my reports on a webpage. All worked fine for a time and now nothing is working correctly.

I have about ~8 report viewer on one page, all in an individual IFRAME. What happen is, sometimes I'm getting an error from IE (Internet Explorer cannot display the webpage) or the report starts loading (I see the title) but where the chart should be I have an X (broken image) icon.

Sometimes when I click on the image and choose "Display Image" the image will display.

Facts


Reports loads correctly on the report manager site (the Reporting Services webpage)
Once those errors starts appearing, the session seems to act funny and I can't even refresh the webpage (F5)
I have the latest report viewer patch installed
I have the SP2 for SQL Server 2005 installed
Running Windows 2000 Server
Running IIS 6
The website was developped using IIS 5, but was tested on IIS 6 for about 3 weeks and we started to have problems today.
The reports are linked with Analysis Services to get the data from cubes.
I'm really out of ideas right now. Maybe I should just restart the IIS server, but the thing is live and I can't do it right now. However, if I need to restart it, will the problem occurs another time? Will it become a solution to restart the server?

I already restarted Reporting Services and nothing has changed.

Thanks

Simple But Complex Report

Jul 20, 2005

Hi AllWondered if you could help.Basically I have 2 tables that contain all the data I want for my report,but I need to put it in a particular way and I need to display it in an ASPpage so my queries got to be manual rather than an MS Excel/Query 'munge'.To be honest, the report itself is very basic, so hopefully my ramble willmake sense. I need to report that shows 6 columns at best, 4 columns ifit's easier. Report looks like the following:Account Code - standard text fieldAccount Name - standard text fieldTurnover (Year to Date) 2002 - standard decimal number (single??) fieldTurnover (Year to Date) 2003 - standard decimal number (single??) field(not vital, but would be nice)Deviation as a straight figure between what the 2003 turnover figure isagainst the 2002 figure - ad hoc calc fieldDeviation as a % between what the 2003 turnover figure is against the 2002figure - ad hoc calc fieldMy table structure is as follows:TABLE 1 - ACCOUNTSThis contains all of the account codes (PK) and names as ACCOUNTID and NAMErespectively. It also contains a field called LEDGER which I would need touse in a Where clause to set this to 1 (1 = sales and 2 = purchases).TABLE 2 - ACCOUNTBUDGETSThis contains the Turnover details and is linked to the ACCOUNTS table by anACCOUNTID (FK??). This table contains a TURNOVER field for the actualturnover amount, a PERIOD field for the months of a year (eg, 1 - 12 - thatbeing Jan to Dec) and a YEAR field for the relevant years.In this ACCOUNTBUDGETS table it basically keeps a line-by-line record ofeach turnover for each period and year for each account code. As youprobably would with any transaction line storing table.An important part of this is that I want to show all of the Account codesand names that relate to LEDGER=1 even if they have no entries in theACCOUNTSBUDGETS table. The reason being is that I want to be able to showthat an account might not have traded for 2002 and therefore their 2003 Yearto date might be really good cos they've sold loads in 2003.So the final part is that I need summarise the Year to date figures next toeach account code and name. To do this I need to take what the month numberis now (eg, Dec = 12) and summarise all the turnover figures for 2002 upto12 and then all the turnover figures for 2003 upto 12. If you can imaginewhen this report is run in March the report would summarize from 1 to 3rather than 1 - 12 in the last examples.The nice bits on the end would be that they would give 2 different calcsagainst what the 2 turnover figures stated.The result should be something like the following:December Turnover YTDDeviationAcc No: Account Name 2003 2002 £%A001 Alpha Motor 9,250 5,398 3,85271%A003 A J V Secure 094 -1,294 -100%A004 Aye Gee 039 -4,239 -100%A007 P H Allin 2,23508 -1,973 -47%Any ideas??RgdsRobbie

Simple Report, Major Problem

Apr 13, 2008



I have a report with a table and three columns. Whenever the data in one of the columns cannot fit on a single page it continues on the next page BUT, there is no header on the next page and the data in the other two columns repeats itself on the next page. (This behavior happens when I export to PDF)


Is this a known issue? I have tried every setting I could think of.

Now when designing this report I cannot seem to access the related discount records for the line item. (as more than one can be applied) Every time I try to drag an field from one of the tables in the dataset to my report it automatically adds "First()" onto the field value expression. This seems to work fine for the order header, but doen't even come close to getting the right discount on the line item? I basically need to pass through the Line Discount table to get to the discount name field to put on the same line as my line item data on the report.



I have looked and googled for for an example on this, but have come up short. Can anyone point me in the right direction?



Thanks,



Chris

VERY Slow SQL Query

Mar 8, 2007

This sounds like a pretty easy one.  I have a SQL 2000 database with 2-3.4GHZ CPUs and 1GB of RAM.  I have one database on it.  I go in Query Analyzer on another machine and run a simple query like 'SELECT * FROM USERS'  which should return 15,000 rows. 
 
IT takes 30 (thirty) seconds to finish this query.  OMG
 
Where do I start to decipher why on Earth this takes more than .01 seconds?
 
Thanks.

A Very Slow Query

Oct 12, 2000

Hi,

I have a query that takes minutes to execute, even through there are about 300,000 records are being processed. I would appreciate any help with optimizing that query.
I have two tables: User and Usage. Table user has two fields: User_Id and Date_Created and a non-clustered index on User_Id. Table usage has two fields also: User_Id and Date_Used and non-clustered index on both fields. The User table is populated when the user registers. The Usage table is populated every time the user opens a document.

Here is what I need to do: get the number of users from the Usage table who opened a document at least once after they have registered during the last 30 days for each day in the time frame, where the time frame varies.
For example, if the time frame is 8/01/00 - 8/31/00, I need to get the following data:

date returns
---- -------
8/01/00 10 (10 users returned to the document between 7/2/00 and 8/1/00)
8/02/00 15 (15 users returned between 7/3/00 and 8/02/00)
.
.
.
8/31/00 20 (20 users returned between 8/1/00 and 8/31/00)

Here is my query:

SELECT [date],
(SELECT count(distinct user_id)
FROM usage u JOIN [user] ON u.[user_id] = [user].[user_id]
WHERE u.[date] BETWEEN usage.[date]-30 AND usage.[date]
AND u.[date]>[user].date_created
GROUP BY usage.[date])returns
FROM usage
WHERE [date] BETWEEN @date1 AND @date2

This query works fine, but too slow. We use MS SQL server 7.0.

Thank you,
Yana

Slow Query

Dec 2, 2002

I have a query which responds immediately when run however if I add an order by clause it takes 40 seconds. Below is the query with the order by clause
SELECT distinct Licenseplate, platetypecode.platetypecode, platetypecode.platetypecodeid
FROM Ticket INNER JOIN PlateTypeCode
ON PlateTypeCode.PlateTypeCodeID = Ticket.PlateTypeCodeID
ORDER BY licenseplate

The Ticket table contains approx. 11,000 records. I have created a nonclustered index for the licenseplate field, a 7 char varchar field.
Any suggestions for speeding up the query?

Oh So Slow Query...

Jun 15, 2004

The following query is causing some problems because it's taking too long to complete. I looked at the estimated execturion plan and I am unsure why it appears to spend over 50% of its time doing a 'Bookmark Lookup' on on particular column (SRA_SR_ID in the S_EVT_ACT table). There is an index on the column - S_EVT_F14. I'm not sure if the query is using the index properly. What can be done to specifically improve this particular problem? In general, does anyone have some suggestions for optimizing the query as a whole?

Thanks in advance. Clive

Help Fix Slow Query.

Oct 12, 2006

I have a query that is taking too long to run. It take 14 seconds to return 6800 rows. However, if I move the query out of a stored proc, it takes 1 second. I want to understand this issue and ideally fix the stored proc case.

I've simplified my actual queries for readability.


-- @filter is value to filter against or NULL to return all records.
CREATE PROCEDURE queryPlayerStations(@filter INTEGER)
AS
SELECT * FROM MyTable
-- Other joins and query logic omitted for brevity
WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))
GO

DECLARE @filter INTEGER
SET @filter = NULL

-- Takes 14 seconds to return 6800 rows. That's unacceptable performance
EXEC dbo.queryPlayerStations @filter


When I run the query directly in Query Analyzer, it runs very fast.


DECLARE @filter INTEGER
SET @filter = NULL

-- Takes ~1 second to return 6800 rows. That's great performance
SELECT * FROM MyTable
-- Other joins and query logic omitted for brevity
WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))


When I put the parameters in the stored proc it runs fast.


CREATE PROCEDURE queryPlayerStations
AS
DECLARE @filter INTEGER
SET @filter = NULL

SELECT * FROM MyTable
-- Other joins and query logic omitted for brevity
WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))
GO

-- Takes ~1 second to return 6800 rows. That's great performance
EXEC dbo.queryPlayerStations


Anyone have any ideas what I can do to improve the stored proc case?

Very Very Slow Query

Mar 27, 2008

Hi guys/gals

I have only just signed up, as I have a problem thats confusing me a lot

I have a page (classic asp - sadly) that displays a list of invoices for a certain customer

Each of these customers has fairly complex permissions system, but the page generates a list of invoices and values in 0.01 seconds

However in the while...do loop, for each invoice it checks a database table for "extra charges"..

This is a simple SQL query

"Select Sum(amount) from extra_charges where invoice_number=" & current_invoice_number

However each time it runs this simple select statement it takes 2 seconds - which causes the page to load in 70 seconds instead of 0.01

I am absolutely beyond confused. I have tried it in a stored procedure, and a direct ado query..

The table by the way is empty on my current test system, and one one other system has about 150 records in it. Both take the same time

Any help would be appreciated?

This is a MSSQL 2000 database I've inherited, I am usually a PHP/MYSQL developer - so im a little out of my field of expertise here

Slow Like Query

May 26, 2004

i want to have a like search in the following query.

SELECT DISTINCT TOP 200 a.AccountID,
a.AccountNumber,
c.CLI,
con.SurName,
addr.Address1 [Account Address],
addr.Postcode as [Account Postcode],
atp.Name AS Type,
cs.Code AS Status
FROM account_t a
INNER JOIN customer_t cust on a.customerID = cust.CustomerID
INNER JOIN AccountType_T atp on cust.AccountTypeID = atp.AccountTypeID
INNER JOIN CustomerStatus_T cs ON a.CustomerStatusID = cs.CustomerStatusID
INNER JOIN Contacts_T con on cust.MasterContactID = con.ContactID
INNER JOIN Address_T addr ON cust.MasterAddressID = addr.AddressID
LEFT OUTER JOINCLI_T c ON a.AccountID = c.AccountID
WHERE (c.CLI LIKE @CLI + '%')
AND (con.SurName LIKE @Surname + '%')
AND (addr.Address1 LIKE @Address + '%')
AND (REPLACE(addr.Postcode, ' ', '') LIKE @Postcode + '%')
AND c.DateArchived IS NULL

here all fields @CLI, @Surname, @Address, @Postcode are varhcar types...which is making this query very slow...is there any suggestion to improve this query?

thanks in advance
bhavya
