2 Identically Databases - 1 Is Fast And 1 Is Slow
Jul 29, 2005
Hi!
we've got a curious problem. we've two identicall databases, same tables, same date, same indexes, same server, both replicated.
One of them is our life database and the other is our development database. If I execute the following query at the development database the query takes less then one second. If I execute the same query at the live database the query takes about 4 seconds to complete. This is very unsatisfactory!!
What I've noticed is, if I try to analyze the query in the tuning advisor on the developement database it completes without tuning tips. If I do the same on the live database I get the following error:

I have a very puzzling situation with a database. It's an Access 2000 mdbwith a SQL 7 back end, with forms bound using ODBC linked tables. At ourremote location (accessed via a T1 line) the time it took to go to a recordwas very slow. The go to mechanism was a box that the user typed the indexvalue into a combo box, with very simple code attached:with me.RecordsetClone.FindFirst "[Index] = " & me.cboGoToIf Not .NoMatch ThenMe.Bookmark = .BookmarkEnd Ifend withNow, one would say that going to a record is slow because I'm using..FindFirst over a T1 line. And that's what I thought. However, as I wasworking with the form, commenting out various sections not related to the GoTo, I found that the Go To functionality changed, though I didn't modify thecode.Previously, going to a record near the end of the 50,000 record recordsettook about 1-2 seconds, but going to a record near the beginning, took about20 seconds. After the form changed, going to any record in the recordsettook about 1-2 seconds.So the question remains: why did it take so long to go to a record near thebeginning of the recordset, but not near the end (and the ones in the middletook an amount of time about halfway between the two), and what changed sothat now the form is working fine for all records?I've compared the changed form with the previous copy, and I don't see anydifferences. I've compared all code in the form module, and I've comparedall form properties. The forms are identical as far as I could tell. Butsomething happened as I was commenting/uncommenting code in the form thatgot rid of the problem with it taking a long time to go to some of therecords.My first thought was that something got recompiled, and now the form isfast. So I went back to the original version and changed some code andrecompiled, also did a compact and repair. But it was still slow. I alsotried doing an explicit decompile and then recompiled it. But it was stillslow.So this is very frustrating that the form is now working fine, but I can'tsee anything that's changed. If I don't see why the form is now fast, thenthere's no reason to believe that it might not at some point go back tobeing slow again. And then I'd just have to hope that something changes. Itwould be good to figure this out.Any ideas as to what might have changed here to cause the form's Go To to befast would be appreciated.Thanks,Neil

I have created an integration services package with a script-source reading data from Active directory. Pretty much data is read and written into a sql2005 database.
I have notised that when I run the package via right-clicking the package (Under stored packagesMSDB) and selecting "Run Package" it takes about 45 minutes for it to complete successfully. The same goes if I run the package from inside Visual Studio. However, when I create a job and put this package as one of it's tasks the task takes about 1h 40min. This is more then double the time! In neither case the server is occupied with soething else. And I have tried it several times so it wasn't just an "accident".
Any idéa of what this depends on?

I'm trying to figure out how to determine why the same database is fast on my desktop but slow on a robust multiprocessor win2003 server.
I have a complex proc that takes about 27 seconds on my desktop sql server but takes almost 5 minutes on the server. The server processors are running at about 1% utilization while the proc is running.
Any ideas on how to troubleshoot this extremely poor performance?

Hi,
I have a query that takes 15minutes to run the first time after sql server start but then for subsequent querys is superfast (less than 10 secs).
Why? What could I do to speed up the first run?

I have a very unusual situation - we converted a client from DB2 7.2 to MS SQL Server 2000, SP3. There is one report that runs very quickly when ran on the Database Server, but it takes a long time to complete when it is ran from a client system. This query is ran from within the application and not from within Query Analyzer.
Has anyone else here ever encountered this issue? What did it turn out to be? I am leaning away from it being a network issue.
Thanks in advance.

In an ASP, I have a dynamically created SQL statement that amounts to "SELECT * FROM Server1.myDB.dbo.myTable WHERE Col1 = 1" (Col1 is the table's primary key). It returns the data immediately when executed.
However, when the same record is updated with "UPDATE Server1.myDB.dbo.myTable SET Comments = 'blah blah blah' WHERE Col1 = 1", the page times out before the query can complete.
I watched the program in Profiler, and I saw on the update that sp_cursorfetch was being executed as an RPC once per each row in the table. In a table of 78000 records, the timeout occurs well before the last record is fetched, and the update bombs.
I can run the same statements in Query Analyzer from a linked server and have the same results. The execution plan shows that a Remote Query is occurring on the select that returns 1 row, and a Remote Scan is taking place on the update scanning 78000 rows (I guess this is where all the sp_cursorfetch calls are happening...?).
How can I prevent the Remote Scan? How can I prevent the execution of the RPC sp_cursorfetch for each row in the remote table?
Thank you!

We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?
Here is the class:
Code Snippet
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";
HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));
request.Timeout = 1000;
HttpWebResponse response = (HttpWebResponse)(request.GetResponse());
StreamReader streamReader = new StreamReader(response.GetResponseStream());
returnQuote = streamReader.ReadToEnd();
streamReader.Close();
response.Close();
return returnQuote;
}
}
}
When I run call it from a console app it is fine.
I compile it into a dll and then create the assembly and function as follows:
Code Snippet
drop function fnTestGetIntradayQuoteXML_SJS
go
drop assembly TestGetIntradayQuoteXML_SJS
go
create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS
go
CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote
go
declare @testing nvarchar(max)
set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')
print @testing
When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?
Regards,
Skipper.

Performance issue.
I have a very complex Stored Procedure called by a Job that is Scheduled to run every night.
It's execution takes sometimes 1 or 2 hours and sometimes 7 hours or more.
So, if it is running for more than 4 hours I stop the Job and I run the procedure from a Query Window and it never takes more than 2 hours.
Can anyone help me identify the problem ? I want to run from the Job and not to worry about it.
Some more information:
- It is SQL 2000 Enterprise with SP4 in a Cluster (It happens the same way in any node).
- The SQL Server and SQL Agent services run using a Domain Account that have full Administrative access.
- When I connect to a Query Window I also use a Windows Account.
- There is no locks or process bloking or being blocked while the job is running.
- Using the Task Manager the processor activity is ok, no more than 30 % in any processor.

Hello,
(Using win2k, sqlserver2k, framework 1.1)
I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
Any ideas??

my system has 2 db's - sql server 2000 & db2 @ separate locations. i have a select query which needs 2 pick up consolidated data from both the tables. also the schema on the db2 has minor changes when compared with the schema on sql server 2000.
while searching on microsoft i came across the technique of creating a linked server. would this be possible 2 implement in my scenario. also would in this case, be advised that i create another view in the db2 server which has changed the db2 schema to the sql server schema format??
please hurry..

I have stoopidly enough deleted default Db. That causes Enterprise Manager to be unable to work with my DB's. The default DB I deleted had no other functions other then being default DB, I mean it was outdated, and I had other DB's that contained all my importent work. They are still running, and I can view DB driven site hosted at localhost, even though default DB no longer excist. I am even able to upload new content, or add new users, so this means all my other DB's are fine. I can even see SQL server icon in my bottom right corner of my desktop, and it shows server running.
Now I am in the need of adding tables and rework some of my excisting tables and stored procedures, but I am not able to do that with Enterprise Manager, due to the lack of default Database.
How do I correct this problem? I have gotten one tip of doing the following: EXEC sp_defaultdb 'User', 'DB' but I am not sure what to do with this.....tried to run it from command line, and put my username and the DB I would set to default but nothing happend.
So I need more details, step-by-step guiding will work, as I don't know a hole lot about Enterprise Manager and SQL.
Btw, this is my error in Enterpr.Managr:
A connection could not be established to MyComputerVSDOTNET2003
Reason: Cannot open default database. Login failed..
Please verify SQL server is running and check your SQL server registration prpoerties and try again
Pls tell me there is a way to fix this problem.

Hello everybody,
please advice: what is the fastest standard method of user interface access to SQL database? I am looking for fast display of one master record plus related dependent records, plus fast scrolling through master records with display of dependent records as fast as posible. Perhaps a standard problem with standard solution? At current state of matters, I am still much slower then with my old Access97 database.
thanks for any advice,

I notice this morning that my tempdb grows very fast. I have 26GB in my
hardrive and all the space occupied by tempdb and finaly the qeury got failed due to 0 space in hardrive and there is no space to grow tempdb.
The select query supposed to bring about 40000 rows.
I ran this same query in different server that is not growing even 1 mb.
I checked the tempdb option the Trunc log on checkpoint is true.
Why this problem happening ?.
I have just dbo permission to access all the database.
Do you have any advice regarding this?.
Thanks,
Ravi

Hello, everyone:
My database backup files are 3-5GB. Restoring always take over 20 minutes. Is there the fast way to restore the big database?
Thanks

(Win2003, SQL Server 2000 SP4)
I have a database of about 5Gb of size. Some queries where taking more than 1 minute to complete execution (all of them are stored procedures). Because of that lack of performance, I call the command DBREINDEX for each table, executed the sp_updatestats system stored procedure and finally I executed the sp_recompile system stored procedure for each sp in my database.
After all this task, queries completed in a matter of a few seconds instead of minutes. Strange enough is that some hours later (about 6 hrs), after normal use (this database belong to a Client/Server information system), the problem appeared again: Queries started to take too long to complete.
I am assuming that indexes are degrading too fast so that they required another ReIndex, but I am not sure.
Any thoughts? How can I prevent this behaviour?
Thank a lot in advanced.

I have a weird situation I had not expected.....
I insert a record to a table and "later" I update it.
I have two fields to capture time information: Created and LastModified.
My update is very simple: update .... set ..,[LastModifiedDate] = GetDate() where id = @pId.
Now my problem is that I am seeing the created and lastmodified times as the same (in format 2007-09-05 12:38:42.383) !!??!
The record has definitely been updated (other fields are populated).
Can anybody enlighten me?

Hi,
I have made some stored procedures to check if a user is involved with a certain record. basically every stored procedure contains the following logic.
example spCheckClientRelated:
select @res = count(*) from client_role where client_id = @cid and employee_id = @eid
if (@res = 0)
begin
... next select
end
if (@res = 0)
begin
... next select
end
....
return @res
end
so far so good. But the final check in CheckClientRelated tests if a user is related to one of the sales projects for that client.
I allready have the spCheckSalesProjectRelated that returns 1 or 0 similar to the example above
so I want to find an efficient method that selects all the sales_project_id 's from the sales_project table where client_id = @cid (i use offcourse select @sid = sales_project_id from sales_project where client_id = @cid at the moment)
And then I have to execute the spCheckSalesProjectRelated method for each @sid and @eid. This if offcourse where my problem is located. I don't know how to do a fast check for every selected @sid, until spCheckSalesProjectRelated returns 1
As you probably can determine from my question, sql is not really my domain, and I'm certainly not an expert, but I don't mind reading or looking up some stuff, so even a clue or a direction to look in would be most appreciated
thx in advance.

I have a table containing URLs. I want to be able to look up an URL veryfast, so I used an nvarchar to store the URL, and put an index on it(maybe naive).Anyway, I bump into:"The index entry of length 911 bytes for the index 'UQ__URL__1367E606'exceeds the maximum length of 900 bytes."What's the best way to handle this? I want to do the look up fast. Theonly thing I could think up was adding an extra column containing a digestfor the URL, and look up all URLs with the same digest, *and* having thesame value (which could give either 1 or 0 results).I am new to MS SQL, so I might describe a silly solution, basically I wantto look up URLs to ID the fastest way possible.--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html

I am trying to implement a very fast queue using SQL Server.The queue table will contain tens of millions of records.The problem I have is the more records completed, the the slower itgets. I don't want to remove data from the queue because I use thesame table to store results. The queue handles concurrent requests.The status field will contain the following values:0 = Waiting1 = Started2 = FinishedAny help would be greatly appreciated.Here is a simplified script to demonstrate what has been done.CREATE TABLE [dbo].[Queue] ([ID] [int] IDENTITY (1, 1) NOT NULL ,[JobID] [int] NOT NULL ,[Status] [tinyint] NOT NULL) ON [PRIMARY]GOCREATE INDEX [Status] ON [dbo].[Queue]([Status]) ON [PRIMARY]GOCREATE PROCEDURE dbo.NextItem@JobID integer,@ID integer outputASSELECT TOP 1 @ID = [ID]FROM Queue WITH (READPAST, XLOCK)WHERE (Status = 0) AND (JobID = @JobID)RETURNGO

I seem to remember reading many moons ago about a function where youcan retrieve a count of the last recordset you opened.For example:I've got a stored procedure that returns a recordset using the TOP 10so I only get the top 10 records. I need to know the recordcount but Idont want to reuse the SELECT statement because its quite complex.Any ideas?What does @@Count do?Thanks in advance

I think I am asking this in the right place.
I'm trying to get a record count from a table with 30million items and it takes forever.
Here is my code:
SELECT COUNT(f_id) AS 'ROWCOUNT' FROM tablename
Is there a faster way.
BTW f_id is primary key indexed.
Thanks
