I have a stored procedure which creates 3 temporary tables. Every table is about ten rows and 25 columns. The inserts in the tables goes fast (< 30 ms). The selects from them is also that fast. BUT the first select takes about 3200 ms one each of the temptables. (I first do insert, then select from them.) So the SP executes at about 13 seconds instead of 3.
Any suggestions, anyone, please?
I've noticed that after the database have been idle for some time, it takes up to 10 seconds to get it started when something needs to access it. In the event viewer it says that the database <name> have been started.
Obviously, there is some idle timeout setting.
I saw an option in the database properties that is called "Auto Close" which is set to true. I assume this is what i'm looking for. Can someone confirm that? (it could take some time to test myself...)
But what i'm actually wondering is:
1. Is it possible to adjust how long it would wait before timing out?
2. What advantages does closing the database bring? Does it free up (a noticeable amount of) ressources? Or is it only that it's unlocking the files, so that it's possible to copy the database source files?
Hi!
I have several problems of my coding, please give me some advice.
1. How to let result data place at temptable temperary for other mapping? should i create temptable first ?
2. When I got the duplicated record result, I require to map with the main tables (tblROrder & tblSOrder)to find out the record reference no. Please advice how to handle this issue with reference no. at the outcome.
Many thanks,
New Learner
***Coding as following
SELECT code, SMSNo, holderNo, count(*) From tblROrder
WHERE Day = @Day
GROUP BY code, SMSNo, SholderNo
HAVING COUNT(*) > 1<=====result will be found, but since i didn't get the RefNo at the listing, please advise how to let the outcome with RefNo
INTO #tmpOne (code, SMSNo, holderNo) <====error found
SELECT code, SMSNo, holderNo, GrossAmt, count(*) From tblSOrder

We have an application that has about 100 users at a time. Roughly once a day, we experience a complete
slowdown on the server. All users notice it. The network seems fine because I can ping the server. Also,
I can attach to drives on the server quite fast so I don`t think it`s server resources. When I manage to
get in and do an sp_who, certain processes are blocking others. Talking to the users who were blocking,
they were not doing anything out of the ordinary - one was even doing just a select. The error log is full
of 17824 and 1608 errors. Is there some configuration setting that I should change? This is getting serious!
Thank you.
Hi, I have a query which returns normally in less than a couple of seconds. When coupled with a "TOP" statement however, the execution time changes in a way I can't explain.
When using "TOP 1000", the query returns in its normal time. Any top value greater than 10 seems to function normally. However, as soon as we hit this "magic number" the query begins taking 30+ seconds to return.
As far as we can see, there is nothing odd about this query or the data that it is searching, and this problem has us stumped! Can anyone explain why top is producing these results, and is there any optomisation changes that anyone can suggest to give us faster queries in these cases?
Many thanks, Andy J.
Hi
i had a problem with the SSIS response time - its very slow.
When I try to open the solution and than click to open the Pakage it's take at least 6-10 minutes until it's open.
Please advice what can be the reason
10x
Using SSMS 2012, we are experiencing extremely slow response times when opening SQL job steps to edit and also deploying SSIS Pkg's. Sysadmins have no problem. Users in the ssis_admin role have no problem. It's the rest of the users who have issues.
View 1 Replies View RelatedThe following question might sound a bit stupid but I'm not a database expert so hopefully nobody minds me asking it.
Here's what I did:
1. I created an SSIS package that is supposed to import new data into my data warehouse as it becomes available.
2. Since I need to maintain some of the history I use the Slow Moving Dimensions part (set the history flag on input fields) but run into an error condition while running the package. The message basically says that I'm about to create a duplicate record which is not allowed.
Original Table1:
PK1 field1
PK2 field2
PK3 field3
field4
field5
-----------
Now I enhanced it like this:
Extended Table1:
PK1 field1
PK2 field2
PK3 field3
field4
field5
CreateDate (new)
NewDate (new)
ActiveFlag (new)
_____________________
Now on some records the package is supposed to archive history by populating the (new) fields. In order to keep the record unique (primary key constraint) thought, do I need to make the (new) fields primary keys as well?
So I guess I'm struggling with a more basic concept;)
I would appreciate if somebody could shed some light on this.
Thanks in advance.

The SSRS website is slow when accessing it the first time after a period of inactivity (30 min. or longer). What could be causing this and how can I make it fast all the time.
View 1 Replies View RelatedHi,
I have a problem with querying systemjobhistory data. Response time is slow and it is vary from time to time, sometime it takes few seconds and sometime it takes more than 2 minutes. I understand that there is quite a number of jobs in DB server and which might result in slow response time.
Is it possible to shorten the response time? like using index? My application is always look like hang when the query take very long time to run.
Any help is greatly appreciated. Thank you.

I am running SQL 2005 reporting services on a windows 2003 machine with SharePoint over SSL
My reporting services web directories are virtual directories under the SharePoint website.
I am having a problem with loading https://sharepoint.mysite.com/Reports/Pages/Folder.aspx
When you first open IE and bring up the page it takes about 30 seconds to load. Once you have connected via any machine, all other machines can connect at normal speed 1-2 seconds. All testing is being done on our LAN so there is no bandwidth issues when opening the pages.
My guess is that something is going into a sleep mode, but I am not sure where that would be set.
Thanks for any suggestions

Hello All,
I’m looking for a solution to timeouts that occur when I’m executing a stored procedure from my web application. Most of the SPs will run from 3 to 15 minutes, and, unfortunately, modifying/optimizing them isn’t an option at the moment. I tried setting the CommandTimeout to 0 with no luck. Unless, I didn’t use it properly. Here’s my code: 1
2 try
3 {
4 string dbConn = ConfigurationManager.ConnectionStrings["ConStringNTMTLDEV"].ToString();
5 OleDbConnection connection = new OleDbConnection(dbConn);
6
7 lbl_SearchResult.Text = dbConn;
8
9 //OleDbDataAdapter adapter = new OleDbDataAdapter();
10 OleDbCommand cmd = new OleDbCommand("SP_CallHistoryLookUp", connection);
11 cmd.CommandType = CommandType.StoredProcedure;
12
13 cmd.Parameters.Add(new OleDbParameter("@phoneNumber", "1234567890"));
14 cmd.Parameters.Add(new OleDbParameter("@email", "123@123.com"));
15 cmd.Parameters.Add(new OleDbParameter("@WebUser", "123"));
16 connection.Open();

I have 25+ WinXP SP2 workstations on a Novell file server (Novell login) and also have a W2K SQL 2000 Server for our database. We are usint Win NT authentication to the SQL Server.
One AND ONLY ONE user is having trouble with this setup. Her workstation is PAINFULLY slow accessing the SQL server through my Delphi programs, through our third party programs, and through ODBC connections.
I thought it was her workstation until I configured a clean workstation for her, and it too had the same problem. I then took a brand new Dell 9200 workstation with 2gb memory, gigabit NIC, etc. and configured it to use our servers. It too had the same slowness connecting to the SQL server. Everything else is fast.
I deleted her entry in the NT domain users table, and re-entered her. No help.
Can anyone shed any light on this?
Hii,
A bit new to SQL 2k5 but here goes, I recently installed SQL 2k5 on a preety decent box with about 4GB Ram and created a database called PointOfSale. As probably obvious by now, the application that accesses the Database is a PointOfSale application.
The store sells ladies clothing items, of which each is barcoded.
When an item is scanned via the barcode reader into the application, it takes like about 10-15 seconds for the item information to appear. Of course the item information resides on the database.
There are three registers and the same thing happens on all. I am running sp 2 for sql2k5 already.
Any thing I can do that would reduce the 15 sec delay significantly?
Any help at all would be appreciated immensley.

Burt.

Hi,
I have migrated my app from VB to VB.Net. A 3-tier app with remoting and COM+.
I am experiencing a long wait time of about 3 times higher than what it would take in the VB App.
I am using DataAdapter.FiLL method to fill the datatable.
I have tried.
Using DataReader ( Made the things worse )
Using BeginLoadData and EndLoadData
Creating a Dataset and calling fill with the dataset so that the round trip to the middletier is saved to bring the SQL.
But i feel now that whatever is done. the problem is with the fill method only?
Is there any alternative?
Please suggest. It is one of the most important thing which if not possible may lead to scrapping up idea of upgrading to .Net.

We have an issue with accessing SQL Server 2000 where the access of data from the database is slow unless the user is logged in as an administrator to their computer.
The system is as follows: SQL Server 2000 on a W2K server. Users logging into a Win 2003 domain server. Users using W2K on their workstations. Application is VB.NET using the Enterprise Library Data Block, connection pooling ON, and windows authentication.
We are assuming that the issue is down to one of authentication and that when a user is set as an administrator then they have instant access. We have been able to replicate the issue using just SQL server on a W2K workstation and accessing from another W2K workstation. Again data access is way slow unless the account is an administrator.
Glad of any ideas folks!

The same transaction is now taking 8 to 9 minutes.
I tracked it down to this particular table. Just doing a count(*) takes over 5 minutes. Select * where ID = 1 takes over 5 mins. Also, whenever the table is accessed you can hear the server thrashing the disks. Other tables, although smaller do not seem to be suffering from this masive performance drop..

Hi
Here is the brief to my problemWe had our database on SQL Server 2000 and Windows 2000.This machine
had 2gb of RAM and dual Penitum 3 processors and about 25-30 users were
connected all the time. The size of database is around 2 gb. Even on this setup
rate of data retrival was good, never had any issues. We moved to SQL Server 2005 and Windows 2003. This machines has
2 Pentium Xeon 3.4 processors and 2 stick of KINGSTON 1024 MB 333
MHZ DDR DIMM ECC CL2.5 DUAL RANK X4 INTEL. The rate of data
retrival is awful and its very slow. It using about 1.7 to 1.9 gb of RAM all the
time. Page File usage is about 2.07 gb and Virtual Usage is about 1.7gb.I dont quiet understand why is it so slow to get data. We use bespoke software,
so nothing has changed there. Hardware specification of our server is far more better then the recommended
system requirement for SQL Server 2005.Am i missing something out or i havent set up the SQL Server properly? Any help would really be appreciated.Mits
I have an Access2000 ADP that I want to run under Access2007. The problem I have is that some forms take up to 45 seconds to open in Access2007! These are not complicated forms--just simple navigable reference forms like setting up transaction types etc. that are based on basic select statements like:
SELECT * FROM ArReceivableType
Where ArReceivableType is a reference table (less than 10 columns, all int or nvarchar(100) max) containing about 15 or 20 rows. They open instantly in Access2000.
I put a trace on to see what is happening on the SQL Server, and I noticed heaps of nasty code like this that generates tens of thousands of reads:
select object_name(sotblfk.id), user_name(sotblfk.uid), object_name(sotblrk.id), user_name(sotblrk.uid) from sysreferences srfk, sysobjects sofk, sysobjects sotblfk, sysobjects sotblrk where srfk.constid = sofk.id and srfk.fkeyid = sotblfk.id and srfk.rkeyid = sotblrk.id and user_name(sofk.uid) = N'dbo' and object_name(sofk.id) = N'FK_FaAssetTransactionWork_ArReceivableType_ArReceivableTypeId'
It looks like Access2007 is reading all of the constraints for the underlying table, including all foreign keys. My SQL database contains 1400+ tables all with properly constructed foreign keys and other constraints.
Any suggestion on how to NOT have Access2007 do this? Right now, Access2000 works great for this enterprise app, but I really like the new Access2007 features (and I don't want to still be developing Access2000 apps in 2010).
Hi,
first time poster/newbie here.
I've
got a football (soccer for the yanks!) predictions league website that
is driven by and Access database. It basically calculates points
scored for a user getting certain predictions correct. This is the URL:
http://www.pool-predictions.co.uk/home/index.asp
There
are two sections of the site however that have almost ground to halt
now that more users have registered throught the season. The players
section and league table section have gone progressively slower to load
throughout the year and almost taking 2 minutes to load.
http://www.pool-predictions.co.uk/home/players.asp?tab=a_d
http://www.pool-predictions.co.uk/home/table.asp
All
the calculations are performed in the Access database Ive written and
there are Access SQL queries to get the data out.
My
question is, is how can I speed the bloody thing up! ! Somone has
alos suggested to me that I use stored procedures and SQL Server to
speed things up? Ive never used SQL Server before so I am bit scared
about using it (Im only a hobbyist), and I dont even know what a SP is
or does. How easy will it be upgrading the whole thing to SQL Server
and will it be worth the hassle, bearing in mind I expect my userbase
to keep growing? Do SP help speed things up significantly? Would
appreciate some advice!
Thanks in advance,
John.
One of our developers has a Microsoft Access 2000 database that runs queries that compare the Access db data to a SQL Server database. He uses pass through queries to get the data from SQL Server.
We're finding that the Access query runs quickly against our test server, even with copies of production data, but when we try the same query against our production server, the CPU on the local computer running Access is pegged and the query takes up to 10 minutes to run.
First I verified that the SQL Server structures between test and production were identical, including indexes. I checked index fragmentation, and productions indexes are less fragmented than tests. Again, test and production currently have the identical data.
I've run a profiler trace on our production SQL Server 2000 server, and I see the RPC for the query from Access running almost instantaneously.
Any ideas on what might be the cause of the difference in speed between test and production SQL Server servers, or any suggestions on other things I could look at/tools I could use to troubleshoot this issue further?
