I have a SQL Server 2000 with a dozen of databases. The databases are rather small (all sum up to 10 GB).
The entire server gets extremelly slow from time to time (lasting a few days when it happens and suddently coming back to normality). A profiler trace doesn't show anything strange (besides a lot of SQL Agent entries).
I pretty much tried to isolate every single application that makes use of the databases in that server and see if it was the cause of the problem, but I couldn't find any correlation.
I know the computer where this server runs is quite fragmented. Is there any way I could make sure this is the cause of my performance issues?
I don't know if this might help, but once the server simply went down for some 3 hours, and I wasn't able to bring it up in any way. It eventually started working again by itself. The only thing I did in the meantime was to run DBCC CHECKDB a few times, always getting the response "No errors found on the database".
I have a query slower in SQL Server 2005 than in SQL Server 2000. I have a database in SQL 2000, I put it on the same server, but with SQL 2005 and the query take 5 seconds instead of 0 seconds. The DB compatibility is SQL Server 2000 (I tried with 2005 and result is the same). Execution plan seems right and I tried to change some DB options without results. It is weird, when I remove left join on MandatsEx, it take 2 seconds. The view currentEmployeeLevelHistoric returns 45 000 rows and mandatsex has 0 rows.
Here is the sample:
Select ls.EmployeNiveau.pk_EmployeNiveauID as NoNiveau, IsNull(nullif(ls.Traduction.Description, ''), ls.TraductionDefaut.Description) + ' (' + ls.currentLevelHIstoric.NoNiveau + ')' As Nom, ls.currentEmployeeLevelHistoric.DebAssign As DateAssignationDebut, ls.EmployeNiveau.assignmentReason As AssignmentReason, ls.currentEmployeeLevelHistoric.FinAssign As DateAssignationFin, ls.MandatsEx.noDossier, ls.MandatsEx.pk_MandatID, '' As Period, ls.currentEmployeeLevelHistoric.NiveauPrincipal, ls.currentEmployeeLevelHistoric.pk_emplNiveauHisto_Id, ls.EmployeNiveau.fk_NiveauID_Niveaux, ls.EmployeNiveau.No_Ent_leg, IsNull(nullif(TradPere.Description, ''), TradDefautPere.Description) + ' (' + NiveauPere.NoNiveau + ')' As NomSup, ls.EmployeNiveau.No_Ent_leg + ls.EmployeNiveau.no_divisio + ls.EmployeNiveau.no_sec_eco + ls.EmployeNiveau.no_etabli + ls.EmployeNiveau.no_mat as employeeScope, case when ls.mandatExternalisation.fk_mandatID_MandatsEx is null then 2 else 1 end as ContractCategory From ls.currentEmployeeLevelHistoric Inner Join ls.EmployeNiveau on ls.currentEmployeeLevelHistoric.pk_EmployeNiveauID = ls.EmployeNiveau.pk_EmployeNiveauID Inner join ls.currentLevelHistoric On ls.EmployeNiveau.fk_NiveauID_Niveaux = ls.currentLevelHistoric.fk_niveauID_niveaux Left Outer Join ls.TraductionDefaut On ls.currentLevelHIstoric.fk_TraductionID_TraductionDefaut = ls.TraductionDefaut.pk_NoTraduction Left Outer Join ls.Traduction On ls.TraductionDefaut.pk_NoTraduction = ls.Traduction.No_Traduction and ls.Traduction.Langue = 1 Left Join ls.MandatsEx on ls.EmployeNiveau.fk_MandatID_MandatsEx = ls.MandatsEx.pk_MandatID Left Join ls.mandatExternalisation on ls.MandatsEx.pk_MandatID = ls.mandatExternalisation.fk_mandatID_MandatsEx left Join ls.Niveaux as NiveauPere on NiveauPere.niveauID = ls.currentLevelHIstoric.supId Left Outer Join ls.TraductionDefaut As TradDefautPere On NiveauPere.fk_TraductionID_TraductionDefaut = TradDefautPere.pk_NoTraduction Left Outer Join ls.Traduction As TradPere On TradDefautPere.pk_NoTraduction = TradPere.No_Traduction and TradPere.Langue = 1 Where ls.EmployeNiveau.fk_EmploID_Emplos = 345158 and (convert(varchar, ls.currentEmployeeLevelHistoric.DebAssign, 112) <= '20060802' and (ls.currentEmployeeLevelHistoric.FinAssign is null or convert(varchar, ls.currentEmployeeLevelHistoric.FinAssign, 112) >= '20060802'))

I'm running into an issue when developing a clr project. I open the project to make changes and apparently it hoses up the sql server that I'm connecting to. I'm opening the CLR Project from a mapped drive on another computer. I can't figure out why just opening up the project causes the slow down. Any ideas.
We have a process here where a ~45Gb is copied from DB1 to DB2 (both on the same server) using the Export Data wizard and choosing the "Transfer objects and data between SQL Server 7.0 databases" - All the defaults are left as is.
Under 6.5 this method took around 24 - 26 hours, now with SQL 7.0 (SP3) it takes about 16 hours. That's great execpt towards the end of the copy it seems to be hogging most of the server resources - although the processors aren't mazed out.
Users of the other databases are having queries take 5+ mins when they normally come back in < 5 seconds. As soon as the copy finishes there query time return to 'normal'.
Anyone any ideas on where to start looking or how to analyse this problem.
We're having problems with our SQL 2000 SP3 standard server (on Win 2k3). Our quasi-data-warehouse application does data processing on feeds of approximately 7 million records. Once the data is loaded in the queries against that data and updates against large tables will often wait with PAGEIOLATCH_SH contention. To give an example, over 7 million rows I was testing something out in development and issued: UPDATE <Table> SET <VarcharColumn> = null, which took forever (over an hour) with the PAGEIOLATCH problem....meanwhile someone else using another database was completely blocked from making an update during that time. It seems like something is very wrong.
The server has 4 drives spinning at 15k rpm with some sort of a high end raid controller, so I'm sure it's not a slow i/o subsystem.
Has anyone experienced this behavior before? Is this an issue that's resolved in 2000 SP4?
The server being used is a Intel Xeon E5310 Clovertown 1.6GHz 2 x 4MB L2 Cache Socket 771 80W Quad-Core 2U Passive Processor.
The problem is that this server is slowing down everytime about 1000 users log into a forum which the server is running. I think that the server should be able to handle this many users with no problems but I am not sure if that is the case.. The problem is probably something to do with the SQL of the server I am guessing. The server is not mine but I want to help the owner of the server as well as the users who are trying to access this forum but cant because of this server issue. If I was able to get the SQL would I be able to fix this problem? I doubt you need this but the server url is www.smashboards.com
I am fairly new to servers and have never really set one up myself yet. Forgive me for my lack of knowledge about them.
Randomly getting "SQL Server does not exist or access denied" error from my server. All sites on my server lose connection to the MSSQL database on a windows 2005 server. Anyone know? There is truly no pattern, it just randomly loses access to the SQL server which is on the localhost. It's often different pages being browsed when it decides to crash. Sometimes it's a couple hours between crashes and sometimes just a few minutes. I've heard that I should check the log files, but I'm really not even sure what to check. Any suggestions appreciated. Traffic is really light on the server right now too.
Hi all, i am getting these type of errors in the managment tool where i try to look a stored p. or see the schema list or listing tables in a database.

hi guys, the following test script works fine and displays a list of cars from the fairly small database, but if I specify the sort order in the querystring, the page takes ages to display and usually times out. Can someone look over it please and tell me where I can fine-tune it for performance or redundant code? thanks M

I've been doing some experiments with speeding up copying tables ofapproximately 1 million rows between databases using BCP and BULK INSERT.I noticed that the total time for removing the indexes (non-clustered) andthen recreating them after the BULK INSERT was significantly less than justdoing the BULK INSERT with the indexes left there, even though I specifiedTABLOCK.I would have expected SQL Server not to update the index until the insertcompleted (given the table lock) and so removing the indexes would have noeffect. Can anyone explain why removing the indexes should speed it up?This is on SQL Server 7.CheersDave
Interestingly enough, I haven't come across this before. I have a SQL stored procedure which takes four parameters; periodstartdate (datetime), periodenddate (end time), hsgradyearstart (int), hsgradyearend (int)
[dbo].[CalculateActivityTotal]
-- Add the parameters for the stored procedure here
@periodstartdate datetime = '2007-01-01',
@periodenddate datetime = '2007-01-08',
@hsgradyearstart int = 1900,
@hsgradyearend int = 2007 AS...
If I run the stored procedure and pass the parameters using EXEC or
the stored proc takes well over ten minutes to run (it does a bunch of aggregation). If I modify the stored procedure to take no parameters, however, and I hardcode the dates in the stored proc using declare and set then it runs in 13 seconds. What could be causing my problem and how I can I go about resolving this? I need to pass the parameters via reporting server. Thanks!
Hello, I have a table with some data in it. What I want to do is to create a query that returns me randomly one of the records of the table. Can this be done?
If this is not possible from SQL server I have thought an alternative way. This is:
I want to return all rows of the table with SELECT *, but I want the select to return in the first column an autoincreament number for each row without the need to add an autoincrement field in the table. e.g
Table ------ Banana Tomatoe Aple ... ... Orange
Result from select ------------------ 1 Banana 2 Tomatoe 3 Aple . .... . .... 23 Orange
Can this be done? At least this way 1) I can travel to the end of the results (from ASP), 2) read the ID of the last row 3) Create a random integer number from 1 to last ID, 4) and finaly select the appropriate random row from that integer.
My issue is that I have 10 accounts that were assigned to 5 agents with each agent receiving 2 accounts. I would know like to randomly reassign the accounts with the only criteria being that the random allocation not reassign to the same agency and each agent gets 2 accounts again.
Data looks like below and I want to populate the randomly assigned agent in the "Second_Agent" column.
I have a very weird issue in my latest package. I run it and it just randomly stops. When I watch it in debug mode or not in debugging a command prompt window will flash for an instant (too fast to read) and then the package will stop. It stops inside of a for each loop and the "on completion" is never fired for the loop. I never receive any errors - its just like someone hit the stop button. Sometimes it will process hundreds of files before stopping, other times only a few. (And its not stopping on the same file each time.. it doesn't appear to be related to the file at all)
Any ideas what could be going on? How to troubleshoot?
Say you have a table that contains 1000 rows, you create a simple select statement with a where clause that returns 100 or so of those rows. Easy enough.
Now, let's say that you wish to modify that select so that out of the 100 rows that match the where clause criteria, you only wish to return 10 rows randomly (i.e., you could run this query multiple times and get different results). How exactly would you go about doing this, efficiently?
I've thought about creating a stored procedure that will query the initial 100 rows into a temp table with an additional column (to number the rows from 1 to 100). Then setting up a loop (10 iterations) that will then generate a random number from 1 to 100 and select that row number into another temp table. At the end of the loop I'll have my table of randomly selected records. I am sure there is probably a better way to do this...
"select * from sample order by newid()" im getting a set of rows. On refreshing this query i need the same set of rows to validate.(provided sufficient data in the table).
Hi there I need to fill database table randomly with 5 ordered numbers such as 43566 , 78578 , 92565 , .. to gain approximately 100000 row of a table . Is there a query ?

We have a .net 1.1 application that gets this both with MSDE and SSE but more with SSE.
It randomly crashes with this error on laptops where they have SSE or MSDE installed on the local computer. They're being referenced by the machineNameInstance because (Local)Instance had bugs in the past with network connections disappearing and us getting this error. Now we're getting this, especially with Intel Wireless Cards on a random but consistant basis.
Under SSE we've had to turn on tcp/ip to make our app run, which tells me that something is preventing it from using shared memory access, which I suspect is that we're not using (Local)Instance, so I tried switching it, and no dice, same problem.
Is anyone else getting this? It's driving us nuts!!!! (and pissing off customers)
I would like randomly change the order of the rows in my table. Is there any way to do that? I also have a question about random generator. Is it possible to get a repeatable sequence of random numbers between 1 and 10 in T-SQL? (for example 2,7,6,5,8,9,3,2,....each state with the same probability). But i need the same sequence every time i run my procedure. I know this is just a pseudo generator. I tried to use function rand([seed]) and change the seed value, but I got some strange results...(floor(rand([seed])*100))
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
hiiiiiiiiii plz help me........urgent my table is as follows CREATE TABLE [dbo].[tbl_photo_gallery]( [image_id_int] [int] IDENTITY(1,1) NOT NULL, [image_caption_vchr] [varchar](100) NULL, [image_path_vchr] [varchar](200) NOT NULL, [photo_cat_id_int] [int] NOT NULL, [posted_by_vchr] [varchar](45) NOT NULL, CONSTRAINT [PK_tbl_photo_gallary_1] PRIMARY KEY CLUSTERED ( [image_id_int] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY] now i wanna to get a randomly selected image_path_vchr(image path) from each photo_cat_id_int(category) i m doing this: select TOP (1) image_path_vchr from tbl_photo_gallery where photo_cat_id_int=1 ORDER BY NEWID() to get random image_path_vchr from category 1....only single category. but i wanna to use a simple query to get random image_path_vchr from each category without using any temporary table..... plzzzzzzzz help me out......... thanks in advance
