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

Finding the "pieces of information" I need to successfully install the SQL Server Express edition is so complex. Uninstalls do "not" really uninstall completely, leading to failure of SQL install. Can you suggest a thorough, one-stop site for directions for the order of app uninstalls and then the order for app installs for the following...
SQL Server Express edition
Visual Studios 2005
Jet 4.0 newest upgrade
.Net Framework 2.0 (or should I use 3.0)
VS2005 Security upgrade
Anything else I need for just creating a database for my VS2005 Visual Basic project?
I was trying to use MS Access as my backend db but would like to try SQL Express
The data file is a simple Unicode file with lines of text. BCPapparently doesn't guarantee this ordering, and neither does theimport tool. I want to be able to load the data either sequentially oradd line numbering to large Unicode file (1 million lines). I don'twant to deal with another programming language if possible and Iwonder if there's a trick in SQL Server to get this accomplished.Thanks for any help.Mark Leary----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==----http://www.newsfeeds.com The #1 Newsgroup Service in the World! >100,000 Newsgroups---= East/West-Coast Server Farms - Total Privacy via Encryption =---
I use SQLDataSource, bind to a GridView and a SelectParameter that gets it's value from a textbox. If the textbox is empty, then it returns all rows.How do I prevent the query and binding when the page first load? Thanks
Hi,in aspx I've SqlDataSource, in SelectParametersI can add ControlParameter and to load parametersfrom control Property, BUT I'm trying to do that:Is there way, when in <ControlParameter>to set parameter to be loaded from PAGE Property.something like that:aspx:<asp:SqlDataSource ID="_companyDS" runat="server" ConnectionString="<%$ ConnectionStrings:tihomir_dbConnectionString %>" SelectCommand="SELECT [companyID], [companyName], [companyInfo], [companyAddress] FROM [Companies] WHERE ([companyID] = @companyID)"> <SelectParameters> <asp:ControlParameter ControlID="Page" PropertyName="CompanyIdent" Name="companyID" Type="Int32" DefaultValue="0" /> </SelectParameters> </asp:SqlDataSource></asp:SqlDataSource>code behind:public partial class test : System.Web.UI.Page{ public int CompanyIdent { get { return ... some id ...; } }} Best Regards,Tihomir Ivanov Best Manager Software
Hi all, I have a webpage with a Datagrid that populates using a table adapter from a Stored procedure that exists in my SQL Database...If I run the Stored procedure in SQL Directly then it takes 20 Secs to return all records...If I run the webpage then it takes just over 20 Secs.. Great you say..But If I have the sorting option set in ASP.net and I click on a column to sort then off the page goes for another 20 secs to sort the data.. Is there a better way to do what I am doing here that will speed up the page load.. Ie..the data is returned once and then sorted... Is it Better / Quicker for me to create a table using the stored procedure and link to this from the website..Updating the table every couple of minutes ? Any advice please ? Ray..

yeah, you're right, it isn't totally clear: Quote: MS SQL Development forum discussing administration, MS SQL queries, and other MS SQL-related topics. i suppose "MS SQL" could be interpreted as "any product from microsoft that uses the sql language" but unfortunately what it really means is "microsoft sql server"
We€™re receiving the data as flat files, when I open up the file in notepad the characters look like the error€™d examples (see below). Open the file up in a texteditor where you can apply code page 1252 it display the characters correctly, which is expected behaviour!
I use SSIS to load these files into my database, applying the correct code page€¦
€¦however the data gets loaded in the incorrect form. Plus the database is collation €˜SQL_Latin1_General_CP1_CI_AS€™ which is code page 1252 so I can€™t see why I am getting these issues.
This is an example of the Umlaut (German chars) issues were getting, they€™re appearing in the database like this€¦.
We are running SQL Server 2014 Enterprise Edition (64-Bit) on Windows 2012 R2 Standard (64-Bit).
1. When to create indexes, before or after data is added? Please address Clustered and Non-Clustered Indexes.
2. To move indexes to it's own filegroup, is it best to create the NON-Clustered Indexes on the separate filegroup with code similar to the example below?
CREATE NONCLUSTERED INDEX IX_Employee_OrganizationLevel_OrganizationNode ON HumanResources.Employee (OrganizationLevel, OrganizationNode) WITH (DROP_EXISTING = ON) ON TransactionsFG1; GO
I have read the following links that states that if you create the Clustered Index on a separate filegroup, it would also move the base table to that particular filegroup. (So I take it that you ONLY can move NON-CLustered Indexes to a separate filegroup.)
Placing Indexes on Filegroups:
[URL]
By default, indexes are stored in the same filegroup as the base table on which the index is created. A nonpartitioned clustered index and the base table always reside in the same filegroup. However, you can do the following:
• Create nonclustered indexes on a filegroup other than the filegroup of the base table.
Move an Existing Index to a Different Filegroup:
[URL]
Limitations and Restrictions
• If a table has a clustered index, moving the clustered index to a new filegroup moves the table to that filegroup.
• You cannot move indexes created using a UNIQUE or PRIMARY KEY constraint using Management Studio. To move these indexes use the CREATE INDEX statement with the (DROP_EXISTING=ON) option in Transact-SQL.
I'm trying to look for an efficient way to select records from two tables, combine them (not just one set above the other) and also efficiently page the results as well as dynamically order by specific columns. So far I have this....
INSERT INTO @Temp SELECT i.ID, i.Name, Type = 'I' FROM Item i UNION SELECT p.ID, p.Name, Type = 'P'FROM Package p
SELECT * FROM @Temp ORDER BY Name ASC
I was going to then implement some sort of of ROW_NUMBER like paging and ordering on the @Temp table variable. Problem is there could be potentially 1000's or more Items and Packages and they would all go in this single Temp table before having records 1 to 10 returned. Is there a more efficient way of doing this before I proceed any further?
I'm still quite a beginner with the Report Designer and now I have faced a problem. My goal is to make a reports refresh each time it is loaded. I know that this can be done by using rs:clearsession = true-method but in order this to work, it should be added to each link. There are a lots of links in the reports we are using and therefore it would be more practical to find another way to refresh the report on page load. Is there any way to do this with some kind of code attached to each report? I'm using Visual Studio 2003 and my Reporting services 2000.
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.
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
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?
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".
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!
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.
I have created one reports but all the records are displaying on one page.find a solution to display the records page by page. I created the same report without group so the records are displaying in page by page.
Here I will describe my problem. 1. We are loading large amount of data from database on background thread which is starting on Application_start event in global.aspx.cs file.The data is later cached for subsquent request to improve the performance. 2. Now when we put the application on web farm garden, it is not able to load the application. 3. We are sending the request the servers through Router kind of application. 4 This application is working fine on single server enviornment.
I just have done the SSIS example in the tutorial document included when install SQL 2005 ENT. I have a problem that whenever I test to run, the service load all data from source with out noticing about the data (I mean it load all the data to the destination), I do it several time and it continue to load all without checking. That mean the data is dublicated when the schedule run???
I think there should be a paramete or something like that to help the engine just load the new data to the destination. Could you help please?
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.

Hello I have a project that uses a large number of MS Data access pages created in Access 2003 and runs on MS SQL2005.
When I am on lets say my client, (first page in a series) data access page and I have completed the fields in the (DAP), I am directing my users to the next step of the registration process by means of a hyperlink to another Data access page in the same web but in a linked or sometimes different table.
I need to pass data entered /created on the first page to the next page and populate the next page with some data from the first page / table. (like staying on the client name and ID when i go to the next page)
I also need the first data access page to open and display a blank or new record. Not an existing record. I will also be looking to creata a drop down box as a record selector.
Any pointers in the right direction would be appreciated. I am some what new to data access pages so a walk through would be nice but anything you got is welcome. Thanks Peter€¦
In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
