Is it necessary (or perhaps just beneficial, if not necessary) to create a paging file on the drive where SQL Server is installed along with the paging file on the OS drive. For example, Windows NT 4 is installed on the C drive, and SQL Server is installed on the D drive. Should I have a paging file on both drives. Someone mentioned to me that you should have a paging file for both drives, but I had never heard of that before.

Hiii all
SQL Server 2000 or 2005 dose not support the LIMIT statement like mySQL. So plz can anyone tell me tht how to do paging in SQL Server?? Without using CLR Integration...
Since Row_Number() is not available to SQL Server 2005 CE, are there any other alternatives for paging when querying the database?
Thanks.
suppose from my code behind i will pass my sql query to sql server store procedure and i want that scriptwill be written in such a way that my store procedure will execute my query and populate cursor and then cursor will be return from my store procedure to code behind.so i want to know is it possible in sql server if so pls give me a sample sql server store procedure code.

My SQL Server Version is: Microsoft SQL Server 2008 (SP3) - 10.0.5500.0 (X64)
I am using derived tables to Page data on the SQL Server side.I used this link as my mentor for doing paging on the SQLServerhttp://msdn2.microsoft.com/en-us/library/ms979197.aspxI wanted to use USER PAGING, thus I used the following code:CREATE PROCEDURE UserPaging(@currentPage int = 1, @pageSize int =1000)ASDECLARE @Out int, @rowsToRetrieve int, @SQLSTRING nvarchar(1000)SET @rowsToRetrieve = (@pageSize * @currentPage)SET NOCOUNT ONSET @SQLSTRING = N'selectCustomerID,CompanyName,ContactName,ContactTitle from( SELECT TOP '+ CAST(@pageSize as varchar(10)) +'CustomerId,CompanyName,ContactName,ContactTitle from( SELECT TOP ' + CAST(@rowsToRetrieve as varchar(10)) +'CustomerID,CompanyName,ContactName,ContactTitle FROM( SELECT TOP ' + CAST(@rowsToRetrieve as varchar(10)) +'CustomerID,CompanyName,ContactName,ContactTitle FROM Customers as T1ORDER BY contactname) AS T2 ORDER BY contactname DESC ) AS T3)As T4 ORDER BY contactname ASC'EXEC(@SQLSTRING)RETURNGOWhen I use this. Assume that the Total records returned by the SQLquery is 1198.Thus when I am on Page1 the above Stored Proc (SP) willreturn the first 1000 records.This works absolutely fine.Now I am on Page2, now I need to retrieve only the remaining 198records.But if I use the above SP, it will return the last 1000records.So to tweak this I used the following logic to set the@pagesize variable:Declare @PageCount intselect @PageCount = @TotalRows/@PageSizeif @currentPage @PageCount SET @PageSize = @TotalRows%@PageSizeSince I am on Page2 the above logic will set the PageSize to 198 andnot 1000.But when I use this logic, it takes forever for the SP toreturn the 198 records in a resultset.However if the TotalRows were = 1800, and thus the PageSize=800 orgreater, this SP returns the resultset quickly enough.Thus to get over this problem I had to use the other logic i.e. usingApplication Paging (i.e. first storing the entire result set into aTemp table, then retrieving only the required records for the PAGE)Can anyone suggest what is wrong with my user paging logic?????TIA...

I have a webpage that displays 4000 or more records in a GridView control powered by a SqlDataSource. It's very slow. I'm reading the following article on custom paging: http://aspnet.4guysfromrolla.com/articles/031506-1.aspx. This article uses an ObjectDataSource, and some functionality new to Sql Server 2005 to implement custom paging.There is a stored procedure called GetEmployeesSubestByDepartmentIDSorted that looks like this:ALTER PROCEDURE dbo.GetEmployeesSubsetByDepartmentIDSorted( @DepartmentID int, @sortExpression nvarchar(50), @startRowIndex int, @maximumRows int)AS IF @DepartmentID IS NULL -- If @DepartmentID is null, then we want to get all employees EXEC dbo.GetEmployeesSubsetSorted @sortExpression, @startRowIndex, @maximumRows ELSE BEGIN -- Otherwise we want to get just those employees in the specified department IF LEN(@sortExpression) = 0 SET @sortExpression = 'EmployeeID' -- Since @startRowIndex is zero-based in the data Web control, but one-based w/ROW_NUMBER(), increment SET @startRowIndex = @startRowIndex + 1 -- Issue query DECLARE @sql nvarchar(4000) SET @sql = 'SELECT EmployeeID, LastName, FirstName, DepartmentID, Salary, HireDate, DepartmentName FROM (SELECT EmployeeID, LastName, FirstName, e.DepartmentID, Salary, HireDate, d.Name as DepartmentName, ROW_NUMBER() OVER(ORDER BY ' + @sortExpression + ') as RowNum FROM Employees e INNER JOIN Departments d ON e.DepartmentID = d.DepartmentID WHERE e.DepartmentID = ' + CONVERT(nvarchar(10), @DepartmentID) + ' ) as EmpInfo WHERE RowNum BETWEEN ' + CONVERT(nvarchar(10), @startRowIndex) + ' AND (' + CONVERT(nvarchar(10), @startRowIndex) + ' + ' + CONVERT(nvarchar(10), @maximumRows) + ') - 1' -- Execute the SQL query EXEC sp_executesql @sql ENDThe part that's bold is the part I don't understand. Can someone shed some light on this for me? What is this doing and why?Diane

I'm using ComponentArt's Callback grids with Manual Paging.
The CA example grid uses Access:(http://www.componentart.com/webui/demos/demos_control-specific/grid/programming/manual_paging/WebForm1.aspx)
That SQL syntax produced is invalid in SQL Server 2005.
Example:
"SELECT TOP " & Grid1.PageSize & " * FROM (SELECT TOP " & ((Grid1.CurrentPageIndex + 1) * Grid1.PageSize) & " * FROM Posts ORDER BY " & sSortColumn & " " & sSortOrderRev & ", " & sKeyColumn & " " & sSortOrderRev & ") ORDER BY " & sSortColumn & " " & sSortOrder & ", " & sKeyColumn & " " & sSortOrder
So...This is what I have (simplified), and it appears return incorrect rows on the last few pages:
SELECT top 15 * FROM Posts where & sFilterString & " and Postid in (SELECT TOP " & ((Grid1.CurrentPageIndex + 1) * Grid1.PageSize) & " Postid FROM Posts where " & sFilterString & " ORDER BY " & sSortColumn & " " & sSortOrder & ") " & " ORDER BY " & sSortColumn & " " & sSortOrderRev
What other approaches has anyone used besides the "ID in (...)"?The examples I have included show the available variables: sort asc and desc, current page, number of rows on a page, etc.

Hi gurus,
I've created a linked server (and set up the corresponding schema.ini file) in order to perform bulk-inserts from some CSV text files into SQL tables (from my standpoint the text files are just for reading purposes). The linked server works fine (I can select the data in the files without a problem).
Now the question: is possible to automatically detect when one or more of those files change in order to start the import process automatically? Something like having a trigger created on the CSV files Or there's no easy way to do that so I have, to say something, to create a Job that periodically checks if the files have changed programatically (say, recording each file's timestamp everytime is imported and comparing the recorded value with the current one, or whatever)?
Thanks a lot in advance!

View 2 Replies View Relatedheres my problem, since I migrated to SQL-Server 2005, I was able to use the Row_Number() Over Method to make my Custom Paging Stored Procedure better. But theres onte thing that is still bothering me, and its the fact the Im still using and old and classic Count instruction to find my total of Rows, which slow down a little my Stored Procedure. What I want to know is: Is there a way to use something more efficiant to count theBig Total of Rows without using the Count instruction??? heres my stored procedure:
SELECT RowNum, morerecords, Ad_Id FROM (Select ROW_NUMBER() OVER (ORDER BY Ad_Id) AS RowNum, morerecords = (Select Count(Ad_Id) From Ads) FROM Ads) as testWHERE RowNum Between 11 AND 20
The green part is the problem, the fields morerecords is the one Im using to count all my records, but its a waste of performance to use that in a custom paging method (since it will check every records, normally, theres a ton of condition with a lot of inner join, but I simplified things in my exemple)...I hope I was clear enough in my explication, and that someone will be able to help me. Thank for your time.
I am monitoring our production server, and noticed that periodically we have spikes of Memory Paging Rate (pages/sec).
How to find particular queries/stored procedures that causing this?
We have several 2005 servers with "Maximum server memory" set to 214 gig, which I believe is the default at installation time. I am told that this means "use all the memory there is including paging." Well, this is nuts but the servers seem to work fine with this setting no matter how much physical memory they have.
One of our 2005 servers recently started paging like crazy, so I reduced "Maximum server memory" to 6000 and the paging disappeared (server has 8 gig of physical memory) and the server appears happy.
I can not explain why only this one server has this paging issue and the others do not. Should I be setting "Maximum server memory" on all my servers? Are there other considerations which might cause the server to eat-up all the memory? As far as I know no other applications run on this box.
Thanks,
Michael
I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.

View 3 Replies View RelatedIs there any way to implement a paging scheme such that only the required records are transferred from SQL Server to the asp.net app?
The only support I can find such as the DataAdaptor.Fill will bring all the records back from SQL Server and then create the page...
This obviously still takes time and memory based on the entire query, not the page size.
Any ideas?

View 3 Replies View RelatedHello,
How can I do paging in my SQL Server stored procedure.
I have thought of a way, but I need to :
"SELECT TOP @Count..."
which is not allowed :S
What can I do to get around this?
I have noticed that the server i'm running SQL2k on is starting to page out of the norm. I can see that the regsvc and sqlservr svc are showing high page faults/sec. I have 3 gigs of ram and set the max that sql can use to 2 gigs. It is currently using only 168 MB and still will show high paging at random times. I know I can add more ram but that doesn't seem to be the problem. I have also stopped unnecessary services at the os level.
Any other suggestions to fix this?
Thanks in advance.
Hi there
I've managed to make it query that return a dataset that have 2 views utilising the "Filter" in RS. I treat this as a single record with multiple views.
Now let say if I have a stored precedure that pass 2 parameters one is called state and year and accepting 'ALL' for every possibility of State and Year and construct that into single dataset with 2 views similar like above.
How do I breakdown this in the reporting services so it will have paging?
This is a simple dataset:
RECORDID, ReportViewType, State, Year, VALUE
1, "VIEW1", "NSW", 1, null
1, "VIEW2", null, null, 10000
2, "VIEW1", "NSW", 2, null
2, "VIEW2", null, null, 11000
3, "VIEW1", "VIC", 1, null
3, "VIEW2", null, null, 11003
4, "VIEW1", "VIC", 2, null
4, "VIEW2", null, null, 11001
I would like to break down (paging) this per recordid. Each page obviosuly has 2 views using the same data set with different FILTER.
Do I need to put into a LIST then inside that list put 2 TABLES? Is this possible?!?!
Thanks
I have created a stored proc for paging on a datalist which uses a objectDataSource.

The big problem is that i need to display objet with the same name. In my book the best identifier is the PK and therefor i have sorted as above by ordering after LastName, FirstName, ContactId
After som thinking ive reached the conclusion that this dont work if the idnumbers isnt of the same length. as long as they are(for example two people named John Smith, one with id = '23' and one with id = '87' it works. If there ids would have been '23' and '1203' it will not work correctly) of the same length it works fine.
What im wondering is if anyone have a good solution to this? Only thing i can think of is filling all idnumbers with zeros to equal length. Dont know how and if this will affect performance though. Anyone has a practical solution to this?

I have a paging dilema with an ADO/ASP web based application.
Currently I am using the temp table and inserted index method of paging which works well but the pages that use this paging have a variety of filters on them and a largish subset of data available. This means that every time the page is refreshed the code is creating that temporary table, inserting all the data, selecting the subset and then dropping it.
I was looking for a more efficent way of getting paged data to the client. One of the alternatives I came across was using a server side forward only cursor and the ado getrows() method. This sounds good in princible but I don't know if I am going to get a performance hit by using a server side cursor as opposed to sending the entire recorset to the client and letting it page the results.
Would it be any better to use a stored procedure and pass the full sql statement to it. I can't actually write the sql into the stored procedure becuase it is all totally dynamic.
So I guess I have three options, temp tables, server side cursor and small amounts of data sent to the client or client side cursor and large amounts of data sent to the client.
Any ideas or recomendations?
Is this a correct statement? When commit Charge total (k) is greater than Physical Memory total (k) then the server is paging badly, correct?
