Paging And Sorting
Jan 20, 2008
Hi guys
I am wondering if anyone has any practical ways of sorting and paging within SQL server 2005. I have seen plenty of different example and there seems to numerous ways of doing it but i was wondering if anyone has a method that they have been using that they know works in enterprise level solutions and will work in the majority of cases as a standard. The method that has stood out thus far is Common table expressions but I am not sure if this is the best or optimal approach and whether it will work in with dynamic sorting.
Thanks

Hi guys
I know this topic has been gone overed a bit but it just seems that no one has a really good answer.
What i need it to be able to be able to pass in which index row i want to go from and to, as weel a a token which corresponds to how it should be sorted.
The problem with the methods that i have seen to do this is that they all use a case statement to handle the sorting like the below;
Code Snippet
;WITH TotalSales AS (
SELECT CASE @OrderBy
WHEN 'UnitPrice' THEN ROW_NUMBER() OVER (ORDER BY UnitPrice)
WHEN 'OrderQty' THEN ROW_NUMBER() OVER (ORDER BY OrderQty)
WHEN 'CarrierTrackingNumber' THEN (ROW_NUMBER() OVER (ORDER BY CarrierTrackingNumber))
END AS RowNumber,
CarrierTrackingNumber,
UnitPrice,
OrderQty
FROM Sales.SalesOrderDetail
WHERE CarrierTrackingNumber LIKE '%F%'
)
SELECT *
FROM TotalSales
WHERE RowNumber between @StartIndex and @StartIndex + 9
At the begging this looks really good but it turns out that this is really slow. In fact it is about twice as slow as using the below dynamic SQL:
Code Snippet
SET @SafeOrderBy = CASE @OrderBy
WHEN 'UnitPrice' THEN 'UnitPrice'
WHEN 'OrderQty' THEN 'OrderQty'
WHEN 'CarrierTrackingNumber' THEN 'CarrierTrackingNumber'
END
SET @temp = N'
SELECT *
FROM (
SELECT ROW_NUMBER() OVER (ORDER BY ' + @SafeOrderBy + ') AS RowNumber,
CarrierTrackingNumber,
UnitPrice,
OrderQty
FROM Sales.SalesOrderDetail
WHERE CarrierTrackingNumber LIKE ''%F%''
) SUB
WHERE SUB.RowNumber between ' + @StartIndexAlt + ' and ' + @StartIndexAlt + ' + 9'
EXEC sp_executesql @temp
Now for a whole heap of reasons I would like to avoid using dynamic SQL to do this but if the alternative means that my queries take twice as long i dont see i have much of a choice.
Does anyone have any ideas??
Thanks
Anthony

I apologize in advance, but this post might get somewhat lengthy.
I'm new to the whole pagiong and sorting in SQL Server 2005, and I'm trying to get my SQL to perform in a certain way but can't seem to nail it just down. Hopefully someone can provide some insight or direction. Here's the scoop:
The gui sorts on any column chosen. For example, there's USER, ADDRESS, CITY, STATE, ZIP. The gui allows you to choose how many rows you wish to display per page. If there are 500 rows that meet the search criteria and you choose five pages, there should be 100 records per page. Here's the code:
INSERT INTO #RESULTS
SELECT PY.PaymentId

I get back the rows I'm expecting and it looks fine. What I can't get to happen is the proper sort.
I get back records 1014 records - 1001 through 2014. I choose to display 400 records per page, so ther will be 3 pages total (1001 through 1400 on page 1, 1401 through 1800 on page 2, and 1801 through 2014 on page 3. All the records are sorted by RECORD NUMBER (1000, 1001, etc.)
What I would like to do is when I choose to sort on the column (ASC or DESC),
1.) The entire record set is esssentially retrieved again,
2.) The record set is resorted in the proper order
3.) The record set is redisplayed.
For example, if I'm on Page 2, and I choose to sort in DESCending order, Page 1 would then have records 2014 through 1615, Page 2 would display 1614 through 1215, and page 3 would have 1214 through 1001. Since I was already on Page 2, I would be seeing Page 2 with the new sort. Now when I resort , it just sorts the records on the individual pages, not the entire result set.
Hopefully this all made sense...!
If anyone has any advice or insight, please don't hesitate!
Thank You!!

Hi, can anyone tell me how I can get implement sorting and paging using a recursive query?
I have a created a stored procedure (bit like the simple example below), but would like to add in sorting and paging using order by and row_number().
DECLARE @CategoryID intSET @CategoryID = 12;WITH CTE_Example (CategoryID, CategoryName, ParentID, Depth, RowNum)AS(SELECT CategoryID, CategoryName, ParentID, 0 AS Depth, Row_Number() OVER (ORDER BY CategoryName) AS RowNumFROM Categories WHERE CategoryID = @CategoryIDUNION ALLSELECT Categories.CategoryID, Categories.CategoryName, Categories.ParentID, CTE_Example.Depth + 1 AS Depth, Row_Number() OVER (ORDER BY Categories.CategoryName) AS RowNumFROM CategoriesJOIN CTE_Example ON Categories.ParentID = CTE_Example.CategoryID)SELECT * FROM CTE_Example WHERE RowNum BETWEEN @Start AND @End ORDER BY RowNum
I think the problem comes down to the Union, appreciate if someone can help.
Many thanks,
Matt

As I said above, how do I put sorting + paging in a stored procedure.My database has approximately 50000 records, and obviously I can't SELECT all of them and let GridView / DataView do the work, right? Or else it would use to much resources per one request.So I intend to use sorting + paging at the database level. It's going to be either hardcode SQL or stored procedures.If it's hardcode SQL, I can just change SQL statement each time the parameters (startRecord, maxRecords, sortColumns) change.But I don't know what to do in stored procedure to get the same result. I know how to implement paging in stored procedure (ROW_NUMBER) but I don't know how to change ORDER BY clause at runtime in the stored procedure.Thanks in advance.PS. In case "ask_Scotty", who replied in my previous post, http://forums.asp.net/thread/1696818.aspx, is reading this, please look at my reply on your answer in the last post. Thank you.

I've made another topic before concerning this problem, but since it was really confusing, I will made one clearer (it was about orthodromic formula, in case you read it, but the problem change during the topic, so thats why im creating this new one too).
I have a stored procedure with custom pagin method inside, and I want to sort my records on a fields I create myself (which will receive a different value for each record.) Now, I want to sort on this temporary field. And since this is a custom paging method I can choose between many page. Now, for the first page, it sorts fine. But when I choose a page above the first one, the sorting is not right (the results all are wrong).
So my real question is: is it really possible to sort on a Temporary Field in a custom paging method (because I know I can do it without any problem on a real field from my table, it just doesnt work right when I try on a temporary field). I tried to solve my problem with this little SQL instruction, but it didnt give me any result yet:
SELECT TOP 20 PK, test = field_value FROM Table WHERE PK not in (SELECT TOP 10 ad_id FROM Table ORDER BY ?) ORDER BY ?
well thanks for taking the time to read this, any help woulb be appreciated.

This is for SQL Server 2000. The purpose of the procedure is to return a subset of a filtered and sorted result set. The subset, filter criteria, and sort column and sort direction can be set dynamically. It uses the rowcount technique for paging.
This would be used to drive an ASP.NET gridview which supports filtering of the data, paging, and sorting. Please let me know what improvements I can make or if you have an idea for a better solution. (I didn't put this in a vBulletin code block because personally I find two sets of scroll bars annoying, but I can if people think it's better).
CREATE PROCEDURE dbo.Books_GetFilteredSortedSubset

User's requirement:
use the SP get the dataset from DB at once.
Want to make an accurate count of paging ( 200 rows /page) at the SSRS side.
Need to provide sorting, user just need to click the according column header's caption.
The design is:
we add group to devide the data into 200 per unit. Choice 'page break at end'.
add 2 Report Parameters, SD & SF, means sorting direction and Field.
In the Table Parameters add:
=IIF(Parameters!SD.Value="Ascending",Fields(Parameters!SF.Value).Value,"")
=IIF(Parameters!SD.Value="Descending",Fields(Parameters!SF.Value).Value,"")
everything seems OK at this time, and the rpt is very quick.
The Bug is:
Test team found out the sorting was broken by group, because we Choice 'page break at end'.
Noe the sorting scope is just the first page (first group)
Help wants:
query DB once , Accurate paging, full scope sorting.

I have a report where I am giving the users a parameter so that they can select which field they would like to sort on.The report is also grouping by that field. I have a gruping section, where i have added code to group on the field I want based on this parameter, however I also would like to changing the sorting order but I checked around and I did not find any info.
So here is my example. I am showing sales order info.The user can sort and group by SalesPerson or Customer. Right now, I have code on my dataset to sort by SalesPerson Code and Order No.So far the grouping workds, however the sorting does not.
Any suggestions would help.
Thanks

SSRS 2012 - VS2010...The report compares two years with a sort order on a value that has been engineered based on text switched to int. When sorting A-Z this is the result in the horizontal axis is: 5th, K, 1st, 2nd, 3rd, 4th, 5th..When sorting Z-A the result in the horizontal axis is:5th, 4th, 3rd, 2nd, 1st, PreK..Z-A is correct but A-Z sorting shows 5th as the start and end. The magnitude of the PreK location is correct but the label is wrong on the A-Z sort order. The sorting is implemented using the Category Group sorting option.

Is 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?

Hello,
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.
I have a output param itemCount which should return the total rows. Them I am creating a temp table to fetch the records for each page request. My output param works fine if I comment out all the other select statements. But returns null with them. Any help would be appreciated.
CREATE PROCEDURE [dbo].[CMRC_PRODUCTS_GetListByCategory]( @categoryID int, @pageIndex INT, @numRows INT, @itemCount INT OUTPUT )AS
SELECT @itemCount= COUNT(*) FROM CMRC_Products where CMRC_Products.CategoryID=@categoryID Declare @startRowIndex INT; Declare @finishRowIndex INT; set @startRowIndex = ((@pageIndex -1) * @numRows) + 1; set @finishRowIndex = @pageIndex * @numRows
DECLARE @tCat TABLE (TID int identity(1,1),ProductID int, CategoryID int, SellerUserName varchar(100), ModelName varchar(100), Medium varchar(50),ProductImage varchar(100),UnitCost money,Description varchar(1500), CategoryName varchar(100), isActive bit,weight money)
INSERT INTO @tCat(ProductID, CategoryID,SellerUserName,ModelName,Medium,ProductImage,UnitCost,Description,CategoryName, isActive,weight)SELECT CMRC_Products.ProductID, CMRC_Products.CategoryID, CMRC_Products.SellerUserName, CMRC_Products.ModelName, CMRC_Products.Medium,CMRC_Products.ProductImage, CMRC_Products.UnitCost, CMRC_Products.Description, CMRC_Categories.CategoryName, CMRC_Products.isActive,CMRC_Products.weightFROM CMRC_Products INNER JOIN CMRC_Categories ON CMRC_Products.CategoryID = CMRC_Categories.CategoryIDWHERE (CMRC_Products.CategoryID = @categoryID) AND (CMRC_Products.isActive = 1)
SELECT ProductID, CategoryID,SellerUserName,ModelName,Medium,ProductImage,UnitCost,Description,CategoryName, isActive,weightFROM @tCat WHERE TID >= @startRowIndex AND TID <= @finishRowIndexGO

I am using a stored procedure to page some objectsThe procedure looks like this:
CREATE PROCEDURE sw20aut.sw20_Kon( @sid_nr INT, @sid_stl INT = 35, @kid int )AS BEGIN SET NOCOUNT ON DECLARE @rader INT, @sid_antal INT, @ubound int, @lbound int SELECT @rader = COUNT(*), @sid_antal = COUNT(*) / @sid_stl FROM sw20aut.sw_kontakter WITH (NOLOCK) WHERE kund_id = @kid AND del = '0'
IF @rader % @sid_stl != 0 SET @sid_antal = @sid_antal + 1 IF @sid_nr < 1 SET @sid_nr = 1 IF @sid_nr > @sid_antal SET @sid_nr = @sid_antal SET @ubound = @sid_stl * @sid_nr IF(@sid_antal > 0) SET @lbound = @ubound - (@sid_stl - 1) ELSE SET @lbound = 0 SELECT CurrentPage = @sid_nr, TotalPages = @sid_antal, TotalRows = @rader
DECLARE @ename VARCHAR(64), @fname VARCHAR(64), @konid VARCHAR(64) SET ROWCOUNT @lbound SELECT @ename = enamn, @fname = fnamn, @konid = kon_id FROM sw20aut.sw_kontakter WITH (NOLOCK) WHERE kund_id = @kid AND del = '0' ORDER BY enamn, fnamn, kon_id SET ROWCOUNT @sid_stl SELECT kon_id, enamn, fnamn FROM sw20aut.sw_kontakter WITH (NOLOCK) WHERE enamn + fnamn + '~' + CAST(kon_id as VARCHAR(64)) >= @ename + @fname + '~' + @konid AND (kund_id = @kid AND del = '0') ORDER BY enamn, fnamn, kon_id SELECT startid = @konid SET ROWCOUNT 0END
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?
thanks.

Hi,
My application runs this query using a stored proc
SELECT empid1,name1,joindate from emp where empid2=3
union
select empid2,name2,joindate from emp where id1=3
Now I want to implement paging for the same using Row_Number so that I can display the results in pages.
Can someone please help me write a query for the same. I tried playing with Row_Number but no luck with it.Basically I am not good with SQL and I had programatically implemented paging in asp.net by looping through all records returned by the query.
Thanks,
Ganesh

Hello, I have incorporated a paging query in my software. I got the query from here:
http://rosca.net/writing/articles/serverside_paging.asp
My web software ususlly responded in .005 - .02 seconds with about a 100 rows of data. When I put simulated data on my database I added about 2 million rows. when I did this -- every page that did not execute the paging query responded lightning fast. But the webpages that executed the paging query took over 5 seconds. I dont understand why this paging query brought my web application to its knees.
Does anyone know of a more efficient way to do paging. I have SQL server 2000. If it may be easier I can upgrade to SQL 2005. PLZ Let me know. Thanks

let's suppose that we have a table entitled "tab1" which has more than 1000 rows and about 10 columns
so in SQL 2000, if I do this query:
SELECT * FROM tab1
the result will be displaying all the rows from the begining.
and my teacher told me that there's a new option in SQL 2005 which is you can display the result of the query in a page mode.
so can anyone tell me how can I do so for this query:
SELECT * FROM tab1
so that I can see the results in pages.
thanks
