Sorting + Paging A Large Table In Stored Procedure
May 6, 2007
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.

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

-- paging

@maximumRows INT = 999999,

However it is not saving in visual srudio 2005. it is saying 'ambiguous column name ID' does anyone know why?CREATE PROCEDURE PagedResults_New
(@startRowIndex int,
@maximumRows int
)
AS
--Create a table variable
DECLARE @TempItems TABLE
(ID int IDENTITY,
ShortListId int
)
-- Insert the rows from tblItems into the temp. table
INSERT INTO @TempItems (ShortListId)

-- Now, return the set of paged records
SELECT S.*FROM @TempItems t

WHERE ID BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1

I have a stored procedure which returns the results fine, i.e. my asp code of
do while not objRS.EOF
display record n
objRS.Movenext
Loop
Included in the stored procedure is the number of pages that are ultimately returned, however I don't know how to access that value from my asp code.
Here is the stored procedure. I want to get the value of PageCount from my ASP code????
CREATE PROCEDURE GetSortedPage(
@TableName VARCHAR(50),
@PrimaryKey VARCHAR(25),
@SortField VARCHAR(100),
@PageSize INT,
@PageIndex INT = 1,
@QueryFilter VARCHAR(100) = NULL
) AS
SET NOCOUNT ON
DECLARE @SizeString AS VARCHAR(5)
DECLARE @PrevString AS VARCHAR(5)
SET @SizeString = CONVERT(VARCHAR, @PageSize)
SET @PrevString = CONVERT(VARCHAR, @PageSize * (@PageIndex - 1))
IF @QueryFilter IS NULL OR @QueryFilter = ''
BEGIN
EXEC(
'SELECT * FROM ' + @TableName + ' WHERE ' + @PrimaryKey + ' IN
(SELECT TOP ' + @SizeString + ' ' + @PrimaryKey + ' FROM ' + @TableName + ' WHERE ' + @PrimaryKey + ' NOT IN
(SELECT TOP ' + @PrevString + ' ' + @PrimaryKey + ' FROM ' + @TableName + ' ORDER BY ' + @SortField + ')
ORDER BY ' + @SortField + ')
ORDER BY ' + @SortField
)
EXEC('SELECT (COUNT(*) - 1)/' + @SizeString + ' + 1 AS PageCount FROM ' + @TableName)
END
ELSE
BEGIN
EXEC(
'SELECT * FROM ' + @TableName + ' WHERE ' + @PrimaryKey + ' IN
(SELECT TOP ' + @SizeString + ' ' + @PrimaryKey + ' FROM ' + @TableName + ' WHERE ' + @QueryFilter + ' AND ' + @PrimaryKey + ' NOT IN
(SELECT TOP ' + @PrevString + ' ' + @PrimaryKey + ' FROM ' + @TableName + ' WHERE ' + @QueryFilter + ' ORDER BY ' + @SortField + ')
ORDER BY ' + @SortField + ')
ORDER BY ' + @SortField
)
EXEC('SELECT (COUNT(*) - 1)/' + @SizeString + ' + 1 AS PageCount FROM ' + @TableName + ' WHERE ' + @QueryFilter)
END

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

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

Hello, my table is clustered according to the date. Has anyone found an efficient way to page through 16 million rows of data? The query that I have takes waaaay too long. It is really fast when I page through information at the beginning but when someone tries to access the 9,000th page sometimes it has a timeout error. I am using sql server 2005 let me know if you have any ideas. Thanks
I am also thinking about switch datavase software to something that can handle that many rows. Let me know if you have a suggestion on a particular software that can handle paging through 16 million rows of data.

my procedure is like this
////////////////////////////////////
CREATE PROCEDURE dbo.test2
(
@Page_No int,
@PageSize int,
@RowCount int output
)
AS
declare @intBeginID int
declare @intEndID int
declare @Counter int
set @Counter = 1
select @RowCount = count(*) from project
declare cro_fastread cursor scroll
for select * from project order by sector
open cro_fastread
select @intBeginID=(@Page_No-1)*@PageSize+1
select @intEndID = @intBeginID+@PageSize-1
fetch absolute @intBeginID from cro_fastread
WHILE @@FETCH_STATUS = 0 and @Counter < @PageSize
BEGIN
set @Counter = @Counter + 1
FETCH NEXT FROM cro_fastread
END
close cro_fastread
deallocate cro_fastread
/////////////////////////////////////////
my problem is the "FETCH" method can only get a row at one time, so there would be return many recordsets, how can I merge all the return recordset into one.
thanks in advance!

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

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 Everybady
Currenctly I have facing a problem on how to create a stored procedure that able to filter the data and order it dynamically on selected row.
does anyone know how to do that
I have successfully create a stored procedure that able to order with any colume at any direction and select it from rownumber to another rownumber.
But i have failed to add another function with is where claus to do filtering on the data after ordering and selection
does anybody can give me a example about that?
Thanks a lot

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

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.

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 the following, which loads up a product search i now want to be able to sort it based on criteria such as price. This is what i have so far; String str = Session["subCategoryID"].ToString();
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["streamConnectionString"].ConnectionString);SqlCommand command = new SqlCommand("stream_CategoryResults", conn);
command.Parameters.Add("@subCategoryID", SqlDbType.Int).Value = str;command.CommandType = CommandType.StoredProcedure;
conn.Open();SqlDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
dgProducts.DataSource = reader;
dgProducts.DataBind();
conn.Close();
My question is would i need to have different stored procedures, for when loading it up, and when sorting it by price. This is what my stored procedure looks like;CREATE PROCEDURE stream_CategoryResultsByPrice
@subCategoryID INT
AS
SELECT DISTINCT Companies.companyName, Companies.companyLogo,SubCategories.subCategoryName, Products.productPrice, Products.productInfoURL FROM Companies INNER JOIN Products ON Companies.companyID = Products.companyID INNER JOIN SubCategories ON Products.subcategoryID = SubCategories.subCategoryID WHERE SubCategories.subCategoryID=@subCategoryID

Normally when I do a sort for a stored procedure I use something like this:
ORDER BY
CASE WHEN @SortOrder = 'FirstName' THEN FirstName
WHEN @SortOrder = 'LastName' THEN LastName
WHEN @SortOrder = 'Extension' THEN Extension
ELSE LastName
How do I get that into a dynamic SQL statement with proper quotes?
Most of the SQL left out for cleanliness. The order by below would be the ELSE condition.
CREATE PROCEDURE view_by_company
@entrytype nvarchar(50),@strYears nvarchar(20), @company nvarchar(20)
AS
Declare @SQL nVarchar(4000)
Select @SQL = 'SELECT Media_Tracking_Companies.COMPANY '
Select @SQL = @SQL + 'WHERE (LTRIM(STR(DATEPART(yyyy, dbo.Media_Tracking_Ad_History.ADDATE))) IN ('
Select @SQL = @SQL + @strYears + '))'
Select @SQL = @SQL + 'ORDER BY dbo.Media_Tracking_Ad_History.PUBLICATION, dbo.Media_Tracking_Publications.AdDate DESC '
exec (@sql)
GO

Hi I am trying to achieve something like:
ALTER PROCEDURE dbo.GetShares
@SortValue varChar(30)= SHARE_DESCRIPTION
as
SELECT SHARES.SHARE_DESCRIPTION, SHARES.SHARE_SYMBOL, SECTORS.SECTOR_NAME
FROM SHARES INNER JOIN
SECTORS ON SHARES.SECTOR_ID = SECTORS.SECTOR_ID
ORDER BY @SortValue
but it does not seem to be possible to use variable after order by
is there any way to achieve something with sorting by variable?

I have a stored procedure in my SQL 2005 Server database named Foo that accepts two parameters, @paramA and @paramB.In my ASP.NET page, I have these:<asp:GridView id="gv" runat="server" AutoGenerateColumns="true" DataSourceID="DS" AllowSorting="true" DataKeyNames="ID"/><asp:SqlDataSource ID="DS" runat="server" ConnectionString="<%$ ConnectionStrings:CS1 %>" SelectCommand="Foo" SelectCommandType="StoredProcedure" OnSelecting="DS_Selecting"> <asp:Parameter Name="paramA" Type="String" /> <asp:Parameter Name="paramB" Type="String" /></asp:SqlDataSource>In my setup, paramA and paramB are set in DS_Selecting(), where I can access the Command.Parameters[] of DS.Now, here's the problem. As you can see, the GridView allows for sorting. When you click on a header title to sort, however, the GridView becomes empty. My question is, how can I get the GV sorted and in the correct direction (i.e. asc/desc)? My first step in my attempt was to add another parameter to the SqlDataSource and sotred procedure Foo (e.g. @SortByColumn), then changed Foo appropriately: ALTER PROCEDURE Foo @paramA nvarchar(64), @paramB nvarchar(64), @SortColumn nvarchar(16) = 'SearchCount' AS SELECT * FROM Searches ORDER BY CASE WHEN @SortColumn='SearchCount' THEN SearchCount WHEN @SortColumn='PartnerName' THEN PartnerName ELSE ID ENDThat works find and dandy. But wait--I want to get the correct ORDER BY direction too! So I add another parameter to the SqlDataSource and Foo (@SortDirection), then alter Foo: ... SELECT * From Searchces ORDER BY CASE /* Keep in mind that CASE short-circuits */ WHEN @SortColumn='SearchCount' AND @SortDirection='desc' SearchCount DESC WHEN @SortColumn='SearchCount' SearchCount WHEN @SortColumn='PartnerName' AND @SortDirection='desc' PartnerName DESC WHEN @SortColumn='PartnerName' PartnerName WHEN @SortColumn='ID' AND @SortDirection='desc' ID DESC ELSE ID END ...But including DESC or ASC after the column name to sort by causes SQL to error. What the heck can I do, besides convert all my stored procedures into in-line statements inside the ASP page, where I could then dynamically construct the appropriate SQL statement? I'm really at a loss on this one! Any help would be much appreciated!Am I missing a much simpler solution? I am making this too complicated?

I want to sort a stored procedure based on a variable passed to it... what is the easiest way to do this? Here's an example of what I want to do:
sp_select_thing 10, 'thing_name', 'asc'
It would run the query then somehow evaluate parameters 2 and 3 to be placed in the ORDER BY clause. I'm not sure if they should be quoted as strings or not, I don't have an idea how to pass a "reference to a variable" as a parameter to a stored procedure... or even if such a thing is possible
Thanks!

Here's a question you'll never quit hearing: is there a convenient way to page through large recordsets in SQL Server 2000?
I'm writing some software which, for all intents and purposes, works like a messageboard: users can create threads, leave replies, and so on.
I have about a half million records in a few of my tables, and some of my queries return 1000s of results. I'd prefer not to return 1000s of records all at once, so I don't want to page my records in code; I'd rather page them in SQL Server. Naturally, I want to page replies. However, I don't know of a convenient way to page records in SQL Server 2000.

lets say we have more than 100 000 rows in Table1, and we want to view each 10 rows alone.... and by pressing on a NEXT button we will see the other 10 pages....
there is 2 buttons : NEXT and PREVIOUS
so can anyone tell me how to do that in SQL 2005, and what is correctly called.
I have found a code that does use ROW_NUMBER in order to view results between 2 numbers,
example: rows between 10 and 50....
but It is not what I want, so please I need some help, thank you

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?

Hello! This is my scenario...
Development - Visual Studio 2005
Database - MS SQL 2005
I have written a stored procedure that has a output parameter whose type is NVARCHAR(MAX). Then I use C# to wrap this stored procedure in OLEDB way. That means the OleDbType for that parameter is VarWChar.
This works fine if the string size is less than 4000. If more than 4000, the remaining part will be chopped off. The situation gets worst if I replace VarWChar with LongVarWChar. There is no error nor warning at compiling time. But there is an exception at run time.
So... Does anyone here can help me out? Thanks in advance.

Apologies if this post doesn't belong here.
We are in the process of moving steps from a large SQL job to a web portal. The intent here is to allow the user to manually trigger the jobs to run. The problem I am having is in determining a way to run these job steps in the background, thus allowing the browser to take control while the step runs. These jobs can take enough time that forcing the browser to wait is not an option.The steps have been consolidated into stored procedures so in order to run a step, one would call the sproc. What I would like to do is run this in a separate thread and let that thread end on its own while the server transfers back to the client. Is something like this possible? My understanding is that the thread would be orphaned once the browser takes control again. Thanks in advance for any advice.

Dear All!
I use a "Execute SQL Task" to call a Stored Procedure. My Stored Procedure have an input parameter with type: ntext. And in "Execute SQL Task", I set variable in Parameter Mapping as following:
Variable Name: User::xmlDocument (this variable is a String to store xml data)
Direction: Input
DataType: NVARCHAR
ParameterName: 0
When length of "User::xmlDocument" is too large then error is happen but on the contrary, "Execute SQL Task" run successfully.
So, Can you show me how to pass large data into stored procedure using "Execute SQL Task"?
I am looking forward to hearing from you
Thanks

Hi,
I've got some procedure which pages select query, the example is below:
Code Snippet
CREATEEND PROC GetCustomersByPage
@PageSize int, @PageNumber int
AS
Declare @RowStart int
Declare @RowEnd int
if @PageNumber > 0
Begin
SET @PageNumber = @PageNumber -1
SET @RowStart = @PageSize * @PageNumber + 1;
SET @RowEnd = @RowStart + @PageSize - 1 ;
With Cust AS
( SELECT CustomerID, CompanyName, CompanyAddress,
ROW_NUMBER() OVER (order by CompanyName) as RowNumber
FROM Customers )
select *
from Cust
Where RowNumber >= @RowStart and RowNumber <= @RowEnd end
How can I change this procedure in order to page the query OVER the column set as an argument?
In other words I would like to execute proc like:
- exec GetCustomersByPage 10, 1, 'CompanyName' which pages by CompanyName(...OVER (order by CompanyName)...)
- exec GetCustomersByPage 10, 1, 'CompanyAddress' which pages by ComanyAddress
Is it possible?

Hi All,
I am using store procedure to which we pass ...
1.Sql query (String)
2.Starting index (Integer)
3.Page size (Integer)
4.total records out (Integer)
It works fine for the simple queries like "select * from tblcountry" but give error in case when we have sort of inline query or order clause or some complex query etc.
Despite of what is happing in the procedure can any help me out with a simple store procedure to which i give any query , start index and page size it should give me record set according to the given page.
For example query could be 'Select * from tblcountry where countryid in (select * from tblteachers) order by countryname desc', start index=0 , page size is 100 and total records are 500.
Note:
When i pass this query to sql server directly using command object its exectued successfully (this mean that it will also run fine in query analyzer), but i want to use paging in sql server so that is why i need a procedure to implement paging and query could be any its fully dynamic but i will be a valid query.
Your help in this regard is realy apperciated...
