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.

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.
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.

Is there any easy way to detect SQL Server memory is getting paged out? Any DMV query or tips to confirm it is paging out.
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
View 4 Replies View RelatedHi,
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.

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
Our monitoring tool shows that our production system periodically experiencing large rate - up to 800 memory pages/sec. How to find out which particular queries, S.P., processes that initiate this?
View 3 Replies View Related In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static
for select name, salary from ag
open ll
fetch from ll
while @@FETCH_STATUS=0
fetch from ll
update ag set salary=200 where 1=1
close ll
deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

Hi. I have a cursor in my SQL Server 2000 usp that doesn't seem to be working. It returns 0's for all counts within the cursor.

How do I create a "Cursor" in SQL Server 7.0 that compares an imported table against a exsisting table? Ex. Table1 is my existing table(Destination), Table2 is my imported table(source). I would like to update records in the Destination from the Source but I have to be aware of these three scenarios.
1. If the record exist in the Destination and the Source I will do nothing.
2. If the record exist in the Source and not in the Destination then I will add the record to the destination.
3. If the record exist in the Destination and not in the Source then I will write to the transaction Log.
Note: I am only concerned about updating one column in Destination which matches the only column in the source.

I am not fimilar with cursors at all but need some assistance/direction on how to re-create the following.

I'm needing to convert an oracle cursor to Sql Server 2005. If at all possible I would like to stay away from the cursor and create this some other way. Any help would be greatly appreciated.

Forgive me if this is a stupid question.
How do you use a Server Side block cursor?
Lets say I have a db of 250,000 items and I want to retrieve the data 100 rows at a time.
How would I do this (using a block cursor, not in general)
thanks,
adding a if statement within my cursor.
Use master
GO
DECLARE @dbname VARCHAR(50)
DECLARE @statement NVARCHAR(max)
DECLARE db_cursor CURSOR
LOCAL FAST_FORWARD
[code]....
The cursor should only grant access to a particular database. If the user exists within the database it should not execute the script.
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?
I have a table with a lot of records. I want to make paging without passing all the data back to a dataset. I know how to select the top n rows but how do I select 10-20 for example.
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
