Jan 17, 2005I need to be able to specify which column to sort by, BUT SQL 2000 does not allow me to
SELECT * FROM #TempTable

You can see that @WHICHCOLUMN is can be Surname, Age ETC, I have tried to make it a variable but, it started complaining of @FIRSTREC not defined, what's going on pls help, However, how do you combine dynamic queries with parameters as the say

Select Query For Custom Paging
May 23, 2007 Hi,I
am working on this select query for a report on website users. The
resulting rows will be displayed in a datagrid with custom paging. I
want to fetch 100 rows each time. This is the simplified query,
@currpage is passed as a parameter. ________________________________________________________________________________DECLARE @table TABLE (rowid INT IDENTITY(1,1), userid INT)INSERT INTO @table (userid) SELECT userid FROM UsersSELECT T.rowid, T.userid, ISNULL(O.userid, 0)FROM @table TLEFT OUTER JOIN ( SELECT DISTINCT(userid) FROM orders)AS OON O.userid = T.useridAND T.rowid > ((@currpage-1) * 100) AND T.rowid <= (@currpage * 100)ORDER BY T.rowid________________________________________________________________________________If
I run this query it returns all the rows, not just the 100 rows
corresponding to the @currpage value. What am I doing wrong? (The
second table with left outer join is there as I need one field to
indicate whether the user has placed an order with us or not. If the
value is 0, the user has not placed any orders) Thanks.

Sorting On A Temporary Field With A Custom Paging Method
May 18, 2005I'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.
Better Method To Count Records In Custom Paging For SQL Server 2005
Jul 24, 2006heres 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.
Displaying Custom Properties For Custom Transformation In Custom UI
Mar 8, 2007Hi,
I am creating a custom transformation component, and a custom user interface for that component.
In
my custom UI, I want to show the custom properties, and allow users to
edit these properties similar to how the advanced editor shows the
properties.
I know in my UI I need to create a "Property Grid".
In
the properties of this grid, I can select the object I want to display
data for, however, the only objects that appear are the objects that I
have already created within this UI, and not the actual component
object with the custom properties.
How do I go about getting the properties for my transformation component listed in this property grid?
I am writing in C#.
Expression Editor On Custom Properties On Custom Data Flow Component
Aug 14, 2007Hi,
I've created a Custom Data Flow Component and added some Custom Properties.
I want the user to set the contents using an expression. I did some research and come up with the folowing:
Code Snippet
IDTSCustomProperty90 SourceTableProperty = ComponentMetaData.CustomPropertyCollection.New();
SourceTableProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
SourceTableProperty.Name = "SourceTable";
But it doesn't work, if I enter @[System:ackageName] in the field. It comes out "@[System:ackageName]" instead of the actual package name.
I'm also unable to find how I can tell the designer to show the Expression editor. I would like to see the elipses (...) next to my field.
Any help would be greatly appreciated!
Thank you
Expression Issue With Custom Data Flow Component And Custom Property
Apr 2, 2007Hi,
I'm trying to enable Expression for a custom property in my custom data flow component.
Here is the code I wrote to declare the custom property:
public override void ProvideComponentProperties()
{
ComponentMetaData.RuntimeConnectionCollection.RemoveAll();
RemoveAllInputsOutputsAndCustomProperties();
IDTSCustomProperty90 prop = ComponentMetaData.CustomPropertyCollection.New();
prop.Name = "MyProperty";
prop.Description = "My property description";
prop.Value = string.Empty;
prop.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
...
}
In design mode, I can assign an expression to my custom property, but it get evaluated in design mode and not in runtime
Here is my expression (a file name based on a date contained in a user variable):
"DB" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + "\" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + ".VER"
@[User::varCurrentDate] is a DateTime variable and is assign to 0 at design time
So the expression is evaluated as: "DB189912189912.VER".
My package contains 2 data flow.
At runtime,
The first one is responsible to set a valid date in @[User::varCurrentDate] variable. (the date is 2007-01-15)
The second one contains my custom data flow component with my custom property that was set to an expression at design time
When my component get executed, my custom property value is still "DB189912189912.VER" and I expected "DB200701200701.VER"
Any idea ?

Aug 16, 2006I am writing a custom task that has some custom properties. I would like to parameterize these properties i.e. read from a varaible, so I can change these variables from a config file during runtime.
I read the documentation and it says if we set the ExpressionType to CPET_NOTIFY, it should work, but it does not seem to work. Not sure if I am missing anything. Can someone please help me?
This is what I did in the custom task
customProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
In the Editor of my custom task, under custom properties section, I expected a button with 3 dots, to click & pop-up so we can specify the expression or at least so it evaluates the variables if we give @[User::VaraibleName]
Any help on this will be very much appreciated.

Paging
Oct 12, 2004Is 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?

Paging In Sql 2k
Dec 11, 2003I 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.
Paging In RS
May 9, 2008Hi 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

Paging Problems

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?

View 4 Replies View RelatedPaging Performance
Feb 21, 2003I 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?

Paging (Performance)
Nov 28, 2006Hello, 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

HELP: Paging And Sorting
Apr 13, 2008Hi 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
