I want to build a system that will have about 1 million rows in a
table in sql server database.I am using this for a web application and
accessing it via JDBC type 4 driver.But display 20 records at a time
only using pagination(as in google).What will be the best way to go
about this.
I need sql script where i will pass startindex, endindex and sortcol and order then query return result accordingly. it would be better if query looks small and dynamic.
Here one sample of dynamic sql but there case is used which is not require.
DECLARE @sql NVARCHAR(MAX)
SET @sql = ';WITH cte as(SELECT *,
ROW_NUMBER() OVER
(ORDER BY ' + CASE (@SortColumn + ':' + @SortDirection)
[Code] ...
My requirement is that i will create a sp where i will pass start index and end index and sort column,sort order and filter means where clause and sp will generate and execute dynamic sql and return data. i need a sample of that kind of sp.
I have a tried two different reports one with table and the other without The last textbox in both reports contains enough text which should fill half of first page and half of second page. In both reports the print preview and export to PDF keeps the first page blank and puts all the data in the second page. It appears that the textbox control doesn't know when to place a pagebreak when in print preview and export to PDF. The rdl file has no pagebreaks defined anywhere. Thanks in advance for your help!
I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A:
(name phone house cost of house,zipcodecountystatecountry)
-a view will later split this large varchar string basedÂ
column b: is the source filename of the data load (varchar 256)
....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?
Hi,
My requirement is that when i show data the vertical scroll bar should be disabled.ie,whatever data can be accomodated in a screen should be shown and the rest should go to next page.
I have tried restricting the no of rows shown to 20 but this wont work always as the font size may change.I had used the follwing for this:
<GroupExpression>=Ceiling(RowNumber(Nothing)/20)</GroupExpression>
is there any other way???
please help...
Hi,
I have recently moved into ms sql from mysql and having problems with
finding a query to help paginate my search results. In mysql I would
use:
SELECT * FROM tablename WHERE something = something LIMIT 0,10
what would a similar query be in sql server?
From what I have experienced so far I know this is going to be a big query!
Thanks in advance

I have a report which consists of a list item, in which is a rectangle containing a header (as a subreport, but I think that's not relevant) and a subreport. The aforementioned rectangle is specified to include a pagebreak after each occurrence, but that pagebreak is not working as expected.
When I run the report I get 1 subreport on the first page, and exactly two on each subsequent page. Other than the pagination, I am getting very close to what I want. It's too bad that the subreport's pagination is ignored, but I can live with that for now.
Things I've already tried:
The report's pageSize and interactiveSize are both set to landscape
The subreport's report's pageSize and interactiveSize are both set to the actual size that the subreport takes up on the main report (which is ignored anyway)
The list does not have any of the page break options selected.
Any Ideas?
Hi,
I have found the follwing article on internet. This article states two keywords LIMIT and OFFSET using which we can implement the pagination type of functionality in MySQL or PostgreeSQL,
http://www.petefreitag.com/item/451.cfm
But is there any way using which we can implement pagination kind of functionality in SQL.
LIke first time if i set 0 thenm it fetch the records from 1-10 then if i set 10 then it will fetch the next set of records from 11-20 like this,
Can we do it in SQL?????
I'm working on a website where we're using .Net web services to feed data to a Flash front-end. The site will have a comments section and we want to display 15 or so comments per page with 'back' and 'next' functionalitiy. We'd also like to show the number of pages of comments and highlight the page they're on. The standard stuff that datagrids do so well. How can this be accomplished without a datagrid? There's a good page that explains a number of ways to do this using classic ASP. Some of the solutions they implement I can most likely use with .Net.http://www.aspfaq.com/show.asp?id=2120But I wanted to ask the community. How to paginate without a recordset? Sql Server 2000 back-end, ASP.NET 1.xThanks.

I'm still quite new to MSSQL so excuse the trivial questions.
I've already tried searching through the forums on pagination as im sure its a big subject but couldn't find the answers i'm after.
I'm using MSSQL 2000 and asp .net 2.0 and basically need to paginate my results. My database contains roughly 250,000 rows of data, and one query would approximately return 30 results at the most. I would want to have 5 results per page.
I'm starting from scratch so was wondering what technique i could use. I can't use OFFSET as thats MySQL, is there an equivalent?
I've heard mixed opinions on Cursors, but so far thats the only way i can see at the moment! :S
thanks
I am a PHP programmer for a small startup. We are storing person records and our MS SQL Server 2000 database has grown to the point where we wish to paginate the data before returning it to my PHP scripts.
I was wondering if anyone has any recommendations on an optimal way to manage this given the following requirements.
- Data must return only X number of rows at a time (user configurable).
- Must be able to search by several diffent criteria (name, date, birthday, location, ...)
Also, I was wondering if it is possible to return the total number of existant rows of data as the first row of a MSSQL procedure.
Let me know what you think about the following code:DECLARE @MaxIdValue intDECLARE @MaxSortFieldValue nvarchar(50)SELECT TOP 1 @MaxIdValue = [id], @MaxSortFieldValue = [SortField]FROM (SELECT TOP PageNumber*RowsPerPage [id], [SortField]FROM MyTableWHERE (FilterCondition) ORDER BY [SortField], [id]) TORDER BY [SortField] DESC, [id] DESCSELECT TOP RowsPerPage * FROM MyTableWHERE ([SortField] >= @MaxSortFieldValue) AND (([id] > @MaxIdValue) OR([SortField] <> @MaxSortFieldValue)) AND (FilterCondition)ORDER BY [SortField], [id]This is a dynamic SQL and it should be easily fixable.PageNumber, RowsPerPage, FilterCondition and SortField are going to bethe variables and will be based on the user's searchcondition/criteria.-----------------------------Thanks for you attention.

I have a problem with paging in my report. My report is quite simple, I have a table with two grouping levels. Paging is not appearing besides there is a lot of rows displayed.
When I change the report to use only one grouping level, the paging works fine. Is paging being calculated on the first grouping level ? I have about 10 to 20 rows at the first level but about 1500 rows on the second one.
Any help will be appreciated.
I changed a stored procedure that does pagination from the top style to the
bottom style - mainly to avoid errors in differences in the 2 queries (count
and select) and for conciseness. The performance on a large table for the
bottom query was amazingly bad. The query plan is very different too. It
was about 25 times slower on a 1 million row table. I am familiar with
other pagination techniques (temp tables with identity, TOP-TOP, etc), but
is there a way to use the ROW_NUMBER function AND get a count of records
back in a single query with decent performance?

Hello,
We are migrating from VB6/MySQL to VB6/MS SQL.
The application retrieves limited records for paginated results.
This way we can access large databases, but only return rows for one screen.
For example:
Select row 1 - 10, then 11 - 20 then 21 to 30 etc.
With MySQL we can use LIMIT and OFFSET and it works great.
MySQL
SELECT <columns> FROM <tables> [WHERE <condition>] [ORDER BY <columns>]
[LIMIT [offset,]howmany>]
Does anybody know how we can do something similar with MS SQL?
Any feedback is appreciated!
Thank you,
Edi
I have a need to perform pagination while using dynamic sorting. Asan exmaple -SELECT TOP(10) * FROM (SELECTTextColumn,DecimalColumn,ROW_NUMER() OVER (ORDER BYCASE @xWHEN 1 THEN TextColumnWHEN 2 THEN DecimalColumnENDDESC) AS SortOrderFROM Table1) AS Results WHERE SortOrder ( 10 ) ORDER BY SortOrderThis is obviously just some sample but an error is given because thedata type of the 2 columns used in the order by are different. Itworks if I cast DecimalColumn to match the textcolumn but then thesorting is wrong. Is there a way to do this in a single query with 2different data types?Thanks for your help.
View 2 Replies View RelatedI would like to know how to show all the records returned (upto 1000) in one single page on a web browser. I am able to get the required report in IE but in case of Firefox it hangs.
Did some test and found that Firefox is able to render a report of upto max 300 records in a single page without getting hanged but report is coming very slow. While you scroll the scroll bar it€™s moving with Jerks. with 200 records in a single page is not getting hanged but report is faster than 300 records display. But by 500 records Firefox hangs. I understand it might be depending on the hardware also but am not sure.
Can anybody give me a good solution to display upto 1000 records in a single page or if its a limitation, where can i get the documentation of it.
Thanks and regards

Hi,
We have developed few reports displaying data using chart layout. In the Data tab, we have specified MDX query that will return top 10 records.
But now, instead of restricting to just top 10 records, we would like to display all records and go in for pagination.
Is there some setting in the chart properties, where in I can display the first n records in first page, and the next n records( if available) in the next page and so on?
Can I specify the value of n somewhere in the propeties?
I read through many posts regarding pagination but those couldn't help me much.
Please help me in solving this problem.
Any help would be appreciated.
Thanks in advance!
I've got the following query:
WITH OrderedResults AS (SELECT some_table.*, ROW_NUMBER() OVER (ORDER BY some_field) as RowNumber FROM some_table)
SELECT TOP 10 *
FROM OrderedResults
WHERE RowNumber > 10;
which works well for returning "paginated" recordsets. But when it comes to displaying "page" links and next and previous links, I need a total count of records found... something along the lines of the MySQL CALC_FOUND_ROWS feature...
Is there some built-in MSSQL feature I can use for this, or do I have to do a SELECT count(*) FROM some_table to get this data?
Any advice is appreciated
I am using MS SQL 2000 server db.

i.e just want to fetch 100 records only per request
How can i do it with MS SQL 2000 server? any suggesions?

Hi,
I use an embedded ReportViewer control as a LocalReport in a web form. The report displays the results in four pages and I need to display them all in one page (without any pagination). Is there a way to disable pagination? Also, what do I need to do to show the print button in toolbar?
Thanks,

I know people use ROW_NUMBER() function to do the pagination but my below two query is bit complex. Sohow to use pagination there ? I used ROW_NUMBER() OVER(ORDER BY IsNull(A.OEReference, B.OEReference) ASC) as Line in one but not sure am i right or wrong.
IF IsNull(@GroupID,'') = ''
SELECT IsNull(PartGroupName, 'UnMapped') AS PartGroupName,
CASE IsNull(PartGroupName, '')
WHEN '' THEN ''
ELSE IsNull(IsNull(K.GroupID, IsNull(C.PartGroupID,'')),'')
END AS PartGroupID,

hello guyshere is my problem:i am developing a asp.net web app in .net 2.0. i have some sensitive data in my database. which is encrypted using DES ( with some key which is only known by the top level authorities ). now there is an option of changing the secret key. on changing the key the sensitive data has to decrypted using the old key and then again encrypted using the new key. Now if the no of records increases i am afraid that it might take a longer time and the application might look as it got hanged. guys i have no clue on how to do this. if you guys have any idea on how to implement this please let me know. any help would be appreciatedVignesh

I was wondering if anyone can help me.
I am trying to import data into SQL Server 7. The table will be 700-800 columns, and the data will be about 150,000 records at a time.
The data source is flat file.
First I create the table using a database schema, and secondly I would like to populate the table.
The problem is that most of the data is numeric, and to be used for statistical analysis.
So far I have tried Bulk Insert, bcp, and dts.
DTS is the only method that has worked in any way, shape or form, but that requires importing each column as a Varchar. Importing to my pre-created table doesn't work, because it is interpreting some of the source columns as character data and refusing to insert them into an int field.
Bulk Insert and bcp both give error messages, and I am wondering if that is because of the size of the insert statement that is required to handle so many fields.
For the moment I am just trying to import the data in any way, but eventually, it will have to be run as an automated process, with the table structure probably needing to be altered as well.
Any help/suggestions would be very greatfully received.
I have a web site that allows user to enter large strings into a database (comments, etc). What is the best way to do that? Right now I have them limited to 25 characters and the data type is varchar. Is there a better way?

when to use table variable and temp table. i told the interviewer that when rows is less like hundreds or thousand then use table variable else use temp table.After that he asked that what do u mean by less data or thousand rows may be there are multiple columns involved with that less rows and make a huge data set.

I have simplified my question. For complex presentations of data it appears to me that the best practice is to put complicated code into a stored procedure that will make most of the formatting decisions, and keep the SSRS work in the report designer as simple as possible.
The following text is from the original question. I have an SSRS report which contains 2 tablixes. Each tablix has a different dataset coming from separate stored procedures. Currently, everything works good; the user selects one customer (customer A) to display the one page report for; data for customer A for the 1st tablix may contain 7 rows, and data for customer A for the 2nd tablix may contain 4 rows. User prints report, then chooses customer B which may have a different number of rows for each tablix.
I would like to give the user the option to select "All Customers" to display the report for all customers, one page per customer and I currently do not perceive that there is a way to paginate the report; one page per customer. When I pass in "All Customers" to the 2 stored procedures I get all of the correct data back; sorted by customer; so I can do some sort of page break on a row group on the customer name column, but I have 2 tablixes of data.
Hi All,
How do I input a large text page (notepad) into a SQL column. Or assign a pointer to the data. I've tried to use BOL (writetext) and to no avail, I guess I'm missing something. I'm just using EM and Query analyzer. I thought this should be easy. Image data should work the same way.
TIA,
Dave
Hello:
The purchased-application mssql 6.5, sp 4 that I am working on has one large table has 13m illion. It the largest table considering thenextlatgest table is only1.75 million rows.
Thew vnedor has made a change to this largest table in recommending changing a data type -- char to varchar. To make this change easier to do,
I want to "archive" older data not necessary for the current year or current processing to another table.
What is the best way to do this archiving?
Any information you can provide will be greatly appreciated. Thanks.
