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 Users
SELECT T.rowid, T.userid, ISNULL(O.userid, 0)
FROM @table T
LEFT OUTER JOIN
(
SELECT DISTINCT(userid) FROM orders
)
AS O
ON O.userid = T.userid
AND 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)
I get 100 rows of result, i want to write a sql query similar to the one available in MySql database where in i can specify the starting row and number of rows of records i want,
something like,
select * from emp LIMIT 10,20
I want all the records from the 10th row to the 20th row.
This would be helpful for me to do paging in the front end , where is i can navigate to the next previous buttons and fetch the corresponding records.
I want to do something like in google, previous next screens.
So I am trying to limit the number of rows fetched from a query.
somethin like,
select * from emp where startRowNum=10 and NoOfRecords = 20
Im in the process of trying to teach myself SqlServer, comming from Oracle. How the heck do I get the equivlent of %ROWNUM pseudo-column in SqlServer? Top just isn't doing it for me. Oracle Example wrote: Select * from foo where foo%ROWNUM > 10 and foo%ROWNUM <20;
I need to be able to specify which column to sort by, BUT SQL 2000 does not allow me to
SELECT * FROM #TempTable WHERE ID > @FirstRec AND ID < @LastRec AND EmployerID = @EmployerID AND Job_no = @Job_no
ORDER BY @WHICHCOLUMN asc
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
"Sql server does not accept variables as part of sql"

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.
heres 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.
Hello To make pagination I would like to retrieve only the record from x to y ...I couldn't find how to do to in sql , I was thinking so if there is a way to do it with a sqldatasourceI make my request , put it in a sqldatasource and bind it to my datalistis there a way to "filter the sqldatasource ?" to make what I need ? Thx in advance ?
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.

hello, I have this project that I can't find it. let's say we have more than 100 000 rows in a table called table 1, so if we do: SELECT * FROM TABLE1 the result will be dispalying all the rows with a large scrollbar. But there's a new TSQL in SQL 2005 "ROW_COUNT" which will help to do the paging. so I have found the procedure but all I need now is to display NEXT and PREVIOUS button in the results in order to switch between the pages. So please any help, Thank you
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.
How do I write a query (using a union) suitable for paging I currently have a query which results from two queries combined by a union. It returns 3000 rows. I want to replace that query with one which returns only 50 rows from the relevant page [using ROW_NUMBER()]. Is there a way to do this with only 1 CTE or will I need to use two consecutive CTEs [the first get a union on the queries and the second to apply ROW_NUMBER()]. I can't see a way of doing it with only 1 CTE table. Alternatively is there a very efficient way to do it using derived tables?
I am getting incorrect results from my paging query, where the same results are being returned multiple times. Here are two queries I have found to bring the same results:select top 20 * from lookupdocuments_dbv where catname_cst='MyCategoryName' and (docid_cin not in (select top 620 docid_cin from lookupdocuments_dbv where catname_cst='MyCategoryName'))select top 20 * from lookupdocuments_dbv where catname_cst='MyCategoryName' and (docid_cin not in (select top 640 docid_cin from lookupdocuments_dbv where catname_cst='MyCategoryName'))When I remove the catname_cst where clause it brings back results properly (i.e. records 622-642 and 643-663). What is wrong with my where clause that is causing identical data to be returned?
I want to write query to implement paging in sql server ce 3.0. But it seems it does not support TOP or LIMIT keyword. Can someone suggest alternative way to write a custom paging query in sql server ce 3.0.
Hello, Why when I make a custom select statment with multiple tables, that when I test my query I'm shown the same rolls multiple times. When I make a custom query with just one table everything works just fine. I don't have any primary keys or restraints or whatever. SELECT * FROM table1, table2, table3 Does not work(shows each row multiple times) SELECT * FROM table1 works just fine (shows each row just one time) Thanks Steve
I am trying to allow a user the ability to search a database and select from various fields to search, such as Keywords and Filename. I tried building something like this: SELECT filenameFROM pictableWHERE (@searchby LIKE @searchwords) It allows me to enter the two varables (keywords and test), but returns no rows. If I simply replace @searchby with 'keywords' (ensuring no spelling errors), then I get a return of one row. So this works: SELECT filenameFROM pictableWHERE (keywords LIKE @searchwords) Can someone tell me what is going on? I have tried all sorts of quotes and parens to no avail. Thanks in advance.
I would like to run a simple select statement that pulls records from a table and returns a dataset. It is a dataset of teams. Then I want to populate a highly customized table with that dataset. The table will be a tournament bracket full of teams. Can I do something like this or do I have to display the dataset in a datagrid? Oh and this is a webmatrix project using MSDE. Anybody have any suggestions?
I am trying to SELECT data based on custom groups of that data. For example and in its simplest form:
SELECT COUNT(*) FROMdbo.People WHERE Current_Status = ‘A’ GROUP BY People_Code
The People_Code is the difficult part. The code represents the building that they work in. However, some buildings have multiple People_Codes. Kind of like multiple departments within a building.
For example:
Building NamePeople_CodeEmployee Count Building A617535 Building B985665 Building C529212 Building C529932 Building C419816 Building D326974 Building D781024 Building E25365
Each building has a main People_code which, for this example, could be any one of the codes for the building. For example: Main code for building C can be 5292 and for building D it can be 7810.
Applying a variation (which is what I cannot figure out) of the SELECT statement above to this table, the result set for Building C must be the combined employee count of all three People_codes and must be represented by the main code of 5292 as a single row. Building D would have a row using code 7810 but will combine the employee count of codes 7810 and 3269.
I built a conversion table that would match up the main code with all of its related codes but just couldn’t seem to make it dance the way I want it to.
People_CodeNameGroupNameGroupPeopleCode 6175Building ABuilding A6175 9856Building BBuilding B9856 5292Building CBuildingCGroup5292 5299Building C AnnexBuildingCGroup5292 4198Building C Floor6BuildingCGroup5292 Etc…
The whole query is much more involved than just the simple SELECT statement used here, but if I can get this to work, I’m sure I can apply it to the full query.
I want to add a custom column in a select statement that has a value to true or false based on other criteria.
SELECT [ID], [Name], [Description], [EmpID], [Employed] FROM [Employees]
Now, in the above example there is no [Employed] Column in my table but I want it to show true or false based on whether or not [EmpID] equals a certain value.
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?
SELECT ArticleID, ArticleTitle, ArticleDate, Published, PublishDate, PublishEndDateFROM UserArticlesWHERE (ArticleDate >= PublishDate) AND (ArticleDate <= PublishEndDate) When I use the above on a GridView I get nothing. Using SQL manager it works great. I don't know how to pass the value of the ArticleDate field as a default parameter or I think that's what I don't know how to do. I am trying to create a app that I can set the dates an article will appear on a page and then go away depending on the date. Thanks for any help!
Not sure if this is possible, but maybe. I have a table that contains a bunch of logs. I'm doing something like SELECT * FROM LOGS. The primary key in this table is LogID. I have another table that contains error messages. Each LogID could have multiple error messages associated with it. To get the error messages. When I perform my first select query listed above, I would like one of the columns to be populated with ALL the error messages for that particular LogID (SELECT * FROM ERRORS WHERE LogID = MyLogID). Any thoughts as to how I could accomplish such a daring feat?
When I first saw SqlCacheDependancy and Query Notifications I was really stoked. I began using these features in ASP.NET and some of this caching really sped up my site. However, I noticed some of my queries and results were not cached. This led me on a looonnnnggggg search of the internet for anything related to these topics.
Anyway, the problem is that the queries are very limited (http://msdn2.microsoft.com/en-us/library/ms181122.aspx) in what they can contain, no count(*), no top, no order by, etc etc. I understand that the reason for this may be that the Query Notifications is using some of the Indexed Views infrastructure and therefore has the same limitations. That's fine and all but caching the results of these types of queries is still very useful for a front page of a site where you want the top ten users by number of postings etc and if you use the TOP N clause to limit it to the top 10 then you lose the built in caching functionality because this query doesn't work with Query Notifications and the cache expires immediately.
Is there a way to just get notifications when the tables involved in a query changes? I don't need the granular level of the rowsets involved I just want to be notified if my table has changed so I can refresh my cached objects.
I know there is an overload for the constructor of the SqlCacheDependency class which takes the database and table names as parameters. MSDN states that this is for Sql Server 7 and 2000 but would this also work in my scenerio? I know it wouldn't be auto-magical but if I can still get pushed notifications of changes instead of polling for notifications I would believe this to be a more efficient solution.
Query Notifications are fantastic but the query limitations make real world usage a pain, it's like have a nice red sports car but finding out you can only drive it whens it is raining and then you can only make right turns.

in the acquireconnection method Using the below statment I can get a connection Object
oledbConnection = cmado.AcquireConnection(transaction) as OleDbConnection;
from the connection object I can get the connectionstring from the object by calling
oledbConnection.connectionstring() property which will have all the details like DataBase, UserName & other Inofrmation but there is no password Info.
How to get the password Information, I need that information since I will use that info to make OCI calls to fetch the data from the Oracle database in m,y custome source component.
