I want to select data from a table with 5.000.000 rows. It's very slowly. Do you now, how I can select only a XY number of rows? I can't use TOP in select query. User see only 20-30 rows on his page, but he can use page_up, page_down. Is possible to something as lazy load?

I have a report that calls a stored procedure. I want to display the number of records that the stored procedure returned. I can't seem to find an expression that will do this. Is there an expression that will display the record count for a dataset?

hello,
i have a stored procedure SELECT CommentID, UserName, CommentingDate
FROM Comm
WHERE PictureID = @PictureID
ORDER BY CommentingDate DESC
witch shows me the users who commented a Picture with PictureID = x
I need to add two rows at that stored procedure, one to show the number of total comments at that picutre (like counting the number of rows returned) and the second to show count the DISTINCT users who commented that picture
I tryied with COUNT but i have to use GROUP BY and i don't think this is good...
I hope you understand... please help me,
thanks
Is there a way to extend the number of rows that will be returned so that Reporting services doesn't display such a large number of pages for the users to page through? It would be easier for them to "wheel mouse" through a long page on the screen.
Anyone out there have any thoughts on how this might be accomplished?
Thanks!

I have a conditional split in an SSIS package - one split is where if rows are returned according to a specific rule, then insert those rows into to a Recordset Destinationm which points to a variable of Object type.
How I can use this variable to email fellow users. For example, what I would like is if ANY rows are returned to the Object variable (1 or more), then I would like to execute an email SP that we have on our server.
when I execute the line:
reader = comm.ExecuteReader();
Is there a way to get a count of the number of records returned (the query is a SELECT with no count in it)? I want to vary the display of the results set based on the number of records returned.
For example if no records are returned I want it to display nothing, if one, I want the header to be in the singular, but if more than one record is returned, I want it to display the header in plural form.
Here is my code snippet with further explanation of what I am trying to do:int Inumber = 0;foreach (string item in menuHeaders)
{string title = menuHeaders[Inumber];
sp.Value = menuHeaders[Inumber];
Inumber++;
conn.Open();reader = comm.ExecuteReader(CommandBehavior.CloseConnection);
//Get the culture property of the thread.CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
//Create TextInfo object.TextInfo textInfo = cultureInfo.TextInfo;
// WHAT I AM TRYING TO DO....... Here I would like to wrap this with an if statement, if Records returned by the reader are 0, skip while loop and header display
// If one, then display in singular and if 2 add an s to the title. Convert to title case and display.content.Text += "<H3>" + textInfo.ToTitleCase(title) + "</H3>";while (reader.Read())
{
content.Text += "<a href='" + reader["website"] + "'>" + reader["f_name"] + reader["l_name"] + "</a>"+ ", " +reader["organization"]+"<br />";
}
//Close the connection.
reader.Close();
conn.Close();
}

Hi,
I'm using SqlDataSource control.
Is there a way to know how many records a query has returned?
In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

I am using SQLExecute() in C++ code.
My query is "select * from Revoked_users"?
How I will come to know the no. of rows returned by SQLExecute() ?
The code below returns 0 rows. The statement is intended as generic statement that would return all records between a particular start and end date and on each date only between a specific start and end time. It works perfectly if the end date is greater than the start date.
Unfortunately, if the start and end dates are equal (i.e, return all records on that one date and only between the specified start and end times) then no records are returned.
BTW, it is also looking for matching datetimes in two tables and there really is matching data in the two tables for that particular date and times.
Can anybody help resolve this?

When querying a bit field, I am encountering a problem with MS SQLServer returning a larger number of records for a table than theactual number of records that exist within that table.For example, my customer table has 1 million unique records, so theresults of the following query are as such:select count(customer_nbr) from customer = 1,000,000There is bit field in the customer table that denotes whether acustomer has placed an order with us called. That flag is calledorder_flagIf I run the following query:select count(customer_nbr) from customer where order_flag = 1The result is 3,000,000 records.There is no logical way that this is possible, as my table onlycontains 1,000,000 unique records and the number of customers with anorder should be a subset of this.If a run the above query with a distinct before customer number, I getthe results I want:select count(distinct customer_nbr) from customer where order_flag = 1600,000 records.So while I can get to the answer I want, I have no idea why I amreturning incorrect values if I don't select distinct.Can anyone help? I checked microsoft support and message boards buthaven't seen anything.I should note that the bit field is indexed.I am not sure if that isthe problem or not.
View 1 Replies View RelatedHello and thank you taking a moment. I have created a simple login page where the user will pass credentials. I have a sqldatasource that will query a database to see if the user exists. What I would like to do is have the user click a button after entering their credentials. When the button is clicked I would like the SqlDatasource SelectCommand to fire and if there are rows returned then redirect the user to a new page.
I know I can do this with ADO and a datareader with the HasRows property. But what I would eventually like to do is cache the data and then bind the cached data to a control(like a dataview) on the page the user is redirected to. If anyone can tell me how to get the Select command to fire on a button click I would be eternally grateful. Any help will be greatly appreciated.

The following query only brings back too much data in the table - there are duplicates and the lab it shows is wrong.
The problem is:
AND a.calLab = f.ID
in the Where statement.
Some equipment does not need calibration, so, a.calDueDate = 0 AND a.calLab would be NULL or 0.
tblLabs ID field has 1 - 18 (Labs) - no 0 and of course no null
I need to get the rest of the data.
Any suggestions?

Is there a way to limit the number of rows returned by a SqlDataReader? I know I can do it by modifying the Stored Procedure, but I'd rather not modify a procedure that is used in multiple apps. I'm hoping there is something easy like setting SqlDataReader.RowsReturned = 100, but that might be too easy to hope for.

Any ideas on why it would be behaving this way?
As a part of my unpaid internship, I am creating a ASP.NET interface for a MS SQL Server 2000. The table I am having problems with has over 750,000 rows by 26 columns. There isn't a primary key. It stores a transaction dump from another primitive Database server.
Problem:
When perform a query I get one set of results. I run the same query again after a short wait and the rows returned are in a different order. The majority of the rows returned are the same ones returned in the previous query. Only, some rows may be missing and the order may change.
I really wasn't surprised by some duplicate rows. I am confused why they are showing up in a different order and the above mentioned inconsistancy in results.
I thought I was having problems with my Repeater Control; however, SQL Query Analyzer returns the same results.
Question:
What is causing the problem?
Given the following results:
col0 col1 col2
THY 2,265,850 31
VIE 1,474,994 20
RID 1,221,800 17
ACC 1,124,335 15
FEI 445,184 6
DIR 433,783 6
ROM 324,365 4
What is the best way in a query to get the rank of the returned rows by either col1 or col2. In other words who's the number 1,2,3 etc...
total count col0 = 7
total col1 = 7,290,310
total col2 (would eqaul 100%)= 99%
Looking for a mathmatical solution to this any help would be appreciated.
Hi,
I have a problem that I would like help with.
I have to write an SQL Server 2000 stored procedure that returns rows from a table (a SELECT with an ORDER BY). A front end system calls the stored procedure and displays the returned rows. If there is more than one screen's worth of data (ie more than 20 rows returned from the table) then there is a requirement that the stored procedure only returns the rows for the screen ie, for screen 1 I need to return rows 1-20, for screen2 I need to return rows 21-40, screen 3 = rows 41-60.
The screen number will be passed into the stored procedure so I can work out what rows to return, the only problem is how can I tell SQL Server to only select the required rows (ie, say rows 21 to 40 from the returned rows). I can't see any arguments that allow selective rows to be returned (apart from TOP).
Any ideas??
Regards,
Chris
Hello, I have a question on sql stored procedures.
I have such a procedure, which returnes me rows with ID-s.
Then in my asp.net page I make from that Id-s a string like
SELECT * FROM [eai.Documents] WHERE CategoryId=11 OR CategoryId=16 OR CategoryId=18.
My question is: Can I do the same in my stored procedure? (without sending it to page)
Here is it:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[eai.GetSubCategoriesById]
(
@Id int
)
AS
declare @path varchar(100);
SELECT @path=Path FROM [eai.FileCategories] WHERE Id = @Id;
SELECT Id, ParentCategoryId, Name, NumActiveAds FROM [eai.FileCategories]
WHERE Path LIKE @Path + '%'
ORDER BY Path
fileCategories table: (for information)Here is the screenshot of the table (10 kb )http://eai.w2o.ru/screen1.gif
Thank you

How is the best way to check for No rows returned from a Select statement in a Stored Proc? I have see this:
Code Snippet
Declare @res int
set @res = NULL
Select @res = dbKeyColumn
From aTable
If @res is null
then no rows returned.
Surely there is a better way??
Thanks.
I'm using a simple data flow to extract rows from a table (using a SQL query) and put them in a flat file. If the query returns no rows, I don't want a file to be created. Right now it creates a file with the headers (since I do want the headers if there is data).
Any one know how to do this?

In MySQL we use "SELECT (....) LIMIT 0, 10" to only return the first 0 to 10 records. Alternatively we could do "LIMIT 10, 20" to return the 10th to 20th records.
What's the equivilent of this in SQL Server?
Thanks
This should be a simple solution, but it has been a long time since I've done any query writing (mostly in Oracle) and I am stumped, so here goes:
We are in the process of converting Access database to MSSQL with web form front ends.
I have a table, all columns are nullable, and want users to be able to query from a form, which has a field for each column and defaults to a % wild card for the entered value.
I want the users to be able to put any string in any field, and have it return each row that matches that, including rows with null values in the other columns, but not the column with the entered criteria.
Here is a sample of the data:
Code:
SQL> select * from test;
COL1 COL2 COL3 COL4
----- ----- ----- -----
this is a test
this is not test
this is not
this is test too
is test too
is too
is too
7 rows selected.
Now, if I have this SQL run, it will return only rows that have no nulls in any columns:
Code:
select
col1,
col2,
col3,
col4from test
where
col1 like'th%'
and col2 like '%'
and col3 like '%'
and col4 like '%';
COL1 COL2 COL3 COL4
----- ----- ----- -----
this is a test
this is not test
this is test too
Now, if I use an OR clause for each column, this mostly works, but the trouble is it will also return rows with null values for the field that has criteria entered in it:
Code:
select
col1,
col2,
col3,
col4from test
where
(col1 like'th%' OR col1 is null)
and (col2 like '%' OR col2 is null)
and (col3 like '%' OR col3 is null)
and (col4 like '%' OR col4 is null);
COL1 COL2 COL3 COL4
----- ----- ----- -----
this is a test
this is not test
this is not
this is test too
is test too
is too
is too
The idea is to only select the first 4 rows in the above example.
I was playing with ISNULL in the select clause, but all it does is substitute a string for a null, and I think CASE will do the same thing.
Is there a way I can write this query so it will return rows with NULL values in any column, except the one(column) that has user entered criteria in it?
