How To: Retrieve A Limited Number Of Records From A Record Set
Apr 24, 2008I€™m working on a database project that will ultimately contain millions of records for each lot. In addition, each lot will have up to 96 corresponding serial number records.
I would like to add a SQL parameter that would tell the database engine to only return X number of records.
For Example:
If table TBL_LOTS contains one million records I would like to limit the return set to 100 for example.
What would I need to add to the SQL command to below to restrict the data set to the first 100 records in the set of one million?
SELECT [LOT NUMBER]
FROM TBL_LOTS
WHERE [STATMENTS]

Stored Proc Returning Dataset && Number Of Records Not Working
Jul 7, 2004Hi
I've created a sproc in SQL2000 that returns a dataset from a temp table & the number of records it's returning as an output parameter, although I can't seem to retrieve the value it's returning in asp.net although I get the dataset ok.
This is my sproc
create procedure return_data_and_value
@return int output
as
set nocount on
...
...
select * from #Table
select @return = count(*) from #Table
drop table #Table
go
This is asp.net code
Dim nRecords as Int32
Dim cmd As SqlCommand = New SqlCommand("return_data_and_value", conn)
cmd.CommandType = CommandType.StoredProcedure
Dim prm As SqlParameter = New SqlParameter("@return", SqlDbType.Int)
prm.Direction = ParameterDirection.Output
cmd.Parameters.Add(prm)
conn.Open()

Flat File Data Flow Source Returning Limited Rows
Jan 14, 2008
All,
I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!

May 5, 2006Using System.Data.SqlClient is there a limit to the number of connections an application can have to a SQLMobile dB?
If
you have a look at the url below, it says "A device can only have a
small number of connections to an instance of SQL Server at any time"
Does this mean 2, or 8 or what?
Should a app try to use only 1 connection throughout, or can we get away with 2-3?
Is this the same on WM5.0/PPP2003?

Inserting Records With Limited Privileges
Jul 23, 2005I am trying to insert records via ASP, with a user that has only writeaccess to the table (db_datawriter, db_denydatareader).That way, if the server is ever compromised, the access informationstored in the source code's connection string will not allow anybody toactually read the database.The problem is that I would like to use ADO methods to insert the data(to prevent SQL injections), but I can't seem to get the rightconnection. It works in plain SQL, but I'd rather not use it.My current code looks like this:connection="Provider=SQLOLEDB.1;User ID=DBwriter;Password=XXX;DataSource=MYSERVER;Initial Catalog=MYDB;"set conn=server.createobject("ADODB.Connection")conn.mode=2 ' adModeWriteconn.open connectionSet rs = Server.CreateObject ("ADODB.Recordset")rs.Open "MYTABLE", conn, adOpenKeySet, adLockPessimistic, adCmdTablers.AddNewrs.Fields("testfield") = "TESTDATA"rs.UpdateAnd the error I get is:Microsoft OLE DB Provider for SQL Server (0x80040E09)SELECT permission denied on object 'MYTABLE', database 'MYDB', owner'dbo'.(If I use a User with read privileges in the connection stringeverything works fine.)

Analysis :: SSAS (BISM) 2014 Full Processing Number Of Threads Are Limited
Jul 6, 2015I have been tasked with processing a large tabular cube using SQL AS 2014 (with latest CUs).The three Fact tables having 1.2 billion rows (in each table)  have been divided into 30 vertical partitions to aid in parallel processing. So around 40 million rows per partition.
Using SQL Profiler to monitor the Row counts (IntegerData) of records processed seems to max out around 2 million rows per minute, then tapers down to about 200k /minute.
The processing is taking over 14 hours and I need to get it lower if possible. The server has 48 cores (2.66MHz) and over 1TB RAM installed. But I really don't ever see CPU exceed 20% having a maximum of 206 threads running on the instance msmdvr.exe
Available RAM is always at least 30% (or 300GB).
I have increased the Vertipaq MIN/MAX 60%/80%
I have increased the OLAP / Processing / Max Thread Pool Min 500 and Max to 1000.
The connection properties have been increased to allow 100 connections, the majority of the processing consumes about 92 connections for the 90 large partition views for the facts.
What can be done to increased the server resource utilization and decrease processing times?

Returning A Value That Has The Smallest Number Of Instances In A Table
Nov 5, 2007
Hi
Please help! I'm really stuck. I have a table (AssessorAllocations) that stores the data of students who have submitted assessments for marking by an Assessor. Each time an assessment is submitted by a student my program must determine which Assessor has the smallest workload and then assign the current assessment to that Assessor. My problem is how do I determine which Assessor has the smallest number of assessments assigned to him/her.
The table columns are:
AssessorRegistrationNo
LearnerRegistrationNo
QualficationName
SubjectName
AssessmentName
DateAssigned
Marked
DateMarked
Price
So I'm looking for something like this:
Select AssessorRegistrationNo from AssessorAllocations where {Select the Assessor who has the smallest number of AssessmentNames assigned to him/her where Marked='0' and DateAssigned<>''}
Thanks

Returning Middle Records
Dec 7, 2006I'm writing a page that will return data from my database to the user based on their search paramaters, over several pages with 20 matching records showing per page, and a next button on the bottom. Similar to the format of any search engine.
However, I'd like to write this into the query, and I'm not sure how I would go about doing so. For example:
"SELECT TOP 20 to 40 * FROM Northwind"
Hopefully this makes sense. Is there any way of doing this?

Returning A Specified Range Of Records
Jul 14, 2005Hi,
I have a SQL question which I suspect is very easy to answer but can't seem to find one for.
I have a table which contains about 500 records. i would like to display these records on a web page, but paginated, showing only 20 records per page. I have in the past returned a recordset containing all the records and paginated programmatically in ASP. In this instance I would like to be able to pass an upper and lower bound into my stored proc and return only those records I want to display. So on page 4 I would want to display only records 61-80. I can pass in the upper and lower bound to the SP as parameters but is there some T-SQL i can use to return this range of records only.
So, the SP would for example accept the parameters
@Upperbound = 80
@Lowerbound = 61
and would return a recordset of 20 records being the 61st thru 80th record from the queried table.
Thanks for the help
Guy
PS. I asked someone at work and they suggested using OFFSET and LIMIT. It seems to me as if these are only available in PostgreSQL or MySQL and not T-SQL. I guess I am looking for an equivalent I can use with SQL Server.

Help With Returning A Certain # Of Records From A View.
Jul 20, 2005I have a view that will return say 5000 records when I do a simpleselect query on that view like.select *from vw_test_viewHow can I set up my query to only return a certain # of records, saythe first 300?Here is what is going on, we have a large amount of data that returnsin a view and we need to work with all of it eventually, However wewant to do it in chunks. So my thoughts were as follows:1. To run a query to return X amount of the total data for us to workwith.2. Update these records with a flag in a table that the vw_test_viewfilters out.3. The next time I run the query to pull data from the view it willskip the records that I have already looked at (because of step 2) andpull the next X amount of records.Thanks in advance,Mike
View 3 Replies View RelatedReturning Billable Records.
May 15, 2008Hello -
I'm trying to write a select statement that will return only "billable" records.
A record is billable if:
- it is the only record for a Case (Case is an FKey ID column in my records table)
OR
- the last billable record for Case X has a DateTime > 24 hours before the record in question.
Getting records for the first condition is easy:
SELECT ID FROM Records r
LEFT OUTER JOIN Records r2 ON r2.[Case] = r.[Case]
WHERE r2.[Case] IS NULL
It's the second part I'm having trouble with.
UNION
SELECT ID FROM Records
JOIN ?
....
WHERE DATEDIFF(hh, r.DateTime, r2.DateTime) > 24 ??
I have to assume there can be any number of records for a case.

Returning Range Of Records In MSSQL
Jan 25, 2005Hi guys, I need to know if there is a way to select a range of records from a database. Kind of like using SELECT TOP 1000, but I need to be able to specify which records to return. So I imagine it would look like this:

Where this statement would return only records 2000 to 5000 of the returned results.
T-SQL (SS2K8) :: Returning Multiple TOP Records?
Jul 10, 2014Here is my setup: I have the following tables -
tblPerson - holds basic person data.
tblPersonHistorical - holds a dated snapshot of the fkPersonId, fkInstitutionId, and fkDepartmentId
tblWebUsers - holds login data specific to a web account, but not every person will have a web account
I want to allow my admins to search for users (persons) with web accounts. They need to be able to search by tblPerson.FirstName, tblPerson.LastName, tblInstitutions.Institution, and tblDepartments.Department. The only way a Person record is joined an Institution or Department record is through many -> many junction table tblPersonHistorical.
People place orders and make decisions in our system. Because people can change institutions and departments, we need an historical snapshot of where they worked at the time they placed an order or made a decision. Of course that means some folks will have multiple historical records. That all works fine.
So when an admin user wants to search for webusers, I only want to return data, if possible, from he most recent/current historical records. This is where I am getting bogged down. When I search for a specific webuser I simply do a TOP 1 and ORDER BY DateCreated DESC. That returns only the current historical record for that person/webuser.
But what if I want to return many different webusers, and only want the TOP 1 historical for each returned?
Straight TOP by itself won't do it.
GROUP BY by itself won't do it.
Returning Records Within Days Range
Oct 31, 2013This is a follow on from one of my earlier threads where I was trying to return one specific record. In this case I am trying to return multiple records for the same person ID and within a number of days range. Snapshot of my date with same PersonID:
PersonID Arrival_Date Leaving_Date ArrivalID
======== ============ ============ =========
123456 01/12/2012 01/12/2013 arr_56464
123456 10/12/2012 10/12/2013 arr_56474
123456 13/12/2012 13/12/2013 arr_56494
And from this I want to check if one record's leaving date of the record is within 7 days of another record's arrival date. I also want to return the record that had a leaving date within 7 days of the next arrival date.I understand that if I self join on personID with the data above I will get 9 rows, for each row I will get 3 matches, I am using INNER JOIN to join to the same table but with a different alias so I assume this is the self join I should be using.
But then how do I process this? I would want to say for record 1 check the leaving date is within 7 days of arrival date of any other record matching that PersonId but not ArrivalID, and return both records.From my snapahot of code I would eventually want to return:
PersonID Arrival_Date Leaving_Date ArrivalID
======== ============ ============ =========
123456 10/12/2012 10/12/2013 arr_56474
123456 13/12/2012 13/12/2013 arr_56494
But can't seem to get this using a self join query like this:
select a.PersonID, a.Leaving_date,a.Arrival_Date,a.arrivalID
from arrivals a INNER JOIN arrivals b
ON b.personID = a.personID
WHERE
a.arrivalid != b.arrivalid
and DATEDIFF(DD, b.[Leaving_date], a.[Arrival_Date]) <=7
and DATEDIFF(DD, b.[Leaving_date], a.[Arrival_Date]) >=0
