I'm working on a search engine right now, and I am querying out a set amount of information at one time. How can I grab the last row count of a query, and use that as a starting point, or index when a "Next 100" is pressed. For instance, a person searches through a user table, but only wants 25 users at a time. So the beginning index is 0 to 25. In my query, I have "SELECT TOP 25 from users", but now when the person searching want's to move to the next 25 users, so the index would be 26 to 50, how can I hold the last row displayed? It gets a little more complex also, if a user is searching by last name, the rows will be staggered. Is there a SQL function which will grab the number of the last row displayed? I've looked through the SQL Book, and was unable to find a function that does this, or anything close to it. I hope I made sense of this question, if you need more information, email me and I will try to clarify. Thank you for any information or hints.
The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.
Here is a test code snippet:
--Test Count/Count subquery
declare @Date datetime
set @date = '8/15/2007'
select -- count returns unit data Count(substring(m.PTNumber,3,3)) as PTCnt, -- count returns total for all units
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt, -- attempting to calculate the percent by PTCnt/TotalCnt returns 0 (Count(substring(m.PTNumber,3,3)) /
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date)) as AUPct -- main select
from tblVGD1_Master m
left join tblVGD1_ClassIII v on m.SlotNum_ID = v.SlotNum_ID
Where left(m.PTNumber,2) = 'PT' and m.Denom_ID <> 9

If I have say 20 records of sales employees, for example, how can I get the top 3 locations for $$$sales for EACH employee? Each employee can have multiple locations where they have sold(let's say up to 50). I only want the names of the top 3 locations. The closest I can get is filtering the dataset by a HAVING clause > a dollar amount but this still gives me between 3 - 12 records for each plus I have to literally enter each salesperson's number as it stands now. Is this a loop or a cursor? Thanks.

I have a new computer, clean, I installed WinXP, and I want to connect a SQL Server (other computer in the same network) For this I installed the client tools from SQL SERVER 2000 kit. Ok. When I try to connect to the server, I can't connect through "trusted connection", only whit user name and password. I mention that I set the sql server in mixed mode autentification.
When I try to connect from other computer (my laptop, or other computer from this network) I can connect both types of connection: trusted and with
sa (for example)
The question is:
How I can set up a "trusted connection" at SQL Server?
The computer is completely new, clean and has win xp with sp2.

i need to programmatically obtain and the process constraintinformation. the problem with the output from sp_helpconstraint isthat it outputs two resultsets. (the 2nd resultset is exactly what ineed though)as far as i know i can't stick this output into a temp table to thenprocess with cursors or anything like that. i'm trying to directlyaccess all kinds of sytem tables but not getting the complete info thatthe 2nd resultset that sp_helpconstraints offers.(E.g. sp_helpindex is more useful as it outputs only one resultset ofinformation so i could programmatically use that output to do what ineed to do)any suggestions? thanks.
i need to programmatically obtain and process constraint keyinformation. the problem with the output from sp_helpconstraint isthat it outputs 2, and sometimes 3 resultsets. (the 2ndresultset/constraint_keys is exactly what i need however)because the resultsets vary in output format, i cannot programmaticallyuse the output to process in my DB proc. its essentially useless tome. i can only suppress the 1st resultset (with tablename info), andcannot suppress the occasional 3rd resultset (that has referencingforeign key info).i've tried to directly access all kinds of sytem tables but i'm notgetting the complete info that the 2nd resultset thatsp_helpconstraints offers.any suggestions? thanks.

I know the default data path on a SQL7 server is defined in theregistry key SQLDataPath. I want to be able to determine the defaultdata path in a VB.NET application on the local machine and remotemachines. Is using the Registry Class the best way to do that or isthere a SQL command that can tell me? I have read about xp_regread butI can't find it documented anywhere and I do not know what parameterlist it is expecting. I thought this path may be in an InformationSchema view, but I can't find it.Thanks for any help.
I have created a linked server that connects to "mpp" file, and it connects and opens successfuly returning a list of tables that exists in the linked server to the mpp file.
But the problem i am facing now that whne i write a select statment to get data from the tables in this linked server
select * from linktompp.testmpp.dbo.tasks
such that linktompp is the linked server name
testmpp is the catalog name
tasks is the table name i need to select data from
it shows an error that says
"Could not obtain a required interface from OLE DB provider 'Microsoft.Project.OleDB.11.0'."

I see others having this problem when trying to run a query across a link from 2005 to a 2000 server. But we are already running SP4 on our 2000 server. What gives?

We recently bought a new (sql) database server with 8 gb ram. I started moving the databases from our older 2005-sql to the new one. Everything goes well, except...
Some steps in our jobs do a truncate table of a delete from... When the job is running and it reaches the step where the truncation/deleting starts, it stops its execution and gives the following error :
Code Snippet
The instance of the SQL Server Database Engine cannot obtain a LOCK resource at this time. Rerun your statement when there are fewer active users. Ask the database administrator to check the lock and memory configuration for this instance, or to check for long-running transactions. [SQLSTATE HY000] (Error 1204). The step failed.
When I try to execute the procedure that does the truncation manually, it works perfect. Do you guys have an idea on what the cause of this error might be ?
Thanks a lot in advance !
