Replication - General Question
Jun 15, 2007
I have a database that I need to have replicated to another server - the server I need it replicated too already has a copy of the database. Is it possible to set up a replication and when replicating - keep it from the copy that is there? The copy that is there has a column that isn't set up on the main one.
Thanks!

Hi All... We're developing an asp.net based project. We plan to deploy it across multiple servers running in an NLB environment. That is NLB via hardware or software - we generally leave that decision up to our customer. Different from prior projects we've done, this application will rely on a SQL Server 2005 database. With the NLB, we essentially install our application many times across multiple servers. As hits come in from clients, they'll get directed to one server or another by whatever NLB technique is being used. The applicaiton generally doesnt care which server is hit.
But what about the database? What's a typical or best architecture to employ? Should each server have an instance of SQL Server and then somehow through replication they all keep each other updated? Or should each of the servers hit one lonely instance of SQL Server and it somehow keeps some other backup instance updated? I think the first approach seems to make more sense from a load balancing point of view, but depending on how many servers there are, it could get quite complicated.
Again, we're in the early stages so we really havent done much research on this yet. Any tips would be appreciated. Any good white papers out there?
Thanks! -- Curt

I am in a position to replicate to more than 100 subscribers. I have the distributor running on another machine - that is not on the same publisher machine. I sometimes experience some problems - like whenever I reboot this distributor server - not all the replication jobs start - they wait on worker threads.
To avoid this situation - one of my friends suggested to have another distibutor for the same publisher. I want to know if the publisher to distributor is a one- one relation or I can have multiple distributors for the same publisher.
I have this replication in SQL 2000. Is this any way different in SQL 2005.
Thanks,
Sam.

The following is my code. What I am trying to do is find all the students a teacher as assessed during a give time. Then find out which assessment was done the most recently. After that I will then be aggregating those results. I have never written any pl/sql or T-SQL... heck I don't even know what to call it!The first sql command is doing what I want it to. I can only assume the cursor is working correctly. Any help would be greatly appreciated.BryanALTER procedure Domain@UserID numeric,@StartDate datetime,@EndDate datetime
AS-- Variable DeclerationDECLARE @SessionID varchar(1000)DECLARE @EachSessionID numeric
--Cursor to find all Children that the teacher has assessed for the given timeDECLARE ChildID_cursor CURSORFORSELECT DISTINCT childID FROM capsessionWHERE userid = @UserIDAND sessiondate BETWEEN @StartDate AND @EndDate-- looping through all Children to find there most recent assessment.OPEN ChildID_cursorDECLARE @ChildID numeric FETCH NEXT FROM ChildID_cursor INTO @ChildIDWHILE (@@FETCH_STATUS <> -1)BEGIN IF (@@FETCH_STATUS <> -2) BEGIN DECLARE SessionID_cursor CURSOR FOR SELECT TOP 1 CAPSessionID FROM CapSession WHERE (ChildID = @ChildID) AND (SessionDate BETWEEN @StartDate AND @EndDate) ORDER BY SessionDate DESC END FETCH NEXT FROM ChildID_cursor INTO @ChildIDENDCLOSE ChildID_cursor
OPEN SessionID_cursorFETCH NEXT FROM SessionID_cursor into @EachSessionID SET @SessionID = ''WHILE (@@FETCH_STATUS <> -1)BEGIN IF (@@FETCH_STATUS <> -2) BEGIN SET @SessionID = @SessionID + @EachSessionID+ ',' END FETCH NEXT FROM ChildID_cursor INTO @ChildIDENDCLOSE SessionID_cursorRETURN @EachSessionID

Hello everyone,
as you might have seen, I'm a total newbie to this Site and M$ SQL.
I browsed the forum to see if there are already matching answers to my question, with no success.
My question:
As a MySQL & PHP user I ask myself if there is a possibility to use M$ SQL the way I use MySQL and PHP!?
Is there a way to generate dynamic websites with M$ SQL 2000 and a webserver running PHP sources?
A brief yes or no would really help me, if you have any links or resources on this topic, I'd be glad to hear about it.
Thanks
Tom

Hi! How do you query an entire db for a value?
I know how to do table queries from the SQL Analyzer, but not a full DB search.
Like, if I wanted to find a value '137.51 in a DB, what would I use?
Many thanks!

Before I go into specifics, this is my problem. I've have a tablethat gets updated with large amounts of data on a monthly basis.Sometimes (rarely) identical rows of data are on one months import thatalready exist from the previous month. I can identify these rows from acombination of two fields (sampleID and testname).My question is this. Would it be an appropriate 'fix' if I created anew 'formula' field on the table comprising of a concatentation ofthese two fields and then made that an index field (no duplicates)? Myguess would be that if we then tried to import a record with a sampleIDand testname that already existed, then the import for that recordwould simply fail.Would this work? Is there a better way? My background is more withAccess so apologies if I'm not using the right terminology.Simon Harris

I have a general question about transactions and commands that are replicated in a Transactional replication.
My screen shot says:
A total of 5 transaction(s) with 85 command(s) were delivered.
I know what a transaction is, but what is a command?
I am assuming a transaction is
begintrans
committrans, correct?

I am currently upgrading my companies database from 6.5 to 2000. Including the replication. I am curious about something. Currently we are using the commands in 6.5 to do the replication instead of stored procedures. (except for one table that requires custome filters). When I reestablished replication on 2000, the default is to create stored procs on the subscribers to hande the replication. (sp_MSins_tablename). My question whether anybody knows why it defaults to using sp's? Is there a reason or is that just the way it is. I want to know if using sp's is better than just sing the commands before I change my setup.
Thanks for any responses.

Hello,
Can someone please answer the following questions:
1) Am I correct that SSRS 2005 can access a remote data source on SQL Server 2000? (this one I'm pretty sure about). I'm also trying to determine whether I can move up to SSRS 2008 when it is released and keep running all the same report types against SQL 2000.
2) Where is the bulk of the reporting services calculations performed (e.g. NOT the database query itself)? The Reporter Server? Or the Reporter Server Database?
3) Is it advisable to have the Report Server and Report Server Database on the same server? How do people typically handle this?
4) Is it advisable to have the Report Server and the Datasource database on the same server?
Thanks!
Michael

I have a website. It is a SAS Site. It has a structure similar to
tbClient (ID, Username, password)
tbData (ID, ClientID, info)
tbDatax(ID, tbDataID, info)
tbDatay(ID, tbDataXID, info)
This is a reporting nightmare for me. I Ihave a sollution, but i was wondering if SRS has an out of the box sollution or if anyone knows of an out of the box sollution.
It is a reporting nightmare because clients want to be able to create reports out of the system, but I can't let them see other clients data.
My sollution is give them a username CLientA
They log into The database with CLientA login
I have views that mask the data by enforcing all of the relationships through the view.
create view vutbDatax as
Select tbDatax.*
from tbDataX
Inner Join tbData on tbData.ID = tbDataX.tbDataID
Inner Join tbClient on tbClient.ID = tbDataX.ClientID
where tbCLient.Username = User
User is a Database function that returns me the Username they logged into the database as.
Imagine doing that for 100 views. And managing the security on it. I have done it and it is in the process of testing right now but Does anyone have a better sollution.

Hi, I've got the query below which works as needed, but it performs the same inner select twice at present. What is the best way of eliminating the second evaluation of the inner select statement?
SELECT TOP 1 condition FROM
(SELECT condition, COUNT(condition) AS total FROM [JCM].[dbo].[jcmresults] GROUP BY condition)
WHERE total = (SELECT MIN(total) FROM
(SELECT condition, COUNT(condition) AS total FROM [JCM].[dbo].[jcmresults] GROUP BY condition))
Thanks,

I have a website that is probably going to hold a sizable amount of data. The data will be specific to groups of users based on login credentials. Would it be more efficient to create a whole new database for each group of users, or create new tables for the groups in the existing database?
Any thoughts on the topic would be appreciated.
Thanks

Hello.
I'm running into a rather intermittent problem when a search query is run on an ASP.Net web application.
The error is 'General Network Error' Check your Network Documentation...
As I said, it doesn't happen everytime which leads me to beleive that there is a problem with the database connection
There's probably no more than 50-60 max users hitting the app at any one time.
Anybody familiar with this?

Hi all,
I'm new to ASP2.0 development (not new to programming though) and have been grappling with general paradigm questions.
So far, I'm using a SQL database to store my applications data. On UI front, I've been using the SQLDataSource in combination with a gridview control. VS2005 thus far has been really easy to use when it comes to these controls. However, I see myself having to know knowledge of the database in UI layer which screams as a classical mistake.
The right thing to do seems to be to have an intermediate layer, an object model, abstracting the database. However, if I do create an object model representing tables in my database and then expose these to the UI layer, I lose the ability to easily display data in my gridview (i will no longer be using a sqldatasource.
So, after much run around my question is this, what is the preferred paradigm when programming applications for ASP.NET 2.0 and can you still use the nicities offered by VS2005?
Thanks

Over the course of many weeks the frequency of the following error has been occurring. I have been trouble shooting this problem since I started with the company some 3 weeks ago and I am just stumped.
I'm running SQL7/SP3 on NT4 with current SPs and hotfixes. My default library is NamedPipes with an alias allowed for TCP/IP.
Any help or leads would be appreciated. I've checked for everything the MS KB suggests and it still hasn't resolved my problem!
example of the error:
Microsoft OLE DB Provider for SQL Server error '80004005'
[DBMSSOCN]General network error. Check your network documentation.
/dir/file.asp, line 29
THANKS!

Hi
Would you say that it's ok for a web site code to make ALL of it's access to a db through SP and views? And I mean everything including inserting new records and updating others with no use with SQL in the code.
The advantage would be very strict control over the access, but in order to achieve this it would take many many SP and views to cover all types of actions, can you think about a disadvantage except all the work creating those SP?? what about the server resources and performance? how demanding it would be?
Thanks,
Inon.

let me explain the scenario first
say table1 has columns col1, col2 and col3
where col1 and col2 together is PK
and col1 is same for for entire table and col2 is unique (well some may get doubt why to use col+col2 for pk when col2 alone is unique, to clarify this doubt, we have two dbs where in one db col1 does not repeat (in other words there are multiple dbs created based on this col1) and in other db it repeats (all dbs merged together))
sample data
col1--col2
==========
a--1
a--2
a--3
a--4
a--5
a--6
a--7
.
.
. so on
now my question, does both of the below queries takes same time
ex1:
select * from tabel1
select * from tabel1 where col1 = 'a'
in other words, does WHERE clause has any effect in performance when the column used in the query will always the same value with what it is compared?
does it has any effect when i join also?
ex2:
select a.*
from tabel1
inner join tabel2 a
on a.col1 = b.col1
and a.col2 = b.col2
select a.*
from tabel1
inner join tabel2 a
on a.col2 = b.col2 -- note: col1 is not used in join
and please explain how it is same/different

This is a very general quastion.....I regularily take data extracts from a SQL server database drop them inexcel and run a macro on the data.The macro does nothing more complicated than loops, addition,subtraction and remeber the changing value of a declared variable.It works perfectly, but is constrained by the number of rows in excel.I want to investigate the possibilty doing the calculations in the SQLtables. (All the data is contained within one table).What is the best way to approach this problem.i.e. can I get my excel macro to link to the Table and if not, whatother solutions are avialable to me.Regards,Ciarán
