Forgive me if this is a stupid question.
How do you use a Server Side block cursor?
Lets say I have a db of 250,000 items and I want to retrieve the data 100 rows at a time.
How would I do this (using a block cursor, not in general)
thanks,
I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim

I have a VB6 application using classic ado (MDAC 2.8) for connecting ms sql 2000 server. Application uses a lot of server side cursors. Now I want to switch to ms sql 2005 server but I have noticed very serious performance problem. Sql profiler results of execution of following commands:
declare @p1 int
set @p1=180150131
declare @p3 int
set @p3=1
declare @p4 int
set @p4=16388
declare @p5 int
set @p5=22221
exec sp_cursoropen @p1 output,N' Select ... from ... where .... order by ...',@p3 output,@p4 output,@p5 output
select @p1, @p3, @p4, @p5
on sql server 2000:
CPU: 234
Reads: 82515
Writes: 136
Duration: 296
and on sql server 2005:
CPU: 4703
Reads: 678751
Writes: 1
Duration: 4867
Both databases are identical, the servers runs on the same machine (Pentium 2,8 Ghz, 2 GB RAM) with only one client connected. On forums I've read that Microsoft doesn't recommend using server side cursors on sql 2005 but is there any way to increase performance to some acceptable level?
thanks in advance

hi there,
to retrieve more then one record with a cursor we can use block cursor, so we have to set the cursor attribute SQL_ATTR_ROWSET_SIZE to some number...i am not getting any code example on this.
do anyone know this???
Hi All:
Can anyone point out what's wrong with the following script? I wanted to print all the LOGFILE names in all databases which are not in SIMPLE recovery model. Thanks in advance.

I have a Windows 2003 Server running IIS 6.0 and SQL Server 2005. I have just (Today) deployed the first ASP.NET application (developed in Visual Studio 2003 and, as such, dependent on .NET Framework 1.1) on this server and am getting HTTP Error 403 (You are not authorized to view this page). This ASP.NET application runs fine on another server that is configured with the OS=Windows Server 2003, IIS=6.0 but without SQL Server 2005 and without the .NET Framework version 2.0. I found in the IIS Application configuration (on the troublesome site) that my app (in the Default Web Site folder) was pointing to the version 2.0 aspnet_isapi.dll. All efforts to use aspnet_regiis to "re-align" my app with version 1.1 have been fruitless to eliminate the HTTP Error 403. I granted the NETWORK SERVICE account privledges to the wwwroot folder. At this point, I don't know if I have a Framework error or a privileges problem.
Please help.
Thanks,

I am trying to migrate from my current system, where I do merge replication from Windows Mobile devices running SQL Server CE 2.0 to a central database running SQL Server 2000 sp3a. I want eventually to move to a system running SQL Server 2005 CE replicating to a SQL Server 2005 back-end. But the transition will need to be gradual, and I may have to support both systems for a while until I can convert all clients from the old system to the new. I also need to do thorough testing.
So ... I'm trying to set up a test environment giving me the maximum possible flexibility to do my testing. Ideally, I'd like to set up SQL Server 2000 and SQL Server 2005 on a side-by-side basis, in a manner that would potentially allow mobile devices running both SQL Server CE 2.0 and SQL Server 2005 CE to sync with either back-end server.
Can someone provide me with guidance as what is possible to set up here? I know that SQL Server 2000 and 2005 can be installed side-by-side on the same server. It also appears that you can set up SQL Server 2000 so that EITHER SQL Server CE 2.0 OR SQL Server 2005 CE can sync with SQL Server 2000 (see www.microsoft.com/sql/editions/sqlmobile/connectivity-tools.mspx), but I don't know if it's possible for BOTH SQL Server CE 2.0 AND SQL Server 2005 CE to sync to the same SQL Server 2000. As for SQL Server 2005 ... it appears to be possible to set up SQL Server 2005 so that BOTH SQL Server CE 2.0 devices AND SQL Server 2005 CE devices can sync to the same SQL Server 2005 (see web page cited above). However, I don't know if it's possible to set up a SQL Server 2005 server installation in this manner while at the same time having a side-by-side SQL Server 2000 installation supporting any level of mobile merge replication.
HELP!!!!
Hello friends....
my question is as follows:
How do I send the data from the server side to the client side specifically in what format and what kind of connection do I use?
waiting for answers.....
will this create a separate instance?
Is there anything I need to be aware of?
Thank you.

Is there anywhere I can compare side by side between 2005 SQL Server and 2005 SQL Server express Edition?
I just found out that the express version does not have the database Copy feature (When you right clink on the database object -> Tasks ) !
I don't know about the evel version since I have not install yet. Any idea ?
Hi,
In Analysis Services there is an option to enforce a role either on the client side or the server side.
Can someone kindly guide what's the recommended approach and what's really the difference between the two options.
Thanks.
Hello!
I was wondering if I can install/run SQL 2008 and 2005 side by side with SQL 2005 being default instance. Any issues with that?
Thanks,

having installed 2005 first and installed 2000 with both types of reports going to one 2005 home. i would like to have separate homes
with reports going their respective homes. Do i have to first unstall
2005 and do a new installation with a different report and server than
2000. I would like to avoid this and just fine tune 2000 with the rsconfig.exe. Help me out please.

I have one standby server that I use for multiple production DB SQL Server 2000 servers. We are upgrading one of the production SQL Servers to 2005. I will install 2005 on my standby and run 2000 and 2005 side by side.
Is this okay? Are there any caveats specific to running 2000 and 2005 on the same standby server?
Thanks!

I plan to upgrade my server to SQL 2005. It is a rather old machine, but still ok with the recommended hardware requirements.
It runs Windows 2000 (SBS) server, which is also a PDC, DHCP, DNS, Exchange server (I stop here but the list is long), with SQL Server 2000 Standard Edition (one single named instance). Everything localized (Italian).
I upgraded the database in a development machine and it works perfectly.
I installed SQL 2005 Standard Edition (English locale) on the server (default instance, MSSQLSERVER), and I have run in a lot of troubles.
The problem seems to reside in the TCPIP network protocols. If I enable TCPIP in the 2005 Server Configuration Manager, the new instance (MSSQLSERVER) does not start (this prevented me from upgrading to SP1 until I realized the cause, disabled TCPIP protocol and was finally able to update).
If I understand correctly, the problem is that both instances, the old 2000 one and the new one, try to listen to 1433 port. I changed manually the port to 1434 in the Server Configuration Manager. The result is that both SQL servers work, but none is working ok. I have several applications accessing the server. The asp application works. The .NET aspx one doesn't.
A tipical error I get is:

I also tried to use named pipes on the 2005, but I was unable to access the SQL 2005 server instance from a network computer running the Management Studio. I need to have the new SQL server working besides the old one, for a short period, to evaluate in the production environment if the legacy hardware is actually ok to support it. Any ideas?
I'm rather new at working with SQL Server. I've installed 2005 onto my PC and I have 7.0 already. What I want to know is how do I import my packages from 7.0 into 2005?
Any help would be appreciated.
Thanks
Hi!
It is possibile to install SQL Server Compact Edition side-by-side on the same machine where SQL Server 2005 is already installed?
Thanks, Marco.
Background information:
I have been researching BOL, this forum, and the SQL Server help: Working with Multiple versions installation documents since yesterday. We have an AMD x64 multi-processor IBM server running SQL Server 2000 under MS Windows 2003 Enterprise SP1. SQL Server is installed in the "c:program files (x86)" folder. I wanted to verify that we were indeed running the 32-bit version of SQL Server 2000 so I also ran the @@version command from isql and it returns:
Microsoft SQL Server 2000 - 8.00.2162 (Intel X86)
Goal:
We need to install SQL Server 2005 Enterprise Edition 64-bit in a side by side installation. We will be migrating the SQL 2000 x32 stuff over to SQL 2005 x64 at a later date. My research shows I should be able to do this without any issues.
Have I missed anything or does it look like I am ready to move forward?
I am planning on installing SQL Server 2005 first and then install SQL Server 2000 as a separate instance on the same server. Has anyone had any experience with this setup? When I ran the SQL 2000 set up it didn't force me to create a new instance but I still did. I also installed the files on different directories c:program files just in case. If you have any experience of ideas about this configuration, please let us know. Thanks.
View 8 Replies View RelatedI have SQL Express 2005 with Advanced Services on a development box that I also want to have installed side-by-side with SQL Server 2005 Standard Edition so I can develop apps using either edition based on the features I need (or don't need). From what I understand from sifting through other posts is that side-by-side installs of these two editions is supported and I should setup a named instance for each edition (SQLEXPRESS for the express edition and MSSQLSERVER for the standard edition). Is this setup accurate or is there another/better way?
Also, does anybody know if side-by-side installations of Reporting Services is also supported? If I install SQL Server 2005 Standard Edition with Reporting Services, will there be two different report servers running in IIS? Since there are different features in Reporting Services between the two editions, I'm not sure how side-by-side installations will effect one another.
Thanks in advance for any help,

I have the following stored procedure to test scope of variables
alter proc updatePrereq
@pcntr int,
@pmax int
as
begin
[Code] ....
In the above script @i is declare in the if block only when the @pcntr value is 1. Assume the above stored procedure is called 5 times from this script
declare @z int
set @z = 1
declare @max int
set @max = 5
while @z <= @max
begin
exec dbo.updatePrereq @z, @max
set @z = @z + 1
end
go
As i said earlier `@i` variable exists only when `@pcntr` is `1`. Therefore when i call the stored procedure for the second time and so forth the control cannot enter the if block therefore @i variable wouldn't even exist. But the script prints the value in `@i` in each iteration, How comes this is possible should it throw an error saying `@i` variable does not exist when `@pcntr` values is greater than `1`?
I'm using SQL Server 2008 R2 BIDS to accomplish this.
View 7 Replies View RelatedI will soon be embarking on an upgrade of a transaction replicated database (Push) from 2005 to 2012 SP2.The publisher, distributor and subscriber are 3 separate machines.There databases will be detached, MDF and LDF will be copied across. Once attached, replication will be set up from scratch.
The name of the new servers are NOT the same as the existing ones.Should I completely remove transaction replication user the wizard and unticking the DB from being a database for transactional replication or just stop the log reader agent?How can I make sure the last of the transactions have gone across before I detach?Should I detach the subscriber first or the publication? Does it even matter?
Is there a better way of moving across the databases? I for one would have preferred to backup (.bak) then restore on the other side. I'd love to hear opinions on this as well.

I have downloaded and installed VS C# Express Orcas beta 1. It appears that Express editons ov VS can only connect to SQL2005 Express and not to a high end edition which I have on my computer. In one of the Orcas forums, it was suggested that I can install SQL2005 Express side by side my high end SQL 2005. To play it safe, I wanted to get a confirmation from this forum before I do that. Is a side-by-side installation ok? thanks.

Here is my case: I've a server running Windows server 2003 edition and SQL2000.
I've installed SQL2005 using the side-by-side method as described by MSFT docs. I've then copied the mdf & ldf files to new locations and attached the db in SQL 2005 management studio. Every thing fine. Next, I've migrated the DTSs using the DTS migration wizard. After this step I have some bad warnings in windows:
When I restart the server I get the following message: "mmc.exe Microsoft Management Console encountered a problem and needed to close".
Furthermore: I can't start the old SQL enterprise manager.
It shows another error "mmc.exe - Entry point Not Found" and closes it self.
The MSFT support page on this error relates it to Windows XP but my system is running Windows server....
Any one has any idea why this is happening?
Any suggested course of action?
Many thanks
