Can anyone help me in this issue:
How do we replicate database changes (like tables) from QA to production without losing Production data.
We already tried using the DTS export but it is dropping the destination tables before export which will result in data loss in the destination database.
My applications group wants to do a table transfer from one server to another as a means of refreshing the information on the target on a scheduled basis. That means that reports could be running against the target table during the transfer. This has introduced erroneous reports because the object transfer initially truncates the table, then transfers the data. If reports are running during the transfer, they might retrieve no data or only part of a table. I wrote a procedure to make a copy of the table to be transferred, then transfer that new table to the target machine, then drop the target table, then rename the transferred table. Now, I have the slightly smaller problem of doing a DROP TABLE when users are accessing the table. I can't set the database to 'dbo use only' because there are other tables in the database that must be available. Is this really a replication application?

I am still pursuing my studies. I have been recently assigned a project for building Database Application for my college's library. And there was no better option to implement it with VB.NET 2.0 & SQL Server 2005.
VB.NET 2005 & SQL Server Express 2005 are the resources at my disposal.
The problem is that the college already has a Library Management System in place, built in VB6.0 with Access. I have been asked to pepare the application from scratch. But the database obviously cannot be left out.
Now, can anyone suggest me an efficient way to port the Access database to SQL Server express. Also, the databse has been desinged poorly & is not properly normalized.
Can I port it to SQL Server Express with some slight modifications to its structure without any loss of data??????
We rewrote one of our legacy C#/asp.net applications that accesses a sql server 2000 database. The new database schema looks very similar to the old one. The major difference is that some of the atributes in the database tables are different. But pretty much we are using the same tables, plus or minus a few.
We need to import the old data into the new database. I have never had to undertake this type of thing before as I am not a DBA, but a developer. I feel a little scared about this whole process. My boss is open to us hiring a contractor to help with the process.
My biggest concern is the referential integrity of the database.
Can someone help me out. Does this sound like something that can be easily done or should I ask for some help.

Hi all,
I'm working on porting a solution running under WM 5 Pocket PC to Win32 but I got some problems with type definitions like CEOID, CEGUID... I saw that these types are defined in windbase.h (EDB definition added to preprocessors) ) which includes types and definitions usefull for database managment. Anyway this header file is not present in C:Program FilesMicrosoft Platform SDK for Windows Server 2003 R2Include, so I was wondering which is the header file I can use instead of it. Thanks
I have created a sql login account called "webuser" and has given public role in my database. In my asp.net application i build connection string using above account and its password . We give permission on store procedure for for the above account to execute .We dont give table level permission for the above account . When we run the application with the above settings it runs fine on test server . However Now i have transfered the databse object to live server with its permissions . Now while I executing the aspx page , I am getting above error . I have checked that the store procedure has execute permission for webuser account and dbo(i.e SA) has all the permissions for all database objects . Still why i am getting error ? (Please note , the thing is working fine in test server)
Pl help

Here is the scenario:
- I have one production database and one test database.
- In the test database i have done a few changes on the structure - mostly adding new fields in the tables.
- Now i want to apply the table changes to my production database.
Does anyone have any suggestions on how i should do that?
I mean, of course i could just manually check every field and update the changes - but that could take a while -
i guess there are some better ways this could be done, like:
- backup data
- delete tables
- recreate tables using structure of test database
- reinsert data
Is this the correct way? Are there any easy ways to do this?
The changes i made should not make problems regarding data that is already stored (like changing a string field to int)
Hi all,
I have a site which used a SQL Express database. On my development machine, it works perfectly. As soon as I move it to the production machine, it doesn't work at all. I am pretty confused by what is going on and I really don't want to install Visual Studio on my production machine just to debug it. I am hoping someone might have an idea what could be happening.
Oh, and I have tried setting Everyone to Full Control on the App_Data directory just to test. Still breaks. Below is my web.config connection string:
<connectionStrings> <add name="database_sqlexpress" connectionString="Data Source=.SQLEXPRESS; AttachDbFilename=|DataDirectory|MyDatabase.mdf; integrated security=true; user instance=true"/></connectionStrings>

Is there any tool available to migrate the data from the SQL Server
test database to SQL Server production database. Data Migration should
be based on a condition which can be given as an input for a table by
the user. The dependant tables also should be migrated based on the
condition. i.e data subsetting based on the matching conditions.
Ex : Salary > 2000
The rows of the table which matches the condition alone need to be
migrated for the corresponding table. Also its dependant table's
rows should be migrated based on the given condition. Please help me
with a tool which can automate this.
Thanks,

Hello,
I am trying to refresh a test database with data from a production database. Both database structures are identical, e.g. constraints, stored procs, PK, etc. I am trying to create a package in SSIS that accomplishes this task and I am having extensive problems. The import export wizard is out of the question because the constaints are not carried over, plus when I try to refresh the data using the import export wizard, it fails on 1 specific table because of a column in that table named "Error code". I think "Error code" is a micrsoft keyword, so it fails on this column. Does anyone know a workaround that I can do to accomplish this simple task, that could be completed in minutes using DTS. I understand that SSIS is not as straight forward as DTS, but this task is something that DBA's do on a regular basis and therefore should not be this difficult.
Any help would be appreciated,
David
I have question regarding SQL Transactional Replication methodology
1. Let's say successfully created SQL Transactional Replication and running / transferring data from publisher to subscriber
2. Now one day the source production / publisher SQL Server is down and the remaining DR SQL Server is up (subscriber)
3. Next day, we fixed and bring up the production / publisher SQL Transactional Replication server, then how can we sync back all existing data records from subscriber into publisher side ?
Our DBA is out for about 6 weeks. One of his regular jobs is to take a Database that is in our Prod environment and copy it to our Training environment.
I have backed up and restored to different servers before, however the Database name in Prod is different than in the Train environment in this case.
In other words I have a PROD database named DATABASE-XX that I want to copy to another SQL server and restore it to DATABASE-XX-TRAIN.
Is there anything special I need to do, other than backup on PROD, copy to TRAIN and restore to the corresponding DB in TRAIN?
I have a 20 GB SS2005 database that I would like to be replicated to a dev server for testing purposes. I might have some issues with the firewall blocking ports. I haven't read up on the specifics of how log shipping works yet, but I assume that is the best approach. A daily transfer would suffice.
A few options I am considering:
1. use the built in stuff, but I'm not sure it will work with our security settings, and if the trans logs are large it might be strained.
2. writing a small custom app to zip up the log file then ftp them down to the dev server. This could run nightly.
3. some third party util, such as FolderShare could transfer the log files
Any comments or suggestions?

I have a database with one 320 .mdf file and one 200GB .ndf file.
I would like to reconfigure my database to have four 200GB .mdf files. How do I get from here to there?
I have a windows forms application that I would like to put in production on several machines. Each machine will contain it's own data and does not need to be networked.
I can use my local connection right now to access the data, but I would like to change my connection so that it will work when installed on a client's machine.
My Current connection string looks like this:
Data Source=.SQLEXPRESS;AttachDbFilename="C:Documents and SettingsMYNAMEMy DocumentsVisual Studio 2005ProjectsInterimApplicationInterimApplicationInterim.mdf";Integrated Security=True;User Instance=True
I believe I could use something like this:
Dim connectionString as string = "Data Source=" & Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles) & "/InterimApplication/data/Interim.mdf;Integrated Security=True;User Instance=True"
However, I am not sure. Also, if the client does not install to the default directory, then this may cause the application to not work properly.
Lastly, I am not sure if the client machine needs any additional software on their computer in order for the application to be capable of connecting to the data source.
Any recommendations, ideas, comments, or general help is greatly appreciated.
I have searched hi and low for hours within the product and online - I cannot find how to have SQL 2005 produce a script to automatically repeat the creation of a database role I have tedious manually created.
I have tried "script object as, create to,<>" - single-liners are produced - no details. More single line results from "<Database>, All Tasks, Generate Scripts".
Am I missing something or is this a bug?
€¦also to note after review blogs and other sources the use of the SQL2005 methods related to security and new schema objects - I feel€¦ dreadfully wrong - what is claimed feels like hype, unsupported by examples and usage cases feels like we better just make all automated processes sysadmin; I know learning curves can be strong but I am not this green or that stupid - where are the DOCS/training materials?

I have been discussing this Service Broker issues in this forum for quite sometimes and sorry to bother u all again€¦ To make things more clearer before implementing in production environment I have few doubts and it should be clarified..
As discussed in the first link we can clear sys.conversation_endpoints by just giving ALTER DATABASE GPx SET NEW_BROKER WITH ROLLBACK IMMEDIATE. But my apprehension is that if we run this command on production server and it truncate this table€¦ what will be the impact and overall overhead on the system€¦ Is it recommended to give this statement on Production Server daily at less traffic times, to clear this table ?€¦ will it have adverse effect. I repeat I have downtime , I can even shutdown this server daily€¦
I also, just want to know why Microsoft has not looked into this aspects€¦ why the system itself is clearing the expired messages.. What is the thought behind this architecture
I have the script to run in batch€¦ but in high-level meetings it is always difficult to convince this architecture/process€¦
Thanks in advance
