2 Databases On 2 Servers, 1 Query?

Jan 25, 2008

Hello,

We have adedicated MS-SQL Server for our CRM database and we have another MS-SQL database server for in house applications, written in c#.Net 2.0. To avoid duplicating information already in our CRM database, it would be nice if we could build a query that combined columns from both data sources.Example





Code Snippet

CRM database on Server1
Table Accounts


Columns
AccountID UniqueIdentifier Primary Key

Name NvarChar(50)



Application Database on Server2
Table Transaction


Columns

TransactionID UniqueIdentifier Primary Key

AccountID UniqueIdentifier
Amount Money




Would it be possible to create a T-SQL statement that will select




Code Snippet

Select
Server1.CRM.Accounts.Name,
Server2.Application.Transaction.TransactionID,
Server2.Application.Transaction.AccountID,
Server2.Application.Transaction.Amount



From Server1.CRM.Accounts INNER JOIN Server2.Application.Transaction




ON (Server1.CRM.Accounts.AccountID = Server2.CRM.Transaction.AccountID)


I appreciate there will need to be 2 connections and therefore some credential information would need to be passed too.


Is anything like this possible? I do not wish to copy the Name field from Server1.CRM.Accounts to Server2..Application.Transaction as this is duplication and any change to the value of Server1.CRM.Accounts.Name would not be reflected in the results.


Many thanks for any information provided.

How To Access 2 Databases On Separate Servers From Within The Same Query

Apr 10, 2008

Hi,

Im trying to access data from a database on another server in a SQL 2005 query.


use Bury2k29.ServiceDeskForms
select .......


but I get the message


could not locate entry in sysdatabases for database 'Burky2k29'. No entry found with that name. Make sure that the name is entered correctly.


Bury2k29 is the name of the server, and ServiceDeskForms is the database I want to access.

When I open a blank query and enter only the code to access that database it runs fine.

Any ideas?

Connect 2 Databases On 2 Servers ???

Sep 4, 2007

 Hi, If you have  2 databases with the exact same table columns, and in the first database in a table column the indentidy seed starts at 1 and finishes at 32,000 can you attatch a second database so that the indentity starts at 32,001and carries on. What happens if you create a site and run out of disk space and need to attach another database which is located on another server??? I am really confused about this.Hope someone can give some links to some articles about this as I can't find any information about it.How can this be done? Thanks

Transferring Databases Between Servers

Feb 15, 2002

I need some advice on copying databases, stored procedures, views, logins ..etc from a SQL Serevr 7.0 server, to a new SQL Server 2000 server.
Is it better to backup the databases on one server and then restore them to the other. Or id it easier to use the Wizards to Import everything from new server, or to Export everything from the old server ?

Any advice would be appreciated. I need to ensure that I do not miss anything, in particular Stored Procedures in the old master database.

Synchronize 2 Databases On Different Servers

Apr 10, 2006

Hi,

I was wondering if the following is possible: I have 2 SQL Express servers on different machines. One holds the production and one the development database. On a request basis I'd like mirror all the data of the production database to the development database. Right now I have to stop the sql engine, zip the mdf, send it over, attach it to database, etc. and that's quite cumbersome. So, is there an easier way to do this? If not with SQL Express, is it possible with the full version?

Thanks,

Tom

Exchange Data Between Databases On Two Servers??

May 29, 2007

Dear all
 
I have tow server on the same intranet. One server has a sql server 2000 database and the other one has SQL server 2005 databse.
 The sql 2000 database has a table called employee. When ever a new employee is inserted in the database i would like the same values to be sent to the sql 2005 database. But this cant be done on the application level. It has to be done in the database. The application level can not be changed.
I was thinking a trigger but how to achieve the writing from one database to another. If they were on the same server then it would be easier but because they are on different servers i dont know how to do it.
 Has anyone had similar issue before?
Any help is apreciated.
 
Sincerely
Dan

Restoring Encrypted Databases Between Different Servers

Jun 20, 2007

Hello:

I'm working with two sql servers instances, ServerA and ServerB, which run under two different service accounts on different machines. They both have a database, DatabaseA, that has some encrypted fields.

If I take a backup of DatabaseA on ServerA and restore it on ServerB, I need to re-encrypt the Database Master Key (DMK) with the Service Master Key (SMK) as follows:

OPEN MASTER KEY DECRYPTION BY PASSWORD = 'pwd used to encrypt DMK'
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY

However, if I again take a backup on ServerB and then restore it on ServerA, I can use the DMK on ServerA without re-encrypting it with the SMK.

Shouldn't I have to re-encrypt the DMK with the SMK everytime I restore from a backup that was generated from a different server?

Thanks,
Cyndi

Question On Restoring Encrypted Databases On Different Servers

Jul 3, 2006

I have run into problems trying to use backed-up encrypted databases. I have an ASP.Net/SqlServer 2005 website for which I have production, test, and development environments, each on its own box. I have set up encryption using Master Keys, Certificates, and Symmetric Keys using the following commands:

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password'

CREATE CERTIFICATE CERTIFICATE_NAME WITH SUBJECT = 'My Website'

CREATE SYMMETRIC KEY KEY_NAME WITH ALGORITHM = TRIPLE_DES ENCRYPTION BY CERTIFICATE CERTIFICATE_NAME.

All databases have the same certificate and symmetric key names. The Production database has a different password than the development and test databases.

I am running into problems when I back up the development database and try to move it to the test environment. When I do the move, and then try to access the encrypted data, I get an error "An error occurred during decryption", even though they are the "same" database (I originally detached and copied the development database to the test box when I set up the test environment) with the same password.

I then try the following commands, which I used when I brought the development database over to the test box the first time:

OPEN MASTER KEY DECRYPTION BY PASSWORD = 'password'

ALTER MASTER KEY REGENERATE WITH ENCRYPTION BY PASSWORD = 'password'

This caused the following error:
"An error occurred while decrypting certificate 'CERTIFICATE_NAME' that was encrypted by the old master key. The FORCE option can be used to ignore this error and continue the operation, but data that cannot be decrypted by the old master key will become unavailable."

So, how do you set up encrypted databases so that you can backup from one database server and restore on another? This problem will be very important when I set up a backup production database server.

Two Databases/servers - Can I Connect To Both To Create New Table On One Server?

Nov 20, 2007



Good morning all,

I need to create a new table on a SQL Server 2005 Database, but the data needed for the table is kept in different databases on different servers.

Half the data is on the SQL 2005 database, so that shouldn't be too much of a problem, but the other half is on a SQL Express database on a different server, is it possible to write a T-SQL query to retrieve this data on the other server?

Normally I use a create table + insert into kind of query to create custom tables but I don't know how to connect to the SQL Express server/database using T-SQL (if it's possible at all?) to do this.

Any tips, hints, ideas very welcome. Please use small words and short sentences.

Thanks,

Paul

Restore SMK And System Databases (credentials And Linked Servers)

Apr 28, 2008

Hi there



I have a concern about restore whole SQL server environment.



1st server:



x86 SQL Server 2005 EE SP2 + hotfix 3159 is installed on Windows 2003 SP1 R2. SQL Server is running under Local System Account. Server is not part of AD.



2nd server



Win XP SP2, x86 SQL Server 2005 DE SP2 + hotfix 3159. SQL Server is running under Local Admin Account. Server is part of AD. Server has Credentials and linked servers





I'm trying to move all databases from server 2 to server 1



For this I am doing:

1) Create backup SMK

2) Detach all user databases

3) Backup all system databases

4) Copy all this stuff to server 1

5) Run Server 1 in single-mode (-m)

6) Restore master database

7) Try to restore backup SMK that was done on step 1 and get this error message:



Msg 15329, Level 16, State 11, Line 2
The current master key cannot be decrypted. If this is a database master key, you should attempt to open it in the session before performing this operation. The FORCE option can be used to ignore this error and continue the operation but the data encrypted by the old master key will be lost.


My understanding is that credential secrets, linked server login passwords are lost and should be recreated. DbMK can be restored using passwords.



As far as I know this can be avoided if the same domain account is using for both servers. But the question still this - if I have stand alone server, using local system account for the SQL Server service and have encrypted objects - I cannot restore SQL Server on another box (say in case disaster lost original one) without loosing credentials and linked servers even if I have all backups including backup of SMK.



Sounds gloomily for me. Any idea what I missed?

Setting Up SQL Server Encryption Between Multiple Servers And Databases

Feb 23, 2007

Greetings.

I have a setup/deployment question regarding SQL Server Encryption.

Internal database encrypts data in 3 different tables. This could execute on any one of 6 different servers.
The tables with encrypted data are replicated to another database on different servers (3)

How should the keys/certificates be created so that the data in the replicated database can be decrypted?

In my test scenario so far, I have been unable to have the second database decrypt the data that was encrypted on the first database (currently on the same server).

-- Create Database Master Key
CREATE MASTER KEY ENCRYPTION BY
PASSWORD = 'p@ssw0rd'
GO

-- Create Certificate
CREATE CERTIFICATE MyCertificate
WITH SUBJECT = 'My Data Encryption Certificate',
EXPIRY_DATE = '10/31/2010';
GO

CREATE SYMMETRIC KEY MyKey
WITH
ALGORITHM = AES_256,
IDENTITY_VALUE = 'My Symmetric Key',
KEY_SOURCE = 'Unique phrase that will be used to secure the key'
ENCRYPTION BY CERTIFICATE MyCertificate;
GO

Advice Needed - Regarding Data Transfer Between Databases On Seperate Servers

Aug 29, 2007

Hello everyone,
Here's my situation...
I'm running a web service which involves 51 seperate servers and databases.
There are fifty licensee servers (One for each US state) and one corporate server.
Each night I need to upload sales and membership data from the licensee's databases to the corporate database to compile reports.
The application platform I'm using is ASP.NET 2.0 and the the database is SQL2005 express.
I want this process to be run automatically, so I believe it's a scheduled windows service I need to setup up in .NET to make the data transfers.
If anyone has already set something up like this, or knows the steps to take? I would love to have your input.
Thanks in advance,
Robert

Creating A Database From Multiple Databases Accross Multiple Servers

Sep 13, 2007

Hi,

I'm trying to create a database that takes specific information from a number of databases on different servers to make some reporting that we have much easier.

I'm pretty new to SQL so I'm not sure of the best way to proceed. I read an article that suggested I use the OPENROWSET command. The problem is, the version of SQL that came with one of the programmes we use is limited and will not allow you to turn on the allow "Ad Hoc distributed Queries" so the SLQ statement will not execute.

I'm confused why it won't let me to connect through ODBC as I've created a web page that selects data from this database with no problems!

Here is the SQL statement that I've written to make sure it is the correct one (on the msdn library page it said that this was the ODBC connection):

SELECT a.*
FROM OPENROWSET('MSDASQL','DRIVER=(SQL Server);SERVER=APPOLOACT7;UID=sa;PWD=***************',
'SELECT * FROM MDCTestAndDev.dbo.TBL_CONTACT') AS a



I've also created the ODBC connection using the tool on Administration Tools>Data Sources ODBC

Any help would be greatly appreciated (also any ways of selecting from one database and inserting it into another will be helpfull)

Thanks

Hi,

I am a newbie to SQL and learning as I go.

I am currently trying to write a SELECT that returns the difference between 2 identical tables in 2 different SQL databases on 2 different SQL servers.

I believe I have setup the linked servers properly.

Here is the select I wrote;

select *
from [dbnameA].dbo.Item
where not exists
(select * from [dbnameB].dbo.ItemSD
Where [dbnameA].dbo.Item.IMA_ItemID = [dbnameB].dbo.ItemSD.IMA_ItemID)

The error I receive is;

Server: Msg 208, Level 16, State 1, Line 1
Invalid object name 'dbnameB.dbo.ItemSD'.

Any suggestions are greatly appreciated!!
Thanks,
