On my work we have a database on our server. But for some clients we implement on ther server the database. The problem comes when We change a table design on our server. We need to replicate that change manually on every client server.
Is there a way to see the difference of a table or all tables to know what tables or store procedures needs to be updated.
Here is a post on stackoverflow with list of tools to do a Schema compare: What is a free tool to compare two SQL Server Databases?
Additionally if you have VS 2010 Premium or Ultimate you can do a schema compare : http://msdn.microsoft.com/en-us/library/dd193250%28v=vs.100%29.aspx

I am working on migrating an application from one server to the other. According to the connection string of this application, it is touching different databases. Meaning a view query in DB1 will touch a table in DB2. So while migrating this application, I constant get to see chain of 'Database unavailable' errors and every time I see such error, I have to migrate that specific database.
I am wondering, since we have ER diagrams to know about relationships between tables in a database, is there any way in SQL server to know the relationships/linkages between different DATABASES in a server? Are there any tool that does this?
Depending on number of databases you have, here would be a somehow quick way you can find that out (number of required search = number of available databases in the server):
Use 'SQL Search' application of Red-get
(https://www.red-gate.com/dynamic/products/sql-development/sql-search/download)
and search for the other database names one after another by selecting
your database of interest. Select all objects.
If you have metadata oriented design (a Stored Procedure looping through the names of different other Stored Procedures / Functions from different databases which are stored in a table as metadata and executing them with a wrapper Stored Procesure), then you will have make use of SQL Locator software (http://www.sqllocator.com/Downloads.html) to search for database names in SQL Table values.
Both of the above software are free.
You need to have SSMS (SQL Server Management Studio) installed to be able to use this application. After installation, ‘SQL Search’ will be directly available in your SSMS as an add-on.
SQL Locator can be directly used by providing the SQL Server name and your SQL Server credential.
Note:- The above steps will help you find out the referenced databases from a certain database within the same SQL Server. If you need to find out databases from Linked Server (I do not believe your question is asking that anyways), then you will have to smartly utilize the same above tools to find the external server reference by searching the external server name.
I need to confirm if a particular table ever existed on our SQL Server. Is there an existing script or method one can use to list all dropped databases in an SQL server?
There is a built-in report you can access through SSMS called Schema Changes History. You can run this to find what you're looking for.
I'm creating the front-end for a project and I made a copy of the back-end database from the company's server and put it on my computer. I needed to make some changes (a few new tables and two new columns in an existing table) for security roles and other things so I duplicated the copied database and made my changes on the new one.
I want to deploy my project to the company's server now but we need to modify the original back-end database. I need to generate a SQL script that finds the changes between the old-database and my newer database, which can be run on the old database to create the new tables and columns. The script should retain the data from the old database and NOT add any junk/testing data I made in my new database.
By the way, I'm using SQL Server 2008 R2 and the old database on the server is on 2005. I've been looking around for utilities to use and found tablediff. However, it looks like it will copy the data and I can't see an argument on the information page to toggle this.
I'm sure it's simple but I'm not really sure how to do this. Any help would be appreciated. Thanks.
By far the solution I trust most to handle schema comparisons is Red Gate's SQL Compare:
http://www.red-gate.com/products/sql-development/sql-compare/
It has a companion called Data Compare which is designed specifically for data. You can grab the free trial to see if it does what you need in this case.
There are other options as well, for example SQL Server Data Tools has this functionality, though I haven't tested it to any degree that I could compare feature sets, performance, etc.
I've also blogged about why you want to use a tool and just pay for this functionality, rather than solve it programmatically yourself. The post also mentions a variety of alternatives if budget is a primary blocker:

I've been tasked to create an internal site for my company to document the replication of tables in our databases. I'd like to make the site dynamic, but to do this I'd need to query sql server to figure out how each table replicates. I know you can query sql server to figure out things like column names and many other features, can you query sql server to determine how a table replicates, and if so is there a good document to show me how or get me started? We're running sql server 2005 and c# or tsql are the preferred languages for me to use for this.
Try taking a look at the documentation for the syspublications and syssubscriptions system views in the Distribution database. Does that provide you with the information you need to build your site? If not, what else are you looking for? I've included links to the documentation for those views below.

I'm working on a legacy project, written for the most part in Delphi 5 before it was upgraded to Delphi 2007. A lot has changed after this upgrade, except the database that's underneath. It still uses MS-Access for data storage.
Now we want to support SQL Server as an alternate database. Still just for single-user situations, although multi-user support will be a feature for the future. And although there won't be many migration problems (see below) when it needs to use a different database, keeping two database structures synchronized is a bit of a problem.
If I would create an SQL script to generate the SQL Server database then I would need a second script to keep the Access database up-to-date too. They don't speak the same dialect. (At least, not for our purposes.) So I need a way to maintain the database structure in a simple way, making sure it can generate both a valid SQL Server database as an Access database. I could write my own tool where I store the database structure inside an XML file, which combined with some smart code and ADOX would generate both database types.
But isn't there already a good tool that can do this?
Note: the application also uses ADO and all queries are just simple select statements. Although it has 50+ tables, there's one root "Document" table and the user selects one of the "documents" in this table. It then collects all records from all tables that are related to this document record and stores them in an in-memory structure. When the user saves the data, it just writes the document record and all changed data back to the database again. Basically, this read/write mechanism of documents is the only database interaction in the whole application. So using a different database is not a big problem.
We will drop the MS-Access database in the future but for now we have 4000 customers using this application. We first need to make sure the whole thing works with SQL Server and we need to continue to maintain the current code. As a result, we will have to support both databases for at least a year.
Take a look at the DB Explorer, there is a trial download too.
OR
Use migration wizard from MS Access to SQL Server
After development in Access (schema changes), use the wizard again.
Use a tool to compare SQL Server schemata.
