I'm developing a web app in a testing environment with test sql servers and databases. I'm currently adding a linked server and accessing the databases and tables in the linked server using [Servername].[DatabaseName].dbo.[TableName].
But after pushing it to production the DB servers name will change. So should i need to open each and every stored procedure again and change the server name?
What is the usual practice?
Thank you.
The link name need not be the same as the actual target server name. The easy solution is to use the same linked server name on both the development and production servers, just link to different actual servers. A development server might actually link to itself, for example.

I just got finished creating a VM in Azure and called it vm123. I was trying to use that VM when creating my SQL Server.
When I create a SQL Database in Azure, it forces me to either create a server or pick one from dropdown.
Why can't I see my vm123 in the list?
I can create a new one alright, which is what I did, since my VM did not appear in the dropdown. How do I remote into it?
See screenshots...
You are confusing VM with the Database server, the one asked in the dropdown is a SQL server not a VM. Those two are two different services on Azure.
To fix this create a SQL server resource first and you should be able to see that in the dropdown when you create the database.
Azure SQL Database is a managed service and the underlying infrastructure is shared across tenants.
If you really need access to the host then you'll need to choose from one of the following:
Create a SQL Server VM (includes licensing but at a higher operational cost)
Create a Windows Server VM and install a SQL instance on it. You must license it yourself accordingly.
I am about to begin a personal project to build my skills in the .net environment. I am familiar with SQL Server Management Studio and how to create a database in it but I discovered how to make a local database in Visual Studio as well. My program is only going to require local database access as it will be used for individual inventory systems rather than connected ones. Am I ok to use the onboard tools in visual studio and create a local databasse or should I be using the SQL Server Management Studio?
When you use the Local Database item template in VS, it creates a SQL Server CE data file (SDF) and adds it to your project. When you use the Service-based Database item templete, it creates a SQL Server (Express) data file (MDF) and adds it to your project.
The advantage of using the VS tools is that the data file becomes part of your project and can therefore be easily deployed with the compiled application. As such, the database is basically part of the application.
If you choose SQL Server CE then you don't need a server installed on the user's local machine. They can install SQL Server CE or you can install it with your app if you want, but you also have the option of simply deploying a DLL with your app and it will work.
If you choose SQL Server Express then the user actually needs a SQL Server instance installed on their machine. To be honest, I'm not 100% sure whether that instance must be SQL Server Express or it can be a full SQL Server instance too. It would usually be SQL Server Express though, which you can install and even download automatically when you install your app, depending on the deployment method you choose.
If you use the VS tools to create an MDF data file then your connection string will contain the Data Source and AttachDbFilename attributes. The Data Source will generally be ".\SQLExpress", i.e. an instance named "SQLExpress" on the local machine. That instance name is not required, although it is the default for SQL Server Express, but it must be on the local machine. The MDF file gets attached at run time and detached again when you're app is done with it. It will also usually be attached to a user instance, which means that other users can't see it, even when it's attached. Note that, in later versions, the LocalDB feature of SQL Server may also be utilised.
If you create your database in Management Studio then it's not actually part of your app. It will be permanently attached to the SQL Server instance so, everyone will be able to see it and open it, assuming permissions allow. Creating the database during deployment will be an extra step in that case. You might create a backup and restore that during deployment or generate SQL scripts that get run. In this case, your connection string will contain the Initial Catalog attribute to specify the name of database to connect to, as well as the Data Source attribute. This option is required if you want multiple clients to be able to connect to the database.
In short, if you are only going to be accessing a database from the local instance of the one application then creating a database in VS is OK and probably a good idea. Whether you choose SQL Server CE or SQL Server Express may well depend on what level of functionality you need.
I am looking to create a database server that can be used to store data using a VB.net application. When I initially installed SQL Server 2005 Express edition, I believe I installed this using the LocalDB option.
As it stands my application is a simple tool which utilises the Process.Start command under certain situations, depending on user input, to launch Game Servers for use at a gaming LAN I assist in running.
I wish to progress the application by being able to update, delete and query a database created in SQL Server 2005 Express. I understand the use of connection strings etc, however I am wondering if the installation using LocalDB will mean that I cannot connect to the server to process the data I require.
Can I continue to use the LocalDB option and create a Database Server for specific use using my application or is a different installation option required?
Secondly, can someone point me in the right direction of how to create a new Server for this purpose? All of my searches so far have provided results for creating a database only, and not the server.
I have a couple questions about what you are trying to do.
First, why are you installing SQL Server 2005? It was released almost a decade ago.
I would go with 2012 express edition.
http://www.microsoft.com/en-us/download/details.aspx?id=29062
Second, install the management tools. SSMS is a nice GUI to do work in.
Third, If you are spinning up anything other than express, there are licensing costs which are quite high. 9K for standard and 25K for enterprise per socket or such.
Here are the versions and features list from microsoft.
http://technet.microsoft.com/en-us/library/ms144275.aspx
Last but not least, having the express edition on another computer is fine. However, you will have to use a network protocol such as TCP/IP instead of shared memory.
It will take longer to send Tabular Data Stream (TDS) to the other computer versus talking to memory on the same computer.

Good luck with your project.
You can use a local instance of SQL Server just fine, if you want to set up a separate server for some reason then you'll need either a 2nd machine on which to install SQL Server, or to spin up a virtual machine. If running Windows 8 (and barring hardware limitations) you have Hyper-V at your fingertips.
This is not a complete answer for you but may give you some things to think about.
First you might want to think about your choice of database. If you don't have a compelling reason for using 2005 you will probably at least want to move to SQL Express 2008.
Second, to answer the part about creating a server... A server is something that serves data. In a general sense a computer configured to be contacted by external machines and respond with data is a server. A web server runs a program like IIS or Apache to respond with web pages. A database server contains a database and allows connections to that database. So as long as you install the database on a computer and configure it to allow external connections, you have your database server.
In MS SQL there are several things that need to be set up to allow a database to accept external connections. One is that the SQL Server Browser service will need to be active. Another is that the database itself will need to be configured to allow external connections (SQL Authentication type probably).
Hope this helps.
Addition:
SQL Remote Connection Configuration
Disclaimer, I don't have SQL Express 2005 installed but I think the settings are found in the same place in 2008. If the info here is not exact to SQL Express 2005, the general terminology used here should be enough to get you headed in the right direction to find the specifics.
While viewing the database in Server Management Studio or Enterprise Manager, right click the database server instance name (the root of the tree) and select properties. There should be a section title Connections and within this section there should be an option "Allow remote connections to this server". Make sure it is checked. The other setting you need in this properties menu is under the security area. There is a radio button for "Windows Authentication Mode" and "SQL Server and Windows Authentication Mode", you want the second that allows both.
The next step you have may be to create a new user, add a password, and connect the user to the database. That will give you the credentials you will use in your database connection string while programming. I usually add new users through the security section of the database then set the User Roles for each database that I need to connect to. It is good practice to limit the permissions to those needed by the application. Typically this is read and write, but sometimes you can get away with just read. The less the better.
I want to share my SQL Server 2008 R2 database between some computers on the same network without using a Server. How can I do so? I mean i just want two users access the same Database through A network or LAN. Both can use database,update database,delete data from database
is it possible ?
The file: mdf MS SQL can not be shared directly.
Although, once installed MS SQL any user with privileges on the database can access it.
It is not necessary to share the MDF file. MS SQL is responsible "sharing" the users enter data accessing it.
Greetings.
SQL Server can only be installed on a Windows Server system (except for the Developer's edition, and SQL Express).
However, all versions (except CE) can be shared among multiple clients. Just start up the server, make sure that the TCP protocol is enabled (using the SQL Server Configuration Tool), and that your Windows Firewall is not blocking port 1433.
A server just happens to be a term used for otherwise a "normal" computer. The designation server usually means that it is dedicated for a certain task. Technically speaking, any computer can be a server--even your own workstation while you are using it for other tasks. So, just put the database on one of the user computers which is on the network (hence accessible to desired users on the network) and go for it.... Good luck!
We have a DB server with a couple web app db's on there (don't get a ton of traffic). We'd like to make use of the server and allow it to be the DB server for sharepoint. I'm assuming it's not good practice and that sharepoint should have it's own exclusive db server. Am I right in that conclusion, or is it alright if we put the database on a server that already hosts other databases.
You can install SharePoint on an existing DB server, sure. Unless your environment is going to be huge, I don't see why you would give it its own DB server. It will use an embedded SQL Server instance if you want, but you'll get better performance if you have the full-blown version. We're running a few SharePoint apps on our DB server with a number of other applications.
The way in which I solve this is to install a second SQL Server instance dedicated to SharePoint, as SharePoint likes to have a lot of control over the database and spews all sorts of stuff such as logins, etc. across the instance, which you really want to separate from your standard line of business instance.
The added bonus is multiple SQL Server instances on the same physical machine are included in your licence.
Be careful with the SQL Server collation. I think SharePoint requires a particular setting for this. See http://www.moss2007.be/blogs/vandest/archive/2007/07/24/sharepoint-2007-and-sql-server-collation-latin1_general_ci_as_ks_ws.aspx for one reference.
Prior to centralizing our environment we had many Sharepoint sites located on servers with existing applications. I'm not a fan of adding an additional named instance as this increases the administrative overhead for the DBA. You have to know how much use you expect of your Sharepoint instance then measure the resource utilization of your existing applications balance it from there.
