I have installed many SQL Server setups but I want to know how to install SQL Server without an instance name i.e. i want to connect to SQL Server with IP or server name only.
Installing an instance and connecting to an instance of SQL Server are two different things.
Every time you attempt an SQL Server installation you have to specify an instance (create a new one or select an existing one)
Connecting to an instance is a different thing.
For example if you want to connect to an instance through MS Management studio without writting the name of the instance you can define the connection in following manner:
ComputerName\IP,port
e.g:
MyPC\192.168.1.1,1433
In order to do this you need to install SQL Server as the default instance on the machine. When it is set as the default instance you no longer need to specify an instance name when connecting to it.

I use management studio and SQL Server. How to change server name from (LocalDbs)\MSSQLLocalDB to localhost? When I connect to server in connection string I want to call: server='localhost
I believe, it's not good idea to change named instance to default instance as it might conflict with existing default instance, and considering consequences. However, \InstanceName is really concern for the connection string, you could have custom port assigned to that SQL Instance so that your connection string would be server=localhost,portnumber.
Please have a look at this answer at DBA.StackExchange to learn more on connecting SQL Server with custom port and how to change the port#
If you still have concern to use port number in connection string server=localhost,portnumber. My advise is to restore the database on SQL default instance (need to be installed if not existed already), then you could re-direct the application to communicate with default SQL Instance, this case your connection string would look like server=localhost
You could do following, if you want rename the Server in any case:
sp_dropserver <old_name>;
GO
sp_addserver <new_name>, local;
GO
Installed SSMS 2017 version. When I launch it first time, it asks for server name to connect to. I installed SQL server 2014 already. But I don't know the name of the server. I tried giving server name as "local". But it wouldn't accept. It says "Cannot connect to to local" Error: 53
Since I installed SQL server on my local machine, "local" should be acceptable name as a server to connect to from SSMS.
server name?
.
localhost
127.0.0.1
Any of these will connect to sql server running on your local machine.
If you installed sql as a named instance, then .\myinstance, localhost\myinstance, etc
You can use (.), or local or localhost.
If you used named instance, follow the next:-
Use Browse for more, for getting the accurate server name as next screen shots;-
and under Database Engine, you will get the accurate server name
If you have Db connection you can use this command
select ##servername + '\' + ##servicename
you can also check SQL Server Configuration Manager.
In Configuration Manager you need to find SQL Server Service. When you Double click the SQL Service and navigate through Service Tab, you need to see SQL Server Name
It should be localhost, just setup my SQL server last month and had to find this information aswell.
You need connect using . only.
connect Local instance using .
One of our clients have SQL server default instance running on a non-default port. So, the connection string from our application should be servername,1234.
They don't want to create aliases on the MS SQL server.
Is there any different way our application can connect to it?
It is a default instance, so can I use servername\MSSQLServer
Thank you!
SQL Browser does not support connecting to a default instance with
servername\MSSQLServer
They don't want to create aliases on the MS SQL server.
That wouldn't help anyway. Aliases are created on the client computer, not the SQL Server.

I am facing server name problem in SQL Server 2012. When I click on configure distribution I get an error:
Unable to connect to server. Specify the actual server name.
I changed my server name and restarted the services but unable to connect through new server name.
Basically, I am doing this on local domain based server.
Kindly suggest a suitable solutions.
After you rename a SQL Server machine, you will also need to rename the SQL Server instance itself using:
sp_dropserver <old_name>;
GO
sp_addserver <new_name>, local;
GO
For more information, see Microsoft's article called Rename a Computer that Hosts a Stand-Alone Instance of SQL Server.
I think what your probably finding is that changing the Windows server hostname doesn't actually change the original SQL Server instance name which still gets used for certain services. Run the following on the DB engine:
SELECT ##SERVERNAME
You'll probably find a different value to what your expecting from the OS.
There isn't really a solution to this that I'm aware of without re-installing SQL Server on the newly named box.
Also be careful with names that exceed to the 15 character NetBIOS limit.
I have two instances of SQL Server 2008 Express and one instance of SQL Server 2012 on my development machine. We're developing an ASP.NET MVC application and use the expression data source=(local); inside of our connectionString in Web.config.
Now my question is what is the logic behind this expression? Which instance gets chosen and how can I change this behavior?
Using "local" you get the default instance which is usually the non-express SQL Server since by default in SQL Server Express installation the instance name is "SQLEXPRESS" and in full SQL Server installation by default you don't get an instance name unless you set it explicitly.
(local) just means means to use the SQL Server installed in the current MachineAny of the following three
"(local)" ,
"." ,
".\\SQLEXPRESS"
can be used to make use of the SQL Server installed in the current Machine.
Every instance has instance name, so you can specify source=(local)\INSTANCE_NAME.
You can check instance's and their names in sql server configuration manager.
When you use data source="(local)";
It means it connects to SQL Server database on the local server
