How to find Server Name login into SQL Server by Management Studio?

I have a question. Few days ago i installed SQL Server Management Stuido with all packages in it. My Connection string that im using with my MVC or WebApi apps looks like this:
"ConnectionStrings": {
"DefaultConnection": "Server=(localdb)\\MSSQLLocalDB;Database=(name here);Trusted_Connection=True;"
}
I can still manage my databases by SQL Object Explorer in visual studio, but my question is where find my Server Name? Whatever i write, i cant acces to my local database server
How to get into Management Studio? Where i can find my Server Name?
You said you have installed SSMS, what about the server installation?
If the server has been installed successfully, try localhost instead of localdb. A dot(.) will also work as local host. The server name is provided while you install the server by you after selecting the named instance. If you leave it as default instance the pattern followed by sql server would be something like MSSQLSERVER......
Problem solved:
All you need to do is to click on Add SQL Server button in SQL Server Object Explorer. Then, in Browse tab click Local, then on your Server. Now you can see Server Name Label that you can login into Management Studio

How do I create an SQL Server?

I have a very fundamental and basic SQL question. Using Microsoft SQL Server Management Studio Express, how do I create my first Server? For that matter, how would I create it using any other required software tool?
I took a look at Sql Server Configuration Manager and I saw SQLEPRESS running as a SQL Server. But when I added that in to the start up widow for MSSM Studio Express, as the server name, it threw an error saying it cannot be found or does not exist. It seems that this is not the right kind of server.
To connect to the local instance of SQLEXPRESS, you will need localhost as the server name.
This is a fairly comprehensive guide on how to create a database once you have connected. All the steps won't apply to using SQL Express, but the gist of it is there.
In Object Explorer, connect to an instance of the SQL Server Database
Engine and then expand that instance.
Right-click Databases, and then
click New Database. In New Database, enter a database name.
To create
the database by accepting all default values, click OK; otherwise,
continue with the following optional steps.
Based on this comment:
Trying .\SQLEXPRESS in SQL Server Management Studio Express throws an error that says that "This version of Microsoft SQL Server Management Studio Express can only be used to connect to SQL Server 2005 servers". So this is the problem, I think.
.\SQLEXPRESS is the correct server name, but you have the wrong version of client tools (SQL Server Management Studio). To find out the version of SQL you are connecting to, there are a number of suggestions here: https://www.mssqltips.com/sqlservertip/1140/how-to-tell-what-sql-server-version-you-are-running/
But since you can't connect yet the easiest thing to do is go searching for sqlserver.exe, right click, properties, version. If you have multiple version you need take note of the folder that it's in and check the SQLExpress one. You can also check in services.
Once you've worked out the version, download and install just the management tools for that version.

Unable to import/deploy database to SQL Azure: "The service objective (Business/Web) specified is invalid."

I'm trying to move my databases to a newer Azure subscription. I used to simply click "Deploy to Azure" on a local database from SSMS and have it deployed to a specified Azure server. Importing/Exporting a BACPAC file also works. However, I can't seem to do any of this on the new server. I keep getting the error:
"The service objective 'Web' specified is invalid."
Googling around, I found this thread explaining the need to update the CREATE DATABASE template to accommodate Azure Databases (Azure upgrade, I'm guessing). However, the hotfix provided is specifically for SQL Server 2014 and I'm using SQL Server 2012. I checked other cumulative updates for 2012 here but found no fix for the issue.
Is there any other way I can fix this without having to upgrade to 2014?
Just to summarize my software versions:
SQL Server 2012
SQL Management Studio 11.0.2100.60
Local database: SQL Server 10.50.16000
Old Azure server: SQL Server 11.0.9230
New Azure server: SQL Server 13.0.15
You are getting this error because the latest V12 servers are not supporting the Web and Business Editions anymore. If you don't want to upgrade to SSMS 2014, you can create a V11 server and import your DB on this server. However this is only a temporary solution as Web and Business edition databases will be retired in September. At this point you will have to work with the latest tools to avoid this problem.
There is a Hotfix for it you can download and install on your machine. Please navigate to:
https://support.microsoft.com/en-gb/kb/2936603
You need to enter your email then download link will be sent to your email address. Then install it on your machine and you can see the following options:
Install the database as a Data Project into Visual Studio,
Set the target framework in the properties window to SQL Azure,
Build the project and resolve any unsupported issues.
Publish to your azure site.
I have tried the above and did not work for me - this solution worked!

Unable to connect to sql database server

Yesterday, I installed SQL Server 2008 on my PC. It was working perfectly, but now when I am trying to connect to the database engine, it generates this error:
Try using this.
This will only work if you are trying to connect to the database on the same machine. If you are writing software to connect to a remote database, you will need to work out what the connection string needs to be. This website may help you. ConnectionStrings

Connection is busy with results for another hstmt
Am tried with Sql native clinet , but i gives lot of troubles for me, so am using sql-server driver,
please any one help me to fix this problem, or give a steps to migrate paradox to sql server wihtout using 3rd party componets and ado,,,,
Try to set MARS_Connection=yes for your DSN.
SQL Server Driver has few issues when it works with SQL Server 2008. So, consider to use SQL Native Client 10.
