没有由SQL Server 2008 R2创建的实例

Question

I have a problem with SQL Server 2008 R2, when I try to connect to server it gives me the following message:

TITLE: Connect to Server

Cannot connect to (local).

ADDITIONAL INFORMATION:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
(Microsoft SQL Server, Error: 2)

I found a couple of solutions for this, one of which told me to go the configuration manager and check the instance created by SQL Server. There was none. I found only this:

I need to learn SQL Server for a job, and I don't know what to do.

-- UPDATE --

I reinstalled SQL Server 2008 and some errors might have something to do with my issue..

errors in reinstalling

note: the first time I installed I was basically clueless, I might had the same errors before and I simply didn't notice..

Answer 1

You need to install SQL server and SQL Server studio management tool. Seems you are trying to install SQL Server 2008.

• Go to this link and download the version of SQL Server 2008 you are after 32 or 64 bit https://www.microsoft.com/en-au/download/details.aspx?id=1695
• Then install a Microsoft SQL Server 2008 Management Studio. https://www.microsoft.com/en-au/download/details.aspx?id=7593

If you have windows 8.1 and upwards you can install the newer version of MSSQL which comes with Management studio. https://www.microsoft.com/en-us/sql-server/sql-server-downloads .

Answer 2

This seems you only install SQL Server Management studio not whole SQL Server DBMS so you need to install SQL Server and then try again.To check that SQL Server is installed on my PC or not You can follow these Steps

1.In Window Run Type `services.msc` 
2.Check that SQL Server Service is present or not
3.If Present Then Check in Running Mode or not.
4.if not here still SQL Server is not installed

Hope this helps you
