Database created in sqlcmd but missing in SQL Server Management Studio I created a database named testbase in sqlcmd in SERVER\MSSQLSERVER. However, I cannot access SERVER\MSSQLSERVER. 

I also could not find testbase inside the server connection using Microsoft SQL Server Management Studio.

Appreciate any help / tips / hints.
Actually, I went to the wrong connection. It should be SERVER\MSQLSERVER rather than SERVER\MSSQLSERVER.
